D.8. Alterações na distribuição 3.19.x

Version 3.19 is quite old now, and should be avoided if possible. This information is kept here for historical purposes only.

D.8.1. Alterações na distribuição 3.19.5

  • Some new functions, some more optimization on joins.

  • Should now compile clean on Linux (2.0.x).

  • Added functions DATABASE(), USER(), POW(), LOG10() (needed for ODBC).

  • In a WHERE with an ORDER BY on fields from only one table, the table is now preferred as first table in a multi-join.

  • HAVING and IS NULL or IS NOT NULL now works.

  • A group on one column and a sort on a group function (SUM(), AVG()...) didn't work together. Fixed.

  • mysqldump: Didn't send password to server.

D.8.2. Alterações na distribuição 3.19.4

  • Fixed horrible locking bug when inserting in one thread and reading in another thread.

  • Fixed one-off decimal bug. 1.00 was output as 1.0.

  • Added attribute 'Locked' to process list as information if a query is locked by another query.

  • Fixed full magic timestamp. Timestamp length may now be 14, 12, 10, 8, 6, 4 or 2 bytes.

  • Sort on some numeric functions could sort incorrectly on last number.

  • IF(arg,syntax_error,syntax_error) crashed.

  • Added functions CEILING(), ROUND(), EXP(), LOG() and SQRT().

  • Enhanced BETWEEN to handle strings.

D.8.3. Alterações na distribuição 3.19.3

  • Fixed SELECT with grouping on BLOB columns not to return incorrect BLOB info. Grouping, sorting and distinct on BLOB columns will not yet work as expected (probably it will group/sort by the first 7 characters in the BLOB). Grouping on formulas with a fixed string size (use MID() on a BLOB) should work.

  • Ao se fazer um full join (sem chave diretas) em tabelas múltiplas com campos BLOB, o BLOB vinha como lixo na saída.

  • Corrigido DISTINCT com colunas calculadas.
