Extended length for varchar2 in Oracle 12c

Question

I thought I should give the new extended varchar2 limits in my Java application. Here's what I've done so far:

1. Changed MAX_STRING_SIZE to EXTENDED according to the recommended procedure.
2. Extended the column in question to 32767 characters.
3. Ran the program.

Java call ResultSet.updateString( str, idx ) runs fine, but when I come to ResultSet.updateRow(), I end up in a Java exception referring to an Oracle error:

java.sql.SQLException: ORA-01461: can bind a LONG value only for insert into a LONG column

Complete error stack (or at least the part that doesn't refer to my code) follows:

java.sql.SQLException: ORA-01461: can bind a LONG value only for insert into a LONG column

at oracle.jdbc.driver.UpdatableResultSet.executeUpdateRow(UpdatableResultSet.java:3317)
at oracle.jdbc.driver.UpdatableResultSet.updateRow(UpdatableResultSet.java:2281)

As far as I can reckon, this should be it. But either I have forgotten something fundamental, or this must be a bug (perhaps in the jdbc library).

Answer 1

You must use the JDBC driver from 12c.
