| SQLite Expert Profesional 3.47.2 Dec 8, 2024 |
Fix a problem in text-to-floating-point conversion for SQLite that can cause values between '1.8446744073709550592eNNN' and '1.8446744073709551609eNNN' for any exponent NNN to be rendered incorrectly. In other words, some numeric text values where the first 16 significant digits are '1844674407370955' might be converted into the wrong floating-point value. See forum thread 569a7209179a7f5e. This problem only arises on x64 and i386 hardware. The problem was introduced in 3.47.0. Other minor bug fixes. |

Fix the makefiles so that they once again honored DESTDIR for the "install" target. Add the SQLITE_IOCAP_SUBPAGE_READ capability to the VFS, to work around issues on some non-standard VFSes caused by making SQLITE_DIRECT_OVERFLOW_READ the default in version 3.45.0. Fix problems with line endings in the new sqlite3_rsync.exe utility on Windows. Fix incorrect answers to certain obscure IN queries caused by new query optimizations added in the 3.47.0 release. Other minor bug fixes. |

Allow arbitrary expressions in the second argument to the RAISE function. If the RHS of the ->> operator is negative, then access array elements counting from the right. Fix a problem with rolling back hot journal files in the seldom-used unix-dotfile VFS. FTS5 tables can now be dropped even if they use a non-standard tokenizer that has not been registered. Fix the group_concat() aggregate function so that it returns an empty string, not a NULL, if it receives a single input value which is an empty string. Enhance the generate_series() table-valued function so that it is able to recognize and use constraints on its output value. Preupdate hooks now recognize when a column added by ALTER TABLE ADD COLUMN has a non-null default value. Performance optimizations: Improved reuse of subqueries associated with the IN operator, especially when the IN operator has been duplicated due to predicate push-down. Use a Bloom filter on subqueries on the right-hand side of the IN operator, in cases where that seems likely to improve performance. Ensure that queries like "SELECT func(a) FROM tab GROUP BY 1" only invoke the func() function once per row. No attempt is made to create automatic indexes on a column that is known to be non-selective because of its use in other indexes that have been analyzed. Adjustments to the query planner so that it produces better plans for star queries with a large number of dimension tables. Add the "order-by-subquery" optimization, that seeks to disable sort operations in outer queries if the desired order is obtained naturally due to ORDER BY clauses in subqueries. The "indexed-subtype-expr" optimization strives to use expressions that are part of an index rather than recomputing the expression based on table values, as long as the query planner can prove that the subtype of the expression will never be used. Miscellaneous coding tweaks for faster runtimes. Enhancements to SQLite-related command-line programs: Ad |
