MySQL C++ connector MySQL_Prepared_Statement::getUpdateCount error - c++

Question

I'm using MySQL C++ connector version 1.1.0.
This is how my code looks like:
PreparedStatement *pStatement;
connection->setAutoCommit(false);
pStatement = connection->prepareStatement("UPDATE records "
"SET is_processed = ? "
"WHERE id = ?");
//LOOP BEGIN
pStatement->setInt(1, is_processed);
pStatement->setString(2, record_id);
pStatement->execute();
//LOOP END
int updated_records;
try
{
updated_records = pStatement->getUpdateCount();
}
catch(SQLException&e)
{
cout << "ERROR: " << e.what();
cout << " (MySQL error code: " << e.getErrorCode();
cout << ", SQLState: " << e.getSQLState() << ")" << endl;
}
connection->commit();
connection->setAutoCommit(true);
The exception is thrown with following output:
ERROR: MySQL_Prepared_Statement::getUpdateCount (MySQL error code: 0, SQLState: )
So it says totally nothing. What's wrong with getUpdateCount() function? Is there some way I can get more detailed error reporting level?
EDIT
Is there any other way to get updated rows count using mysql c++ connector?

Answer 1

I ran into this problem as well. I ended up taking a look at the source code. It appears that the source explicitly will throw an exception.
uint64_t
MySQL_Prepared_Statement::getUpdateCount()
{
checkClosed();
throw MethodNotImplementedException("MySQL_Prepared_Statement::getUpdateCount");
return 0; // fool compilers
}

Answer 2

I've finally found working solution:
int updated_records = 0;
//LOOP BEGIN
pStatement->setInt(1, is_processed);
pStatement->setString(2, record_id);
updated_records += pStatement->executeUpdate();
//LOOP END
cout << updated_records;
executeUpdate() return number of affected rows and it works without any error, so that's enough for me.

Answer 3

To clarify for others, because I was confused; do it like this:
pstmt = con->prepareStatement ("UPDATE localdata SET Val = ? WHERE ID = ?");
pstmt->setDouble (1, 7.77); // first "?"
pstmt->setInt (2, 0); // second "?"
pstmt->executeUpdate ();
The trick is setting the values according to their table type and order in the statement.
