I need to implement some sort of data (column) auto-completion in ODQ.
For example, I need to watch out for certain fields that is null / emplty. If it is, I have to query the value based on a series of rules from another table or datastore (e.g. if a certain non-null column has match on the look-up table, then get the value from there. if not, move to the next rule, which basically just another look-up query.)
I've been skimming ODQ docs and tutorials, but i just need a little bit quick starter since i'm on a very tight schedule. May pointing me to the first few low-level steps would get me to the right track.
