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.
Returns a new DBIx::Class::Storage::Statistics 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). 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).
Prints the specified string to our debugging filehandle. Provided to save our methods the worry of how to display the message.
Turn off all output if set to true.
Called when a transaction begins.
Called when a transaction is rolled back.
Called when a transaction is committed.
Called when a savepoint is created.
Called when a savepoint is released.
Called when rolling back to a savepoint.
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.
