I have this file (warning: potentially unsafe file download site) that I need to insert into the database using Postgres and Java. Please download it and let me know how I can extract data from this file. I tried the copy command. For one, it did not let me use the header option. I have to, as you can see from the file, copy data from the 4th row onwards. Another thing is the delimiter. If you read the file in notepad++, you can see them as proper columns, but there is no delimiter as such. I have tried and faced these challenges. Please help me get a custom query. Or another approach that can achieve what I want to do. Thanks!
Edit: I have used a safer link to download the file. Hope it works.
So it sounds like you are doing fixed width files. COPY doesn't handle these so your best bet is to load up a spreadsheet, import the file (most can handle fixed width), and then export as csv. You can then use COPY.
