等效IFF的

Question

我试图访问IFF查询转换为SQL Server查询

SELECT blah blah , 
    IIf([stock]![supplier]=[pos]![supplier],"Preferred"," ") AS Preferrednew 
FROM blah blah 

在访问这会给在一个名为Preferrednew列首选一个值，条件为真。

我已经转换代码..

SELECT blah blah , 
CASE WHEN ([stock.supplier] = [pos.supplier]), 'test', 'test2' AS [preferrednew] 
FROM blah blah 

，但我得到的错误

附近有语法错误 ''

什么是正确的格式？

Answer 1

SELECT blah blah , 
    CASE WHEN stock.supplier = pos.supplier THEN 'test' 
    ELSE 'test2' 
    END AS [preferrednew] 
FROM blah blah 

请记住，SQL服务器2012+支持IIF
