It is possible to use a select statement in a lookup on a field. Following a select statement that fetches a record in a table, you can write .fieldName to reference a field in the table. These select statements must be used in expressions.

There is a difference between a normal select statement and a field select statement:

  • The field select statement operates directly on a table.

  • The normal select statement operates on a table buffer variable.

Example

  void selectFieldExamples ()
    {
        ;
        // Prints the NameRef field from the selected customer
        print (select CustTable order by AccountStatement).AccountStatement;
             pause;
     
        // Uses the balance field from the customer with AccountNum 3000
        if ((select custTable where CustTable.AccountNum == '3000').CreditMax < 50000)
          print "This customer has a credit maximum less than $50,000.";
          pause;
    }
