Hi,

How to validate each record if the number of records displayed e.g. =2 in oracle forms

So even if the item has values, its showing that the value is not there. Warning is thrown in all cases. If it has values or its not.

So I printed the values of that block and it came null. Though the values are there in the item box.

Kindly suggest.

I don't understand what number of records has to do with their validation?

Anyway: WHEN-VALIDATE-RECORD block-level trigger might be what you are looking for.

As of the way you check values, why wouldn't you run the form in debug mode (if you're on Forms 9i or higher)? It helps a lot, simply by making things easier to see.

No, I meant what I said: WHEN-VALIDATE-RECORD block-level trigger etc.

If you want to validate items, then use WHEN-VALIDATE-ITEM (isn't that obvious?).

my doubt is ,the items has values and i have just set a warning on key-commit of form level,that if any of those items are null,it should show the warning.

It throws warning in both the cases.

I should assign its value into a variable in pre-query?

i mean store it somewhere

Since when i print the values of those items its coming as null,

though it has values in those items

I wouldn't validate anything in KEY-COMMIT; WHEN-VALIDATE- triggers should be used for that.

There's no need to store anything into any variables in PRE-QUERY (at least, I don't see any reason why would you do that).

Basically, you are saying that
- there's an item
- you see its value on the screen
- when checking whether the value exists, it appears to be empty

How exactly do you do that? Please, post a screenshot (which shows the form) and trigger code (properly formatted, enclosed into [code] tags to preserve formatting).

Hello,

You want the screenshot attached of the form? Trigger code of key-commit which is checking whether its null or not?
