  • 为啥里面加了一个if,外面这个参数就没有了,然后里面的if去掉,外面这个参数才能用${if((OA='1'),"select *       from newsoft_cs.oa_wt_temp tmpleft join newsoft_cs.oa_wt t on tmp.file_id = t.file_idwhere t.status in ('S','A','ST') and${if(len(zt) == 0,"","and t.status in ('" + zt + "')")}${if(len(dybh) == 0,"","and tmp.print_code in ('" + dybh + "')")}${if(len(sfz) == 0,"","and tmp.user_id in ('" + sfz + "')")}${if(len(khmc) == 0,"","and tmp.customer_name in ('" + khmc + "')")}${if(len(strxm) == 0,"","and tmp.user_name in ('" + strxm + "')")}${if(len(stime) == 0,"","and tmp.begin_time >= ('" + stime + "')")}${if(len(etime) == 0,"","and tmp.end_time < ('" + etime + "')")}","select * from newsoft_cs.oa_wt_view WHERE 1=1${if(len(zt) == 0,"","and t.status in ('" + zt + "')")}${if(len(dybh) == 0,"","and tmp.print_code in ('" + dybh + "')")}${if(len(sfz) == 0,"","and tmp.user_id in ('" + sfz + "')")}${if(len(khmc) == 0,"","and tmp.customer_name in ('" + khmc + "')")}${if(len(strxm) == 0,"","and tmp.user_name in ('" + strxm + "')")}${if(len(stime) == 0,"","and tmp.begin_time >= ('" + stime + "')")}${if(len(etime) == 0,"","and tmp.end_time < ('" + etime + "')")}")}
  • if(${OA}==0,select 1 from dump,select 0 from dump)怎么判断当参数选折1的时候,用第一个sql语句,否则用第二个,
