1, here still use the last table, you can see the marked area, we will statistics on these areas, the most commonly used function SUM, at this time can be written as "=sum ((a1:e11=" D ") *1)", and then the array operation by Ctrl+shift+enter
2, if you are familiar with other functions, we can also use the Sumproduct function, as shown in the figure. Enter "=sumproduct ((a1

B) Use serde (serialize/deserialize) to format data during data serialization and deserialization.
This method is a little more complex, and the data control capability is also weaker. It uses regular expressions to match and process data, and th

implement secure signatures for the server to access the local client. If you want customers to trust your applet signature, you can spend hundreds of dollars to purchase a trusted signature certificate from the versign company under Ca.
This article mainly uses Tomcat as the middleware and describes the specific signature steps. $ java_home is the JDK installation directory, and $ atat_home is the tomcat installation directory.
To sign an applet, follow these steps:

Idea: first, we will find out the three tables, assuming a B c, and then combine a B with each other.
There is no relationship between them, so to connect them, we need to use rownum to use the full outer join and rownum to make table a B in the form of fields (rather than rows) in this way, data in different tables can be merged in the form of columns (the reason is that the union all minus interse
