iox.sqlInterval() function

iox.sqlInterval() is experimental and subject to change at any time.

iox.sqlInterval() converts a duration value to a SQL interval string.

Duration values must be positive to work as a SQL interval string.

Function type signature
(d: A) => string

For more information, see Function type signatures.

Parameters

d

(Required) Duration value to convert to SQL interval string.

Examples

Convert a duration to a SQL interval

import "experimental/iox"

iox.sqlInterval(
    d: 1y2mo3w4d5h6m7s8ms,
)// Returns 1 years 2 months 3 weeks 4 days 5 hours 6 minutes 7 seconds 8 milliseconds

Use a Flux duration to define a SQL interval

import "experimental/iox"

windowInterval = 1d12h
sqlQuery = "
SELECT
  DATE_BIN(INTERVAL '${iox.sqlInterval(
        d: windowInterval,
    )}', time, TIMESTAMP '2023-01-01T00:00:00Z') AS time_bin,
  COUNT(field1)
FROM
  measurement
GROUP BY
  time_bin
"

iox.sql(bucket: "example-bucket", query: sqlQuery)

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
