Conversion failed during calling stored procedure
===

Here is my **stored procedure**:

[dbo].[DFW_Completed_Safety] (@StartDate VARCHAR(10), @Station VARCHAR(50), @EmployeeID INT)

When I **code** the following:

    try
    {
        sqlCon = new SqlConnection(connectionString);
        sqlCmd = new SqlCommand();
        sqlCmd.CommandType = CommandType.StoredProcedure;
        SqlDataAdapter daAC_CSM = new SqlDataAdapter();
        DataSet dsAC_CSM = new DataSet();
        sqlCmd.Connection = sqlCon;
        sqlCmd.CommandTimeout = 0;
        sqlCmd.CommandText = "DFW_Completed_Safety";
        sqlCmd.Parameters.AddWithValue("StartDate", startdate);
        sqlCmd.Parameters.AddWithValue("Station", station);    
        sqlCmd.Parameters.AddWithValue("EmployeeID", 0);
        sqlCon.Open();
        daAC_CSM.SelectCommand = sqlCmd;
        daAC_CSM.Fill(dsAC_CSM);
        sqlCon.Close();
        return dsAC_CSM;
    }
    catch (Exception ex)
    {
        throw ex;
    }

it throws the Exception: `Conversion failed when converting the varchar value 'd ' to data type int.`

**Things I tried:**

1- Many others post on StackOverflow suggested that `Convert.ToInt32(0);` would do it. Since 0 is an Int32 by default, this isn't a solution. <br>
2- Changing the method to receive varchar (send "0") and it doesn't work too.

Thanks for any ideas! (would be greater to keep the method signature to Int).
