Question

当我尝试在存储过程中执行动态查询时，我收到错误。

我的代码是：

DECLARE @Query nvarchar(max)
DECLARE @AllowanceBadge nvarchar(20)
DECLARE @AllowFieldName nvarchar(50)
DECLARE @Amount Decimal
SET @AllowanceBadge  ='SIP0980'
SET @AllowFieldName ='xxxxx'
SET @Amount = 100

SET @Query = 'UPDATE tbl_PayrollTransaction SET '+ @AllowFieldName +' = '+convert(varchar,@Amount) + 'WHERE BadgeNumber = '+@AllowanceBadge
            EXEC SP_EXECUTESQL @Query

我收到了以下错误

Msg 207，Level 16，State 1，Line 1
列名称'SIP0980'无效。

告诉我我哪里错了。

SIP0890需要引用

DECLARE @Query nvarchar(max)
DECLARE @AllowanceBadge nvarchar(20)
DECLARE @AllowFieldName nvarchar(50)
DECLARE @Amount Decimal
SET @AllowanceBadge  ='SIP0980'
SET @AllowFieldName ='xxxxx'
SET @Amount = 100

SET @Query = 'UPDATE tbl_PayrollTransaction SET '+ @AllowFieldName +' = '+convert(varchar,@Amount) + 'WHERE BadgeNumber = '''+@AllowanceBadge+''''
            EXEC SP_EXECUTESQL @Query

使用sp_executesql时列名无效
