Hash value generated does not match

user1356432Apr 9 2018 — edited Apr 13 2018

Hi,

We are using DBMS_SQLHASH.GETHASH to get the hash value of a result set for one of our requirements. The hash value generated by using the mentioned function in SQL * PLUS is different from that is generated in SQL Developer. Any idea about this discrepancy.

Thanks.

Regards; Gopal

JRE may not be enabled in your browser. Check whether it is enabled or not?

You can verify that from 'Tools -> Internet Options -> Advanced -> Java (sun)'

I'm having trouble deciphering that message as well. ..Mostly because you did not copy/paste it.

The JVM being used by the browser is earlier than the version of javac you compiled the applet with.

So update the browser's JVM or use the -target switch of javac.

If you get a message you can't 'decipher', post it. Just saying you can't decipher it only wastes time.

I'm running Java SE 7, which should be the latest version of Java available. Does this mean I need to update my compiler?

Sorry that I keep asking these questions but I want to make sure my applets will run properly in the future.

No, it means that your browser isn't running Java 7, but has an older plugin.

Then maybe use the target flag when compiling so it's compatible with 1.5. Version 1.6 tops. Unless you really need to use all the new features.
