Exercise 1 - Storing Data in Tables

A table is a collection of rows that have associated columns. In other words, a table stores the data you provide in rows and columns. You create a table by providing a name for the table and defining its column names and column data type. Each column then holds the respective data to be stored. Each row in a table contains each of the column’s data.

  • Create tables and store data

Exercise 2 - Create Tables using Transact SQL and SQL Management Studio

Data in a database are stored in tables. Hence, you need to first define the respective tables to store your data. For example, consider you need to store the details of company products. For this, you need to define a table with columns corresponding to the information to be stored.

A table definition contains the table name, column names, and column data types. Therefore, before creating a table, you must decide on the table name, the field names or column names and their data types to be included in the table definition. A column name should be unique to a specific table. However, the same column name can be used in different tables within the same database. You can also specify whether a specific column can contain null values or not in the table definition. If you do not specify NULL or NOT NULL constraint, the SQL Server 2016 default is NULL.
