Return Type

Remarks

Compatibility levels can affect return values. For more information about compatibility levels, see sp_dbcmptlevel (Transact-SQL).

Examples

The following example uses LTRIM to remove leading spaces from a character variable.

DECLARE @string_to_trim varchar(60)
SET @string_to_trim = '     Five spaces are at the beginning of this
   string.'
SELECT 'Here is the string without the leading spaces: ' + 
   LTRIM(@string_to_trim)
GO

Here is the result set.
