__DATA__
- sql: |
CREATE TABLE actors (

# In your code somewhere else
use SQL::DB;
use SQL::DBx::Deploy;
my $db = SQL::DB->connect('dbi:SQLite:dbname=test');
# The '::Deploy::SQLite' part is auto appended
$db->deploy('MyApp');
# Multiple calls are safe
$db->deploy('MyApp');DESCRIPTION
SQL::DBx::Deploy adds deployment support to SQL::DB. Your SQL and Perl statements (formatted as YAML) are included in the __DATA__ section of a Perl module. Calls to deploy() will load that module and run any statements contained inside that have not already been applied to the database. SQL::DBx::Deploy keeps track of what has been run through a table in your database called '_deploy'.
Note that the approach is very simple, based on the number of statements already executed. You can only ever add new statements to your deploy module.
METHODS
- deploy($app)
-
Deploy the YAML found in the __DATA__ section of the $app::Deploy::$driver module.
- last_deploy_id( $app )
-
Returns the count of all deployment statements.
