I don't understand a word you are saying.
  • What is a "tabeau"?
  • "Search for my DB" is, I suppose, wrong terminology (I noticed that in your previous messages, but didn't pay attention): I *think* that "DB" is, actually, an Oracle "table" that resides in your schema. Is that so, or are you really searching through the whole database?
  • The last part of that sentence ("the problem must be ...") means what, exactly?

So, what should you do? Try to compose a meaningful and understandable message, for beginning.

Again, you are reinventing the wheel. How many times did we tell you that Forms does that for you?
- create a from (use data block wizard)
- don't write any code, none. No buttons. Nothing.
- run a form
- press <Enter query> button in a toolbar
- enter search criteria
- press <Execute query> button in a toolbar

If you, however, insist, then put EXECUTE_QUERY into button's WHEN-BUTTON-PRESSED trigger.

You are right - I don't understand you at all ...

goldray

the table already contains the result of "execute_query"

Which table? Who/what put execute_query results into that table and, above all, why?!?

goldray

when I press on the "search" button the new result will be displayed in the table

Nothing is displayed in a table. Table is a database object; it contains data. Front end (whether SQL*Plus, TOAD, your Forms application, whatever) DISPLAYS data stored in a table. So, is it the old wrong terminology issue? Is your "table", actually, a "tabular form layout" form block?

What do you need that cursor for? Are you SURE that it really does something (single quotes around :search.item)? If it is a data block, inserting records from a cursor into it will bring new problems (different FRM- error messages, such as "Do you want to save changes", possibly unique constraint violation and similar).

Unless you convince me opposite, I think that what I posted in the message #574111 is still valid. You enjoy in making simple things complex (and I'm unable to get the point).

I will explain in detail what I want ...
I have an interface that contains a tabular which contains records:
example:
123 Ryan
741 james

and I have a field named "item1" which contains default "%", for example, if this field I typed "% n" then I click on the "search" button in the tabular I have only this recording
123 Ryan

As I already said: Forms is capable of doing that.

- press <Enter query> button in a toolbar
- enter search criteria (type %n into the "employee name" item)
- press <Execute query> button in a toolbar

As you don't want it simple, then (in "Search" button's WHEN-BUTTON-PRESSED trigger): based on search item's value, compose a WHERE clause and - using SET_BLOCK_PROPERTY built in - create data block's DEFAULT_WHERE (or ONETIME_WHERE) property. Navigate to data block (GO_BLOCK) and EXECUTE_QUERY.

The where clause you want to be applied to the select statement that forms issues to the database.
Since your requirement still isn't clear to us we can't really tell you what to put.

You would use 2 apostrophes to represent one.
''
instead of 
'
