In sql-server there is function to auto-increment guid fields.
CREATEGUID()
how can I do the same thing in Mysql?
I’m new in database programing.
I want to create primary key field 16byte auto-incremented.
You can create a BEFORE INSERT trigger to check new value for the auto-increment guid field, and if it is NULL, set value = UUID().
This function may be useful too – UUID_SHORT().
UUID_SHORT() – Returns a “short” universal identifier as a 64-bit unsigned integer (rather than a string-form 128-bit identifier as returned by the UUID() function).
