.net存儲過程通用select

創建存儲過程

 

create PROCEDURE [dbo].[SP_SelectByWhere]
(
  @strTableName nvarchar(200),
  @strWhere nvarchar(200)='',
  @strSelect nvarchar(300)= '*',
  @strOrder nvarchar(50)=''
)
AS
begin transaction
   declare @sql varchar(4000)
   begin
      set @sql= 'select '+ @strSelect+ ' from '+ @strTableName + ' ' +@strWhere + ' ' +@strOrder
      execute(@sql)
   end

 

類調用存儲過程

 

 public DataTable List()
    {
        string strSelect = "*";
        string strWhere = "where id=1";
        string strTableName = "users";
        SqlParameter[] param = new SqlParameter[]
        { 
                new SqlParameter("@StrSelect",strSelect),
                new SqlParameter("@strWhere",strWhere),
                new SqlParameter("@strTableName", strTableName),
                new SqlParameter("@strOrder", "")
        };
        SqlCommand cmd = new SqlCommand("SP_SelectByWhere", MyConn);
        cmd.CommandType = CommandType.StoredProcedure;
        if (param != null)
        {
            foreach (SqlParameter Parameter in param)
                cmd.Parameters.Add(Parameter);
        }
        return ExeDt(cmd);
    }
