man Alzabo::Schema () - Schema objects
NAME
Alzabo::Schema - Schema objects
SYNOPSIS
use base qw(Alzabo::Schema);
DESCRIPTION
This is the base class for schema objects..
METHODS
name
Returns a string containing the name of the schema.
table ($name)
Returns an CWAlzabo::Table object representing the specified table.
An CWAlzabo::Exception::Params exception is throws if the schema does not contain the table.
tables (@optional_list)
If no arguments are given, this method returns a list of all CWAlzabo::Table objects in the schema, or in a scalar context the number of such tables. If one or more arguments are given, returns a list of table objects with those names, in the same order given (or the number of such tables in a scalar context, but this isn't terribly useful).
An CWAlzabo::Exception::Params exception is throws if the schema does not contain one or more of the specified tables.
has_table ($name)
Returns a boolean value indicating whether the table exists in the schema.
begin_work
Starts a transaction. Calls to this function may be nested and it will be handled properly.
rollback
Rollback a transaction.
commit
Finishes a transaction with a commit. If you make multiple calls to CWbegin_work(), make sure to call this method the same number of times.
run_in_transaction ( sub { code... } )
This method takes a subroutine reference and wraps it in a transaction.
It will preserve the context of the caller and returns whatever the wrapped code would have returned.
driver
Returns the CWAlzabo::Driver object for the schema.
rules
Returns the CWAlzabo::RDBMSRules object for the schema.
sqlmaker
Returns the CWAlzabo::SQLMaker object for the schema.
