NAME

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

SYNOPSIS

       tracker3 sql -q <sql> | -f <file>

DESCRIPTION

       This command allows probing of the current database. When using commands like tracker3
       sparql, 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.

OPTIONS

       -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.

EXAMPLES

       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;'
