对 SQL Server 的 MS Access 查询

Question

Sql 服务器没有像 MS Access 那样的 First() 函数。 那么我将如何将此查询转换为在 sql server 中工作

SELECT 
First([MyTable].Col1) AS Col1, 
First([MyTable].Col2) As Col2, 
First([MyTable].Col3) As Col3,
First([MyTable].Col4) As Col4,
First([MyTable].Col5) As Col5,
First([MyTable].Col6) AS Col6, 
[MyTable].Col7 INTO [MyTable2]
FROM [MyTable]
WHERE ((([MyTable].OtherCol1)='S') AND (([MyTable].OtherCol2) Is Null))
GROUP BY [MyTable].Col7
HAVING ((([MyTable].Col7) Is Not Null Or ([MyTable].Col7)<>' '));

Answer 1

SELECT 
min([MyTable].Col1) AS Col1, 
min([MyTable].Col2) As Col2, 
min([MyTable].Col3) As Col3,
min([MyTable].Col4) As Col4,
min([MyTable].Col5) As Col5,
min([MyTable].Col6) AS Col6, 
[MyTable].Col7 
INTO [MyTable2]
FROM [MyTable]
WHERE ((([MyTable].OtherCol1)='S') AND (([MyTable].OtherCol2) Is Null))
GROUP BY [MyTable].Col7
HAVING ((([MyTable].Col7) Is Not Null Or ([MyTable].Col7)<>' '));
