add the CLOSE_CURSORS_AT_COMMIT Option to the Statements capabilities e.g.
Statement st = db.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE.ResultSet.CLOSE_CURSORS_AT_COMMIT);
//then tell the connection handle to commit the DML to the DB

Subject: [GENERAL] need help of getting PK after insertRow in JDBC
Date: Fri, 26 Sep 2008 10:14:01 +0800
To: firstname.lastname@example.org; email@example.com
I am a software engineer from GE. I am using JDBC to operate PostgreSQL8.3 in Ubuntu8.04. The develop environment is Eclipse3.2 My problem is:
There is a PostgreSQL table XX containing 5 fields: AA, BB, CC, DD, EE, AA is primary key and auto-generated type, BB, CC, DD and EE is string type.
I want to get the value of AA immediately after insert a row into the table. the code is like this:
Statement st = db.creatStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
ResultSet rs=st.executeQuery("SELECT * FROM XX");
int index = rs.getInt("AA");
in the last sentence I always get 0 no matter how many records I insert. I tried other ways of moving the cursor including next(), last() and so on, and also cannot get the correct value. I tried the drivers both postgresql-8.3-603.jdbc3.jar and postgresql-8.3-603.jdbc4.jar.
But when I use pdadminIII to check the table XX, the AA field is already auto-generated with the correct value.
I found a way to solve this: close resultset and statement after moveToCurrentRow() and re-open them, and rs.last(), then run int index=rs.getInt("AA"), I can get the correct value. I think this method is sort of awkward, anyone knows a better way and the correct operations?
I am not sure it is proper to send this mail to this mail list. Sorry if bring you any inconvenience.
Thanks a lot!
