In terms of storage, the Bit data type is optimized by the SQL Server. If you have eight or fewer Bit columns in the table, SQL Server stores them as 1 byte. Similarly, for 9 to 16-bit columns, it consumes 2 bytes. Additionally, SQL Server converts String values TRUE and FALSE into...
bit数据类型:存储1位值,存储上有优化,如果一张表中少于8个的bit列,他们将被存储在一个字节中,通常用来存储boolean值;在SQL Server中bit值没有字符串形式,True和False只是可以转化为bit值,就像整数值1、0可以转化为bit值一样,底层bit值存储的不是True或False,也不是整数值1、0,而只是一位值而已;高级语言中Fal...
bit类型存储 0 和 1 ,只需要使用 1 bit 就能表示,但是,在存储到Disk时,SQL Server按照Byte来分配存储空间。如果表中只有1个 bit 列,那么该列将会占用1Byte的空间,一个Byte最多存储8个bit列。 The SQL Server Database Engine optimizes storage ofbit columns. If there are 8 or lessbit columns in a ...
