toInt() function
The toInt()
function converts all values in the _value
column to integers.
Function type: Type conversion
toInt()
Supported data types: Boolean | Duration | Float | Numeric String | Time | Uinteger
For duration and time values, toInt()
returns the following:
Input type | Returned value |
---|---|
Duration | The number of nanoseconds in the specified duration |
Time | A nanosecond epoch timestamp |
To convert values in a column other than _value
, define a custom function
patterned after the function definition,
but replace _value
with your desired column.
