Question

I have created simple function

create function TRIM(@data varchar(20)) returns varchar(100)
as
begin
  declare @str varchar(20)
  set @str = rtrim(ltrim(@data))
  return @str
end

I am executing in the below way.

declare @s varchar(25)
set @s = '      Amru    '
select TRIM(@s)

I am getting the following error.

Msg 195, Level 15, State 10, Line 3
'TRIM' is not a recognized built-in function name.

Could any one please help me find the issue?

Answer 1

You need to use the Schema prefix when calling user defined functions. In your case this will most likely be “dbo”.

Change your select statement to:

declare @s varchar(25)
set @s = '      Amru    '
select dbo.TRIM(@s)
