I am working with an Oracle database – the only way I have to access it is through SQL Developer. Part of my work involves exporting large tables to csv files to pass to another group. Since this is mostly babysitting the system, I’ve been looking for a way to automate the export process.
What I would like is to have a procedure like so:
PROCEDURE_EXAMPLE(table_in in VARCHAR2, file_out in VARCHAR2)
where table_in is the table I need to export, and it exports the table to a series of csv files titled “file_out_1.csv” “file_out_2.csv”, etc.. each with no more than 5 million rows.
Is it possible to create a procedure like this?
You can using the UTL_FILE package. You can only read files that are accessible from the server on which your database instance is running.
