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 = [])`.

The visibility of all internal protected methods was changed to private

A query may wait on a database-level lock, which could lead to a
deadlock between threads.

Per discussion in pull request #26622:
"Let's change it to PG::Error. The more specific classes mentioned are
subclasses, and the fact the raised exception is a PG::UndefinedColumn
doesn't change the fact that it's also a PG::Error." - matthewd

This clarifies the object that +ActiveRecord::Base.connection.execute+
will return when using Postgresql.

Because `sql_for_insert` is only called in `use_insert_returning?` is
true since #26002.

`exec_insert` cannot return last inserted id if `use_insert_returning?`

The current code base is not uniform. After some discussion,
we have chosen to go with double quotes by default.

|
|
|
|
|

`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.

Actually schema dumper/creation supports composite primary key (#21614).
Therefore it should not show the warning about composite primary key in
connection adapter.
This change moves the warning to `AttributeMethods::PrimaryKey` and
suppress the warning for habtm join table.
Fixes #25388.

habtm join tables commonly have two id columns and it's OK to make those
two id columns a primary key. This commit eliminates the warnings for
join tables that have this setup.

Simply `{update|delete}_sql` aliases to `{update|delete}`.
|
|
|
|

`connection.insert_sql` is almost the same as `connection.insert`.
|
|

Originally `connection#create` had aliased to `connection#insert` in PG
adapter. But it was broken by #7447. Re-alias `create` to `insert` for
fixing it.

Prior to this commit, Rails makes no differentiation between whether a
query uses bind parameters, and whether or not we cache that query as a
prepared statement. This leads to the cache populating extremely fast in
some cases, with the statements never being reused.
In particular, the two problematic cases are `where(foo: [1, 2, 3])` and
`where("foo = ?", 1)`. In both cases we'll end up quoting the values
rather than using a bind param, causing a cache entry for every value
ever used in that query.
It was noted that we can probably eventually change `where("foo = ?",
1)` to use a bind param, which would resolve that case. Additionally, on
PG we can change our generated query to be `WHERE foo = ANY($1)`, and
pass an array for the bind param. I hope to accomplish both in the
future.
For SQLite and MySQL, we still end up preparing the statements anyway,
we just don't cache it. The statement will be cleaned up after it is
executed. On postgres, we skip the prepare step entirely, as an API is
provided to execute with bind params without preparing the statement.
I'm not 100% happy on the way this ended up being structured. I was
hoping to use a decorator on the visitor, rather than mixing a module
into the object, but the way Arel has it's visitor pattern set up makes
it very difficult to extend without inheritance. I'd like to remove the
duplication from the various places that are extending it, but that'll
require a larger restructuring of that initialization logic. I'm going
to take another look at the structure of it soon.
This changes the signature of one of the adapter's internals, and will
require downstream changes from third party adapters. I'm not too
worried about this, as worst case they can simply add the parameter and
always ignore it, and just keep their previous behavior.
Fixes #21992.

Arel handles this for us automatically. Updated tests, as BindParam is
no longer a subclass of SqlLiteral. We should remove the second argument
to substitute_at entirely, as it's no longer used
|
|
|
|
|
|
| |
We end up re-ordering them either way when we construct the Arel AST (in order
to deal with rewhere, etc), so we shouldn't bother giving it a number in the
first place beforehand.

whether to exec with cache for Postgresql adapter
Reduces creating unused objects, with the most dramatic reduction in select_values which used to map(&:first) an array of single element arrays.

This was a common pattern:
```
query = author.posts.select(:title)
connection.select_one(query)
```
However `.select` returns a ActiveRecord::AssociationRelation, which has
the bind information, so we can use that to get the right sql query.
Also fix select_rows on postgress and sqlite3 that were not using the binds

This is to be consistent with the way the mysql2 adapter times queries
|
| |
|
| |
|
| |
|
|
|
|
|
|
|
|
|
| |
When the adapter is with prepared statement disabled and the binds array
is not empty the connection adapter will try to set the binds values and
will fail. Now we are checking if the adapter has the prepared statement
disabled.

This reverts commit 521035af530482d6d9ad2dae568eaeb0ab188e1c, reversing
changes made to 222011dbee842bbc60d3aaaa3145356b90a30fd1.
Reason: This broke the tests
|
| |
|
|
|
|
|
|
| |
* dependencies/autoload
* concern
* deprecation
|
| |
|
|
|
|
| |
It's sometimes hard to quickly find where deprecated call was performed, especially in case of migrating between Rails versions. So this is an attempt to improve the call stack part of the warning message by providing caller explicitly.

If your database supports setting the isolation level for a transaction,
you can set it like so:
Post.transaction(isolation: :serializable) do
# ...
end
Valid isolation levels are:
* `:read_uncommitted`
* `:read_committed`
* `:repeatable_read`
* `:serializable`
You should consult the documentation for your database to understand the
semantics of these different levels:
* http://www.postgresql.org/docs/9.1/static/transaction-iso.html
* https://dev.mysql.com/doc/refman/5.0/en/set-transaction.html
An `ActiveRecord::TransactionIsolationError` will be raised if:
* The adapter does not support setting the isolation level
* You are joining an existing open transaction
* You are creating a nested (savepoint) transaction
The mysql, mysql2 and postgresql adapters support setting the
transaction isolation level. However, support is disabled for mysql
versions below 5, because they are affected by a bug
(http://bugs.mysql.com/bug.php?id=39170) which means the isolation level
gets persisted outside the transaction.

This method was first seen in 045713ee240fff815edb5962b25d668512649478,
and subsequently reimplemented in
fb2325e35855d62abd2c76ce03feaa3ca7992e4f.
According to @jeremy, this is okay to remove. He thinks it was added
because at the time we didn't have much transaction state to keep track
of, and he viewed it as a hack for us to track it internally, thinking
it was better to ask the connection for the transaction state.
Over the years we have added more and more state to track, a lot of
which is impossible to ask the connection for. So it seems that this is
just a relic of the passed and we will just track the state internally
only.
