Implicit conversion from data type datetime to int

[7effrey]

Hi, I'm trying to retrieve some information from my database, but somehow i get this error:

Behind code:

public void binddata()
    {
        SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
              DataSet ds = new DataSet();
 
        SqlDataAdapter da = new SqlDataAdapter("getRoomNEquip2", con);
        da.SelectCommand.CommandType = CommandType.StoredProcedure;
         da.SelectCommand.Parameters.Add("@Location", SqlDbType.VarChar, 50);
 
        da.SelectCommand.Parameters["@Location"].Value = DropDownLocation.SelectedItem.Text;
 
 
        da.Fill(ds);
 
        ds.Relations.Add("myRelation",
            ds.Tables[0].Columns["ID"],
            ds.Tables[1].Columns["ID"]);
 
        MeetRoomList.DataSource = ds.Tables[0];
        MeetRoomList.DataBind();
 
    }

this is my stored procedure:

ALTER PROCEDURE [dbo].[Getroomnequip2] 
    @Location VARCHAR(50)
AS 
 
  BEGIN 
      CREATE TABLE #temp 
        (

        ) 
 
      INSERT INTO #temp 
      SELECT roomndato.mrn     AS name,

                                FULL JOIN meetroomtypes AS b 
                                  ON a.fk_type = b.TYPE

      WHERE  location = @Location 
      ORDER  BY name,

                      TYPE 
      FROM   #temp 
 
      SELECT * 
      FROM   #temp 
  END

The error message pretty much says it all

error: Implicit conversion from data type datetime to int

Someplace you have an int and you are trying to implicitly convert it to a datetime and the OS doesn't know how to do that.

If you are storing a date as an int in your database you will need to expressly tell your program how to convert it back to a datetime object.

i know what it means, but the thing is im not trying to convert anything. im just trying to read some data from the database. All my date fields are of the type datetime, and i dont understand why it says im trying to load it as an int.. how can i find out where the problem is?

I think the problem is in my stored procedure

I found the error. Apparently you must name the table content in the same order as you select them

CREATE TABLE #temp 
        ( 
             name varchar(50),
             id , 
             location varchar(50), 
             fk_type varchar(10), 
             fk_equipments int, 
             TYPE varchar(10), 
             fk_meetroom int, 
             status char(1), 
             note text, 
             fk_user int, 
             reg_date DateTime,
             date DateTime, 
        ) 
 
      INSERT INTO #temp
      SELECT roomndato.mrn     AS name, 
             a.id, 
             a.location, 
             a.fk_type, 
             b.fk_equipments, 
             b.TYPE, 
             c.fk_meetroom, 
             c.status, 
             c.note, 
             c.fk_user, 
             c.reg_date,

Hmm I would have said that to fix this problem you should use Explicit Casting when reading the values retrieved from the database. If you are expecting an Int, then specify that using explicit casting.
