Expert Solution & Answer

Explanation of Solution

Table Creation:

Creating table comes under Data Definition Language (DDL).

The “CREATE” command is employed for establishing databases on our platform by constructing tables in an already existing database.

The Syntax for creating table is as follows:

CREATE TABLE TABLE_NAME (

Column1 datatype,

Column2 datatype,

…

);

Example:

Creating table “EMP_1”:

CREATE TABLE EMP_1 ( EMP_NUM CHAR(3) , EMP_LNAME VARCHAR(15) , EMP_FNAME VARCHAR(15) , EMP_INITIAL CHAR(1), EMP_HIREDATE DATE, JOB_CODE CHAR(3));

Explanation:

The above query is used to create a table structure named “EMP_1” . The attribute “EMP_NUM”, “JOB_CODE”, “EMP_LNAME” and “EMP_FNAME” are declared.
