The three are actually talking about one thing. Of course, the focus here is not here. 1. The address of the shared body variable is the same as that of other members. 2. You Cannot initialize or assign values to shared object variables, or reference a shared object variable name to obtain the value of a member. (Excluding non-mainstream values such as * (int *) ( UnionVar). 3. The shared body cannot be passed as a function parameter, nor can it be returned as a function. (Do not exclude the sha

Many technicians can easily discuss the details of DB2 technology and confidently talk about query parallelism, data compression, WebSphere MQ integration, large object management, JDBC and ado.net drivers, data sharing on mainframe Parallel Sysplex, DB2 for Lin UX, Unix, and Windows (LUW) multidimensional clusters, and so on. But what happens if the person who talks is a member of the management? The main
