109 =item C<connect [@dbi_args]>
111 Connects to the database. If the configuration parameter
112 C<debug.dbix_log4perl> is set then the call is made through
113 L<DBIx::Log4per/connect>. Otherwise L<DBI/connect> is called directly.
115 In each case C<@dbi_args> is passed through as-is.
117 If C<@dbi_args> are not given they're generated by a call to
118 L</get_connect_args>.
120 =item C<get_connect_args [%options]>
122 Returns an array of database connection settings suitable to a call to
123 L<DBI/connect> or L</connect>. The settings to use are retrieved by
124 calling L<SL::DB/_register_db>.
126 This requires that a client has been set up with
127 L<SL::Auth/set_client> or that C<%::myconfig> contains legacy
130 C<%options> are optional database options like C<AutoCommit> (fourth
131 parameter to L<DBI/connect>). They're merged with default settings by
132 filtering them through L/get_options>.
134 =item C<get_datestyle [$dateformat]>
136 Returns the appropriate value for the C<SET DateStyle to...> SQL call
137 depending on C<$dateformat> (e.g. C<SQL, EUROPEAN> if C<$dateformat>
138 equals C<dd.mm.yy>). If C<$dateformat> is not given then it defaults
139 to C<$::myconfig{dateformat}>.
141 =item C<get_initial_sql>
143 Returns SQL commands that should be executed right after a connection
144 has been established. This is usually the call to configure the
145 C<DateStyle> format used by the database.
147 =item C<get_options [%options]>
149 Returns a hash reference of database options (fourth parameter to
150 L<DBI/connect>) merged with certain default options.
