How to create an Oracle database in MySQL database Scott's tables

Let's take a look at the data structures of several tables of Scott users in Oracle:

==============================================================

The following operations are performed in the Oracle database (if required)

==============================================================

To create a table:

CREATE TABLE Dept (deptno INT PRIMARY key,dname varchar, loc VARCHAR (13)); CREATE TABLE EMP (EMPNO int (4) PRIMARY KEY, ename varchar (ten), JOB VARCHAR (9), MGR INT (4), HireDate DATE, SAL DOUBLE , COMM DOUBLE, Deptno int,foreign KEY (deptno) REFERENCES Dept (DEPTNO)); CREATE TABLE salgrade (grade int PRIMARY key,losal int,hisal int);

Insert test data:

insert into dept values  (, ' ACCOUNTING ', ' new york ');insert into dept  values  ("DALLAS");insert into dept values  (' SALES ', ' CHICAGO '); INSERT  INTO dept VALUES  (+, ' OPERATIONS ', ' BOSTON '); Insert into emp values (7369, ' SMITH ', ' Clerk ', 7902,date (' 1980-12-17 '), 800,null,20); Insert into emp values (7499, ' ALLEN ', ' Salesman ', 7698,date (' 1981-2-20 '), 1600,300,30); Insert into emp values (7521, ' WARD ', ' SALESMAN ', 7698,date (' 1981-2-22 '), 1250,500,30) insert into emp values (7566, ' JONES ', ' MANAGER ', 7839,date (' 1981-4-2 '), 2975,null,20) insert into emp values (7654, ' MARTIN ', ' salesman ', 7698,date (' 1981-9-28 ') , 1250,1400,30); Insert into emp values (7698, ' BLAKE ', ' MANAGER ', 7839,date (' 1981-5-1 '), 2850,null,30 ); Insert into emp values (7782, ' CLARK ', ' MANAGER ', 7839,date (' 1981-6-9 '), 2450,null,10); INSERT  into emp vaLues (7788, ' SCOTT ', ' ANALYST ', 7566,date (' 1987-4-19 '), 3000,null,20); Insert into emp values (7839, ' KING ', ' president ', null,date (' 1981-11-17 '), 5000,null,10); Insert into emp values (7844, ' TURNER ', ' Salesman ', 7698,date (' 1981-9-8 '), 1500,0,30); Insert into emp values (7876, ' ADAMS ', ' CLERK ', 7788, DATE (' 1987-5-23 '), 1100,null,20), insert into emp values (7900, ' JAMES ', ' Clerk ', 7698,date (' 1981-12-3 '), 950,null,30), Insert into emp values (7902, ' FORD ', ' ANALYST ', 7566,date (' 1981-12-3 '), 3000,null,20); Insert into emp values (7934, ' MILLER ', ' Clerk ', 7782,date (' 1982-1-23 '), 1300,NULL,10) ; Insert into salgrade values (1,700,1200); Insert into salgrade values (2,1201,1400 ); Insert into salgrade values (3,1401,2000); Insert into salgrade values ( 4,2001,3000); insert into salgrade values (5,3001,9999);

Summary: When creating a table, change the number to Int,varchar2 instead of varchar,datetime to date, and insert the table with the date function.

==============================================================

The following actions are performed on the MySQL user

==============================================================

CREATE TABLE Dept (deptno INT PRIMARY key,dname varchar, loc VARCHAR (13));

CREATE TABLE EMP (EMPNO int (4) PRIMARY KEY, ename varchar (ten), JOB VARCHAR (9), MGR INT (4), HireDate DATE, SAL DOUBLE , COMM DOUBLE, Deptno int,foreign KEY (deptno) REFERENCES Dept (DEPTNO));

CREATE TABLE salgrade (grade int PRIMARY key,losal int,hisal int);

=========================== Inserting Data ===========================

INSERT into Salgrade values (1,700,1200), insert into Salgrade values (2,1201,1400), insert into salgrade values ( 3,1401,2000) insert into Salgrade values (4,2001,3000), insert into Salgrade values (5,3001,9999);
