Example
If you are using Database abstraction with google apps script, changing back ends is easy. Let’s say you are using scriptDB, but want to migrate your data to Datastore it’s pretty straightforward. Your applications won’t need to change much since your queries will all have been abstracted. Here’s how to copy over. We’re using DataStore so we need an Oauth2 pattern and your datastore setup as described in Datastore driver
function conversionFromScriptDB () { return doGetPattern({} , constructConsentScreen, scriptDBCopyToDataStore,'googleDatastore'); } function scriptDBCopyToDataStore (accessToken) { //get some data from - no Siloid in original data var handler = new cDataHandler.DataHandler ( '', cDataHandler.dhConstants.DB.SCRIPTDB, undefined, 'myddb', ScriptDb.getMyDb(), undefined, true, 'bruce', undefined, true); assert(handler.isHappy(), 'unable to get scriptdb handler','handler'); // get a datastore handler var dsHandler = new cDataHandler.DataHandler ( 'crap', // Kind cDataHandler.dhConstants.DB.DATASTORE, // Datastore undefined, 'xliberationdatastore', // project id undefined, undefined, true, // analytics opt out 'bruce', // analytics debugging tracking accessToken, // the access token true); // disable caching for testing assert(dsHandler.isHappy(), 'unable to get scriptdb handler','handler'); // do the copy var data = handler.query(); assert (data.handleCode >=0, data, 'getting data from script'); // delete everything in current datastore var result = dsHandler.remove(); assert (result.handleCode >=0, result, 'deleting data from datastore'); // copy it to datastore var result = dsHandler.save(data.data); assert (result.handleCode >=0, result, 'writing data to datastore'); // read it back and make sure it all made it var result = dsHandler.query(); assert (result.handleCode >=0, result, 'querying data from datastore'); }
