Updating typed datasets

The available data types are listed in section Data Types. Adding an item will fail when there already is an item with the same id. Data Set(); // subscribe to any change in the Data Set data.on('*', function (event, properties, sender Id) ); // add an item data.add(); // triggers an 'add' event data.update(); // triggers an 'update' event data.remove(1); // triggers an 'remove' event is provided, this id will be passed with the triggered event to all subscribers.The function returns an array with the ids of the added items. The method will throw an Error when an item with the same id as any of the added items already exists. Syntax: The method ignores removal of non-existing items, and returns an array containing the ids of the items which are actually removed from the Data Set.Item properties can be normalized by specifying a field type.This is useful for example to automatically convert stringified dates coming from a server into Java Script Date objects.Bind variables are placeholders inside a SQL statement.When a database receives a SQL statement, it determines if the statement has already been executed and stored in memory.

Data Set(options); // add items // note that the data items can contain different properties and data formats data.add([ , , , ]); // subscribe to any change in the Data Set data.on('*', function (event, properties, sender Id) ); // update an existing item data.update(); // remove an item data.remove(4); // get all ids var ids = Ids(); console.log('ids', ids); // get a specific item var item1 = data.get(1); console.log('item1', item1); // retrieve a filtered subset of the data var items = data.get(); console.log('filtered items', items); // retrieve formatted items var items = data.get(); console.log('formatted items', items); The name of the field containing the id of the items.

By using CKAN’s IDataset Form plugin interface, a CKAN plugin can add custom, first-class metadata fields to CKAN datasets, and can do custom validation of these fields.

When a dataset is created, updated or viewed, the parameters passed to CKAN (e.g.

If the statement does exist in memory, Oracle Database can reuse it and skip the task of parsing and optimizing the statement.

Using bind variables makes the statement reusable with different input values.
