Create a stored procedure under Mysql command line

the SQL that establishes the stored procedure is as follows:

CREATE PROCEDURE proc_variable () BEGIN DECLARE dec_var_ VARCHAR (+); DECLARE rep_num INT; DECLARE Dec_var CURSOR for SELECT id_ from act_ru_variable WHERE name_ = ' yjdqsj ' GROUP by Execution_id_ have Coun T (name_) >1; OPEN Dec_var; REPEAT FETCH Dec_var into Dec_var_; DELETE from act_ru_variable WHERE id_ = dec_var_; UNTIL rep_num END REPEAT; CLOSE Dec_var; end;

If the above statement is executed directly, it encounters the first '; ' It's over, and then all the rest will get an error. The reason is that the default MySQL command terminator is a semicolon and requires a modified terminator to execute.
