Regular expression used for getting accurate number of rows matched by an update statement.
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.
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).
