How to get the position of a character from a word in SQL server.

For this there is a function call CHARINDEX(). This is very similar to InStr function of VB.NET and IndexOf in Java. This function returns the position of the first occurrence of the first argument in the record.

SELECT CHARINDEX('r','server')

This would return 3 as it is start from 1.

SQL SERVER – TRIM() Function – UDF TRIM()

SQL Server does not have Trim() function. So we can create a own UDF (User Defined Function) function for this since SQL Sever does LTRIM(),RTRIM() functions and we can use this any time.
