SQL OPENQUERY，“+”附近的语法不正确

Question

我有这个 sql 查询：

DECLARE  @VAR varchar(8)
SET  @VAR = '20140202'
SELECT * FROM OPENQUERY([NMD],'SELECT * FROM NmdItemGroups01.dbo.InvTranDtl WHERE TranDate = ''' + @VAR + '''')

但是当我运行它时，它给出了这个错误：

Incorrect syntax near '+'

Answer 1

sp_executesql 示例：

DECLARE  @VAR varchar(8)
SET  @VAR = '20140202'

EXEC sp_executesql 
    N'SELECT * FROM NmdItemGroups01.dbo.InvTranDtl WHERE TranDate = @TranDate', 
    N'@TranDate DATE', 
    @VAR
