DBIx::Class::Storage::Statistics - SQL Statistics
This class is called by DBIx::Class::Storage::DBI as a means of collecting statistics on it's 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 the DBIx::Class::Manual::Cookbook manpage.
Returns a new the DBIx::Class::Storage::Statistics manpage object.
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.
Prints the specified string to our debugging filehandle, which we will attempt to open if we haven't yet. Provided to save our methods the worry of how to display the message.
Called when a transaction begins.
Called when a transaction is rolled back.
Called when a transaction is committed.
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.
Called when a query finishes executing. Has the same arguments as query_start.
