tracker3-sql - Use SQL to query the Tracker databases.

       This command allows probing of the current database. When using commands like tracker3sparql, the SPARQL
       used is translated into SQL before being run on the database. This allows direct use of the database
       using SQL avoiding the SPARQL engine entirely.

       The caller can run a query two ways, either by providing a file with the query or by providing a string
       with the sql query.

       The file argument can be either a local path or a URI. It also does not have to be an absolute path.

       Show first 10 "nfo:Document" entries where the TOC is not NULL

               $ tracker3 sql -q 'SELECT * FROM "nfo:Document" WHERE "nfo:tableOfContents" NOT NULL LIMIT 10;'

-f,--file=<file>
           Use a file with SPARQL content to query. Don’t forget to end all queries with a semicolon (;) and
           also to use quotes around table names. The quotes are important because most tables are named after
           ontology classes like "nfo:Document" and queries will fail without the quotes.

       -q,--query=<sql>
           Use a sql string to query the database with.
