WebFeb 25, 2015 · The boolean data type has only two possible values: true and false. Use this data type for simple flags that track true/false conditions. This data type represents one bit of information, but its "size" isn't something that's precisely defined. Share answered Dec 20, 2008 at 18:14 William Brendel 31.6k 14 71 77 Add a comment 21 votes

WebJan 6, 2024 · One boolean isn't a lot, but a lot of them add up. Besides, it's a simple optimization that would have a significant impact. I hadn't seen any ways to read a single bit as a boolean or write a boolean as a bit to some value (stored as byte, short, int or long). Not in Java at least. Using BitSet is an option, but in a data class I should ...

The BIT data type, which can only store integers 0 and 1 apart from NULL, is commonly used as a workaround to store Boolean values, but workarounds need to be used such as UPDATE t SET flag = IIF (col IS NOT NULL, 1, 0) WHERE flag = 0 to convert between the integer and boolean expression.
