Remesh,

When you execute the preparedStatement, what value is returned? Also, have you double-checked your bound parameters? You've ensured that the values are the same as what you've submitted via the other tools?

Finally, what SQL types are : NODE_ID and MASTER_ID ?

Kevin

Yes, the Table and column names have been modified/masked. I should have mentioned that.

thx.

I have been watching this thread. However, in the trace below one thing keeps sticking out at me. That is the line that prints "12/5/03 9:35 AM: statement to execute : UPDATE <TABLE>". The part that is confusing is '<TABLE>' Did you omit this from the post for security reasons? If not, I would suspect that a table name should be there.

Just a shot in the dark.

No, they are not :-)

Not too long ago, I got tripped up by something like this. turned out I was issuing commit() on the wrong connection.

are your id fields really strings?

No, other updates work fine, just this one for some

reason is not

working.

I also tried doing this with: Aspire (http://www.onjava.com/pub/a/onjava/2002/10/30/aspire.html)

That gives me a message saying the rows were updated, but I go see in the tables and it is not the case.

12/5/03 9:35 AM: statement to execute : UPDATE <TABLE> SET NODE_ID = '550' WHERE MASTER_ID = '157' AND NODE_ID = '552' 12/5/03 9:35 AM: Executing : UPDATE <TABLE> SET NODE_ID = '550' WHERE MASTER_ID = '157' AND NODE_ID = '552' 12/5/03 9:35 AM: Number of rows updated : 2 12/5/03 9:35 AM: db: Transaction being commited for request :request.UPDATE_PARENT_ID 12/5/03 9:35 AM: cp: Returning connection for pool aDB 12/5/03 9:35 AM: cp: Requesting a connection from data source aDB 12/5/03 9:35 AM: db: commit recognized

But as mentioned earlier, the same thing works fine from: SQLyog.

So, little confused as to where the problem might be.

thx

do you have auto-commit turned off?

Hi,

I am using: Driver: mysql-connector-java-3.0.9-stable-bin.jar Database: mysql 4.0.14

I am issuing a update stmt like: UPDATE <TABLE> SET NODE_ID = ? WHERE MASTER_ID = ? AND NODE_ID = ?

Using a PreparedStatement to do so, but it is just

failing, no

errors.

On the other hand, if I use a tool like: SQLyog and issue the same statement, it works fine.

What could be happening here?

Appreciate your input.
