The earlier sections describe the operation of the database engine in normal affinity mode.
QDB features two other affinity modes:
- Strict-affinity mode
- If a conversion between storage classes is required, the database engine
returns an error and the current statement is rolled back.
- No-affinity mode
- No conversions between storage classes are performed. Comparisons between values of
different storage classes (except for INTEGER and REAL) are always false.
