A table is a two-dimensional logical structure and the fundamental means of storing data in relational database management systems. Its ‘row and column’ format is very much like the organization of the spreadsheet.
Each new record introduced to a table is a row (also called a record or tuple), while rows are grouped into a finite set of columns (also called fields or attributes). Each column has a name and data type, and it serves as a reference for displaying result sets when querying data from relational database systems.
In this article, we explore the current options letting us add new columns to an existing table in SQL Server database. The use case may arise on many occasions. Particularly, it happens when there are updates for an application, and they demand adding new columns.
