通用存储过程

1:删除
CREATE PROCEDURE Sp_deletedatabyCondition
@tablename nvarchar(100),
@condition nvarchar(200)
AS
BEGIN
DECLARE @Sql nvarchar(500)
SET @Sql='delete from '+@tablename+ ' where '+@condition
EXEC(@Sql)
END
GO

2：查询
CREATE PROCEDURE SP_getColumnsByCondition
@tablename nvarchar(100),
@columns nvarchar(300),
@condition nvarchar(200)

AS
BEGIN
DECLARE @sql nvarchar(1000)
SET @sql='select '+@columns+' from '+@tablename+ ' where 1=1 '+@condition
EXEC(@sql)
END
GO

3：更新
CREATE PROCEDURE Sp_UpdateTablebyCondition
@tablename nvarchar(100),
@condition nvarchar(300),
@columns nvarchar(500)
AS
BEGIN
DECLARE @sql nvarchar(1000)
SET @sql='update '+@tablename+' set '+@columns+' where '
+@condition
-- PRINT @sql
EXEC(@sql)
END
GO

调用

string tablename = "news",where="id=21";

    SqlParameter[] para = new SqlParameter[] {

    new SqlParameter("@tablename",tablename),

    new SqlParameter("@condition",where)

    };

    int result = DB.ExecuteProcCommand("Sp_deletedatabyCondition", para);

   if (result > 0)

   {

       Response.Write("删除成功");

   }

DB

 public static int ExecuteProcCommand(string proc,params SqlParameter[] values)

    {

        SqlConnection myconn = getcon();

        SqlCommand cmd = new SqlCommand(proc, myconn);

        cmd.Parameters.AddRange(values);

        cmd.CommandType = CommandType.StoredProcedure;

        int result = -1;

        try

        {

            result = cmd.ExecuteNonQuery();

        }

        catch (Exception ex)

        {

            throw ex;

        }

        finally

        {

            myconn.Close();

            myconn.Dispose();

        }

        return result;

    }

别的调用方法都是一样的就不写啦
