--先打印出sql语句,然后直接执行你打印的语句看有无记录 set serveroutput on; declare V_CONDTION varchar2(1000):= '1,2,3,4';--换成你的值 v_str varchar2(4000):=''; begin v_str:= 'select a.s_txm,b.content from shuibiaoxx a inner join ( select * from words where belongid=''106'' ) b on a.s_ztid=b.wordsid where a.s_txm in('||V_CONDTION||')'; dbms_output.put_line(v_str); end; /
