Chapter 4 Examples of Using the DB Access Class Library

4.1 Use a Recordset

4.1.1 Create an object of the FJDB-SESSION class

The process of using the DB access class library to manipulate data begins by creating an object of the FJDB-SESSION class, or the top-ranking class of the DB access class library.

To create an object of the FJDB-SESSION class, proceed as follows:

1. Define the class.

   Define the class to use in the repository paragraph of the configuration section.
   

    CONFIGURATION SECTION.
    REPOSITORY.
        CLASS FJDB-SESSION
        CLASS FJDB-ERROR.
   

2. Define variables.

   Define the variables to use in the program.

    WORKING-STORAGE  SECTION.
   *Define object variables
    01  SESSION-A     USAGE OBJECT REFERENCE FJDB-SESSION.
    01  ERROR-A       USAGE OBJECT REFERENCE FJDB-ERROR.
      

3. Create an object of the FJDB-SESSION class.

   Using a CREATE-OBJECT method, create an object of the FJDB-SESSION class.

         INVOKE FJDB-SESSION "CREATE-OBJECT" USING ERROR-A
                                             RETURNING SESSION-A.
