The SELECT statement allows you to retrieve information from the database. This section describes how to execute a SELECT statement and how to handle the result set it returns.

To execute a SELECT statement

1. Declare a ULCommand object, which holds the query.

   ULCommand cmd;

2. Assign a statement to the object.

   cmd = conn.CreateCommand(); cmd.Command = "SELECT MyColumn FROM MyTable";

3. Execute the statement.

   Query results can be returned as one of several types of objects. In this example, a ULDataReader object is used. In the following code, the result of the SELECT statement contains a string, which is output to the command prompt.

   ULDataReader customerNames = prepStmt.ExecuteReader(); int fc = customerNames.GetFieldCount(); while( customerNames.MoveNext() ) { for ( int i = 0; i < fc; i++ ) { System.Console.Write(customerNames.GetString( i ) + " " ); } System.Console.WriteLine(); }
