In this post, I am providing one function to split string by using different type of delimiters and position in MySQL.

I have created this function because splitting a string is a very common requirement for all MySQL Database Developer.

I have created this function in such a way that you guys can pass any type of delimiter and split your string, but you also require to pass position to get exact value.

I have also created a similar kind of split function for SQL Server.
You can visit this article here:

For example, we have one column EmployeeName and it contains both Firstname and Lastname which is sperated by space. I require to create two column EmployeeFirstName and EmployeeLastName.

Below is a function and full demonstration of this:

First, Create a user defined function:

CREATE FUNCTION SplitString_ByAnyDelimiter
(
  InputString TEXT,
  InputDelimiter VARCHAR(8),
  InputPosition INT
)
RETURNS TEXT
RETURN 
REPLACE(SUBSTRING(SUBSTRING_INDEX(InputString, InputDelimiter, InputPosition),
       LENGTH(SUBSTRING_INDEX(InputString, InputDelimiter, InputPosition -1)) + 1),
       InputDelimiter, '');

Sample Executions:

SELECT SplitString_ByAnyDelimiter('Anvesh Patel', ' ', 1) AS FirstName

/* Result: 
FirstName
-----------
Anvesh
*/

SELECT SplitString_ByAnyDelimiter('Anvesh.Patel', '.', 2) AS LastName

/* Result: 
LastName
-----------
Patel
*/

SELECT SplitString_ByAnyDelimiter('Anvesh|Patel', '|', 1) AS FirstName

/* Result: 
FirstName
-----------
Anvesh
*/
