使用merge，报错信息是There is an incorrect syntax near the keyword 'into'

Question

我这样使用合并：

BEGIN TRANSACTION
    merge into TD_1 tar
    using (select Title,AnnouncementID,SupplyTitle,EmployeeCode,registered,modified from TSupply_2 ) source
    on (tar.SupplyTitle=source.SupplyTitle and tar.EmployeeCode=source.EmployeeCode) 
    when matched then update set tar.modified=getdate()
    when not matched then
    insert (Title,AnnouncementID,SupplyTitle,EmployeeCode,registered,modified) 
    values(source.Title,source.AnnouncementID,source.SupplyTitle,source.EmployeeCode,getdate(),getdate());
COMMIT TRANSACTION

但是错误是：

There is an incorrect syntax near the keyword 'into'.

There is an incorrect syntax near 'source'.

我该如何解决？

Answer 1

合并语法：

MERGE <target_table> [AS TARGET]
USING <table_source> [AS SOURCE]
ON <search_condition>
[WHEN MATCHED 
THEN <merge_matched> ]
[WHEN NOT MATCHED [BY TARGET]
THEN <merge_not_matched> ]
[WHEN NOT MATCHED BY SOURCE
THEN <merge_matched> ];

但是你正在使用 into:

merge into TD_1 tar

另外source是SQL的保留字。如果你愿意，你可以更换它。

试着看看这个tutorial。

Answer 2

现在我知道哪里错了，COMPATIBILITY_LEVEL在我的数据库中是80。所以我不能使用 merge.

我的数据库版本是Microsoft SQL Server 2008 然后我修改了COMPATIBILITY_LEVEL:

ALTER DATABASE DB1
SET COMPATIBILITY_LEVEL = 100

然后就没有报错了

使用merge，报错信息是There is an incorrect syntax near the keyword 'into'

Use merge,the error message is There is an incorrect syntax near the keyword 'into'
