SELECT DISTINCT dbo.master_order.order_no,

INNER JOIN dbo.Setup_size ON dbo.transaction_order.size_id = dbo.Setup_size.size_id
INNER JOIN dbo.Setup_yarn ON dbo.transaction_order.yarn_id = dbo.Setup_yarn.yarn_id
INNER JOIN dbo.Setup_article_order ON dbo.transaction_order.article_id = dbo.Setup_article_order.article_id
INNER JOIN dbo.Setup_color ON dbo.transaction_order.color_id = dbo.Setup_color.color_id
AND dbo.Setup_yarn.color_id = dbo.Setup_color.color_id
WHERE dbo.setup_color.color_id=
    (SELECT color_no
     FROM dbo.setup_color) WHERE master_order.shipment_date>=@from
  AND master_order.shipment_date<=@to

Answer 1

这是你在WHERE子句之后的语法

   where dbo.setup_color.color_id=
   (select color_no from dbo.setup_color) 
    where master_order.shipment_date>=
   @from and master_order.shipment_date<=@to

主Query上有2个Where子句。

Answer 2

用于代替等于子查询。

SELECT DISTINCT 
dbo.master_order.order_no, 
dbo.master_order.program_no, 
dbo.Setup_size.size_name, 
dbo.Setup_color.color_name, 
dbo.Setup_color.color_no, 
dbo.transaction_production.total_weight, 
dbo.Setup_yarn.yarn_count, 
dbo.Setup_article_order.article_name, 
dbo.master_order.shipment_date, 
@from as reprt,
@to as reprt1, 
dbo.transaction_order.quantity, 
dbo.transaction_order.gsm 

FROM dbo.master_order 
INNER JOIN dbo.transaction_order ON dbo.master_order.order_id = dbo.transaction_order.order_id 
INNER JOIN dbo.transaction_production ON dbo.transaction_order.trans_id = dbo.transaction_production.trans_id 
INNER JOIN dbo.Setup_size ON dbo.transaction_order.size_id = dbo.Setup_size.size_id 
INNER JOIN dbo.Setup_yarn ON dbo.transaction_order.yarn_id = dbo.Setup_yarn.yarn_id 
INNER JOIN dbo.Setup_article_order ON dbo.transaction_order.article_id = dbo.Setup_article_order.article_id 
INNER JOIN dbo.Setup_color ON dbo.transaction_order.color_id = dbo.Setup_color.color_id
 AND dbo.Setup_yarn.color_id = dbo.Setup_color.color_id where dbo.setup_color.color_id in
 (select color_no from dbo.setup_color) where master_order.shipment_date >= @from and master_order.shipment_date<= @to

Answer 3

问题是你在主查询中有2个WHERE子句。由于master_order是主查询中使用的表，只需将WHERE替换为AND，如下所示。

SELECT DISTINCT dbo.master_order.order_no,
                dbo.master_order.program_no,
                dbo.Setup_size.size_name,
                dbo.Setup_color.color_name,
                dbo.Setup_color.color_no,
                dbo.transaction_production.total_weight,
                dbo.Setup_yarn.yarn_count,
                dbo.Setup_article_order.article_name,
                dbo.master_order.shipment_date,
                @from AS reprt,
                @to AS reprt1,
                dbo.transaction_order.quantity,
                dbo.transaction_order.gsm
FROM dbo.master_order
INNER JOIN dbo.transaction_order ON dbo.master_order.order_id = dbo.transaction_order.order_id
INNER JOIN dbo.transaction_production ON dbo.transaction_order.trans_id = dbo.transaction_production.trans_id
INNER JOIN dbo.Setup_size ON dbo.transaction_order.size_id = dbo.Setup_size.size_id
INNER JOIN dbo.Setup_yarn ON dbo.transaction_order.yarn_id = dbo.Setup_yarn.yarn_id
INNER JOIN dbo.Setup_article_order ON dbo.transaction_order.article_id = dbo.Setup_article_order.article_id
INNER JOIN dbo.Setup_color ON dbo.transaction_order.color_id = dbo.Setup_color.color_id
AND dbo.Setup_yarn.color_id = dbo.Setup_color.color_id
WHERE dbo.setup_color.color_id=
    (SELECT color_no
     FROM dbo.setup_color)
  AND master_order.shipment_date>=@from
  AND master_order.shipment_date<=@to

此外，如果表dbo.setup_color具有多于1的值，则使用IN而不是=或向内部查询添加WHERE子句以仅返回一个值，否则将抛出错误。
