Tables are database objects that contain all the data in a database. In tables, data is logically organized in a row-and-column format similar to a spreadsheet. Each row represents a unique record, and each column represents a field in the record. For example, a table that contains employee data for a company might contain a row for each employee and columns representing employee information such as employee number, name, address, job title, and home telephone number.
Creating a basic table involves naming the table and defining its columns and each column's data type.
The SQL CREATE TABLE statement is used to create a new table.
Syntax
The basic syntax of the CREATE TABLE statement is as follows −
CREATE TABLE table_name(
column1 datatype,
column2 datatype,
column3 datatype,
.....
columnN datatype,
PRIMARY KEY( one or more columns )
);
