Important

Self-managed SingleStore will soon transition from version 9.1 RC to version 10. This new semantic versioning scheme will provide SingleStore with finer control over engine and feature releases that were not possible with the current versioning scheme.

In the interim, SingleStore 9.1 RC can be used to preview, evaluate, and provide feedback on the new and upcoming features in SingleStore 10 prior to its general availability. Ahead of this transition, SingleStore 9.0 is recommended for production workloads, which can later be upgraded to SingleStore 10.

BSON_GET_TYPE

Syntax

BSON_GET_TYPE(<input>)

Argument

<input>: A valid BSON value or an expression that evaluates to a valid BSON value.

If the input is an invalid BSON value, returns "missing" as the result.
