What components can I use to use SQlite database with Delphi 6?
In Delphi XE7, FireDAC was integrated into Delphi.
Embarcadero purchased DA-SOFT in 2013, and FireDAC is their renamed AnyDAC.
Embarcadero plans to support and continue development of FireDAC, so it is now an excellent choice to be your Data Access Component for SQLite.
My Answer is AnyDAC in this case. We here currently use it and it works. Especially when you think that you get more than just what the database can do. http://www.da-soft.com/anydac/
