[size=15px]DISQLite3 5.23.0 – 26 Jan 2017
The output of sqlite3_trace_v2 now shows each individual SQL statement run within a trigger.
Description:
- 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 You can't view the links! Click here to register 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.

The output of sqlite3_trace_v2 now shows each individual SQL statement run within a trigger.
- Add the ability to read from WAL mode databases even if the application lacks write permission on the database and its containing directory, as long as the -shm and -wal files exist in that directory.
- Added the rtreecheck scalar SQL function to the R-Tree extension.
- Added the sqlite3_vtab_nochange and sqlite3_value_nochange interfaces to help virtual table implementations optimize UPDATE operations.
- Added the sqlite3_vtab_collation interface.
- Added support for the “^” initial token syntax in FTS5.
- New extensions:
- The Zipfile virtual table can read and write a ZIP Archive.
- The sqlite_btreeinfo eponymous virtual table for introspecting and estimating the sizes of the btrees in a database.
- The Append VFS is a VFS shim that allows an SQLite database to be appended to some other file. This allows (for example) a database to be appended to an executable that then opens and reads the database.
- The incremental_index_check is a read-only eponymous-only virtual table that checkes indexes.
- SQLAR compatible SQL compress and decompress functions.
- Query planner enhancements:
- The optimization that uses an index to quickly compute an aggregate min() or max() is extended to work with indexes on expressions.
- The decision of whether to implement a FROM-clause subquery as a co-routine or using query flattening now considers whether the result set of the outer query is “complex” (if it contains functions or expression subqueries). A complex result set biases the decision toward the use of co-routines.
- The planner avoids query plans that use indexes with unknown collating functions.
- The planner omits unused LEFT JOINs even if they are not the right-most joins of a query.
- Other performance optimizations:
- A smaller and faster implementation of text to floating-point conversion subroutine: sqlite3AtoF().
- Faster SQL parser.
- Provide the sqlite_offset(X) SQL function that returns the byte offset into the database file to the beginning of the record holding value X.
- Bug fixes:
- Infinite loop on an UPDATE that uses an OR operator in the WHERE clause.
- Incorrect query results when the skip-ahead-distinct optimization is used.
- Incorrect query results on a join with a ORDER BY DESC.
- Inconsistent result set column names between CREATE TABLE AS and a simple SELECT.
- Assertion fault when doing REPLACE on an index on an expression.
- Assertion fault when doing an IN operator on a constant index.
- Correct sqlite3_update_hook callback zDB argument type.
