| assessment criterion | Flags the deficient case and passes the acceptable one. Deficient: `account_currency_code VARCHAR(50)`: `'EUR'`, `'eur'` and `'EUR '` all load. `account_identifier VARCHAR(10)` for a logical length of 20. `payment.account_id INTEGER` referencing `BIGINT`. A date as `VARCHAR`. A name column in a character set that cannot hold õ, ä, ö, ü, š, ž Acceptable: `CHAR(3)` with an uppercase-letters check; lengths at least the logical ones; foreign-key types identical to the referenced key; `DATE`; a Unicode character set (`PHY-008`, `PHY-023`) en |
