我是甲骨文的新手。我有三张桌子。我想从 join tbl_ledger , tbl_ledger_input 插入表 tbl_ledger_branch 我的代码是：
BEGIN
for i in min(a.eff_date ).. max(a.eff_date) LOOP
insert into tbl_ledger_branch (ledger_code , name , depth , parent_code , balance , ref_cur_id , eff_date , ref_branch , cur_balance , number_date )
select a.ledger_code , max( b.name ) name , max(b.depth) depth ,
max(CONCAT(SUBSTR(b.LEDGER_CODE,1,9),'00')) PARENT_CODE , sum(a.balance) balance,
i eff_date, a.ref_branch , a.cur_balance
from tbl_ledger_input a inner join tbl_ledger b
on a.ledger_code = b.ledger_code
where eff_date <= i
group by a.ref_branch ,a.ref_cur_id ,a.ledger_code , a.cur_balance
END LOOP ;
END ;
但我得到错误：
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
请帮助我。
