使用postgres脚本从JAVA导入CSV

Question

So I have this script that i need to execute from a Java web application. The file containing this lines is located under WEB-INF

    truncate table amm.mm_dosage_unit;
    alter table amm.mm_dosage_unit add column code_new_version character varying(1);
    copy amm.mm_dosage_unit FROM 'code_list.csv' DELIMITER ',' CSV;

I use reader to execute each of the lines. Problem is that I dont know how to scpecifie the correct path for my .csv file and i get No such file or directory error.

Any ideas

Answer 1

To my understanding, the SQL query is running on the server, which is a separate filesystem to the client running the web application.

The sql server would be looking for a file on the server, while the CSV file is actually located on the client's machine.
