The main one is that with most JDBC drivers, the SQLException that 
try...catch intercepts is merely the first SQLEXception in a chain of 
SQLExceptions. You miss a lot of information about what went wrong by not 
repeatedly calling the current SQLException's getNextException() method 
until all members of the chain have been retrieved and their contents 
displayed. Alternatively, call SQLException.iterator and use that to 
iterate through the SQLException chain.
  
If the SQL query was at all complex then the first exception in the chain 
may not be particularly helpful because what caused the query to fail is 
described further down the chain.
