LTRIM

Syntax

Description of ltrim.gif follows
Description of the illustration ltrim.gif

Purpose

LTRIM removes from the left end of char all of the characters contained in set. If you do not specify set, then it defaults to a single blank. If char is a character literal, then you must enclose it in single quotation marks. Oracle Database begins scanning char from its first character and removes all characters that appear in set until reaching a character not in set and then returns the result.

Both char and set can be any of the data types CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB. The string returned is of VARCHAR2 data type if char is a character data type, NVARCHAR2 if char is a national character data type, and a LOB if char is a LOB data type.
