CRC32

Syntax

CRC32(expr)

Purpose

CRC32() calculates the cyclic redundancy check (CRC) value and returns a 32-bit unsigned value.

The expr argument should be a string, and if it is not a string, it may be considered a string.

If the argument is NULL, NULL is returned.

Examples

obclient>SELECT CRC32('hello-world');
+-----------------------+
|   COS32('hello-world')|
+-----------------------+
|             2983461467|
