Expert Solution & Answer

Explanation of Solution

Table Creation:

Creating table comes under Data Definition Language (DDL).

The “CREATE TABLE” command is used to create a table by specifying the table name and then by listing the column in a single set of parentheses in the table.
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,

);

Creating table “EMP”:

CREATE TABLE EMP (

EMP_NUM CHAR(3)

EMP_LNAME VARCHAR(15)

EMP_FNAME VARCHAR(15)));

Explanation:

The above query is used to create a table structure named “EMP” . The attribute “EMP_NUM” is declared as “CHAR” and the attributes “EMP_LNAME” and “EMP_FNAME” is declared as “VARCHAR”.
