SQL hashing functions

Use hashing functions to hash string values in SQL queries using established hashing algorithms.

digest

Computes the binary hash of an expression using the specified algorithm.

digest(expression, algorithm)

Arguments

  • expression: String expression to operate on. Can be a constant, column, or function, and any combination of operators.

  • algorithm: String expression specifying algorithm to use. Must be one of the following:

    • md5
    • sha224
    • sha256
    • sha384
    • sha512
    • blake2s
    • blake2b
    • blake3

md5

Computes an MD5 128-bit checksum for a string expression.

md5(expression)

Arguments

  • expression: String expression to operate on. Can be a constant, column, or function, and any combination of operators.

sha224

Computes the SHA-224 hash of a binary string.

sha224(expression)

Arguments

  • expression: String expression to operate on. Can be a constant, column, or function, and any combination of operators.

sha256

Computes the SHA-256 hash of a binary string.

sha256(expression)

Arguments

  • expression: String expression to operate on. Can be a constant, column, or function, and any combination of operators.

sha384

Computes the SHA-384 hash of a binary string.

sha384(expression)

Arguments

  • expression: String expression to operate on. Can be a constant, column, or function, and any combination of operators.

View sha384 query example

sha512

Computes the SHA-512 hash of a binary string.

sha512(expression)

Arguments

  • expression: String expression to operate on. Can be a constant, column, or function, and any combination of operators.

New in InfluxDB 3.5

Key enhancements in InfluxDB 3.5 and the InfluxDB 3 Explorer 1.3.

See the Blog Post

InfluxDB 3.5 is now available for both Core and Enterprise, introducing custom plugin repository support, enhanced operational visibility with queryable CLI parameters and manual node management, stronger security controls, and general performance improvements.

InfluxDB 3 Explorer 1.3 brings powerful new capabilities including Dashboards (beta) for saving and organizing your favorite queries, and cache querying for instant access to Last Value and Distinct Value caches—making Explorer a more comprehensive workspace for time series monitoring and analysis.

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On November 3, 2025, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
