有这样一个SQLselect acccodj_0,acccodd_0 后面省略.............他的值是15 16
14 16
13 16我想在这个sql后再加一个字段,
如 select acccodj_0,acccodd_0 ,xxx
让他的值为15 16 (字段ACC_15的值)
14 16 (字段ACC_14的值)
13 16 (字段ACC_13的值)这个SQL该怎么写
14 16

select acccodj_0,acccodd_0 ,"字段ACC_" || acccodj_0 || "的值" as xxx
但是这么多的字段,那样写也太傻了
用case或decode实现,但是可以excel帮你完成。(我一般就是这么玩的)
sqlstr varchar(400);
begin
sqlstr :='select acccodj_0,acccodd_0';
for i in 1..99 loop
sqstr:=sqlstr||',ACC_'||i;
end loop
sqlstr:=sqlstr||'from table_test';
end ;
