So we talked about Mr. Bool briefly last week in this idea of true or false, but in C, you don't have a Boolean data type.
我們上周簡短地談?wù)撨^Bool先生的,真假的邏輯思想，但是在C語言里，沒有布爾數(shù)據(jù)類型。
and we have the following PL/SQL SQL statements that manipulate with columns flag1 and flag2 (both of BOOLEAN data type)
并且具有下列 PL/SQL SQL 語句，可以使用它們在列 flag1 和 flag2（均為 BOOLEAN 數(shù)據(jù)類型）上進行運算
