If you choose to reuse employee you might want to scrub away the bad data later. It also is not clear to me why you are inserting back into the employee table which has non usable data, rather than inserting into a new table. This assumes that your timestamp data is formatted as follows: DD/MM/YYYY HH:MI:SS PM (e.g. Select 14, coalesce(to_timestamp(dojo, 'DD/MM/YYYY HH:MI:SS PM'), current_timestamp) Something like the following is what I believe you intend to do: insert into employee (eid, dojo) Instead, you should be using to_timestamp(), which can parse a string and return a timestamp. The output of to_char is a string, and the way you are using it would cause Postgres to reject it. As others have pointed out, one solution would be to use current_timestamp as a placeholder.Īnother problem you have is that you are incorrectly using to_char to format your timestamp data. This won't work, because empty string is not a valid timestamp. First, you are trying to insert an empty string '' to handle NULL values in the dojo column. Your current query has severals problems, two of which I think my answer can resolve. How do I skip an item in while loop if variable empty?.
