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

now only if PKEY is present, this should also work when there's no PKEY

safe to cast it?

maybe use tables_byname?

Member KDbQuerySchema::validate (QString *errorMessage=nullptr, QString *errorDescription=nullptr)

add tests

Class KDbRecordData

consider forking QVariant to a non-shared Variant class, with type information stored elsewhere.

Variant should have toQVariant() method

look if we can have zero-copy strategy for SQLite and other backends

look if we can use memory allocator for strings, etc.
