typeof

Description

Print the underlying Go type of the variable.

You can use any argument name. So typeof(x=my_var) and typeof(fluffydinosaur=my_var) are equivalent.

Only the first argument provided will be evaluated and returned.

Examples

SELECT typeof(x=1) AS Type FROM scope()

returns: Type: int64

LET my_time <= timestamp(epoch="2024-03-26T06:53:37Z")
SELECT typeof(thing=my_time) AS Type FROM scope()

returns: Type: time.Time

Notes

The typeof function is a more concise alternative to using the more flexible and more powerful format function:

SELECT format(format="%T", args=x) AS Type FROM scope()

The typeof function is often used to inspect the data type of returned values when writing and testing VQL.

It is also useful as a row filter by including it in the WHERE clause of a query to ensure that a specific column does not contain values of an unexpected data type.
