<h2>Open a database</h2>
|
||||
<pre>

|
||||
</pre>
|
||||
<h2>Open an SQLite memory database</h2>
|
||||
<p>
|
||||
Without a filename argument, the sqlite adapter will setup a new sqlite
|
||||
database in memory.
|
||||
</p>
|
||||
<pre>

DB = Sequel.sqlite
|

</pre>

<h2>Logging SQL statements</h2>

DB = Sequel.sqlite '', :loggers => [Logger.new($stdout)]
|
||||
# or
|
||||
DB.loggers << Logger.new(...)
|
||||
</pre>
|

<h2>Using raw SQL</h2>

DB.run "CREATE TABLE users (name VARCHAR(255) NOT NULL, age INT(3) NOT NULL)"
|

<pre>

|

<h2>Insert rows</h2>
|
||||
<pre>
|

<h2>Update/Delete rows</h2>

<pre>
|
||||
dataset.filter(~:active).delete
|
||||
dataset.filter('price < ?', 100).update(:active => true)
|

<h2>Datasets are Enumerable</h2>

dataset.update(:updated_at => :DateValue.sql_function('1/1/2001'))
|

</pre>
|
||||
<h2>Schema Manipulation</h2>
|
||||
<pre>
|
||||
DB.create_table :items do
|
||||
primary_key :id
|
||||
String :name, :unique => true, :null => false
|
||||
TrueClass :active, :default => true
|
||||
foreign_key :category_id, :categories
|
||||
DateTime :created_at
|
||||
|
||||
index :created_at
|
||||
end
|
||||
|
||||
DB.drop_table :items
|
||||
|
||||
DB.create_table :test do
|
||||
String :zipcode
|
||||
enum :system, :elements => ['mac', 'linux', 'windows']
|
||||
end
|
||||
</pre>
|
||||
<h2>Aliasing</h2>
|
||||
<pre>
|
||||
DB[:items].select(:name.as(:item_name))
|
||||
DB[:items].select(:name___item_name)
|
||||
DB[:items___items_table].select(:items_table__name___item_name)
|
||||
# SELECT items_table.name AS item_name FROM items AS items_table
|
||||
</pre>
|
||||
<h2>Transactions</h2>
|
||||
<pre>
|
||||
DB.transaction do
|
||||
dataset.insert(:first_name => 'Inigo', :last_name => 'Montoya')
|
||||
dataset.insert(:first_name => 'Farm', :last_name => 'Boy')
|
||||
end # Either both are inserted or neither are inserted
|
||||
</pre>
|
||||
<p>
|
||||
Database#transaction is re-entrant:
|
||||
</p>
|
||||
<pre>
|
||||
DB.transaction do # BEGIN issued only here
|
||||
DB.transaction
|
||||
dataset << {:first_name => 'Inigo', :last_name => 'Montoya'}
|
||||
end
|
||||
end # COMMIT issued only here
|
||||
</pre>
|
||||
<p>
|
||||
Transactions are aborted if an error is raised:
|
||||
</p>
|
||||
<pre>
|
||||
DB.transaction do
|
||||
raise "some error occurred"
|
||||
end # ROLLBACK issued and the error is re-raised
|
||||
</pre>
|
||||
<p>
|
||||
Transactions can also be aborted by raising Sequel::Rollback:
|
||||
</p>
|
||||
<pre>
|
||||
DB.transaction do
|
||||
raise(Sequel::Rollback) if something_bad_happened
|
||||
end # ROLLBACK issued and no error raised
|
||||
</pre>
|
||||
<p>
|
||||
Savepoints can be used if the database supports it:
|
||||
</p>
|
||||
<pre>
|
||||
DB.transaction do
|
||||
dataset << {:first_name => 'Farm', :last_name => 'Boy'} # Inserted
|
||||
DB.transaction(:savepoint=>true) # This savepoint is rolled back
|
||||
dataset << {:first_name => 'Inigo', :last_name => 'Montoya'} # Not inserted
|
||||
raise(Sequel::Rollback) if something_bad_happened
|
||||
end
|
||||
dataset << {:first_name => 'Prince', :last_name => 'Humperdink'} # Inserted
|
||||
end
|
||||
</pre>
|
||||
<h2>Miscellaneous:</h2>
|
||||
<pre>
|
||||
dataset.sql # "SELECT * FROM items"
|
||||
dataset.delete_sql # "DELETE FROM items"
|
||||
dataset.where(:name => 'sequel').exists # "EXISTS ( SELECT * FROM items WHERE name = 'sequel' )"
|
||||
dataset.columns #=> array of columns in the result set, does a SELECT
|
||||
DB.schema(:items) => [[:id, {:type=>:integer, ...}], [:name, {:type=>:string, ...}], ...]
