当没有空值时,我的插入和更新存储过程正在工作,但是当我需要使某些列真的为空值时呢?
我在vb.net 2003中使用SQL Server存储过程
有关代码示例的任何建议
答案 0 :(得分:3)
您可以使用DBNull.Value
作为存储过程的参数。确保您的表允许字段为空值。
例如,如果您希望OE_Brand
为null
,则可以执行以下操作:
cmd.Parameters("@OE_Brand").Value = DBNull.Value
答案 1 :(得分:3)
将其设置为Nothing
将取消参数。请改用DBNull.Value
:
cmd.Parameters("@OE_Remarks").Value = DBNull.Value
