Returns a list of SQL statements to alter this table so that it is identical
to the provided table, also a DBIx::DBSchema::Table object.
- #Optionally, the data source can be specified by passing an open DBI database
- #handle, or by passing the DBI data source name, username and password.
- #
- #If passed a DBI data source (or handle) such as `DBI:Pg:dbname=database', will
- #use PostgreSQL-specific syntax. Non-standard syntax for other engines (if
- #applicable) may also be supported in the future.
- #
- #If not passed a data source (or handle), or if there is no driver for the
- #specified database, will attempt to use generic SQL syntax.
+The data source can be specified by passing an open DBI database handle, or by
+passing the DBI data source name, username and password.
+
+Although the username and password are optional, it is best to call this method
+with a database handle or data source including a valid username and password -
+a DBI connection will be opened and used to check the database version as well
+as for more reliable quoting and type mapping. Note that the database
+connection will be used passively, B<not> to actually run the CREATE
+statements.
+
+If passed a DBI data source (or handle) such as `DBI:mysql:database' or
+`DBI:Pg:dbname=database', will use syntax specific to that database engine.
+Currently supported databases are MySQL and PostgreSQL.
+
+If not passed a data source (or handle), or if there is no driver for the
+specified database, will attempt to use generic SQL syntax.
