Question

I’m getting an error when trying to fill a data table with data from a MySQL query using the adapter.

VisualStudio it’s telling me the error, “Input String was not in a correct format,” is on the line with adapter.Fill(myDataTable); (The procedure is just a basic select statement that returns some rows with text, varchar, and datetime values.)

the method is called like this: GetDataTable("CALL SomeProc()");

public static DataTable GetDataTable(string query)
{
    string ConnString = ConfigurationManager.ConnectionStrings["randomconnstr"].ConnectionString.ToString();
    MySqlConnection conn = new MySqlConnection(ConnString);
    MySqlDataAdapter adapter = new MySqlDataAdapter();
    adapter.SelectCommand = new MySqlCommand(query, conn);

    DataTable myDataTable = new DataTable();

    conn.Open();
    try
    {
        adapter.Fill(myDataTable);
    }

    finally
    {
        conn.Close();
    }
    return myDataTable;
}

Answer 1

Your missing a quotation mark, it doesn’t look like you have closed the string.

GetDataTable(@"CALL SomeProc()");

EDIT **

Try Adding this :-

adapter.SelectCommand.CommandType = CommandType.StoredProcedure;
