Postgres Arrays

Hey everyone,

I was wondering if anyone could help me figure out Postgres arrays with JDBC.

I have a connection to the database and I can put Data into the text array, but I can't seem to get it back out.

I'm also not sure I am even storing it properly. It is an array of text or text[] type. To store it I build a string in the following format:


That seems to be the way the postgres documentation indicates to store it. Is this the correct way to store a text[] type?

Also, how do I read it out. I see ResultSet has a getArray method, and I tried the following:

List list= Arrays.asList(rs.getArray("COLUMNNAME").getArray());

Then if I do list.get(0) I get something like [Ljava.lang.String;@1e1962d which seems to be a reference to an array object of Type String.

Some help with this would be great!


I agree. Here's the link:
