Remarks

SQL Server Compact Edition supports only the Text and TableDirectCommandTypes. An unsupported exception is thrown if StoredProcedure is specified.

TableDirect is the fastest way to retrieve data from SQL Server Compact Edition, 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.

Example

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;
