把代码贴上来
假如赋值字符串
string ls_result
select clo_result into :ls_result from table_name where id =:id;
if sqlca.sqlcode = -1 then
//错误
elseif sqlca.sqlcode = 100 then
//没有找到
else
//正确
end if
这样 ls_result里面有结果
select a.TID,b.SName as name1,c.SName as name2,d.SName as name3 from stuTest a inner join stuName b on a.name1=b.SID inner join stuName c on a.name2=c.SID inner join stuName d on a.name3=d.SID以上，希望对你有所帮助！
