SQL Server - ALTER TABLE

The ALTER TABLE statement in SQL Server is used to add a new column to an existing table. In this case, we want to add a column with the data type tinyint.

The syntax for adding a column to an existing table is as follows:

ALTER TABLE table_name
ADD column_name tinyint;

Where:

• table_name is the name of the table to which the column is to be added.
• column_name is the name of the new column to be created.
• tinyint is the data type for the new column, which in this case represents a small integer between 0 and 255.

Keep in mind that the actual values stored in the tinyint column should be within the range mentioned above.

Here's an example usage of the ALTER TABLE statement to add a tinyint column named status to a table named users:

ALTER TABLE users
ADD status tinyint;

This will add a new column named status with the data type tinyint to the users table.

By adding a tinyint column, you can store small integer values efficiently, consuming less storage space compared to an int or bigint data type.

Remember to adjust the statement according to your specific table and column names.
