Create table with data types

SQL> create table MYTABLE(name VARCHAR2(50),id NUMBER,salary NUMBER(8,2));

Table created

Now let us INSERT few records into MYTABLE.

SQL> insert into MYTABLE values ('CCC',1,2548.21);
SQL> insert into MYTABLE values ('ADS',2,3548.21);
SQL> insert into MYTABLE values ('GDS',2,1548.21);

SQL> select * from MYTABLE ORDER BY SALARY;
NAME   ID  SALARY
GDS   2    1548.21
CCC   1    2548.21
