Boolean一词,是根据19世纪英国数学家George Boolean(1815–1864)的名字而得,George Boolean为现代布尔代数之父。布尔型常量仅有两个值:真和假,分别用标准常量名TRUE和FALSE表示。它们的序号分别为1和0。用于布尔量的运算有布尔运算符(或称逻辑运算符),它们是:and(与)、or(或)、not(非),xor...

直到1975年,微软的Altair BASIC,才将AND/OR/NOT运算符添加进来,并且被描述为LOGICAL AND BITWISE(逻辑和按位),并且对于IF的任何非零表达式执行THEN子句。与此同时,False被定义为0(0x0000),True被定义为-1(0xFFFF)。 三、为何要将True映射为-1,而不是非0?

Yes, it's correct. the data type of the Boolean data in SQL Server is bit data type, and it could store 1,0 and NULL. Also, the string values TRUE and FALSE could be converted to bit values, which is mentioned at/en-us/sql/t-sql/data-types/bit-transact-sql?view=sql-server-201...
