DBIx::Class::Storage::Statistics(3)  User Contributed Perl Documentation DBIx::Class::Storage::Statistics(3)



NAME
       DBIx::Class::Storage::Statistics - SQL Statistics

SYNOPSIS
DESCRIPTION
       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.
