SqlDataAdapter 使用存储过程

A:
//以下是返回相册图片信息
public static DataSet ImageMessage(string mvName)
{
SqlConnection myCon = CreateConn.conn();
////string MvName = "美女";
//string strSQL = "select * from FImage where Mv_Id=(select Mv_Id from FMv where Mv_Name='" + mvName + "')";
//SqlDataAdapter sda = new SqlDataAdapter(strSQL, myCon);
//DataSet ds = new DataSet();
//sda.Fill(ds, "ffc");
//return ds;
SqlDataAdapter sda = new SqlDataAdapter("ImageMessage", myCon);//ImageMessage为存储过程名
sda.SelectCommand.CommandType = CommandType.StoredProcedure;
SqlParameter spt = new SqlParameter("@mvName", SqlDbType.VarChar, 20);
spt.Direction = ParameterDirection.Input;
spt.Value = mvName;
sda.SelectCommand.Parameters.Add(spt);
DataSet ds = new DataSet();
sda.Fill(ds, "ffc");
return ds;
}

B: SqlDataAdapter可以使用存储过程,并使用参数
SqlDataAdapter objAdapter=new SqlDataAdapter("TreeView_Select",objConn);
objAdapter.SelectCommand.CommandType=CommandType.StoredProcedure;
objAdapter.SelectCommand.Parameters.Add("@ParentID",SqlDbType.Char,36);
objAdapter.SelectCommand.Parameters["@ParentID"].Value=ParentID;
objAdapter.SelectCommand.Parameters.Add("@UserID",SqlDbType.Char,36);
objAdapter.SelectCommand.Parameters["@UserID"].Value=UserID;
objAdapter.SelectCommand.Parameters.Add("@DepartID",SqlDbType.Char,36);
objAdapter.SelectCommand.Parameters["@DepartID"].Value=DepartID;
objAdapter.Fill(objDt);

答5：
CREATE PROCEDURE [dbo].[TreeView_Select]
@ParentID char(36),
@UserID char(36),
@DepartID char(36)
AS
if @ParentID<>''
select id,text,url from treeview where parentid=@Parentid and ((departid is null and userid is null) or PATINDEX('%'+@DepartID+'%',departid)<>0 or PATINDEX('%'+@UserID+'%',userid)<>0) order by posion
else
select id,text,url from treeview where parentid is null and ((departid is null and userid is null) or PATINDEX('%'+@DepartID+'%',departid)<>0 or PATINDEX('%'+@UserID+'%',userid)<>0) order by posion
