Select statement field connection (oracle)

Select statement field connection (oracle), such as employee name, employee position, birth date, and so on in the employee basic information table. If the three fields in the current view are displayed in the same field, there is a delimiter in the middle. For example, I want to display the result as "Manager Victor was born in May 3, 1976 ". What should we do? In fact, this is relatively simple. We can use the connector to connect these fields in the Select query statement. If www.2cto.com can write a query statement like this: SELECT employee position | ''| employee name | 'from '| as employee birth information FROM employee basic information table; you can use this statement to meet the preceding requirements. That is to say, in normal queries, we can use the | connector to connect some related fields. This is useful in the report view. For example, when I used to design a library management system, there were publishing houses and serial numbers in the basic information of books. However, when printing a report, you need to combine these fields into one field for printing. Therefore, you need to use this connector to connect these fields. Additionally, you can add descriptive text in the middle of the field to facilitate reading. For example, I added a space between the employee's position and employee's name, and added several annotated texts between the employee's name and date of birth. These functions seem relatively small, but can greatly improve the readability of the content. This is what we need to pay attention to in the database design process. In short, the later connector can improve the readability and flexibility of our reports.
