Considering the relatively small amount of work it is to do this in your app
and the amount of complexity and code it would add to the engine, I don't
think I will implement such a creature.

What could be developed though is an external component to marry two
datasets together and then it could be encapsulated that way. If someone
wanted to contribute such a component I would add it in. I would also adjust
some internals to make it more feasible to accomplish as well.

Subject: [IBO] Suggestions for IBO v4 - Multiple Mastersources


> Hi list.
>
> I often encountered the need of multiple mastersources for TIB_Query.
Here's a short example:
>
> Tables:
> TABLE1:
> T1_ID INTEGER NOT NULL PRIMARY KEY,
> T1_INFO VARCHAR(32);
>
> TABLE2:
> T2_ID INTEGER NOT NULL PRIMARY KEY,
> T2_INFO VARCHAR(32);
>
> TABLE3:
> T1_ID INTEGER NOT NULL REFERENCES TABLE1(T1_ID),
> T2_ID INTEGER NOT NULL REFERENCES TABLE2(T2_ID),
> T3_INFO VARCHAR(32),
> PRIMARY KEY (T1_ID,T2_ID);
>
> I sometimes need two grids (one for Table1, the other for Table2) which
coresponding TIB_Queries to act like masters for a third TIB_Query selecting
rows from Table3.
> TIB_Query3 MasterLinks would look like
> TABLE3.T1_ID=TABLE1.T1_ID
> TABLE3.T2_ID=TABLE2.T2_ID
> MasterSources[] for TIB_Query3: [TIB_Datasource1,TIB_Datasource2].
>
> I'm aware this might be difficult to implement, that's why I'm asking you
guys. Would this be usefull for you also?
