Question

I have a stored procedure which accepts a User defined table type called SeasonTable which looks like this:

SeasonTable

    [SeasonId] [int] NOT NULL,
    [SeasonName] [varchar](50) NOT NULL,
    [Month] [int] NULL, 
    [IsDeleted] [bit] NOT NULL

Stored procedure is like as shown below

CREATE PROCEDURE [dbo].[udpTest] 
(
    @STable dbo.SeasonTable READONLY
)   
AS
BEGIN
SELECT [SeasonName] as SeasonName,[SeasonId],[Month],[IsDeleted] 
    FROM @AdminBillingSeasonsTable
END

When I call this from C# application

private DataTable TestCreateDataTable()
{
            DataTable dt = new DataTable();

            dt.Columns.Add("SeasonName", typeof(string));
            dt.Columns.Add("SeasonId", typeof(int));                
            dt.Columns.Add("Month", typeof(int));
            dt.Columns.Add("IsDeleted", typeof(bool));
            dt.Rows.Add("season1",1, 4,  false);
            dt.Rows.Add("season2",2, 9, false);
            dt.Rows.Add("season3",3, 11,  false);
            return dt;
}

When I use the above table as param to SP from C# app it is throwing error:

unable to convert “season1” to int.

Does this mean the column order in C# app should be same as the column order in SQL?

Any help regarding this is highly appreciated.

Thanks in advance

Try Switching your column sequence something like this

 private DataTable TestCreateDataTable()
            {
                DataTable dt = new DataTable();

                dt.Columns.Add("SeasonId", typeof(int));     // seasonId and then
                dt.Columns.Add("SeasonName", typeof(string)); // seasonName
                dt.Columns.Add("Month", typeof(int));
                dt.Columns.Add("IsDeleted", typeof(bool));
                dt.Rows.Add("season1",1, 4,  false);
                dt.Rows.Add("season2",2, 9, false);
                dt.Rows.Add("season3",3, 11,  false);
                return dt;
            }
