=if(len(sql("FLDSYS","select FID from rota_manage where to_char( rota_data,'yyyy-mm-dd')='"+C5+"'",1,1))==0,sql("FLDSYS","select max(FID) from rota_manage ",1,1)+row(),sql("FLDSYS","select FID from rota_manage where to_char( rota_data,'yyyy-mm-dd')='"+C5+"'",1,1)，请各位帮忙看一下这个语句有什么不对呢。或是需要在条件属性中写什么呢才能实习这语句的功能？
主要是+row()这个
