In php programming, the difference between using commas for echo and using dots is that using commas for echo The echo string is better than the. Connection. The reason is not mentioned. Let's take a look at the following two sentences: What is the result? 1+5=6？1+5=6？——————6？2？——————6.6？6.6？—————— I can only say echo '5 + 1 = '. 1 + 5; the result is 10, so the

[Valid Java] 6. Using Compound takes precedence over using inheritance, while using tivejava This is what any book will say, because we often don't need to inherit, but just want to extend the class, and we want to extend the attributes or classes corresponding to the methods, at this time, if the relationship between the two is a, this relationship does exist, y

We introduced the use of natural join in Oralce, which is a natural connection. The Using keyword in a join connection in Oracle is relative to the natural join. As we mentioned earlier, if you are using Natraul join, and if more than one field in two tables has the same name and data type, then the fields will be connected by Oracle. But there are times when we don't need to connect like this. We just need
