1. Access modifiers of members in the class
The location modifier is the region that the member can access (use. In C #, the following modifiers are commonly used: pubic (public), private (private), internal (Inline), and protected (protected ). The Restricted Area of each modifier is illustrated.
Copy codeThe Code is as follows: class TestClass
{
Public int a = 0;
Private int B = 0;
Protected int c = 0;
Pulic static int d = 0;}
In the TestClass class, variable a is of the Public type and can b

You can use the GROUPING_ID function to filter records with the HAVING clause, removing records that do not contain subtotal or total. The GROUPING_ID () function can accept one or more columns and return the decimal value of the GROUPING bit vector. The calculation method of the GROUPING bit vector is to combine the results of calling the GROUPING function for each column in sequence. 1.

Let's take a look at what happens if you use normal group by without ROLLUP.
SQL> select pision_id, sum (salary)2 from employees23 group by pision_id4 order by pision_id;
Div sum (SALARY)--------------BUS 1, 1610000OPE 1320000SAL 1, 4936000SUP 1015000
The final statistics are missing.
2. Pass multiple columns to ROLLUP
SQL> select pision_id, job_id, sum (salary)2 from employees23 group by rollup (pision_id, job_id)4
order by division_id, job_id;
Div job sum (salary)-----------------Bus Mgr 530000Bus pre 800000Bus wor 280000Bus 1, 1610000OPE Eng 245000OPE Mgr 805000OPE wor 270000OPE 1320000Sal Mgr 4446000Sal wand 490000Sal 1, 4936000

As you can see, in addition to the last sum record, each division_id group also has a sum record.

bluntly, it is not human-friendly. At this time, we can use CASE to convert to some meaningful values.

Sometimes, you need to create a data structure when programming. There are data members in this data structure that have methods (or only data, only methods are possible), but these are common things, it does not need to interact or change during running, and the content is correlated. I want them to be a relatively whole block, so it naturally needs to be a structure or class, however, I don't want this block to be converted out of the instance, and I don't want it to be inherited.
