On my system the test fails as well, seems to be the same issue as before. This solved it:

  q.prepare(QString("SELECT MAX(CAST(SUBSTR(%1, :prefixLength) AS INTEGER)) FROM %2;").arg(tableField, tableName));
  q.bindValue(":prefixLength", prefixLength + 1);

As some tables have special ids like "AStd::Expense" in kmmAccounts I added this to the test:

  testAddNewAccount();
  QCOMPARE(m->m_sql->highestIdNum(QLatin1String("kmmAccounts"), QLatin1String("id"), 1), 6ul);
  
And: Your solouting works well! Now we just have to check if other databases bevhave this way (```cast("some string" as integer)``` -> 0) as well.

Since GCI is over I can take over this task if you want.

I was able to successfully build and run KMyMoney with this function included in Debian Stable (using cmake 2.8.11.1 from backports). However, I was unsure how best to test the function itself, so please let me know if any issues arise.
