Thread: ResultSet is FORWARD_ONLY.
Hi everyone,
Recently we have upgraded postgres driver jdbc4 for 8.3. After that while executing rst.first(), it raise the exception.
The statment was created correctly as
dbconnection..createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
org.postgresql.util.PSQLException: Operation requires a scrollable ResultSet, but this ResultSet is FORWARD_ONLY.
at org.postgresql.jdbc2.AbstractJdbc2ResultSet.checkScrollable(AbstractJdbc2ResultSet.java:207)
at org.postgresql.jdbc2.AbstractJdbc2ResultSet.first(AbstractJdbc2ResultSet.java:292)
at org.apache.tomcat.dbcp.dbcp.DelegatingResultSet.first(DelegatingResultSet.java:326)
This statment worked in postgres 8.1 jdbc 3 driver but now its not.. Pleas help is solving this...

Its ok not to use first, right: q.open(); while (! q.eof()) { do something; q.next(); } (IANAJP) -Andy
