Do InfluxQL mathematical operators support string constants?

When I was reviewing the InfluxDB documentation, I noticed the mention of “Perform addition with a constant.” in the context of addition operations. Therefore, I want to confirm whether InfluxQL mathematical operators support string constants. I tried executing it in the backend Influx v1 shell, but it doesn’t seem to include this functionality. For example, the following query,
select * from table where 'A' < 'B'
In that case, A and B are ordinary strings and not values from any column in the table. but influxdb returns no results.
Any assistance would be greatly appreciated!
