OK... misinterpreted. I thought that NULL AS '' means ,'',[1] so that empty strings could be imported as NULL if necessary and as empty string if not. So at my understanding there is no way to use \copy and insert NULL when it encounter an empty string and NULL AS '' doesn't do anything in CSV mode since when I have ,, it actually imports NULL and when I have ,'', it imports empty strings that is the same behaviour I get without NULL AS ''. Correct? If it is I found the documentation a bit misleading. I admit it could be due to not being English mother tongue. thx [1] I did try with "''", '""', '\"\"'... -- Ivan Sergio Borgonovo http://www.webthatworks.it ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
