In fact, the application where 1 = 1 is neither an advanced application nor an intelligent construction, it is just a method used to construct a dynamic SQL statement that can run correctly to meet the uncertainties in the Multi-condition query page.

In other words, one Chinese Character occupies 2 bytes of storage space.KB: In the general unit of measurement, K indicates 1000. For example: 1Km = 1000 meters, often written

in the C language. I found that some developers know very little about these things. In any case, the answer to this unsigned integer is "> 6 ". The reason is that when there are signed and unsigned types in the expression, all operands are automatically converted to the unsigned type. Therefore,-20 is a very large positive integer, so the result calculated by this expression is greater than 6. This is very important for embedded systems that should frequently use the unsigned data type. If you
