### Open a database
|
||||
|
||||
require 'rubygems'
|
||||
require 'sequel'
|
||||
|
||||
DB = Sequel.sqlite('my_blog.db')
|
||||
DB = Sequel.connect('postgres://user:password@localhost/my_db')
|
||||
DB = Sequel.postgres('my_db', :user => 'user', :password => 'password', :host => 'localhost')
|
||||
DB = Sequel.ado('mydb')
|
||||
|
||||
### Open an SQLite memory database
|
||||
|
||||
Without a filename argument, the sqlite adapter will setup a new sqlite database in memory.
|
||||
|
||||
DB = Sequel.sqlite
|
||||
|
||||
### Logging SQL statements
|
||||
|
||||
require 'logger'
|
||||
DB = Sequel.sqlite '', :loggers => [Logger.new($stdout)]
|
||||
# or
|
||||
DB.loggers << Logger.new(...)
|
||||
|
||||
### Using raw SQL
|
||||
|
||||
DB.run "CREATE TABLE users (name VARCHAR(255) NOT NULL, age INT(3) NOT NULL)"
|
||||
dataset = DB["SELECT age FROM users WHERE name = ?", name]
|
||||
dataset.map(:age)
|
||||
DB.fetch("SELECT name FROM users") do |row|
|
||||
p row[:name]
|
||||
end
|
||||
|
||||
### Create a dataset
|
||||
|
||||
dataset = DB[:items]
|
||||
dataset = DB.from(:items)
|
||||
|
||||
### Most dataset methods are chainable
|
||||
|
||||
dataset = DB[:managers].where(:salary => 5000..10000).order(:name, :department)
|
||||
|
||||
### Insert rows
|
||||
|
||||
dataset.insert(:name => 'Sharon', :grade => 50)
|
||||
|
||||
### Retrieve rows
|
||||
|
||||
dataset.each{|r| p r}
|
||||
dataset.all # => [{...}, {...}, ...]
|
||||
dataset.first # => {...}
|
||||
|
||||
### Update/Delete rows
|
||||
|
||||
dataset.filter(~:active).delete
|
||||
dataset.filter('price < ?', 100).update(:active => true)
|
||||
|
||||
### Datasets are Enumerable
|
||||
|
||||
dataset.map{|r| r[:name]}
|
||||
dataset.map(:name) # same as above
|
||||
|
||||
dataset.inject(0){|sum, r| sum + r[:value]}
|
||||
dataset.sum(:value) # same as above
|
||||
|
||||
### Filtering (see also doc/dataset_filtering.rdoc)
|
||||
|
||||
#### Equality
|
||||
|
||||
dataset.filter(:name => 'abc')
|
||||
dataset.filter('name = ?', 'abc')
|
||||
|
||||
#### Inequality
|
||||
|
||||
dataset.filter{value > 100}
|
||||
dataset.exclude{value <= 100}
|
||||
|
||||
#### Inclusion
|
||||
|
||||
dataset.filter(:value => 50..100)
|
||||
dataset.where{(value >= 50) & (value <= 100)}
|
||||
|
||||
dataset.where('value IN ?', [50,75,100])
|
||||
dataset.where(:value=>[50,75,100])
|
||||
|
||||
dataset.where(:id=>other_dataset.select(:other_id))
|
||||
|
||||
#### Subselects as scalar values
|
||||
|
||||
dataset.where('price > (SELECT avg(price) + 100 FROM table)')
|
||||
dataset.filter{price > dataset.select(avg(price) + 100)}
|
||||
|
||||
#### LIKE/Regexp
|
||||
|
||||
DB[:items].filter(:name.like('AL%'))
|
||||
DB[:items].filter(:name => /^AL/)
|
||||
|
||||
#### AND/OR/NOT
|
||||
|
||||
DB[:items].filter{(x > 5) & (y > 10)}.sql
|
||||
# SELECT * FROM items WHERE ((x > 5) AND (y > 10))
|
||||
|
||||
DB[:items].filter({:x => 1, :y => 2}.sql_or & ~{:z => 3}).sql
|
||||
# SELECT * FROM items WHERE (((x = 1) OR (y = 2)) AND (z != 3))
|
||||
|
||||
#### Mathematical operators
|
||||
|
||||
DB[:items].filter((:x + :y) > :z).sql
|
||||
# SELECT * FROM items WHERE ((x + y) > z)
|
||||
|
||||
DB[:items].filter{price - 100 < avg(price)}.sql
|
||||
# SELECT * FROM items WHERE ((price - 100) < avg(price))
|
||||
|
||||
### Ordering
|
||||
|
||||
dataset.order(:kind)
|
||||
dataset.reverse_order(:kind)
|
||||
dataset.order(:kind.desc, :name)
|
||||
|
||||
### Limit/Offset
|
||||
|
||||
dataset.limit(30) # LIMIT 30
|
||||
dataset.limit(30, 10) # LIMIT 30 OFFSET 10
|
||||
|
||||
### Joins
|
||||
|
||||
DB[:items].left_outer_join(:categories, :id => :category_id).sql
|
||||
# SELECT * FROM items LEFT OUTER JOIN categories ON categories.id = items.category_id
|
||||
|
||||
DB[:items].join(:categories, :id => :category_id).join(:groups, :id => :items__group_id)
|
||||
# SELECT * FROM items INNER JOIN categories ON categories.id = items.category_id INNER JOIN groups ON groups.id = items.group_id
|
||||
|
||||
### Aggregate functions methods
|
||||
|
||||
dataset.count #=> record count
|
||||
dataset.max(:price)
|
||||
dataset.min(:price)
|
||||
dataset.avg(:price)
|
||||
dataset.sum(:stock)
|
||||
|
||||
dataset.group_and_count(:category)
|
||||
dataset.group(:category).select(:category, :AVG.sql_function(:price))
|
||||
|
||||
### SQL Functions / Literals
|
||||
|
||||
dataset.update(:updated_at => :NOW.sql_function)
|
||||
dataset.update(:updated_at => 'NOW()'.lit)
|
||||
|
||||
dataset.update(:updated_at => "DateValue('1/1/2001')".lit)
|
||||
dataset.update(:updated_at => :DateValue.sql_function('1/1/2001'))
|
||||
|
||||
### Schema Manipulation
|
||||
|
||||
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
|
||||
|
||||
### Aliasing
|
||||
|
||||
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
|
||||
|
||||
### Transactions
|
||||
|
||||
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
|
||||
|
||||
Database#transaction is re-entrant:
|
||||
|
||||
DB.transaction do # BEGIN issued only here
|
||||
DB.transaction
|
||||
dataset << {:first_name => 'Inigo', :last_name => 'Montoya'}
|
||||
end
|
||||
end # COMMIT issued only here
|
||||
|
||||
Transactions are aborted if an error is raised:
|
||||
|
||||
DB.transaction do
|
||||
raise "some error occurred"
|
||||
end # ROLLBACK issued and the error is re-raised
|
||||
|
||||
Transactions can also be aborted by raising Sequel::Rollback:
|
||||
|
||||
DB.transaction do
|
||||
raise(Sequel::Rollback) if something_bad_happened
|
||||
end # ROLLBACK issued and no error raised
|
||||
|
||||
Savepoints can be used if the database supports it:
|
||||
|
||||
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
|
||||
|
||||
### Miscellaneous:
|
||||
|
||||
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, ...}], ...]

|

dataset.update(:updated_at => :DateValue.sql_function('1/1/2001'))
|
||||
|
||||
== Schema Manipulation
|
||||
|
||||
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
|
||||
|
||||
== Aliasing
|
||||
|
||||
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
|
||||
|
||||
== Transactions
|
||||
|
||||
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
|
||||
|
||||
Database#transaction is re-entrant:
|
||||
|
||||
DB.transaction do # BEGIN issued only here
|
||||
DB.transaction
|
||||
dataset << {:first_name => 'Inigo', :last_name => 'Montoya'}
|
||||
end
|
||||
end # COMMIT issued only here
|
||||
|
||||
Transactions are aborted if an error is raised:
|
||||
|
||||
DB.transaction do
|
||||
raise "some error occurred"
|
||||
end # ROLLBACK issued and the error is re-raised
|
||||
|
||||
Transactions can also be aborted by raising Sequel::Rollback:
|
||||
|
||||
DB.transaction do
|
||||
raise(Sequel::Rollback) if something_bad_happened
|
||||
end # ROLLBACK issued and no error raised
|
||||
|
||||
Savepoints can be used if the database supports it:
|
||||
|
||||
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
|
||||
|
||||
== Miscellaneous:
|
||||
|
||||
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, ...}], ...]
