sqldf with label attached to a variable does not work

[spal2024]

I am a fan of sqldf when it comes to data wrangling as I came from SAS background. However I have noticed when a variable has a label attached to it, we could not use sqldf. We get the error message as 'Error in match.fun(asfn) :
'c("as.labelled", "as.Date")' is not a function, character or symbol' I think it's a known issue. The way I am dealing with this situation is creating a brand new variable without a label using mutate function and feed those columns into sqldf. Is there any alternative way you guys suggest?

There isn't enough detail in the question to address this but maybe the method= argument of sqldf can be used.
