delimiter $$
create procedure test()
BEGIN
declare wordpress_db varchar(100);
DECLARE wordpress_cursor_done INTEGER DEFAULT 0;
DECLARE wp_users_done INTEGER DEFAULT 0;


DECLARE wordpress_cursor CURSOR FOR
select SCHEMA_NAME from information_schema.schemata where SCHEMA_NAME like '%wordpress%';

DECLARE CONTINUE HANDLER FOR NOT FOUND SET wordpress_cursor_done = 1;

IF NOT EXISTS(select SCHEMA_NAME from information_schema.schemata where SCHEMA_NAME like '%wordpress%') THEN
SIGNAL SQLSTATE '99999' SET MESSAGE_TEXT = 'No database named wordpress';
END IF;


OPEN wordpress_cursor;
wordpress_cursor_loop:LOOP
FETCH wordpress_cursor INTO wordpress_db;
IF wordpress_cursor_done = 1 THEN
LEAVE wordpress_cursor_loop;
END IF;
IF NOT EXISTS(select table_name from information_schema.tables where table_schema = wordpress_db and table_name like '%wp_users%') THEN
SIGNAL SQLSTATE '99999' SET MESSAGE_TEXT = 'No table name wp_users';
else
set @get_id = concat('SELECT * FROM', wordpress_db , '.' , 'wp_users');
prepare stmt from @getid;
execute stmt;
deallocate prepare stmt;
END IF;
END LOOP;

CLOSE wordpress_cursor;
END $$
