【中文标题】错误（13,34）：PLS-00201：必须声明标识符“D.BNDNG_TYP”【英文标题】：Error(13,34): PLS-00201: identifier 'D.BNDNG_TYP' must be declared 【发布时间】：2020-06-26 13:58:56 【问题描述】：我写了一个程序，我试图将值从源表插入到目标表中，我使用批量收集来执行大量数据的数据。

在上述过程中，出于安全目的，我删除了一些列名。
我遇到两个错误，一个是
PLS-00201：必须声明标识符“D.BNDNG_TYP”和 PLS-00225：子程序或游标“cur3”引用超出范围
如果有人可以帮助解决这个问题。
【问题讨论】：
如果我没看错的话，会有一个';'在光标 cur1 声明的末尾缺少 与您关于此过程的其他帖子的 cmets 相同 - 格式、参数命名等：***.com/q/62600904/230471 【参考方案1】：在游标中，您不能提供从游标查询中引用别名的类型。您只需提供表名test1 而不是别名d。
CURSOR cur2( BND_TYPE test1.bndng_typ%TYPE,
BND_VAL test1.bndng_val%TYPE,
FINANCIAL_INST_ID test1.financial_institution_id%TYPE,
PRDCT_ID test1.prdct_id%TYPE,
PRDCT_SUB_ID test1.prdct_sub_id%TYPE,
INSTRUMENT_ID test1.instrmnt_id%TYPE)

【讨论】：
那么它怎么知道我们传入的参数的数据类型，我尝试删除它但它不起作用 谢谢，它现在可以工作了..你知道我们如何重写光标cur3，因为我收到上面提到的错误“子程序或光标'cur3'引用超出范围” 【参考方案2】：这是未经测试的，因为我没有你的表和数据，但作为第一次重构，我将从这种类型的结构开始：
create or replace procedure test2
as
cursor loan_data_cur
( bnd_type cr_loan_prima_rate_orig.bndng_typ%type
, bnd_val cr_loan_prima_rate_orig.bndng_val%type
, financial_inst_id cr_loan_prima_rate_orig.financial_institution_id%type
, prdct_id cr_loan_prima_rate_orig.prdct_id%type
, prdct_sub_id cr_loan_prima_rate_orig.prdct_sub_id%type
, instrument_id cr_loan_prima_rate_orig.instrmnt_id%type )
is
select d.*
from test1 d
join ( select b.prdct_id
from test2 a
join test1 b
on b.ir_id = a.ir_id
and b.price_component_id = a.price_component_id
and b.financial_institution_id = a.financial_institution_id
group by b.prdct_id ) e
on d.prdct_id = e.prdct_id
where d.bndng_typ = loan_data_cur.bnd_type
and d.bndng_val = loan_data_cur.bnd_val
and d.financial_institution_id = loan_data_cur.financial_inst_id
and d.prdct_id = loan_data_cur.prdct_id
and d.prdct_sub_id = loan_data_cur.prdct_sub_id
and d.instrmnt_id = loan_data_cur.instrument_id;
begin
for loan_data in (
select distinct *
from test
)
loop
for loan_rate in loan_data_cur
( loan_data.bndng_typ
, loan_data.bndng_val
, loan_data.financial_institution_id
, loan_data.prdct_id
, loan_data.prdct_sub_id
, loan_data.instrmnt_id )
loop
update test t set t.seq_num = 1
where t.seq_num = 2
and t.pos_num = loan_data.pos_num
and t.pos_type = loan_data.pos_type
and t.price_component_id = loan_rate.price_component_id
and t.rprtd_till_dt = loan_data.rprtd_till_dt;
if sql%rowcount = 0 then
insert into test values (x, y, z);
end if;
end loop;
end loop;
commit;
end test2;
我还会考虑将 test 到 test1 的连接视为单个游标，而不是显式使用两个单独的游标，因为优化器可能会找到更有效的方法，例如哈希连接。
可能update/insert 组合可以写成单个merge。一旦你有一个 merge 工作，你可能会发现你可以一次将它应用到整个表格，并且根本不需要任何光标循环。
如果逐行更新的数量导致性能问题（例如，如果它超过几千个），则将批量收集到数组中可能很有用。如果是这样，您需要对其进行结构化，以便您可以使用 forall 构造而不是更多循环来应用更新/插入。
