Review comment:
+1 to catch everything here. Even we are able to wrap all exceptions into
`SqlExecutionException`, there still would be some unexpected errors, like NPE
or something like that. There is no real harm for catching everything here,
users still can see the error messages from console, knowing something went
wrong.
