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。
DB2 UDB does not have native support for bit or Boolean data types, neither for bitwise operation nor for Boolean algebra operations.
DB2 UDB 沒有為位數(shù)據(jù)類型或布爾數(shù)據(jù)類型提供本機(jī)支持，它既不支持逐位操作，也不支持布爾代數(shù)操作。
