Hello everyone
I have made form in Forms 6.0. It has two blocks of data. Each of them is based on database table. One block B1 has elements:
Inventory number
Group

and the second block B2 has elements:
Group
Number
I display 12 rows of each block. I've made a relation between those two blocks: by the group. Block B1 is the master block.
First block (B1)display all rows, but in the second block B2 is display only one corresponding field. Rest 11 are empty.
Can anyone tell me how to synchronize those two blocks and display all corresponding rows?
Greetings

Are you expecting multiple rows in block 'B2' for each record in block 'B1'?

Well, if there is a master-detail relationship between those two blocks, master block will show all records (unless you restrict them by a query criteria), while detail block displays records which are "children" of the current master record.

If you want to display all master records and all detail records at the same time, remove master-detail relationship. But I guess that's not what you really want.

Hello
Those data come from two different tables. What I really want is to get data from one table (let's say master table) and by the key get data from that second table (slave table). The number of data from first table is 12 and are shown all, but corresponding data from second table (there is 12 row) are display only one.
Should I write some trigger that fetch those data from second table? When I delete relationship data from second table ar invisible.

Could you please post the table structure and some data.
Then it would be easier for us to give you a fast solution.

Cheers

I'd say that David already gave the answer ... are you sure that there is more than only one detail record for that particular master record you mentioned?

We know they come from different tables because you have told us that already Why are you people incapable of answering questions instead of saying the same stuff over again and again? I asked

Answer this question or I will lock this thread.

So where's the problem? Every master record has only one detail record, and you wonder where is the rest of them? The rest doesn't exist!

There is problem.
My form looks like this:


First blok B1 (master table)    Second Block B2(data extract
                                 by the key)
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

    row 1                         corresponding value fro row1
    row 2                         null(should be value for row2)
    row 3                         null(should be value for row3)
    row 4                         null(should be value for row4)
    row 5                         null(should be value for row5)

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Second block of data doesn't show all selected data. I don't know why,although it's source is table, just like for the first block B1.

But this is NOT how master-detail relationship works!!!

If you, however, want to do that, then remove master-detail relationship between those two blocks and use appropriate ORDER BY in both blocks.

This will be a complete mess, sooner or later. I wouldn't use it, no way.

I have ORDER BY. But if I delete relationship, even first row in block B2 disappears.

Ummm ... no. It doesn't disappear, but it never showed up! OK, the result is the same, but the principle isn't.

If you want to display records in both groups (WITHOUT master-detail relationship!), do (in the WHEN-NEW-FORM-INSTANCE trigger, for example)

GO_BLOCK('master');
EXECUTE_QUERY;

GO_BLOCK('detail');
EXECUTE_QUERY;

Now you'll have records in both blocks.
