It's possibe define the priority between branches???

Anonymous — Sat, 16 Nov 2024 14:37:31 GMT

If I have an tDBInput with two main rows, how can I define the priority of execution of this branches?
I need that the "row2" executes before "row1" (see image in attach)
#row2
(creates 'N' files)
#row1
(appends information on the files that row2 creates).

Thanks in advance

Unfortunately, you can't define the order of row2 Vs row1 because the source component is not a tMap. tMap can manage the order of its output. See related 467.
In your case, insert a tMap after tDBInput_2 and link tUniqRow_1 and tMap_1 to this inserted tMap.

I did that, but i think that the tUniqRow (in row2) adulterates the data of the row1.
--> row2 it's good, because the output must be 3 rows, so it's correct.
--> row1 or tLogRow_3 must be 7 rows...that's why I think that the Row2 is changing the data flow...
Any idea to pass this behaviour???

There is a bug when you use a tUniqRow on a branch: if tUniqRow rejects the row, all branches are bypassed.

So there's nothing I can do right?
I already found a solution but forces me to read from the database again.
That bug will be fix in the M3 release?

OK, it has been a long time since I know this bug, I should have fixed it a long time ago. See 773

Hi,
I see that this bug has been already fixed, I'm working with release M2, it's possible to upgrade this bug? Or I must wait for another release?
Thanks

I really wanted this bug fixed in 2.0.0M3, but we had a GUI problem on tUniqRow and I couldn't fix it for 2.0.0M3. It is fixed for 2.0.0RC1. If you want the fix as fast as possible, copy/paste the content of modified files in 2705 (as declared in 773).
