我正在尝试将2个查询组合到sql-server传递查询(PTQ)。在Access中单独编码时,两个查询都有效。将这些访问代码组合到一个查询时,它仍然可以在Access中使用。 但是当我将字段名称格式化为T-sql并尝试作为PTQ运行时,我在“GROUP”附近出现语法错误。当我删除这个“GROUP BY”行时,我在“;”附近收到语法错误。
SELECT jaar,
maand,
wicode,
pg_intern_code,
pg_kriss_code,
pg_kriss_naam,
Count(pc0517.dbo.resul.klavnr) AS AantalVanKLAVNR
FROM (SELECT Year(pc0517.dbo.resul.created) AS JAAR,
Month(pc0517.dbo.resul.created) AS MAAND,
pc0517.dbo.resul.wicode,
dbo.tblproductgroep_intern.pg_intern_code,
dbo.tblproductgroep_kriss.pg_kriss_code,
dbo.tblproductgroep_kriss.pg_kriss_naam,
pc0517.dbo.resul.klavnr
FROM (dbo.tblproductgroep_kriss
INNER JOIN (dbo.tblproductgroep_intern
INNER JOIN dbo.tblrobbe_pg
ON dbo.tblproductgroep_intern.pg_intern_id =
dbo.tblrobbe_pg.pg_code_intern_id)
ON dbo.tblproductgroep_kriss.pg_kriss_id =
dbo.tblrobbe_pg.pg_code_kriss_id)
INNER JOIN pc0517.dbo.resul
ON dbo.tblrobbe_pg.robbe_pg_naam =
pc0517.dbo.resul.prcode
WHERE ( ( Year(pc0517.dbo.resul.created) = 2012 )
AND ( pc0517.dbo.resul.kanaal = "gg" ) ))
GROUP BY jaar,
maand,
wicode,
pg_intern_code,
pg_kriss_code,
pg_kriss_naam;
其他PTQ在同一个数据库中(甚至与PC0517数据库结合使用),工作没有任何故障,但我对SQL服务器完全不熟悉,所以我还不知道所有的约定,我可能会忽略一些东西基本...
TIA
答案 0 :(得分:2)
我纠正了各种各样的事情:(1)以正确的顺序放置连接(2)删除错位的括号(3)
为可读性添加了表别名(4)在"gg"
(5)周围删除了双引号,使得针对r.created的查询成为开放式范围,以便可以使用索引(如果存在)。我还从分组中的内部查询中删除了jaar
- 基于where子句,除了2012
之外,它永远不会是任何其他内容。
如果你将它粘贴到那里,我不知道Access会对此做什么,但你应该能够确认这是一个比通过直接对SQL Server运行的垃圾访问更正确的查询。如果Access仍然打破了这个,我会将它放在SQL Server中的存储过程或视图中,并指向Access。
SELECT
jaar = 2012,
maand,
wicode,
pg_intern_code,
pg_kriss_code,
pg_kriss_naam,
COUNT(klavnr) AS AantalVanKLAVNR
FROM
(
SELECT
maand = MONTH(r.created),
r.wicode,
i.pg_intern_code,
k.pg_kriss_code,
k.pg_kriss_naam,
r.klavnr
FROM
dbo.tblproductgroep_kriss AS k
INNER JOIN dbo.tblrobbe_pg AS tr
ON k.pg_kriss_id = tr.pg_code_kriss_id
INNER JOIN dbo.tblproductgroep_intern AS i
ON i.pg_intern_id = tr.pg_code_intern_id
INNER JOIN pc0517.dbo.resul AS r
ON tr.robbe_pg_naam = r.prcode
WHERE
r.created >= '20120101' AND r.created < '20130101'
AND r.kanaal = 'gg'
) AS x
GROUP BY
maand,
wicode,
pg_intern_code,
pg_kriss_code,
pg_kriss_naam;
它也可以简化为:
SELECT
jaar = 2012,
maand = MONTH(r.created),
r.wicode,
i.pg_intern_code,
k.pg_kriss_code,
k.pg_kriss_naam,
r.klavnr
FROM
dbo.tblproductgroep_kriss AS k
INNER JOIN dbo.tblrobbe_pg AS tr
ON k.pg_kriss_id = tr.pg_code_kriss_id
INNER JOIN dbo.tblproductgroep_intern AS i
ON i.pg_intern_id = tr.pg_code_intern_id
INNER JOIN pc0517.dbo.resul AS r
ON tr.robbe_pg_naam = r.prcode
WHERE
r.created >= '20120101' AND r.created < '20130101'
AND r.kanaal = 'gg'
GROUP BY
MONTH(r.created),
r.wicode,
i.pg_intern_code,
k.pg_kriss_code,
k.pg_kriss_naam;
(换句话说,子查询似乎没必要。)
