我如何执行我的存储过程。当我直接从sql执行它时，该过程是有效的，但是当我从平板电脑上执行它时它不起作用

String itemshelf = DBshelf;// edittext for putting in values on set
String itemcard = DBcard;// edittext for putting in values on where
PreparedStatement preparedStatement = con.prepareStatement("EXEC [dbo].[spUpd_Location]");
                        preparedStatement.executeUpdate();

我的存储过程

ALTER PROCEDURE [dbo].[spUpd_Location]
   @itemshelf nvarchar(1000)=NULL
 , @itemcard nvarchar(1000)=NULL
 AS
SET NOCOUNT ON
UPDATE PS
SET [ShelfNumber]=@itemshelf
FROM [file].[ItemPart] PS
JOIN [file].[Item] P ON P.[id] = PS.[id]
where [ItemNumber]=@itemcard

您的存储过程需要两个参数，您需要为准备好的语句提供这些参数。您的SQL需要占用参数的占位符，并且需要在PreparedStatement对象上设置参数。您的代码看起来像是：

String itemshelf = DBshelf;// edittext for putting in values on set
String itemcard = DBcard;// edittext for putting in values on where
PreparedStatement preparedStatement = con.prepareStatement("EXEC [dbo].[spUpd_Location] ?, ?;");
preparedStatement.setString(1, itemshelf);
preparedStatement.setString(2, itemcard);
preparedStatement.executeUpdate();

如何从preparestatement执行storedprocedure
