LEFT function [String]

Returns a number of characters from the beginning of a string.


LEFT( string-expression, integer-expression )


string-expression    The string.

integer-expression    The number of characters to return.


If the string contains multibyte characters, and the proper collation is being used, the number of bytes returned may be greater than the specified number of characters.

You can specify an integer-expression that is larger than the value in the column. In this case, the entire value is returned.

Whenever possible, if the input string uses character length semantics the return value will be described in terms of character length semantics.
