------解决思路----------------------
select @str=id from ui_application where package=old.pgn limit 1;->
select id into @str from ui_application where package=old.pgn limit 1;
------解决思路----------------------
select @str=id from ui_application where package=old.pgn limit 1;

select @str:=id from ui_application where package=old.pgn limit 1;
