Prompting

The prompt function helps you supply the necessary information for the syntax of the statement you want to use. The prompt function can be used in any of these statement processing modes: *RUN, *VLD, and *SYN.

You have two options when using the prompter:

Type the verb of the statement before pressing F4=Prompt.

The statement is parsed and the clauses that are completed are filled in on the prompt displays.

If you type SELECT and press F4=Prompt, the following display appears:

                           Specify SELECT Statement
 
Type SELECT statement information.  Press F4 for a list.
 
  FROM tables . . . . . . . .  _____________________________________________
  SELECT columns  . . . . . .  _____________________________________________
  WHERE conditions  . . . . .  _____________________________________________
  GROUP BY columns  . . . . .  _____________________________________________

                                                                       Bottom

F3=Exit         F4=Prompt   F5=Refresh   F6=Insert line   F9=Specify subquery
F10=Copy line   F12=Cancel  F14=Delete line  F15=Split line  F24=More keys

Press F4=Prompt before typing anything on the Enter SQL Statements display. You are shown a list of statements. The list of statements varies and depends on the current interactive SQL statement processing mode. For syntax check mode with a language other than *NONE, the list includes all SQL statements. For run and validate modes, only statements that can be run in interactive SQL are shown. You can select the number of the statement you want to use. The system prompts you for the statement you selected.
If you press F4=Prompt without typing anything, the following display appears:
```
                             Select SQL Statement
 
Select one of the following:
 
     1. ALTER TABLE
     2. CALL
     3. COMMENT ON
     4. COMMIT
     5. CONNECT
     6. CREATE ALIAS
     7. CREATE COLLECTION
     8. CREATE INDEX
     9. CREATE PROCEDURE
    10. CREATE TABLE
    11. CREATE VIEW
    12. DELETE
    13. DISCONNECT
    14. DROP ALIAS
                                                                     More...
Selection
     __
 
F3=Exit   F12=Cancel
 
```

If you press F21=Display Statement on a prompt display, the prompter displays the formatted SQL statement as it was filled in to that point.

When Enter is pressed within prompting, the statement that was built through the prompt screens is inserted into the session. If the statement processing mode is *RUN, the statement is run. The prompter remains in control if an error is encountered.
