【问题描述】:
SQL 无法识别我在主 SELECT 语句中调用的变量。我调用的变量是execs.block_order_quantity。我在查询开头的WITH 语句中命名了这个变量。代码如下,错误附在图片中。我已经运行了没有WITH execs as( 部分的select 语句,它工作得很好。
WITH execs as(SELECT th.exec_id, SUM(eha.tck_ord_qty) as "BLOCK_ORDER_QUANTITY"
FROM t1 eha
join t2 th
on eha.exec_id = th.exec_id
where th.trdng_desk_sname IN ('NAME')
and th.trd_dt between to_date('201840101', 'YYYYMMDD')
and to_date ('20140301', 'YYYYMMDD')
and exists
(SELECT 1
FROM t2t eth
WHERE eth.TRD_ID = eha.TRD_ID
AND eth.trd_stat_cd = 'EX')
group by th.exec_id)
SELECT DISTINCT
th.trd_dt as "TRADE_DATE",
eah.ord_cap_qty as "CAP_AMOUNT",
execs.block_order_quantity as "BLOCK_ORDER_QUANTITY",
eah.alloc_ovrrd_rsn_cd as "ALLOC_OVRRD_RSN_CD",

【问题讨论】:
-
你必须引用下面
from子句中的公用表表达式select -
@Damien_The_Unbeliever -- from 子句中的公用表表达式是什么意思?通过将其加入某事?
-
@IzzyFischer - 公用表表达式 (CTE) 是
WITH子句。您的主要查询引用了execs.block_order_quantity,但您没有在from/join子句中包含ececs。您需要指定该联接应如何工作。你确定你真的想要那个 CTE - 它似乎在重复主查询的部分,所以也许你真的想要一个分析总和?
