Question

我已成功使用类似以下内容的查询但我不能使用'变量'进行更新我可以不使用它们。这可能吗？这抱怨了

'set stuf_rec.stat =“A”
附近的语法不正确

DECLARE @stuf_no varchar(6)
set @stuf_no = 267
DECLARE @sql varchar (2000) 
set @sql = 
'UPDATE OPENQUERY(train,''select stat from stuf_rec 
where stuf_no =  '+ @stuf_no + ''')'' set stuf_rec.stat = ' + '"A"' + ' 
where stuf_rec.stuf_no = ' + @stuf_no + ''';'

谢谢..

这适用于你吗？或者值是否必须有双引号？

DECLARE @stuf_no varchar(6)
set @stuf_no = '267'
DECLARE @sql varchar (2000)

set @sql =    
'UPDATE OPENQUERY(train,''select stat from stuf_rec    
where stuf_no =  '+ @stuf_no + ''') set stuf_rec.stat = ''A''     
where stuf_rec.stuf_no = ' + @stuf_no + ';'

@sql的结果如下所示：

UPDATE OPENQUERY(train,'select stat from stuf_rec      
                        where stuf_no =  267') 
    set stuf_rec.stat = 'A'       
    where stuf_rec.stuf_no = 267;

TSQL使用params更新openquery
