DISQLite3 v5.41.4 for Delphi 11
DISQLite3 v5.41.4 for Delphi 11
DISQLite3 implements a self-contained, embeddable, zero-configuration SQL database engine for Delphi (Embarcadero / CodeGear / Borland).
Overview
ACID transactions, even after system crashes and power failures.
Zero-configuration – no setup or administration needed.
Implements most of SQL-92.
A complete database is stored in a single disk file.
Supports terabyte-sized databases and gigabyte-sized strings and blobs. Self-contained: no external dependencies, no DLLs.
Small footprint and smart linking: Only required code is compiled in, adding as little as 300 KB code space only.
Full Text Search (FTS) with customizable tokenizer, prefix matching, and optional word stemming for 15 languages.
Database AES encryption with SHA256 key generator.
Db.pas is not required, which allows DISQLite3 to compile with all flavours of Delphi, including Delphi Standard and Delphi Personal.
Faster than popular database engines for most common operations.
Simple, easy to use API.
Database files created with DISQLite3 can also be accessed by Linux and MacOS using the SQLite3 libraries.
SQL-92 Support
DISQLite3 Drive Catalog Demo ApplicationDISQLite3 understands most of the SQL-92 language standard:
ALTER TABLE
ANALYZE
ATTACH DATABASE
BEGIN TRANSACTION
Comments
COMMIT TRANSACTION
CREATE INDEX
CREATE TABLE
CREATE TRIGGER
CREATE VIEW
DELETE
DETACH DATABASE
DROP INDEX
DISQLite3 Mathematical Expression Evaluator Demo Applicationdrop TABLE
DROP TRIGGER
DROP VIEW
END TRANSACTION
EXPLAIN
Expressions
INSERT
ON CONFLICT clause
PRAGMA
REINDEX
REPLACE
ROLLBACK TRANSACTION
SELECT
UPDATE
VACUUM
The complete SQL syntax is described in full length in the DISQLite3 HTML Help, part of the installation package.
Simple Programming Interface
DISQLite3 Database Encryption Demo ApplicationDISQLite3 provides a comprehensive list of functions and procedures to manage database records with ease and efficiency. It includes the full SQLite3 functionality, plus a number of Delphi specific extras:
AnsiString, UnicodeString / WideString, and Variant support.
Database and Statement wrapper classes.
TDataSet support.
TStream support for BLOBs.
Growing number of Delphi example projects.
Despite of its rich set of features, a DISQLite3 database application can be realized with just three different function calls.
DISQLite3 v5.41.4 – 5 Oct 2022
This is a security release that addresses a single long-standing problem in the FTS3 extension. An attacker who is able to execute arbitrary SQL statements and who can create a corrupt database that is 2GB or larger in size might be able to trick FTS3 into overflowing an integer used to size a memory allocation, causing the allocation to be too small and ultimately resulting in a buffer overrun. It also includes fixes for other obscure weaknesses.
Fix a long-standing problem in the btree balancer that might, in rare cases, cause database corruption if the application uses an application-defined page cache.
Enhance SQLITE_DBCONFIG_DEFENSIVE so that it disallows CREATE TRIGGER statements if one or more of the statements in the body of the trigger write into shadow tables.
Fix a possible integer overflow in the size computation for a memory allocation in FTS3.
