Invalid DEFAULT values for CREATE TABLE now generates errors. (Bug #5902)

Browse Source 
CAST() now produces warnings when casting a wrong INTEGER or CHAR values. This also applies to implicite string to number casts. (Bug #5912)
ALTER TABLE now fails in STRICT mode if it generates warnings.
Inserting a zero date in a DATE, DATETIME or TIMESTAMP column during TRADITIONAL mode now produces an error. (Bug #5933)
