I have a syntax, but it doesn't work.
Here is my query:
SELECT *
FROM aqua.reading
WHERE
CAST(reading.pres_date AS VARCHAR)
BETWEEN LIKE '2022-10-18%' AND LIKE '2022-10-18%'
it says:
ERROR: type "like" does not exist
LINE 1: ... WHERE CAST(reading.pres_date AS VARCHAR) BETWEEN LIKE '2022...
^
SQL state: 42704
Character: 77
I am trying to get all the data with timestamp and timezone and implement a date range
Don't compare dates (or timestamps) as strings. Compare them to proper date (or timestamp) values. Given the fact that you use the same "date" but with a wildcard at the end, I am assuming(!) that pres_date is in fact a timestamp column and you want to find all rows with a given date regardless of the time value of the timestamp.
The best approach is to use a range query with >= ("greater than or equal) on the lower value and < (strictly lower than) on the next day:
SELECT *
FROM aqua.reading
WHERE reading.pres_date >= DATE '2022-10-18'
AND reading.pres_date < DATE '2022-10-19'
Alternatively you can cast the timestamp to a date and use the = operator if you really want to pick just one day:
SELECT *
FROM aqua.reading
WHERE cast(reading.pres_date as DATE) = DATE '2022-10-18'
However that will not make use of a potential index on pres_date so is likely to be slower than the range query from the first solution
%from your two dates and just use BETWEEN.WHERE reading.pres_date BETWEEN '2022-10-18' AND '2022-10-18'BETWEEN .. AND .., when beginning and ending dates are the same, makes no sense.... WHERE reading.pres_date = '2022-10-18'. Assumingreading.pres_dateis actually adatetype value.
