• Database name: The name of the database to query. Provide this using one of the following:

  • -d, --database command option
  • INFLUXDB3_DATABASE_NAME environment variable

• Query language (Optional): The query language of the query. Use the -l, --language option to specify one of the following query languages:

  • sql (default)
  • influxql

• Query: SQL or InfluxQL query string to execute.

influxdb3 query \
  --database 
DATABASE_NAME
 \
  "SELECT * FROM home"

influxdb3 query \
  --database 
DATABASE_NAME
 \
  --language influxql \
  "SELECT * FROM home"

In the examples above and below, replace the following:

• DATABASE_NAME: Name of the database to query

Output format

The influxdb3 query command supports the following output formats:

• pretty (default)
• json
• jsonl
