Examples of using UDTs, UDFs, and LOBs

The following examples show how you can use user-defined types (UDTs), user-defined functions (UDFs), and large objects (LOBs) together in complex applications.

• Example: Define the UDT and UDFs
  Suppose you want to keep the electronic mail (e-mail) sent to your company in a table.
• Example: Use LOB function to populate the database
  Suppose you populate your table by transferring your e-mail that is maintained in files into DB2^® UDB for iSeries™.
• Example: Use UDFs to query instances of UDTs
  Suppose you need to know how much e-mail was sent by a specific customer regarding customer orders and you have the e-mail address of your customers in the customers table.
• Example: Use LOB locators to manipulate UDT instances
  Suppose you want to obtain information about a specific e-mail without having to transfer the entire e-mail into a host variable in your application program.
