DBIx::Class::Storage::Statistics - SQL Statistics SYNOPSIS
This class is called by DBIx::Class::Storage::DBI as a means of collecting statistics on its actions. Using this class alone merely prints the SQL executed, the fact that it completes and begin/end notification for transactions. To really use this class you should subclass it and create your own method for collecting the statistics as discussed in DBIx::Class::Manual::Cookbook. METHODS
new Returns a new DBIx::Class::Storage::Statistics object. debugfh Sets or retrieves the filehandle used for trace/debug output. This should be an IO::Handle compatible object (only the "print" method is used). Initially should be set to STDERR - although see information on the DBIC_TRACE environment variable. As getter it will lazily open a filehandle for you if one is not already set. print Prints the specified string to our debugging filehandle. Provided to save our methods the worry of how to display the message. silence Turn off all output if set to true. txn_begin Called when a transaction begins. txn_rollback Called when a transaction is rolled back. txn_commit Called when a transaction is committed. svp_begin Called when a savepoint is created. svp_release Called when a savepoint is released. svp_rollback Called when rolling back to a savepoint. query_start Called before a query is executed. The first argument is the SQL string being executed and subsequent arguments are the parameters used for the query. query_end Called when a query finishes executing. Has the same arguments as query_start. AUTHORS

DBIx::Class::Storage::DBI::Oracle::WhereJoins - Oracle joins in WHERE syntax support (instead of ANSI). PURPOSE
This module is used with Oracle < 9.0 due to lack of support for standard ANSI join syntax. SYNOPSIS
DBIx::Class should automagically detect Oracle and use this module with no work from you. DESCRIPTION
This class implements Oracle's WhereJoin support. Instead of: SELECT x FROM y JOIN z ON = It will write: SELECT x FROM y, z WHERE = It should properly support left joins, and right joins. Full outer joins are not possible due to the fact that Oracle requires the entire query be written to union the results of a left and right join, and by the time this module is called to create the where query and table definition part of the SQL query, it's already too late. METHODS
See DBIx::Class::SQLMaker::OracleJoins for implementation details. BUGS
Does not support full outer joins. Probably lots more. SEE ALSO
