Here’s the SQL variant of the hyperlink-enhanced SPARQL Cheatsheet 
generated by ChatGPT.


      Testing ANSI SQL Query Examples

    Q: Redo, using these guidelines, for the first 3 rows:

     1.

        Set the Virtuoso SPASQL Query Service URL to https:
        //demo.openlinksw.com/spasqlqb/

     2.

        Qualify Table Names portion of the quoted values in “Example”
        column by adding Demo.Demo (representing Database and Schema
        respectively)

     3.

        Use “Example” column values within quotations as values of for
        “sql” key in the JSON structure that follows
        {
        “v”: 1,
        “url”: “/XMLA”,
        “dsn”: “DSN=Local_Instance”,
        “uid”: “demo”,
        “pwd”: “demo”,
        “path”: null,
        “tab”: “exec”,
        “idx”: null,
        “fkey”: null,
        “ref”: null,
        “exec”: {
        “sql”: “SELECT ProductName FROM Demo..Products WHERE CategoryID
        = 1 UNION SELECT ProductName FROM Demo..Products WHERE
        CategoryID = 2\n”
        }
        }

     4.

        Create an encoded Virtuoso SPASQL Query Service URL using JSON
        structure as the value for the ?permlink_e parameter

     5.

        Use the constructed Virtuoso SPASQL Query Service URL to
        hyperlink values in the “Command” Column

     6.
