DBIx::Class::Storage::Statistics - SQL Statistics
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.
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). By default it is initially set to STDERR - although see discussion of the DBIC_TRACE environment variable. Invoked as a getter it will lazily open a filehandle and set it to autoflush (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.
