this field can be notNull or notEmpty - check whether the default is ok (or do this checking also in the Table Designer?)
support unique, validatationRule, unsigned flags...
check for foreignKey values...
For some cases, table schema can completely change, so it will be needed to refresh all objects depending on it. Implement this!
- Member KDbAlterTableHandler::InsertFieldAction::execute (KDbConnection *conn, KDbTableSchema *table) override
- Member KDbAlterTableHandler::InsertFieldAction::simplifyActions (ActionDictDict *fieldActions) override
- not checked
- Member KDbAlterTableHandler::InsertFieldAction::updateAlteringRequirements () override
sometimes add DataConversionRequired (e.g. when relationships require removing orphaned records) ?
- Member KDbAlterTableHandler::InsertFieldAction::updateTableSchema (KDbTableSchema *table, KDbField *field, QHash< QString, QString > *fieldHash) override

- Member KDbBinaryExpressionData::typeInternal (KDb::ExpressionCallStack *callStack) const override
add general support, e.g. for "NULL AND (1 == 1)"; for now we only support constants because there's no evaluation and operations with NULL depend on whether we have TRUE or FALSE See https://www.postgresql.org/docs/9.4/static/functions-logical.html https://dev.mysql.com/doc/refman/5.0/en/logical-operators.html
Any OR NULL may be also TRUE – but this needs support of fuzzy/multivalue types

look at the current format version (KDB_EXTENDED_TABLE_SCHEMA_VERSION)
- Member KDbConnection::prepareStatement (KDbPreparedStatement::Type type, KDbFieldList *fields, const QStringList &whereFieldNames=QStringList())
- move to ConnectionInterface just like we moved execute() and prepare() to KDbPreparedStatementInterface...
