Working with local SQL databases in AIR
Retrieving a database-generated primary key of an inserted row
Adobe AIR 1.0 and later
Often after inserting a row of data into a table, your code needs to know a database-generated primary key or row
identifier value for the newly inserted row. For example, once you insert a row in one table, you might want to add
rows in a related table. In that case you would want to insert the primary key value as a foreign key in the related table.
The primary key of a newly inserted row can be retrieved using the SQLResult object associated with the statement
execution. This is the same object that’s used to access result data after a SELECT statement is executed. As with any
SQL statement, when the execution of an INSERT statement completes the runtime creates a SQLResult instance. You
access the SQLResult instance by calling the SQLStatement object’s getResult() method if you’re using an event
listener or if you’re using synchronous execution mode. Alternatively, if you’re using asynchronous execution mode
and you pass a Responder instance to the execute() call, the SQLResult instance is passed as an argument to the result
handler function. In any case, the SQLResult instance has a property, lastInsertRowID, that contains the row
identifier of the most-recently inserted row if the executed SQL statement is an INSERT statement.
