Question 1

How do I connect to an SQLite database using the wrapper in Lazarus?

Accepted Answer

Add the SQLite3Wrap unit to your uses clause, create a TSQLiteDatabase object, and call the Open method with the database file path. Ensure the SQLite shared library (sqlite3.so for Linux) is in your application's directory or system path.

Question 2

Is SQLite3-Delphi-FPC thread-safe?

Accepted Answer

Since it's a direct translation of the SQLite C API, it inherits SQLite's thread-safety when configured properly. However, the object wrapper might require additional synchronization if used across threads, as the README doesn't specify thread-safety details.

Question 3

SQLite3-Delphi-FPC vs ZeosLib for database access in Pascal?

Accepted Answer

SQLite3-Delphi-FPC is specialized for SQLite with a complete API translation and simple wrapper, ideal for direct control. ZeosLib supports multiple databases including SQLite but adds abstraction and might have more features like connection pooling, at the cost of complexity.

Question 4

Can I use SQLite extensions with this library?

Accepted Answer

Yes, through the direct C API translation, you can load extensions using functions like sqlite3_enable_load_extension. The object wrapper may not have built-in support, so you'd need to use the low-level API calls.

Question 5

What's the performance overhead of the object wrapper?

Accepted Answer

The wrapper adds a minimal overhead by encapsulating C API calls in Pascal objects, but it's designed for simplicity rather than optimization. For maximum performance, use the direct SQLite3 unit to avoid any wrapper layers.

Question 6

How do I handle errors with this wrapper?

Accepted Answer

The wrapper likely provides methods to check for errors, but the README doesn't detail it. Refer to the SQLite3Wrap source code for error handling patterns, or use the low-level API's sqlite3_errcode and sqlite3_errmsg functions directly.
