NAME
       tracker-sql - Use SQL to query the Tracker databases.


SYNOPSIS
       tracker sql -q  | -f 


DESCRIPTION
       This  command  allows  probing of the current database. When using com‐
       mands like tracker sparql, the  SPARQL  used  is  translated  into  SQL
       before  being  run on the database. This allows direct use of the data‐
       base 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.


OPTIONS
       -f, 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=
              Use a sql string to query the database with.


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

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