TRACKER3-SQL(1) Tracker manual TRACKER3-SQL(1)
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;'
