Remarks
SQL Server Compact supports only the Text and TableDirect CommandTypes. An unsupported exception is thrown if StoredProcedure is specified.
TableDirect is the fastest way to retrieve data from SQL Server Compact, but cannot be used with joined tables.
The Connection, CommandType, and CommandText properties cannot be set if the current connection is performing an Execute or Fetch operation.
Examples
The following example creates an instance of SqlCeCommand and sets the CommandType and other properties.
Dim cmd As SqlCeCommand = conn.CreateCommand()
cmd.CommandText = "SELECT * FROM Categories ORDER BY CategoryID"
cmd.CommandType = CommandType.Text
cmd.UpdatedRowSource = UpdateRowSource.Both
SqlCeCommand cmd = conn.CreateCommand();
cmd.CommandText = "SELECT * FROM Categories ORDER BY CategoryID";
cmd.CommandType = CommandType.Text;
cmd.UpdatedRowSource = UpdateRowSource.Both;
