=============================
在mysql命令行调用:call Sf_StudentInfo( ‘048 ‘, ‘F20050510160659 ‘,2,1);
出错信息：
Error 1414 :
OUT or INOUT argument 4 for routine dbb.Sf_StudentInfo is not a variable or NEW
pseudo-variable in BEFORE trigger.
====================
请大家帮帮忙啊…………
call Sf_StudentInfo( ‘048 ‘, ‘F20050510160659 ‘, ‘2 ‘,@a);
select @a;
最后一个参数必须是一个变量。
call Sf_StudentInfo( ‘048 ‘, ‘F20050510160659 ‘,2,@a);
select @a;
最后一个参数必须是一个变量。
