The ORACLE tutorial is Oracle PL/SQL getting started. I have already learned the basics of PL/SQL programming. This article will use a case study to deepen my understanding of these knowledge points. I. Case Study A database has two tables about employee information, salary, and department information of a company. They are emp and dept tables. The structure of the two tables is as follows: The requirement

I uninstalled PL/SQL Developer and compared it with Toad for Oracle. Previously, PL/SQL Developer was used to manage Oracle, which was inconvenient to use. It is very difficult to open, and there is always an extra box in the upper left corner of the interface. It cannot be set to hide it by default. The only thing that makes it worthwhile is to have a beautification tool, but later I found that Toad actu

To use the Pl/sql program to complete a more complete database task, you need to further learn some advanced design elements of the content. The Pl/sql program that was written earlier, common to the absence of names, can only be stored as files, and then executed through the execution of files, so called nameless blocks. This corresponds to the introduction of some concepts of advanced programming in

It allows SQL's data manipulation language and query statements to be included in the Block structure (block_structured) and the code process language, making PL/C a powerful transactional language. In Oracle database management, PL/SQL is a procedural language extension to Structured Query Language (SQL). The purpose of

The PL/SQL cursor allows the program to select multiple rows of data from the database, and then separately process each row of data, it provides Oracle with a method to indicate and control each stage of SQL processing. I think you have some knowledge about PL/SQL. Through this article, you will learn: Creation of cursor Processing the cursor Define and use cursor Properties 1. What is the cursor?Or

Many Oracle database developers prefer PL/SQL functions, storage, and so on to simplify the code. Recommended reading: Use PL/SQL to execute java storage to obtain the MAC address For example: Select empno, ENAME, DNAME, loc from emp, dept where emp. DEPTNO = DEPT. DEPTNO; Developers may think that such an SQL statement is too long (Here we assume that the SQL statement is too long). They like to use functi
