2. Snippet objectives
● Set up a spreadsheet for use as a database
● Demonstrate Read/write/delete updating
Libraries used
● database abstraction
● driver sheet

3. Add libraries to script

4. layout what you are going to do
function myFunction() {
// open spreadsheet as database
// do a query
// add a new record
// do a query and sort and limit
// delete added record
// count query
}

5. Get a handler for the sheet
https://docs.google.com/spreadsheets/d/14xvwnQwhvw4jSGRBo7ZbJvNaNu438-5mMl2u_TJswlw/edit?usp=sharing
// open spreadsheet as database
var handler = new cDbAbstraction.DbAbstraction (cDriverSheet, {
siloid:'carrierCodes',
dbid:'14xvwnQwhvw4jSGRBo7ZbJvNaNu438-5mMl2u_TJswlw',
});
if (!handler.isHappy()) throw 'unable to open sheet';

6. Do a query
// do a query
var result = handler.query ({carrier:'UA'});
if (result.handleCode < 0) throw result.handleError;
Logger.log(result.data);
result...
[{name=United Airlines, carrier=UA}]

7. Add something and query
// add a new record
var result = handler.save ({carrier:'xx',name:'Dodgy Air'});
if (result.handleCode < 0) throw result.handleError;
// do a query and sort and limit
var result = handler.query ({},{sort:'-carrier',limit:5});
if (result.handleCode < 0) throw result.handleError;
Logger.log(result.data);
result...
[{name=Dodgy Air, carrier=xx},
{name=Great Lakes Airlines, carrier=ZK},
{name=Great Lakes Airlines, carrier=ZK},
{name=Shenzhen Airlines, carrier=ZH},
{name=Monarch Airways, carrier=ZB}]

8. delete and count
// delete added record
var result = handler.remove ({name:'Dodgy Air'});
if (result.handleCode < 0) throw result.handleError;
// count query
var result = handler.count ();
if (result.handleCode < 0) throw result.handleError;
Logger.log(result.data);
result...
[{count=199.0}]
