Question

I have the following java code:

if (ps.executeUpdate() != 1)
  {
    // Error - did not insert one row
    String err = "insert unable to insert LocalUsage data: " + usg.toString();
    Logger.log(err, _MODULE_CLASS, Logger.DEBUG);
    throw new DaoException(err);
  }

The problem if the query had a foreign key exception, then it will be thrown but it will never get to inside the if. what should I do so that it will get inside the if and output the log I have?

The problem is that this if condition is inside a try catch block, and it is going to the catch and never enters to the if condition.

Answer 1

executeUpdate() might throw an SQLException, as is described in its API documentation. You might want to catch that exception.

int count;
try {
    count = ps.executeUpdate();
} catch (SQLException e) {
    throw new DaoException("Exception while executing update: " + e.getMessage());
}

if (count != 1) {
    // ...
}
