I need to get some information in database and export it.
Is there a way to make PostgreSQL to export one data line to a new file?
Like this:
1 FIRST LINE --> line1.txt;
2 SECOND LINE --> line2.txt;
3 THIRD LINE --> line3.txt
...
and so...
I know that I can import all information into a unique file, but I need to
split that information into severel files.
I've already searched in everything and didn't find a solution.
Can anybody help?
Thanks in advance.
I doubt it. You should export to a single file then use another tool to
perform the split. What platform and you working on? If its Linux using
"psql | some_splitting_command" should be doable.
I guess you put your query into a function and use procedural language
functionality to do that but I'm not sure on the necessary syntax.
There may be third-party ETL tools that fulfill this need as well.
One I recently ran across is Dataset:
https://github.com/pudo/dataset
Docs:
https://dataset.readthedocs.org/en/latest/
In particular freezefile:
https://dataset.readthedocs.org/en/latest/freezefile.html
"mode specifies whether the query output is to be combined into a single
file (list) or whether a file should be generated for each result row
(item)."
