postgre sql search in table with type timestamp without timezone

Question

I need to search all columns in postgre sql table using a string.But it causes error for column with type "timestamp without timezone"; It shows the error:"ERROR: operator does not exist: timestamp without time zone ~~ unknown"

Answer 1

You are trying to search a timestamp using the LIKE operator (internally ~~ ). That cannot work, because that operator does not exist for datetime data types.

You will have to cast the timestamp to a string data type:

WHERE CAST(timestamp_col AS text) LIKE '2021-%'

or, better, explicitly format it as string:

WHERE to_char(timestamp_col, 'YYYY-MM-DD HH24:MI:SS') LIKE '2021-%'
