DISQLite3 5.15.0 for D4 - Delphi 10.1 Berlin | 13 Mb
DISQLite3 implements a self-contained, embeddable, zero-configuration SQL database engine for Delphi (Embarcadero / CodeGear / Borland).Features include:
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.
DISQLite3 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

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.
DISQLite3 5.15.0
Added support for row values.
Allow deterministic SQL functions in the WHERE clause of a partial index.
Added support for SQLITE_DBCONFIG_MAINDBNAME.
Added the ability to VACUUM an ATTACH-ed database.
Enhance the fts5vocab virtual table to handle “ORDER BY term” efficiently.
Miscellaneous micro-optimizations reduce CPU usage by more than 7% on common workloads. Most optimization in this release has been on the front-end (sqlite3_prepare_v2).
Bug Fixes:
The multiply operator now correctly detects 64-bit integer overflow and promotes to floating point in all corner-cases.
Correct handling of columns with redundant unique indexes when those columns are used on the LHS of an IN operator.
Skip NULL entries on range queries in indexes on expressions.
Ensure that the AUTOINCREMENT counters in the sqlite_sequence table are initialized doing “Xfer Optimization” on “INSERT … SELECT” statements.
Make sure the ORDER BY LIMIT optimization works with IN operators on INTEGER PRIMARY KEYs.
