Question

ALTER TABLE aspnet_Paths ALTER PathId SET DEFAULT UUID();

I’ve ran a converter program on “generate” scripts from a SQL Server database.
I seem to be having uuid in the above statement highlighted in work benches query window with the statement “Error Syntax near uuid()”,

I’m moving to MySQL. What’s the correct implementation of this statement?

Any help/advise is much appreciated

Try to use a BEFORE INSERT trigger –

DELIMITER $$

CREATE TRIGGER trigger1
BEFORE INSERT
ON aspnet_paths
FOR EACH ROW
BEGIN
  IF NEW.PathId IS NULL THEN
    SET NEW.PathId = UUID();
  END IF;
END
$$

DELIMITER ;
