sorry, corrected below:

1 select *
2 from table
3 if '$sanitized_variable' = '' then -- $variable not provided or
undefined or empty,
4 where true -- so select every row/record
5 else
6 where input = '$sanitized_variable' -- variable provided or defined
or not-empty, so select only matching rows/records where input is a
column/field
7 end if;
