Using RAND for Multiple Rows
Posted by: Steve K

I want to use RAND to update certain values in the database. I want to do something like this,

UPDATE table SET value = IF(@RAND_VALUE=RAND() < 0.1, 0,
@RAND_VALUE < 0.2, 1,
@RAND_VALUE < 0.3, 2, 3);

The problem I am having is that I need a unique value for every row in the table and embed the assignment in the SQL statement.

Any suggestions?
