The Oracle TO_NUMBER function is used to convert a text value into a number value.
It’s similar to TO_CHAR and TO_DATE, but converts a value to a number.
The number will also be rounded to a specified number of digits, and returned as a NUMBER value.
The syntax is:
TO_NUMBER( input_value, [format_mask], [nls_parameter] )
The input_value is the value to be converted to a number. Commonly this is provided as a string (e.g. CHAR or VARCAHR2) but can be several other data types as well.
The format_mask is the format that the output value should be displayed as. It must be a valid number format. This is an optional value.
The final parameter, nls_date_language, is used to work out how the output is displayed, such as how to display currency symbols. It’s also an optional value.

This is Manish from RebellionRider.com
----------------------------------------------------------------------------
As the name suggests SQL Substr function will return substring from a given source string.
Let's see the Syntax
Substr (source_string, start_pos, Substr_length)
As we can see SQL substr function takes 3 parameters. First one is Source string from which you want to extract the segment.
Second parameter is Starting position for sub string from the Source string.
And the third parameter is Substr_length which is the length for the substring.
First two parameters are mandatory to specify while third one is optional.
So we can say.
SQL Substr function will return a sub string of a specified length from the source string beginning at a given position.
First parameter source string can be of any data type CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB whereas both start_pos, Substr_length parameters must be number data type.
The returning result of SQL Substr function is of same data type of source string.
Let's see an example of SQL Substr function.
SELECT substr('www.RebellionRider.com',5,14) FROM dual;
Here in this query url of my website www.RebellionRider.com is our source string with the total length of 22 characters,
Now, I want to extract the name of my website that is, RebellionRider. So if you count the total length of the name of the website, it is 14.
That's why I have specified 14 as my third parameter of SQL Substr function which is substr_length.
Also the name of the website RebellionRider is starting from 5th position therefore I have specified 5 at second parameter of SQL substr function which is strt_pos or starting position.
Execute it.
Here is our result RebellionRider
When starting position is larger than the length of source string.
In this case SQL Substr function will return NULL as a result.
Let's do an example.
SELECT substr('www.RebellionRider.com',23,14) FROM dual;
As you can see here I have specified 23 at starting position and the total length of our source string is 22 characters
Let's execute
And the result is Null.
Second scenario
When the Substr_length is greater than source string
In this case the segment return is the substring from starting position to the end of the string.
For example
SELECT substr('www.RebellionRider.com',5,23) FROM dual;
Our starting position is at 5 means at the first R of RebellionRider and length of substring is set to 23 which is greater than the length of source string that is 22.
Execute.
As you can see we get a substring from first R of RebellionRider till the end of the source String.
Third scenario
When you supply numeric or arithmetic expression or a DATE instead of character as Source string to SQL Substr function
In this scenario
If you have supplied a numeric string instead of character as source string, the oracle engine casts them as a character when they occur as parameter to SQL Substr function.
And if you have supplied Arithmetic expression or a DATE then
The Oracle engine first solves or evaluates the Arithmetic expression or the DATE
Then casts them as a character.
Means if you have arithmetic expression in your source string then oracle will first solve it and then change or say cast the value of its result into character.
Let's see some example.
SELECT substr(50000-7,2,4) FROM dual;
Oracle first evaluates the arithmetic expression that is
50000-7 equals to 49993. And then oracle engine casts this result 49993 into a character string. Means 49993 will be a 5 characters string.
Starting position of substring is 2, that means from the first 9 of 49993
We specified the length of substring is 4 so we must get 9993 as our result.
Let's check execute

https://www.databasestar.com/oracle-greatest/
The Oracle LEAST function is a useful function, but I don’t think it’s very well understood.
It returns the least or smallest value in a set of values. You can provide the values, and use numbers or text values.
The syntax for the Oracle LEAST function is:
LEAST(expr1 [, expr_n])
The expr1 is the first expression to use for your comparison. Expr_n is one or more expressions to use in the comparison, separated by commas. This is optional.
So how is LEAST calculated?
If the parameters are numeric, the LEAST function finds the smallest number.
If the parameters are characters, the function finds the earliest value if they were sorted alphabetically (using their character values).
What data type is returned?
It depends on the parameters you provide. It could be the same as the parameters you provide, or VARCHAR2 if the parameters are all characters.
You can also use the LEAST function with dates.
It’s the opposite of the GREATEST function.
For more information on the LEAST function, including the SQL used in this video and the examples, read the related post here:

In this video I use the ROUND and FLOOR functions found in SQL. I use the ROUND function to round my figures to the nearest dollar and view the results to see how it rounds. I then round those same figures to the nearest tenth and hundredth. Using a negative number as my parameter will allow me to round to tens, hundreds, etc. The FLOOR function will just drop the decimal values without rounding.This video is part of a series of videos with the purpose of learning the SQL language.

https://www.databasestar.com/oracle-lpad/
The Oracle LPAD function is used to add extra characters to the left of a text value. This is called “padding”, and the function is called LPAD because the L stands for “left” and it “left pads” a text value.
It’s the opposite of RPAD, which pads characters to the right of the value.
The LPAD function can be useful for ensuring all values are the same length, or if there is another requirement you have for adding characters to the end.
The syntax is:
LPAD(expr, length [,pad_expression])
The expr parameter is the text value you want to pad or add characters to.
The length is the total length the expression or value will be after the padding has been done. It’s not the number of characters to add.
The pad_expression is an optional field and is the character or characters to add to the left end of the string. The default value is a space.
If the length specified in the function is shorter than the length of the string, then the string is truncated to meet the length.

https://www.databasestar.com/oracle-nvl-nvl2-logical-functions/
The Oracle NVL function allows you to check a value and return a different value if that value is NULL.
It’s great for using another value if the first one is NULL or an optional value, for example people’s phone numbers.
It’s also good alongside aggregate functions and grouping so you can see what the difference is between a subtotal row and an actual NULL value.
The syntax of the Oracle NVL function is:
NVL( check_value, replace_value )
The parameters are:
- check_value (mandatory): This is the value that is displayed to the user. It is also the value that is checked for NULL.
- replace_value (mandatory): This is the value that appears if the check_value is NULL.
The function can use many different data types as parameters: string, date, or numeric. However, both parameters need to be the same type.

Oracle tutorial : Conversion Functions In Oracle.
oracle tutorial for beginners
sql convert
This Oracle tutorial video will show how to use conversion function in sql oracle
TO_CHAR() , TO_DATE() , TO_NUMBER() these are mostly used functions.
Conversions functions are used to convert one data type to another type.
1)To_CHAR ( number | date, [fmt], [nlsparams] )
The TO_CHAR function converts the number or date to VARCHAR2 data type in the specified
format (fmt).
2)TO_NUMBER( char, [‘fmt’] )
The TO_NUMBER function converts the characters to a number format.
3)TO_DATE( char, [‘fmt’] )
The TO_DATE function converts the characters to a date data type.
— TO_CHAR() fmYYYY YYYY/MM/DD
SELECT TO_CHAR(SYSDATE, ‘YYYY/MM/DD’) FROM DUAL; — SO USING TO_CHAR U CAN GET FORMATE OF DATE ACCORDING TO UR REQURMENTS
—- $99,999 99.99 99,00
SELECT TO_CHAR(487, ‘$99,0’) FROM DUAL; — U CAN GET DATA IN CURRENCY FORMAT
—- TO_NUMBER()
SELECT TO_NUMBER(‘1745′,’99999’) FROM DUAL;
SELECT TO_NUMBER(‘1,47,982′,’9,99,999′) FROM DUAL;
—- TO_DATE() — THIS CONVERT VARCHAR DATE TO PROPER DATE FORMAT
SELECT TO_DATE(’30-JAN-1995′,’DD-MON-RRRR’) FROM DUAL;

In this video I use the COUNT and SUM functions available to the SQL language. I used the COUNT function to add up the number of records in my query. This function works well with all data types and will just count the number or records that result from the conditions of your query. The SUM function will add up the numeric values and produce a total amount of a column. When using a function be sure to use parenthesis around the column you are performing the function on.

This video we are going to discuss the NUMBER data type. The Number data type is used to store integers, and real numbers. When you create a column as a NUMBER, you can store pretty huge or pretty small numbers in this column. Now there are two things you need to consider when working with numbers, and that is the precision as well as the how big the number is.
For example, we can store the number 9.9. This has two significant digits. We could also store the number 9.9 X 10^4. In this situation, the number is much larger, but the number of significant digits is the same. 9.9 are the significant digits. When we expand this out we just have 99000, and the zeros are just used for size and are not considered "significant" in this situation. In fact, you get a max precision of 38, but a maximum value of 9.99 * 10^125. You can also use this data type to store very small numbers. Check the docs for the specifics on maximums and minimums.
You can provide it with two pieces of information:
Precision - The total number of digits.
Scale - The number of digits to the right of the decimal.
You do it in this format: NUMBER (precision, scale).
The important thing to remember in this is that when you specify a precision, you will be limiting the max size of the numbers.
The secret behind this data type is that it is actually stored in scientific notation. That is we store a number and then we can multiply it by 10 raised to some power. This allows us to store much larger numbers without taking up a ton of space.
The oracle docs actually gives a formula that you can use to see how much storage is going to be required for a specific NUMBER data type.
How much precision can be used? The acceptable range is 1-38.
What about scale? The range is actually -84 to 127. I'll explain the scale in more detail in an upcoming video. That's because there is a lot of confusing things here…What does it mean for the scale to be negative? How can we have a scale that is bigger that the total number of digits available through the precision. That's a topic for another video.
It's important to understand that when we increase our scale, we decrease the max size of the number. For example if we have a precision of 5 and a scale of 3, the highest number we can store is 99.999. This is in contrast to a precision of 5 and a scale of 2 which allows for up to 99.999. Either way you get 5 significant digits, but the numbers of digits to the left and right of the decimal change.

This is Manish from The Code makers
============================================
in this oracle database tutorial we will see what are SQL FUNCTIONS.
SQL functions are divided into two categories
1st is Single Row Functions
And another one is
Multiple row function which is also known as aggregate functions.
But in today's SQL tutorial we will concentrate on Single Row Functions.
Single-row functions operate on one row at a time and return one row of output for each input row.
Single row functions are capable of manipulating data items and modifying the data types.
Single row functions return one result per row and act on each row that is returned.
Single row functions can accept one or more arguments and return one value.
These arguments can be a column or an expression.
With oracle we have 5 types of Single Row Functions
1. Character Functions
2. Number Functions
3. General Functions
4. Conversion Functions and
5. Date Functions.
Character Functions are further divided into two categories.
1st is Case- manipulation functions
and
2nd is Character Manipulation functions.
We have 3 case manipulation functions Lower, upper and initcap
and 7 character manipulation functions Sql functions concat, substr, length, instr, lpad, rpad, trim and replace.
In our future video we will see what these functions are and what they do along with other SQL function.
That's it for today's sql tutorial. Hope you enjoyed watching.

Have a good day.

https://www.databasestar.com/oracle-remainder-mod/
The Oracle MOD function performs a “modulo division” on the numbers you specify. A modulo division is where a division is performed using two numbers, and the remainder is returned by the function.
For example, the division of 8/5 is 1.6. Using modulo division, 8/5 will work out there is one 5 contained in the 8, with 3 left over. The MOD function would return 3 in this example.
The syntax of the MOD function is:
MOD(numerator, denominator)
The numerator is the number mentioned first in the division, or the one that is on top of the division sign. In a division such as 15/4, this would be the 15.
The denominator is the number mentioned second in the devision, or hte one that is on the bottom of the division sign. In a division such as 15/4, this would be the 4.
The parameters can be any numeric data type, and the return type depends on these parameters. This means MOD can return a whole number or a decimal number.
The calculation for the Oracle MOD function is: numerator - denominator * FLOOR(numerator / denominator).
If the denominator is 0, the function returns the value of the numerator. This is done to prevent “divide by 0” errors.
For more information about the MOD function, including how to return every second row, how it’s different to REMAINDER, and to see the SQL code used in these examples, read the related article here:

This video is the 5th video in the series of 'working with null', this video explains the working of the lnnvl function in oracle sql with simple and easy to understand example.
LNNVL provides a concise way to evaluate a condition when one or both operands of the condition may be null. The function can be used only in the WHERE clause of a query.
It takes as an argument a condition and returns TRUE if the condition is FALSE or UNKNOWN and FALSE if the condition is TRUE.
LNNVL can be used anywhere a scalar expression can appear, even in contexts where the IS [NOT] NULL, AND, or OR conditions are not valid but would otherwise be required to account for potential nulls. Oracle Database sometimes uses the LNNVL function internally in this way to rewrite NOT IN conditions as NOT EXISTS conditions.
In such cases, output from EXPLAIN PLAN shows this operation in the plan table output. The condition can evaluate any scalar values but cannot be a compound condition containing AND, OR, or BETWEEN.

The Oracle EXP function returns the mathematical value of e raised to the nth power. EXP is short for “exponential”.
The value of “e” is a mathematical constant, and it’s roughly equal to 2.71.
The syntax of the EXP function is:
EXP( number )
We don't need to specify the value of e, because it's a standard value (kind of like pi).
The parameter for EXP is a number which represents the power to raise e to. For example, if the number is 2, then the function calculates e to the power of 2 and returns that number.

The Oracle CEIL function, short for “ceiling”, will return the smallest integer value greater than the specified number. In other words, it rounds up to the nearest whole number.
It’s the opposite of the FLOOR function, which rounds down.
The syntax of CEIL is:
CEIL(number)
The number parameter can be any numeric data type. The CEIL function will return a number in the same data type as the parameter.
So, you can use CEIL with decimal numbers, which is actually where CEIL works best. You can use it with whole numbers too. It won’t show an error, it just might display the same value as provided (e.g. CEIL(8) would be 8).
You can also use functions inside CEIL. For example, CEIL(SUM(salary)) will SUM all of the salary values, and then round them up to the nearest whole number.
Like with all functions, the Oracle CEIL function can also use column aliases. So, instead of having your column labelled “CEIL(8.12)” or “CEIL(salary)”, you can label your column “salary_rounded” or something that makes more sense.
The CEIL function is similar to the ROUND function. However, ROUND will round up or down, where CEIL will always round up. The TRUNC function will also do some kind of rounding, but it removes decimals from a number which may cause it to “round” down.

This video is the 4th video in the series of 'working with null', this video explains the working of the coalesce function in oracle sql. Also the video explains the use of coalesce function in oracle sql queries by perfect simple and easy to understand examples.
COALESCE returns the first non-null expr in the expression list. You must specify at least two expressions. If all occurrences of expr evaluate to null, then the function returns null.
Oracle Database uses short-circuit evaluation. The database evaluates each expr value and determines whether it is NULL, rather than evaluating all of the expr values before determining whether any of them is NULL.
If all occurrences of expr are numeric datatype or any non numeric datatype that can be implicitly converted to a numeric datatype, then Oracle Database determines the argument with the highest numeric precedence, implicitly converts the remaining arguments to that datatype, and returns that datatype.

https://www.databasestar.com/oracle-length/
The Oracle LENGTH function allows you to find the length of a string, also known as the number of characters in a string.
It’s a common feature in different languages, and SQL is no different.
The LENGTH function only has one parameter:
LENGTH ( string_value )
The parameter is the string_value which is the value to check the length of. The function returns a number that represents the number of characters in the function.
Some points to remember about the Oracle LENGTH function:
If string_value is NULL, then LENGTH will return NULL.
If string_value is an empty string, the LENGTH will return NULL.
The string_value can be any of the character data types - CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, NCLOB.
If the string_value is a CHAR data type, then the LENGTH will include any trailing spaces in the value.

https://www.databasestar.com/oracle-replace/
The Oracle REPLACE function is a string manipulation function that allows you to replace one text string with another. It can be a whole word or sentence, or even a single value.
The syntax of the REPLACE function is:
REPLACE ( whole_string, string_to_replace, [replacement_string])
To use this function, the parameters are:
- whole_string (mandatory): This is the string that will be checked for the characters to be replaced.
- string_to_replace (mandatory): This is the string that will be searched for within whole_string.
- replacement_string (optional): This is the string that will be used to replace occurrences of string_to_replace.
Because the last parameter is optional, if it is not specified, then the Oracle REPLACE function removes all occurrences of string_to_replace.
You can replace carriage returns with REPLACE, but you’ll need to use the CHR function.
You can replace NULL values in Oracle, but this is best done with another function such as NVL, rather than REPLACE.
If you want to replace multiple characters, you can do this using nested REPLACE functions or a REGEXP_REPLACE function.
For more information about the Oracle REPLACE function, including all of the SQL shown in this video and the examples, read the related article here:

The Oracle CHR function allows users to provide a numeric code and return the ASCII character that matches the code.
It’s the opposite of the ASCII function, which allows you to provide a character and return the code for that character.
The syntax of the CHR function is:
CHR(number_code [, USING NCHAR_CS])
The number code parameter is the code that you want to return the equivalent character for.
The USING NCHAR_CS keyword means that the national character set will be used. More information on character sets can be found here:
One common use of the CHR function is CHR(10). The number 10 is the line feed character, or “new line”, and is often used to start a new line of text.
CHR(13) is also a common use, which is a carriage return. CHR(9) is a tab character.

ADD_MONTHS():
The Oracle/PLSQL ADD_MONTHS function returns a date plus n months.
Syntax:
ADD_MONTHS( date1, n )
Arguments:
date1 is the starting date (before the n months have been added).
n is the number of months to add to date1.
Example:
Let's look at some Oracle ADD_MONTHS function examples and explore how you would use the ADD_MONTHS function in Oracle/PLSQL.
ADD_MONTHS('01-Aug-03', 3) would return '01-Nov-03'
ADD_MONTHS('01-Aug-03', -3) would return '01-May-03'
ADD_MONTHS('21-Aug-03', -3) would return '21-May-03'
ADD_MONTHS('31-Jan-03', 1) would return '28-Feb-03'
Thanks for watching..:)

https://www.databasestar.com/oracle-to_date/
The Oracle TO_DATE function is one of the most useful conversion functions in Oracle. It can be a little confusing though.
The TO_DATE function is used to convert a character value to a date value.
You can use it to convert a string that is in the format of a date, into a date data type.
Why would you use this?
Converting a character to a date is helpful if you want to insert a date into a column in a table. Being specific about the format (explicit) is better than assuming the conversion will be done for you (implicit).
This TO_DATE function only converts to a DATE data type. If you want to convert to the other datetime data types, you’ll have to use other functions such as TO_TIMESTAMP or TO_TIMESTAMP_TZ.
The syntax for this function is:
TO_DATE(charvalue [, format_mask [, nls_date_language]])
The parameters for this function are:
Charvalue: This is the character value that you want to convert to a date. It’s the main input of the function.
Format_mask: This is the format that the input value, the charvalue, is in. This is used to help convert your character value into a date, as your character may be in a different format to the default.
Nls_date_language: this is used to determine how the output is displayed.

In this video we will learn how to get decimal/float output from Integer division in SQL Server.
I am creating this video to answer once of the question that I posted while back for TSQL Interview Question list
"If I run Select 100/11 what output will I get?"
When you divide Integer by an Integer in SQL Server, SQL Server returns Integer output.
As we can see from our above example, SQL Server output is Integer for Integers division. If we want to get float or Decimal output, Either our denominator or Numerator should be float or decimal type.
If we have both denominator or numerator as Integers, we can use convert or cast functions to convert one of them to float/decimal so we can get our results as float/decimal.
There are multiple techniques you can use to convert/cast to integer to float/decimal, here are some examples
SELECT CAST(100 AS FLOAT) /11 AS OutputResult
SELECT 100/CAST(11 AS FLOAT) AS OutputResult
SELECT 100/CAST(11 AS DECIMAL(12,0)) AS OutputResult
SELECT CAST(100 AS DECIMAL(12,0))/11 AS OutputResult

The Oracle COVAR_SAMP function calculates the covariance of a set of number pairs.
If you know what a covariance is, then this function would be useful to you. I haven’t used it a lot though.
This function is similar to the COVAR_POP and CORR functions, and it can also be used as an aggregate or analytic function.
The syntax of the COVAR_SAMP function is:
COVAR_SAMP ( expression1, expression2 )
If using it as an aggregate function, the parameters of the COVAR_SAMP function are:
- expression1 (mandatory): The first set of numbers to use in the calculation.
- expression2 (mandatory): The second set of numbers to use in the calculation.
These parameters are numeric data types, and the return value is the same as the parameters.
If you use COVAR_SAMP as an analytic function, the syntax is:
COVAR_SAMP (expression1, expression2) OVER (analytic_clause)
The analytic_clause is added here, which is common for analytic queries.
For more information about the Oracle COVAR_SAMP function, including all of the SQL shown in this video and the examples, read the related article here:

https://www.databasestar.com/oracle-lpad/
The Oracle RPAD function is used to add extra characters to the right of a text value. This is called “padding”, and the function is called RPAD because the R stands for “right” and it “right pads” a text value.
It’s the opposite of LPAD, which pads characters to the left of the value.
The RPAD function can be useful for ensuring all values are the same length, or if there is another requirement you have for adding characters to the end.
The syntax is:
RPAD(expr, length [,pad_expression])
The expr parameter is the text value you want to pad or add characters to.
The length is the total length the expression or value will be after the padding has been done. It’s not the number of characters to add.
The pad_expression is an optional field and is the character or characters to add to the right end of the string. The default value is a space.
If the length specified in the function is shorter than the length of the string, then the string is truncated to meet the length.
For more information about the Oracle RPAD (and LPAD) function, including all of the SQL shown in this video and the examples, read the related article here:
