大佬们,我的公式如下:select OT.FName as OT_FName,U.FName as U_FName,U.FForbidden as U_FForbidden,OAT.FName as OAT_FName,OAT.FDescription as OAT_FDescriptionfrom t_ObjectType OTjoin t_AccessControl AC on AC.FObjectID = OT.FObjectID and AC.FObjectType = OT.FObjectTypejoin t_ObjectAccessType OAT on OAT.FObjectID = AC.FObjectID and OAT.FObjectType = AC.FObjectType join t_User U on AC.FUserID = U.FUserIDwhere 1 = 1${if(len(treeComboBoxEditor0t_ObjectType)==0,"","AND OT.FObjectType ='"+${layer1}+"'AND OT.FObjectID ='"+${layer2}+"'")}${if(len(comboBox1_t_User)==0,"","AND U.FName ='"+comboBox1_t_User+"'")}order by U.FName;其中${if(len(treeComboBoxEditor0t_ObjectType)==0,"","AND OT.FObjectType ='"+${layer1}+"'AND OT.FObjectID ='"+${layer2}+"'")}是获取下拉树一级二级的值作为查询条件的,但是报错:错误代码:11300001 数据集 配置错误'$' 附近有语法错误想问下公式怎么改
