* implements AR::Relation#explainXavier Noria2011-11-053-1/+137
| | | | | | | | | | | | | | | | | | | This is a first implementation, EXPLAIN is highly dependent on the database and I have made some compromises. On one hand, the method allows you to run the most common EXPLAIN and that's it. If you want EXPLAIN ANALYZE in PostgreSQL you need to do it by hand. On the other hand, I've tried to construct a string as close as possible to the ones built by the respective shells. The rationale is that IMO the user should feel at home with the output and recognize it at first sight. Per database. I don't know whether this implementation is going to work well. Let's see whether people like it.

| * No "t." for the migration DSL!Akira Matsuda2011-05-202-10/+12
| | | | | | | | | | Now you can omit |t| block parameter and all the t. from your migration code, that means, the syntax looks more Rails-3-ish, like the routes DSL and ActionMailer DSL. Also, this change won't break any of your existing migration files, since the traditional syntax is still available.
* | dump_schema_information: explicitly order inserts into schema_migrations tableLaust Rud Jacobsen2011-10-311-1/+1
| | | | | | | | | | | | | | This change reduces churn in the db/development_structure.sql file when using :sql as active_record.schema_format, and makes comparing diffs much easier. Test ensures the output SQL-statements are lexically ordered by version.

| | | | | | | | | | To allow the use of prepared statements when changing schemas in postgres, the schema search path is added to the sql key.

* | Database adapters use a statement pool.Aaron Patterson2011-09-063-8/+46
| | | | | | | | | | | | Database adapters use a statement pool for limiting the number of open prepared statments on the database. The limit defaults to 1000, but can be adjusted in your database config by changing 'statement_limit'.

| | | | | | | | | | | | | | | | | | | | | | | | error. Strings tagged as binary will be stored in sqlite3 as blobs. It is an error to insert binary data to a string column, so an error is emitted in the log file. People are highly encouraged to track down the source of the binary strings and make sure that the encoding is set correctly before inserting to the database.

| | | | | | | | | | | | under eager_autoload. Due to the requires in that file, this caused ConnectionSpecification to be loaded, which references ActiveRecord::Base, which means the database connection is established. We do not want to connect to the database when Active Record is loaded, only when ActiveRecord::Base is first referenced by the user.
