class Sequel::MySQL::Database

  1. lib/sequel/adapters/mysql.rb
Superclass: Sequel::Database

Attributes

conversion_procs [R]

Hash of conversion procs for the current database
convert_invalid_date_time [R]

By default, Sequel raises an exception if in invalid date or time is used. However, if this is set to nil or :nil, the adapter treats dates like 0000-00-00 and times like 838:00:00 as nil values. If set to :string, it returns the strings as is.
convert_tinyint_to_bool [R]

Whether to convert tinyint columns to bool for the current database

Public Instance methods

connect(server)

Connect to the database. In addition to the usual database options, the following options have effect:

:auto_is_null

Set to true to use MySQL default behavior of having a filter for an autoincrement column equals NULL to return the last inserted row.

:charset

Same as :encoding (:encoding takes precendence)

:compress

Set to false to not compress results from the server

:config_default_group

The default group to read from the in the MySQL config file.

:config_local_infile

If provided, sets the Mysql::OPT_LOCAL_INFILE option on the connection with the given value.

:connect_timeout

Set the timeout in seconds before a connection attempt is abandoned.

:encoding

Set all the related character sets for this connection (connection, client, database, server, and results).

:read_timeout

Set the timeout in seconds for reading back results to a query.

:socket

Use a unix socket file instead of connecting via TCP/IP.

:timeout

Set the timeout in seconds before the server will disconnect this connection (a.k.a @@wait_timeout).
