When I used SQL identifier, it stopped working. The command line gets interpreted as following:
insert into stats select "1" as id, 'count of nulls in "UNIQUE_REFERENCE_NUMBER"' as checks, count("""UNIQUE_REFERENCE_NUMBER""") from points_of_interest."pointx_v2_National_Coverage_Sep21" where """UNIQUE_REFERENCE_NUMBER""" is null
I used select count("UNIQUE_REFERENCE_NUMBER") from a_table where "UNIQUE_REFERENCE_NUMBER" is null in SQL.
It always worked.
This can not be replicated in Execute Format.

How to ensure that the columns are double-quote when they are fed in as variables.Quoting the relevant doc section:type (required)The type of format conversion to use to produce the format specifier's output. The following types are supported:
s formats the argument value as a simple string. A null value is treated as an empty string.
I treats the argument value as an SQL identifier, double-quoting it if necessary. It is an error for the value to be null (equivalent to quote_ident).
L quotes the argument value as an SQL literal. A null value is displayed as the string NULL, without quotes (equivalent to quote_nullable).David J.
