TXQuery component
 

Version 01.02


TXQuery component is a TDataSet descendant component that can be used to query 
one or more TDataSet descendant components using SQL statements. It is implemented 
in Delphi 100% source code, no DLL required, because it has its own SQL syntax parser.
It can be very useful for TDataSet descendants components that do not use the BDE and 
that do not implement the SQL language.
You configure it by placing on a form or data module, one or more TDataSet descendant 
components (like TTable, TQuery, THalcyonDataSet, Flash Filer, Topaz, Apollo, etc.), then 
define in DataSets property of TXQuery, the list of TDataSet components that will be queried. 
Next you define the sql statement in SQL property (like TQuery) where you can use the 
DataSets defined, then set Active property to true and that's all. 
Almost all  standard SQL syntax is supported and more.

Features:
- SELECT, UPDATE, DELETE and INSERT statement are supported
- Can be filtered
- Help file included
- Ability to add your own functions without changing the source code, thru property and events
- etc.
