Hello,

I'm trying to figure out how to do a master detail detail form on Oracle forms properly.
There are 3 zones in my form. I uploaded the a simple script i'm using as an example.

I created a table emp2 and a table dept2. The table Emp2 has emp_id and emp_name. The table dept2 has dept_id, dept_seq_no,col_type and emp_id as well.

In the 1st zone, I query the emp2 table. When I do, I want only the col_type record 'update' in the 2nd zone. And furthermore, I want only the col_type record 'where' for the corresponding 'update' record in the 3rd zone.

So Zone 2 and 3 are used by the same table, but are differentiated by the col_type record.

I couldn't find anything like this on google. Hope it makes sense.

Thanks

That sounds wrong. EMP should reference DEPT, not vice versa (i.e. EMP2 should have DEPT2.DEPT_ID).

As of your question: use data block's WHERE clause property. You can set it while designing the form (if it won't change), or you can even modify it during runtime using SET_BLOCK_PROPERTY built-in (check Forms' Help for more info about it).

Alright then I will try that. And I see what you are saying about the data. I just made up the data a bit, for my issue with the separation 'update' and 'where' rows.

Thank you

The proper way to create a Master-Detail form is through the use of the Relations block properties. If configured correctly, you can have multiple Master-Detail relationships within a single form - which would give you the Master-Detail-Detail configuration you are looking for.

I agree with Littlefoot, your dependencies sound backward. With your configuration, the DEPT2 table would be the Master to the EMP2 table.

So Zone 2 and 3 are used by the same table, but are differentiated by the col_type record.

For this, you will need to have 2 data blocks each based on the DEPT2 table and a Relationship created between the EMP2 (Master) block and each of the DEPT2 blocks (eg: DEPT_UPDATE and DEPT_WHERE). The relationship will handle the initial linking of the blocks. Now, as Littlefoot suggests, you can set the WHERE property of each block to further filter the rows displayed; so DEPT_UPDATE's where clause would be: "COL_TYPE = 'WHERE'" and DEPT_WHERE would be: "COL_TYPE = 'WHERE'".
