Workflow::Persister::DBI::AutoGeneratedId - Pull IDs from databases that autogenerate them
This documentation describes version 1.06 of this package
<persister name="MyPersister" dsn="DBI:mysql:database=foo" ...
Be able to pull an ID from a database or statement handle, or call a DBI function to get the value.
If you want to pull the value from a handle specify either 'database' or 'statement' to specify what handle to pull it from. You must also specify a value for 'handle_property'. For example, if you are using MySQL this would be 'database'.
Property to pull from handle specified in 'from_handle'. For example, if you are using MySQL this would be 'mysql_insertid'.
Property to pass to the DBI 'func()' call to return the ID value. For example, if you are using SQLite this would be 'last_insert_rowid'.
This method instantiates a class for retrieval of auto-generated ids from a DBI based persistance entity.
It takes a hashref containing keys matching the properties outlines in the section above or throws Workflow::Exceptions if these are not defined.
Returns instantiated object upon success.
This is a dummy method, use "post_fetch_id"
Returns a unique sequence id from a database.
Takes a two parameters, a DBI database handle and a statement handle
Returns a single value, a integer representing a sequence id from the provided database handle, based on the statement handle.
