NAME

DBIx::Class::QueryLog - Log queries for later analysis.

VERSION

Version 1.0.1

SYNOPSIS

DBIx::Class::QueryLog 'logs' each transaction and query executed so you can analyze what happened in the 'session'. It must be installed as the debugobj in DBIx::Class:

    use DBIx::Class::QueryLog;

	my $schema = ... # Get your schema!
    my $ql = new DBIx::Class::QueryLog();
	$schema->storage->debugobj($ql);
	$schema->storage->debug(1);
    ... # do some stuff!

Every transaction and query executed will have a corresponding Transaction and Query object stored in order of execution, like so:

Query
Query
Transaction
Query

This array can be retrieved with the log() method. Queries executed inside a transaction are stored inside their Transaction object, not inside the QueryLog directly.

See DBIx::Class::QueryLog::Analyzer for options on digesting the results of a QueryLog session.
