* / Correctly dump native timestamp types for MySQLRyuta Kamizono2017-02-233-2/+18
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The native timestamp type in MySQL is different from datetime type. Internal representation of the timestamp type is UNIX time, This means that timestamp columns are affected by time zone. ``` > SET time_zone = '+00:00'; Query OK, 0 rows affected (0.00 sec) > INSERT INTO time_with_zone(ts,dt) VALUES (NOW(),NOW()); Query OK, 1 row affected (0.02 sec) > SELECT * FROM time_with_zone; +---------------------+---------------------+ | ts | dt | +---------------------+---------------------+ | 2016-02-07 22:11:44 | 2016-02-07 22:11:44 | +---------------------+---------------------+ 1 row in set (0.00 sec) > SET time_zone = '-08:00'; Query OK, 0 rows affected (0.00 sec) > SELECT * FROM time_with_zone; +---------------------+---------------------+ | ts | dt | +---------------------+---------------------+ | 2016-02-07 14:11:44 | 2016-02-07 22:11:44 | +---------------------+---------------------+ 1 row in set (0.00 sec) ```

| * Extract `quoted_binary` and use it rather than override `_quote`Ryuta Kamizono2016-09-271-9/+3
| | | | | | | | | | | | | | Each databases have different binary representation. Therefore all adapters overrides `_quote` for quoting binary. Extract `quoted_binary` for quoting binary and use it rather than override `_quote`.
* | Fix bigint primary key with unsignedRyuta Kamizono2017-02-101-1/+1
| | | | | | | | | | | | | | Currently schema dumper lost the unsigned option when primary key is defined as bigint with unsigned. This commit fixes the issue. Closes #27960
* | Refactor `ColumnDefinition` to contain `options` hashRyuta Kamizono2017-02-092-29/+4
| | | | | | | | | | | | Column options are passed as an hash args then used as `options` hash in `add_column_options!`. Converting args to attributes is inconvinient for using options as an hash.
* | Correctly dump integer-like primary key with default nilRyuta Kamizono2017-02-041-10/+5
| | | | | | | | | | | | | | The PR #27384 changed integer-like primary key to be autoincrement unless an explicit default. This means that integer-like primary key is restored as autoincrement unless dumping the default nil explicitly. We should dump integer-like primary key with default nil correctly.
* | Virtual/generated column support for MySQL 5.7.5+ and MariaDB 5.2.0+Ryuta Kamizono2017-02-014-12/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MySQL generated columns: https://dev.mysql.com/doc/refman/5.7/en/create-table-generated-columns.html MariaDB virtual columns: https://mariadb.com/kb/en/mariadb/virtual-computed-columns/ Declare virtual columns with `t.virtual name, type: …, as: "expression"`. Pass `stored: true` to persist the generated value (false by default). Example: create_table :generated_columns do |t| t.string :name t.virtual :upper_name, type: :string, as: "UPPER(name)" t.virtual :name_length, type: :integer, as: "LENGTH(name)", stored: true t.index :name_length # May be indexed, too! end Closes #22589
* | Tweak bigint PK handlingMatthew Draper2017-01-182-6/+4
| | | | | | | | | | | | * Don't force PKs on tables that have explicitly opted out * All integer-like PKs are autoincrement unless they have an explicit default
* | Fix `select_rows` method signature for consistencyRyuta Kamizono2017-01-041-4/+6
| | | | | | | | | | | | | | | | Related #22973, #24708. `select_all`, `select_one`, `select_value`, and `select_values` method signature is `(arel, name = nil, binds = [])`. But `select_rows` is `(sql, name = nil, binds = [])`.

* activerecord/mysql2: Avoid setting @connection to nil, just close itDylan Thacker-Smith2016-09-081-10/+6
| | | | | | | | | | By doing `@connection = nil` that means that we need nil checks before it is used anywhere, but we weren't doing those checks. Instead, we get a NoMethodError after using a connection after it fails to reconnect. Neither of the other adapters set @connection to nil, just the mysql2 adapter. By just closing it, we avoid the need to check if we have a connection object and it will produce an appropriate exception when used.
* Remove unused `blob_or_text_column?` methodRyuta Kamizono2016-08-191-4/+0

* Remove text default treated as an empty string in non-strict modeRyuta Kamizono2016-08-192-23/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Strict mode controls how MySQL handles invalid or missing values in data-change statements such as INSERT or UPDATE. If strict mode is not in effect, MySQL inserts adjusted values for invalid or missing values and produces warnings. ```ruby def test_mysql_not_null_defaults_non_strict using_strict(false) do with_mysql_not_null_table do |klass| record = klass.new assert_nil record.non_null_integer assert_nil record.non_null_string assert_nil record.non_null_text assert_nil record.non_null_blob record.save! record.reload assert_equal 0, record.non_null_integer assert_equal "", record.non_null_string assert_equal "", record.non_null_text assert_equal "", record.non_null_blob end end end ``` It is inconsistent with other types that only text/blob defaults treated as an empty string. This commit fixes the inconsistency.

* Make `name` and `binds` to optional args for `exec_{insert,update,delete}`Ryuta Kamizono2016-08-041-1/+1
| | | | | | `insert`, `update`, `delete`, and `exec_query` have a default value against `name` and `binds`. But `exec_insert`, `exec_update`, and `exec_delete` not have. It is an inconvenience and inconsistent.

| | | | | | | | | | | | | | | | The implementation from abstract/database_statements.rb seems to work just fine. And with ActiveRecord::Result now implementing an optimized #first method, the performance concerns previously addressed in https://github.com/rails/rails/commit/bf79aa4fc14aeb2646331e767038acf0b77e9e7f should not be an issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | Comments are specified in migrations, stored in database itself (in its schema), and dumped into db/schema.rb file. This allows to generate good documentation and explain columns and tables' purpose to everyone from new developers to database administrators. For PostgreSQL and MySQL only. SQLite does not support comments at the moment.
