Data retrieval: SELECT


Use the SELECT statement to retrieve information from the database.

To execute a SELECT query using ExecuteQuery:

  1. Create a new prepared statement and result set.

    PreparedStatement prepStmt;
  2. Assign a prepared statement to your newly created PreparedStatement object.

    prepStmt = conn.prepareStatement(
       "SELECT MyColumn FROM MyTable");
  3. Execute the statement.

    In the following code, the result of the SELECT query contain a string, which is output to a command prompt.

    ResultSet customerNames = prepStmt.executeQuery();
    customerNames.moveBeforeFirst();
    while( customerNames.moveNext() ) {
       for ( int i = 1; 
             i <= customerNames.schema.getColumnCount(); 
             i++ ) {
          System.out.print(
            customerNames.getString( i ) + " "
            );
          System.out.println();
      }
    }
