sql - Workflow control in mysql or oracle -

-

in mssql, can submit batch query statements workflow control, this:

declare @num int select @num = 100 if @num > 0 begin select @num = @num + 1 end

how in mysql or oracle (without procedure or function).

you can't use if ... then in official mysql outside of stored programs.

you can, however, in mysql-compatible mariadb, starting in version 10.1 (currently in beta).

now 1 can use begin, if, case, while, loop, repeat statements directly in sql scripts , mysql command line prompt — outside of stored programs.
