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.
Here I have created a simple Function for this.

Create Function Trim(@mText  varchar(MAX))
Returns varchar(MAX)
AS
Begin
return LTRIM(RTRIM(@mText))
End

You can run this function as shown below here,

Select dbo.Trim(' Test  ')

So this function would return ‘Test’ only as LTRIM() function would cut off the Left side spaces and RTRIM() functiom would cut off the Right side spaces.
