What value could I insert into a bit type column?
提问by James Chen
I am trying to insert or edit the bit value to "0" or "1", but either returns me a blank.
我试图将位值插入或编辑为“0”或“1”,但要么返回空白。
Could someone tells me how to insert the value in it?
有人能告诉我如何在其中插入值吗?
Also, Is that possible to not use bit type but Boolean? I see there's a Boolean type in the list of types
另外,是否可以不使用位类型而是使用布尔类型?我看到类型列表中有一个布尔类型
Thanks
谢谢

Generally speaking, for boolean
or bit
data types, you would use 0
or 1
like so:
一般来说,对于boolean
orbit
数据类型,您会使用0
or1
喜欢这样:
UPDATE tbl SET bitCol = 1 WHERE bitCol = 0

回答by Alcides Queiroz Aguiar
If you're using SQL Server, you can set the value of bit fields with 0 and 1
如果您使用的是 SQL Server,则可以使用以下命令设置位字段的值 0 and 1
or
或者
'true' and 'false'
(yes, using strings)
'true' and 'false'
(是的,使用字符串)
...your_bit_field='false'... => equivalent to 0

Your issue is in PHPMyAdmin itself. Some versions do not display the value of bit columns, even though you did set it correctly.
您的问题在于 PHPMyAdmin 本身。某些版本不显示位列的值,即使您设置正确。
