The transaction is simply a function that contains some code: Web SQL database rollback demo In the nightly builds of the browsers, we also have db. Once we have a transaction object, we can call executeSql: What if we want to capture the text from the user or some external source?
The second argument to executeSql maps field data to the query, like so: Finally, if we want to select values from the table, we use a callback to capture the results: The callback receives the transaction object again and the results object.
