* Should keep quoting behaivor of a time column value in sqlite3 adapterRyuta Kamizono2016-04-151-3/+8
| | | | | | | | | | | | | | | | | | | | Follow up to #24542. In MySQL and PostgreSQL, a time column value is saved as ignored the date part of it. But in SQLite3, a time column value is saved as a string. We should keep previous quoting behavior in sqlite3 adapter. ``` sqlite> CREATE TABLE "foos" ("id" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, "start" time(0), "finish" time(4)); sqlite> INSERT INTO "foos" ("start", "finish") VALUES ('2000-01-01 12:30:00', '2000-01-01 12:30:00.999900'); sqlite> SELECT "foos".* FROM "foos"; 1|2000-01-01 12:30:00|2000-01-01 12:30:00.999900 sqlite> SELECT "foos".* FROM "foos" WHERE "foos"."start" = '2000-01-01 12:30:00' LIMIT 1; 1|2000-01-01 12:30:00|2000-01-01 12:30:00.999900 sqlite> SELECT "foos".* FROM "foos" WHERE "foos"."start" = '12:30:00' LIMIT 1; sqlite> ```
* Properly serialize all JSON primitives in the AR JSON typeSean Griffin2016-04-132-9/+23
| | | | | | | | | | | | | | Previously we were assuming that the only valid types for encoding were arrays and hashes. However, any JSON primitive is an accepted value by both PG and MySQL. This does involve a minor breaking change in the handling of `default` in the schema dumper. This is easily worked around, as passing a hash/array literal would have worked fine in previous versions of Rails. However, because of this, I will not be backporting this to 4.2 or earlier. Fixes #24234
* Support microsecond datetime precision on MariaDB 5.3+.Jeremy Daer2016-04-082-21/+45
| | | | | | | | | We support microsecond datetime precision for MySQL 5.6.4+. MariaDB has supported it since 5.3.0, but even 10.x versions return a compatible version string like `5.5.5-10.1.8-MariaDB-log` which we parse as 5.5.5, before MySQL supported microsecond precision. Specialize our version check to account for MariaDB to fix.
* Use `QUOTED_TRUE` and `QUOTED_FALSE` instead of magic stringsyui-knk2016-04-051-2/+12
| | | | | | Because we define `QUOTED_TRUE` as `"1"` and `QUOTED_FALSE` as `"0"`. And add test cases to ensure this commit does not break current behavior even if the value of `attributes_before_type_cast` is false.

This change is to avoid extra `show variables` if `schema_migrations` table exists.

* [close #23009] Limit key lengthschneems2016-01-211-7/+29
| | | | | | | Mysql has a weird bug where it cannot index a string column of utf8mb4 if it is over a certain character limit. To get compatibility with msql we can add a limit to the key column. 191 characters is a very long key, it seems reasonable to limit across all adapters since using a longer key wouldn't be supported in mysql. Thanks to @kamipo for the original PR and the test refactoring. Conversation: https://github.com/rails/rails/pull/23009#issuecomment-171416629

* Refactor tz aware types, add support for PG rangesSean Griffin2016-01-081-0/+42
| | | | | | | | | | | | | | | | | This is an alternate implementation to #22875, that generalizes a lot of the logic that type decorators are going to need, in order to have them work with arrays, ranges, etc. The types have the ability to map over a value, with the default implementation being to just yield that given value. Array and Range give more appropriate definitions. This does not automatically make ranges time zone aware, as they need to be added to the `time_zone_aware` types config, but we could certainly make that change if we feel it is appropriate. I do think this would be a breaking change however, and should at least have a deprecation cycle. Closes #22875. /cc @matthewd

| | | | | | | | | | | | | | | | | | In MySQL 5.7.5 and up, ONLY_FULL_GROUP_BY affects handling of queries that use DISTINCT and ORDER BY. It requires the ORDER BY columns in the select list for distinct queries, and requires that the ORDER BY include the distinct column.
