Whether to convert tinyint columns to bool for this database
Set the #convert_tinyint_to_bool setting based on the default value.
# File lib/sequel/adapters/mysql2.rb, line 18 def initialize(opts={}) super self.convert_tinyint_to_bool = Sequel::MySQL.convert_tinyint_to_bool end
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)
: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).
: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).

Return the number of matched rows when executing a delete/update statement.
# File lib/sequel/adapters/mysql2.rb, line 66 def execute_dui(sql, opts={}) execute(sql, opts){|c| return c.affected_rows} end
Return the last inserted id when executing an insert statement.

Return the version of the MySQL server two which we are connecting.
