Обсуждение: Primary Key Error Updating Rows in ResultSet

Hi,

I'm getting the error 'java.sql.SQLException: No Primary Keys' when
trying to update a resultset based on a table with a primary key.

The exception appears to be occuring when I call the updateObject()
method.


I'm using pg74.215.jdbc3.jar & postgresql 7.4.6.

Any suggestions?

It is not enough to have a primary key on the table, you must also select
those columns in your ResultSet.  Further, the code to determine the table
in question isn't very good and is easily fooled.  What is your exact
SELECT statement and primary key definition?

If you have in fact included the trailing semi-colon on the SELECT
statement I believe the driver determines the table name is "targets;"
instead of "targets".  Either leave it off or put some whitespace between
it and the tablename.
