This is not practical. It stopped and is replaced by the IndexedDB API . In the end, the web SQL database will be deleted from the browsers that currently support it.
You might like the current browser support data for Web SQL Database and IndexedDB . There are more browsers in the Web SQL database that currently support it, but Firefox does not support it and outweighs Safari, Opera and various mobile browsers, and therefore it is only about 28%, and IndexedDB is almost 36% of global support. In addition, I believe that it is generally believed that Microsoft will support IndexedDB in IE10, while the Web SQL database API will no longer go.
Update, 2013-02-04: IE10 supports IndexedDB; Web SQL and IndexedDB support just under 50%. Compliance with the IndexedDB specification is also very good, which has led IE10, Firefox and Chrome to now support it unchanged.
