SQL update query syntax with inner join
提问by MAW74656
Can anyone find my error in this query? I'm using SQL Server 2000 and I want to update all entries in the CostEntry table to the corresponding value in the ActiveCostDetails table. The where clause DOES work with a select statement.
任何人都可以在此查询中找到我的错误吗？我正在使用 SQL Server 2000 并且我想将 CostEntry 表中的所有条目更新为 ActiveCostDetails 表中的相应值。where 子句确实适用于 select 语句。
UPDATE CostEntry CE
INNER JOIN ActiveCostDetails As AD ON CostEntry.lUniqueID = ActiveCostDetails.UniqueID
SET CostEntry.sJobNumber = ActiveCostDetails.JobNumber
WHERE CostEntry.SEmployeeCode = '002'
AND SubString(CostCentre, 1, 1) = sDepartmentCode
AND substring(CostCentre, 3, 1) = sCategoryCode
AND substring(CostCentre, 5, 2) = sOperationCode

The SETneeds to come before the FROM\JOIN\WHEREportion of the query.
的SET需求来对之前FROM\JOIN\WHERE查询的部分。
UPDATE CE
SET sJobNumber = AD.JobNumber
FROM CostEntry CE
INNER JOIN ActiveCostDetails As AD
ON CE.lUniqueID = AD.UniqueID
WHERE CE.SEmployeeCode = '002'
AND SubString(CostCentre, 1, 1) = sDepartmentCode
AND substring(CostCentre, 3, 1) = sCategoryCode
AND substring(CostCentre, 5, 2) = sOperationCode

This should work
这应该工作
UPDATE CE
SET CostEntry.sJobNumber = ActiveCostDetails.JobNumber
FROM CostEntry CE
INNER JOIN ActiveCostDetails As AD ON CostEntry.lUniqueID = ActiveCostDetails.UniqueID
WHERE CostEntry.SEmployeeCode = '002'
AND SubString(CostCentre, 1, 1) = sDepartmentCode
AND substring(CostCentre, 3, 1) = sCategoryCode
AND substring(CostCentre, 5, 2) = sOperationCode
