doesn't answer the fundamental object-oriented question-Why do we use object-oriented objects. How should we use the three mechanisms to achieve "good object-oriented". What kind of object-oriented principles should we follow? Any serious object-oriented programmer, such as a C # programmer, needs to systematically learn object-oriented knowledge and object-oriented knowledge from programming languages and not be competent for object-oriented design and development. from an example Example sce

for database objects, it can also be used for login names. For example, you granted the NT group "domain Users to log on to SQL Server. Joe just got fired, but he doesn't know yet. You cannot simply use the REVOKE statement to cancel Joe's login because he is not granted the logon permission individually, but with other members as "domain A member of the Users group is granted logon permissions together. You can then use the DENY statement specifically against Joe. So he can't log in to SQL Ser

usually used in conjunction with the GROUP BY clauseNote: When group by is used for grouping, there can be no having clause. But when the having appeared, there must be a group byWhat you need to know is that the where statement filters the records before the group by statement, and the having is filtered after the various records are screened. That is, the HAVING clause is filtered after extracting the data from the database, so when you write the SQL statement, try to filter the data using th

(a) Introduction　　Oracle provides the ability to store a PL/SQL program in a database and run it anywhere, so it's called a stored procedure or function. procedures and functions are collectively known as PL/SQL subroutines, which are named PL/SQL blocks that are stored in the database and exchanged with their callers through input, output parameters, or input/output parameters. the only difference between a procedure and a function is that the function always returns data to the caller, and the

to the way that a variable is defined, but the variable name becomes the array name. After the array name, we use the brackets "[]" to elicit a constant representing the number of data elements in the array.Its detailed syntax forms such as the following:Data type array name [number of constants] [number constants] ...;, the data type represents the type of this series of bulk data.Example. We want to define an array that can hold the wages of multiple employees, and each employee's

Polymorphism is one of the three features of a polygon object other than encapsulation and inheritance, and I personally think that although it can be polymorphic in PHP, polymorphism is not as prominent as C + + and Java's object-oriented language, because PHP itself is a weak type of language, There is no problem with the conversion of a parent object to a subclass object or a subclass object into a parent object, so polymorphic applications are not so obvious; so-called polymorphism refers to

index of the column in the real data table, because in my file, the names of each column are actually "salary 1" "salary 2" "salary 3 "... Such a Chinese name. So the error "Undefined offset: 0 in C: \ inetpub \ wwwroot \ test \ fileRead. php on line 54" is displayed. So how can I solve this problem: when I don't know the index key of a column in advance, how can I retrieve them by index number? In actual functions, I need to query the database based on the column name, and insert the value of

DescriptionOier Company is a large specialized software company, with tens of thousands of employees. As a teller, one of my tasks is to count the wages of each employee. It was supposed to be a good job, but the depressing part is that our bosses are fickle and often adjust their employees ' salaries. If he is in a good mood, he may add the same amount to each employee's salary. Conversely, if the mood is not good, it is possible to deduct their wages by a similar amount. I really don't know wh

deduct their wages by a similar amount. I really don't know what else he's going to do in addition to the salary adjustment. The frequent adjustment of wages is very annoying to employees, especially when the collective deduction of wages, once an employee found that his salary is lower than the contract stipulated wages, he would immediately angrily leave the company, and will never come back. The lower bound of wages for each employee is uniformly defined. Whenever a person leaves the company

the many possible subtasks to complete the task. For example, if you start a database application in a window, the operating system will call the database as a process. Assume that you want to generate a payroll report from the database and upload it to a file. This is a subtask. In the process of generating a payroll report, you can access the database query request, this is another subtask. In this way,
