BETWEEN AND

Sintassi

expr BETWEEN min AND max

Spiegazione

Se expr è maggiore o uguale a min ed expr è minore o uguale a max, BETWEEN restituisce 1, altrimenti restituisce 0. Ciò equivale all'espressione (min <= expr AND expr <= max) se tutti gli argomenti sono dello stesso tipo. Altrimenti avviene una conversione tra tipi come spiegato alla pagina Type Conversion, ma applicata a tutti e tre gli argomenti.
