current_date is give search result with a timestamp column in postgres

Question

I have a column of type varchar which stores date with timestamp, and without timestamp in postgres. While trying to hit the below query,

select * from table where cast(column as date) = CURRENT_DATE::date

it is returning those columns also which has date with timestamp also. How can I modify the query to find the exact match of only dates and not with timestamp.

sample input data:

Column1
2022-12-09 17:38:53.415367
2022-12-09

Expected output:

2022-12-09

Actual: getting both the columns in the result

2022-12-09 17:38:53.415367
2022-12-09

Answer 1

Per my comment:

SELECT
    t.dt_val
FROM (
    VALUES ('2022-12-09'),
        ('2022-12-09 17:38:53.415367')) AS t (dt_val)
WHERE
    t.dt_val::timestamp = '2022-12-09'::date + '00:00:00'::time;

 dt_val   
------------
 2022-12-09

I used '2022-12-09'::date instead of current_date to make the answer relevant in the future. At time of answer current_date resolves to '2022-12-09'::date .
