Other query:
cbs_get_data()

# useful substrings:
## Periods: "JJ": years, "KW": quarters, "MM", months
## Regions: "NL", "PV": provinces, "GM": municipalities
cbs_get_data( id = "7196ENG" # table id
, Periods = has_substring("JJ") # all years

, Periods = c("2000MM03","2001MM12") # March 2000 and Dec 2001
, CPI = "000000" # Category code for total

# combine either this
cbs_get_data( id = "7196ENG" # table id
, Periods = has_substring("JJ") | "2000MM01" # all years and Jan 2001
, CPI = "000000" # Category code for total

# or this: note the "eq" function
cbs_get_data( id = "7196ENG" # table id
, Periods = eq("2000MM01") | has_substring("JJ") # Jan 2000 and all years
, CPI = "000000" # Category code for total
