Creating ID field at runtime
Posted on 2011-03-09
So I have a grid which is grouping records based on whether certain fields have filled in or not. The problem though is that certain records can fall into multiple categories. So, what I'm doing is using a SQL union to re-query and tag one instance of the record with a label ("Bid") and the second instance with another label ("Sale") and base grouping off of that.
Anyways, up to this point everything works fine an dandy. However, now I have the problem of not having a 'unique' key field, since a single record might come up within two or three separate groupings. The best solution I can think of (though that may not be the case) is to just created a separate key field column at runtime which has a seed of 1 and auto increments from there, but, I'm not sure how to code it, or if is possibly a feature built into delphi which can do this for me.
Any help would be appreciated. :)
