From 7b2a6f04443c5d80ce681e5f1c89bf140fdb5c3a Mon Sep 17 00:00:00 2001 From: Jean-Pierre Ledure Date: Sat, 11 Nov 2023 17:02:38 +0100 Subject: [PATCH] ScriptForge (SFDatabases) new Dataset service A dataset represents a set of tabular data stored/produced by a database. To use datasets, the database instance must exist but the Base document may not be open. A Dataset instance is create either with - the (new) database.CreateDataset() method - from an existing dataset with the (new) dataset.CreateDataset() method. The proposed API supports next main purposes: - browse for- and backward thru the dataset to get its content - update any record with new values - create new records or delete some. In summary, the AKA "CRUD" operations (create, read, update, delete). The originality of the proposed API is the use of a dense syntax to make insertions and updates easy and readable: Example: (BASIC) Dim newID As Long newID = dataset.Insert("LastName", "Doe", "FirstName", "John") ' ... is equivalent to: Dim dict As Object, newID As Long Set dict = CreateScriptService("ScriptForge.Dictionary") dict.Add("LastName", "Doe") dict.Add("FirstName", "John") newID = dataset.Insert(dict) (PYTHON) - next statements are equivalent newid = dataset.Insert('LastName', 'Doe', 'FirstName', 'John') newid = dataset.Insert({'LastName': 'Doe', 'FirstName': 'John'}) newid = dataset.Insert(dict(LastName = 'Doe', FirstName = 'John')) newid = dataset.Insert(LastName = 'Doe', FirstName = 'John') You will notice that the returned value is the AutoValue primery key (when it exists) which makes it reuse as a foreign key immediate. The API is fully available both in Basic and Python user scripts. The new service will require its inclusion in the user documentation.
