    Is an expression of character or binary data. character_expression can be a constant, variable, or column. character_expression must be of a data type, except text, ntext, and image, that is implicitly convertible to varchar. Otherwise, use CAST to explicitly convert character_expression.

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.
