i have query similair to this

SELECT p.*
FROM products p
WHERE p.createdAt = [[ {{dateOfCreation}} #]]CURRENT_DATE

which works when I don’t input any value for dateOfCreation parameter but when I input a value, it fails
error below

ERROR: operator does not exist: date # date Hint: No operator matches the given name and argument types. You might need to add explicit type casts. Position: 1219

Hi @anonymous

  1. Post “Diagnostic Info” from Admin > Troubleshooting.
  2. Which database are you querying?
  3. Post your query

For reference, not all database uses # as comment syntax: https://www.metabase.com/docs/latest/users-guide/13-sql-parameters.html#default-value-in-the-query

database is postgres
query =

select * from
FROM _schedule 
where _schedule.created_at::date >= {{start_date}}  
and _schedule.created_at::date <= [[ {{end_date}} #]]CURRENT_DATE

if I get this right, meaning I will have to replace # with --, like shown below

select * from
FROM _schedule 
where _schedule.created_at::date >= {{start_date}}  
and _schedule.created_at::date <= [[ {{end_date}} --]]CURRENT_DATE

@anonymous Postgres uses -- as comment syntax:
