Hi, 

I have a query:

UPDATE dbseXyzOrders.tblOrder SET intPoUid = 98 WHERE intOrderUid =
100000798

intOrderUid is the primary key

There are 25 columns in the table and a further 8 of these have indexes
on them. The table is innodb

I have just tried to run the above query 3 times and i got the follwing
error

Invalid Query Lock wait timeout exceeded; try restarting transaction

AFAIK innodb locks on row level, so does that mean that something else
is locking that row and won't let me update. If so how can i find out
what? 

Here is a copy of what mytop says at the time the query is being run

Thanks for any help
