Thanks Steve

Subject: Re: sql rand function

Here is sql code lifted from stack overflow that uses rand( ) to generate a GUID like value. Looks pretty random to me.

select LEFT(TRANSLATE ( CHAR(BIGINT(RAND() * 10000000000 )),
'abcdef123456789', '1234567890' ),8)
CONCAT '-' CONCAT
LEFT(TRANSLATE ( CHAR(BIGINT(RAND() * 10000000000 )),
'abcdef123456789', '1234567890' ),4)
CONCAT '-' CONCAT
LEFT(TRANSLATE ( CHAR(BIGINT(RAND() * 10000000000 )),
'abcdef123456789', '1234567890' ),4)
CONCAT '-' CONCAT
LEFT(TRANSLATE ( CHAR(BIGINT(RAND() * 10000000000 )),
'abcdef123456789', '1234567890' ),4)
CONCAT '-' CONCAT
LEFT(TRANSLATE ( CHAR(BIGINT(RAND() * 10000000000000 )),
'abcdef123456789', '1234567890' ),12)
