Sys_MapAttr表中groupid为vchar20，Sys_GroupField 表中oid为int4
执行到
SELECT MyPK FROM Sys_MapAttr WHERE FK_MapData='" + this.No + "' AND GroupID NOT IN (SELECT OID) FROM Sys_GroupField WHERE FrmID='" + this.No + "' AND ( CtrlType='' OR CtrlType IS NULL) ) OR GroupID IS NULL
提示 operator does not exist: integer = character varying

后续安装好了，总是提示用户失效
