toUInt() function

toUInt() converts all values in the _value column to unsigned integer types.

Supported types and behaviors

toUInt() behavior depends on the _value column type:

_value type Returned value
string UInteger equivalent of the numeric string
bool 1 (true) or 0 (false)
duration Number of nanoseconds in the specified duration
time Equivalent nanosecond epoch timestamp
float Value truncated at the decimal
int UInteger equivalent of the integer
Function type signature
(<-tables: stream[{A with _value: B}]) => stream[{A with _value: B, _value: uint}]

For more information, see Function type signatures.

Parameters

tables

Input data. Default is piped-forward data (<-).

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.
