LTRIM function (ODBC compatible)

Syntax

LTRIM ( char_expression [ , char_set ] )

Description

The scalar function LTRIM removes all the leading characters in char_expression, that are present in char_set and returns the resultant string. Thus, the first character in the result is guaranteed to be not in char_set. If the char_set argument is omitted, the function removes the leading and trailing blanks from char_expression.

Example

SELECT name, LTRIM (addr, ' ')

FROM customer ;

Notes

• The first and second arguments to the function must be of character type.
• If one of the arguments is a literal and the other one a field reference, the operation is possible only if the literal is convertible to the character set of the field reference. Otherwise an error is returned.
• The result is of character type whose character set is same as that of the arguments.
• If the argument expression evaluates to null, the result is null.
