To connect Delphi and C++Builder to an SQLite database via dbExpress, you must use a TSQLConnection component configured specifically for the SQLite driver framework. dbExpress provides a lightweight, database-independent layer that ensures fast performance.
Note: While dbExpress is fully functional, Embarcadero heavily recommends using FireDAC for modern SQLite development because dbExpress has been deprecated in recent RAD Studio releases. Step 1: Prepare the SQLite Client Library
dbExpress requires access to the native SQLite client library binaries to bridge your application to the database file.
Windows: Download the 32-bit or 64-bit precompiled sqlite3.dll directly from the SQLite Download Page. Place the DLL in your application’s executable directory or your Windows system directory (SysWOW64 for 32-bit, System32 for 64-bit).
macOS: No download is necessary. The operating system includes a built-in SQLite dynamic library located in /usr/lib/libsqlite3.dylib. Step 2: Configure the dbExpress Connection Components
Drop the required core components onto your VCL or FireMonkey form to build the connection pipeline: Connection Problems – Devart Forums
