SUBSTR

Syntax

SUBSTR(<string>; <start number> [; <length>])

Description

Returns a specific number of characters from a text string starting at the position you specify. If no length is specified, the rest of the string is returned. The first value in a string has the start number of 0.

When a string value is evaluated by the function and no characters can be returned, the returned value is an empty string.

When a null value is evaluated by the function, the returned value is null.
