_id column is created as a primary key for each table. In the example below, you can see the structure of an XMLВ file containing three value nodes for Address: JOIN person ON address.Person_id = Person._id The query could include the following SQL statement: To query the content you have loaded into the caching database through SQL, use the foreign key in the child table to join the child table with the parent table, for instance. If it is present, but has no text, it has an empty value. If the value node is missing in one of the occurrences of its parent, the value is NULL. You can also provide a second (optional) argument to specify the object or array to extract. To use this function, you provide the JSON expression as an argument. If you specify an XPath, the result is wrapped inside an artificial root, called Entity to make it a valid XML. When using JSON with SQL Server, you can use the JSONQUERY() function to extract an object or an array from a JSON string. If a tag appears in different places under n different parents, it has foreign key columns in the following format: _id format for primary key. If a value node appears more than once in its parent or has an attribute, it will have its own table. JSON/XML File Load into Caching Database Module in a TestStep Logic for creating tablesДЄfter loading an XML file into the caching database, the content of the file is being converted into a table in the following manner:Д®very node inВ the file that has child nodes, is being converted into a table.ДЄll child nodes that are value nodes, become columns in the parent table.

This prefix is used for all tables created. To avoid overwriting existing tables with the same name, specify a table prefix. If you define XPath, namespaces are not supported. You can define the JPath/XPath, if you have a large file and want to filter out specific subnodes of the file. The supported formats are JSON and XML.Дefine the JPath or XPath expression to navigate through elements and attributes in an XMLВ or JSON file.

The JSON/XML File Load into Caching Database Module contains the following attributes:Д®nter the full file path and file name of the JSON or XML file you want to load.Дefine the file format of your file. It gives flexibility to the developers to convert the result to JSON. JSON/XML File Load into Caching Database Module Sql Server 2016 FOR JSON clause can be used to convert the query result to JSON format. This allows you to run all sorts of standard tests of Tosca DI, including Metadata field tests and Row by Row Comparison.Д¬onfigure the path of the SQLite caching database in the Settings dialog in Tosca Commander ( see chapter 'Settings - Tosca Data Integrity'). To assist in the above mentioned use case and provide full flexibility, the content is loaded into a database that you can query through SQL. how many records are present in general or how many records of a certain type are present. To verify the content in a JSON or XML file, e.g. Typical use cases for this functionality are: Use the JSON/XML File Load into Caching Database Module to load a JSON or XMLВ file into an SQLite database.
