IBProvider v5.21. SQL query parser cache implementation

In this release of IBProvider v5, we have implemented caching the results of our own SQL query parser.

The SQL query parser is needed to define the type of query and its parameter list as well as to divide the script into separate expressions.

The SQL query cache (SQL Cache) supplements the server query cache (Stmt Cache) implemented way back in the earlier versions of IBProvider v3.

Both SQL Cache and Stmt Cache use separate threads to service their own state.

The SQL query cache works for both user queries and service queries of updatable rowset.

Kind Regards, IBProvider Team.

Python 3 Firebird-driver & Firebird-lib 1.0.0 released

The firebird-driver package provides official Python Database API 2.0-compliant driver. In addition to the minimal feature set of the standard Python DB API, this driver also exposes the new (interface-based) client API introduced in Firebird 3, and number of additional extensions and enhancements for convenient use of Firebird RDBMS. The driver is written as pure-Python package (requires Python 3.8+) on top of Firebird client library (fbclient.so/dll) using ctypes. Driver supports Firebird version 3.0 and higher.

You can download this driver from PyPI or or install it using pip.

Please note, that FDB driver is now considered as legacy driver, and its development will be discontinued together with 2.5 once Firebird 4.0 will be released later this year.

The driver uses firebird-base package, which is a collection of modules that have general applicability, like extended configuration, context-driven logging and trace/audit, hooks, work with structured binary buffers, extended data structures etc. The driver uses almost all features provided by “base” package, but specifically the use of hook mechanism and context-driven logging and trace/audit are potentially the most valuable improvements.


The firebird-lib package provides extensions to the firebird-driver.
This package provides modules for:

  • Work with Firebird database schema.
  • Work with Firebird monitoring tables.
  • Processing output from gstat Firebird utility.
  • Processing Firebird server log.
  • Processing output from Firebird server trace & audit sessions.

You can download this library from PyPI or or install it using pip.
