Altova XMLSpy 2024 Enterprise Edition

Given below are the steps to establish a connection to an existing database for import:

1.Use a DatabaseConnection object and set the following:

•The method Application.GetDatabaseSettings returns a new object for a database connection: objImpSettings = objSpy.GetDatabaseSettings();  

•You have to set either an ADO connection string, objImpSettings.ADOConnection = strADOConnection or the path to an existing database file: objImpSettings.File = strExampleFolder + "Tutorial\\Company.mdb";

•To complete the settings you create an SQL SELECT statement to define the data to be queried: objImpSettings.SQLSelect = "SELECT * FROM Address";

2.Call Application.GetDatabaseImportElementList to get a collection of the resulting columns of the SQL query: objElementList = objSpy.GetDatabaseImportElementList(objImpSettings); This collection gives you the opportunity to control which columns should be imported and specify the datatype of the new elements. Each item of the collection represents one column to import. If you remove an item, the corresponding column will not be imported. You can additionally modify the ElementListItem.ElementKind property to set the datatype of the XML elements for each column. Please consider that GetDatabaseImportElementList() executes the SQL query and could initiate a time-consuming call. To avoid this, it is possible to pass a null-pointer as the second parameter to ImportFromDatabase(); this imports all columns as plain XML elements.

3.Start the import with Application.ImportFromDatabase: objImpDocFromDB = objSpy.ImportFromDatabase(objImpSettings,objElementList);

The JScript code listed above is available in the sample file ImportExport.js (see Example Files).
