All,
Someone asked me to take a look at this and set up a nice little demo
program using SQLite. I couldn't believe it when I tried this.
void SQLiteModel::deleteRow(int rowNo)
{
qDebug() << "removeRow called for " << rowNo << "\n";
bool rslt = removeRow(rowNo);
qDebug() << "result of removeRow() " << rslt << "\n";
qDebug() << "Error: " << lastError().text() << "\n";
qDebug() << "query: " << query().lastQuery() << "\n";
submitAll();
}
removeRow called for 3
result of removeRow() false
Error: "near \"WHERE\": syntax error Unable to execute statement"
query: "select * from questions;"
Every I/O operation performed within the model fails with that exact
same error whether it is a nothing table like this:
query.exec("CREATE TABLE IF NOT EXISTS questions (Q_NO INTEGER PRIMARY
KEY, Q_TEXT TEXT);");
or a slightly less than nothing.
query.exec("CREATE TABLE IF NOT EXISTS questions (Q_NO INTEGER PRIMARY
KEY AUTOINCREMENT, Q_TEXT TEXT NOT NULL);"
It appears this has been broken for at least a year.

I have a full program to test with if someone wants it.
