在 SSMS 2014 中,我有一个有效的 SELECT 查询,并希望将其转换为 UPDATE 语句以更新主表中的字段。我已经尝试并尝试了许多解决方案,每个解决方案都会导致不同的错误。
我之前已经设法进行简单的 UPDATE SET WHERE 查询,但是在 WHERE 子句中使用派生表会稍微复杂一些。在搜索时,我找到了一个 JOIN 解决方案,但对我来说,它不喜欢 RIGHT 或 JOIN,在那个解决方案中,SET 是最后一行,SSMS 也不喜欢这样,所以我现在有点困惑。
这是我选择正确 SKU 的工作 SELECT 语句:
SELECT
dbo.tblHKProducts.SKU_ID, dbo.tblHKProducts.SKU_Description,
dbo.tblHKProducts.SKU_Scan_Group
FROM
dbo.tblHKProducts
RIGHT OUTER JOIN
(SELECT
tblHKProducts_1.SKU_ID, tblHKProducts_1.SKU_Description,
dbo.ForceScanByDescriptions.FindDescription
FROM
dbo.tblHKProducts AS tblHKProducts_1
RIGHT OUTER JOIN
dbo.ForceScanByDescriptions ON tblHKProducts_1.SKU_Description = dbo.ForceScanByDescriptions.FindDescription
WHERE
(tblHKProducts_1.SKU_Description IS NOT NULL)
) AS derivedtbl_1 ON dbo.tblHKProducts.SKU_ID = derivedtbl_1.SKU_ID
我正在尝试做这样的事情,SKU_Scan_Group 是一个字段tblHKProducts
:
UPDATE dbo.tblHKProducts
SET SKU_Scan_Group = N'Yes'
RIGHT OUTER JOIN
(SELECT
tblHKProducts_1.SKU_ID, tblHKProducts_1.SKU_Description,
dbo.ForceScanByDescriptions.FindDescription
FROM
dbo.tblHKProducts AS tblHKProducts_1
RIGHT OUTER JOIN
dbo.ForceScanByDescriptions ON tblHKProducts_1.SKU_Description = dbo.ForceScanByDescriptions.FindDescription
WHERE
(tblHKProducts_1.SKU_Description IS NOT NULL)
) AS derivedtbl_1 ON dbo.tblHKProducts.SKU_ID = derivedtbl_1.SKU_ID
任何帮助,将不胜感激!
