using table methods after deleting a record.

I have a code like this (pseudo ...)

MyTable myTable;

MyTable2 myTable;

ttsbegin;

...

MyTable = MyTable::find(myId, true); // true = select for update

myTable.delete(); /*****/

MyTable2 = MyTable.getMyTable(); // getMyTable use some of the values myTable columns, in order to find the other table.

ttscommit;

========

Is there any problem doing MyTable2 = MyTable.getMyTable(); after doing myTable.delete();

Does the above can work sometimes, and sometimes cannot work properely?

(Not a guess, but I need a well known answer).

Thanks :)
