BINARY_INTENER用来描述不存储在数据库中,但是需要用来计算的带符号的 整数值。它以2的补码二进制形式表述。循环计数器经常使用这种类型。 PLS_INTEGER和BINARY_INTENER唯一区别是在计算当中发生溢出时, BINARY_INTENER型的变量会被自动指派给一个NUMBER型而不会出错, ...
In addition to these data types, there are other PL/SQL-specific data types such as BOOLEAN, BINARY_INTEGER, PLS_INTEGER, %TYPE, REF CURSOR, SYS_REFCURSOR (Oracle9 i specific), and user-defined subtypes. Table 3鈥 1 summarizes these data types....
