Though we are calling it as a bitwise operators, it always operate on one or more bytes i.e, it will consider the whole representation of the number when applying bitwise operators. By using some techniques, we can manipulate a single bit on the whole representation of the number as we wi...
But, for the example you used above, and most other examples using bitwise operators, indexes will not be used because there is no way to optimize the index seek since MySQL is not looking at the value of the index record, but instead a conversion of it. This is similar to why an ...

the latter of which preserves the most significant bit. Even though there’s difference between concepts, C does not provide separate operators. Additionally, the C standard does not specify the behavior, as it is defined by hardware implementation. As shown in the following example output, the ...
