Hi all,

I am at present working with Oracle Designer.  I am new to it.  See if anybody could  help me out.  here are my following questions.

1) We have something called Unbound and bound items in Ocl, designer.  I understand bound items are equivalent to db items and unbound items are equivalent to non-db items in Dev. forms.  Is it right? If we include any unbound item and select SQL expression, how to write queries in it?  say for e.g.my query shud be like
Difference between date of birth(db item) and sysdate.
2)  We have something called item groups in ocl. designer.  what is it.  When and how shud it be included in OCl. desginer.  Is it mandatory?
3) In D2k forms, We use to base a block on a table. once, we select the table, all the fields will be listed in the DB wizard.  In a similar way, how can we bring all the table fields listed in Orcl. Designer.  OR shud we include them manually?
4)  Difference between Module component and module sub-component?  Are they same like Blocks and items in D2k forms.
5) How to write validation triggers, and client side PL/sql units in oracle designer?
6) can we create object libraries on Oracle designer.  how?
7) How to declare Visual attributes on Ocl designer and include it to an item?

Any help please.

Thanks

1) You are right. The manipulation with unbound items is the same as with bound items is:
....WHERE :block1.date_of_birth BETWEEN sysdate-30 AND sysdate
2) Items groups are optional. It is used for grouping of items in a "logical" groups. You can add it/remove it everytime you need.
3) There is similar wizard in the Designere there. You can also add/remove items manually later.
4) You can read "Module sub-components" in the on-line help. Components and sub-components are items.
5) Validation triggers are generated automatically. You can write all triggers such way: Application Logic->Events
6) No, object libraries cannot be created in Designer. You can create only PLL libraries.
7) Visual attributes cannot be declared in Designer. You have to create an item in object liubrary (OLB) with desired attributes and use this item as template object in Designer.

Designer is a complex tool but it is worth to learn it and use it for form generation.
I advice you to read carefully Designer on-line help: "Generating Oracle Forms Applications". I have learned Designer such way.
