believe that the 99 SQL, Oracle Basic written test is just like playing (the most complete, the most classic entry-level Oracle query statement)1. Select * from EMP;2. Select Empno, ename, job from EMP;3. Select empno number, ename name, job work from EMP;4. Select Job from EMP;5. Select distinct job from EMP;6. Select distinct empno, job from EMP;Description: Because the employee number is not duplicated, it proves that all columns are not duplicated at this time, so duplicate columns cannot be

In the previous query, the result is all records in the table. If you want to only display records that meet certain conditions, you must use conditional query or a restricted query. Basic Syntax of conditional query: SELECT * | (specific column names, such as ename and empno) FROM table (table name) WHERE conditions Note: The where clause must be followed by the from clause. For example, query all information of employees whose salaries are greater than 2000 in the emp table. SQL> select

Information about employees with an annual salary of between 15000 and 20000 is displayed as MANAGER and SALESMAN: name, position, and annual salary. 8.

It seems that I have not reached this point yet.To put it bluntly, I recently wrote an online editor, which is similar to ewebeditor.

steps step by step. The third layer, shallow, is a little more complex, but this is the structure we often use to write programs. The following example shows how to automatically generate a makefile for the source file of the shallow hierarchy.The example source program structure is as follows:HelloIs our working directory. The Hello directory contains the main. C source file and five directories, including comm, tools, DB, network, and interface.
