<p><b>Question:</b>
Why is the parameter for MASTER_ID field in InsertSQL has a name
different from the that of the column?</p>
<p>
<b>Answer:</b>
SQL Generator is a very simple thing. It does not trace master-detail
links and foreign keys to get relations among fields. It generates
standard modifying queries, but if you need to use
more complicated
links, you should modify such queries manually.<br>

Our 911 dispatch center needed a program to monitor the status of equipment used in emergency situations. If one dispatcher modified the status of a piece of equipment, all the other dispatchers needed to see this change immediately. The most elegant way to implement this was by using Firebird Events to asynchronously notify all the users whenever a pertinent change had occurred at the database server. After failing to implement this myself using the Firebird API, I bought a copy of FIBPlus. I dropped a Database, EventAlert and ErrorHandler control into a C++ Builder DataModule and within minutes I had all the functionality I needed. I was able to complete the project quickly and the users are thrilled with the results because I gave them more features than they originally asked for. >>
