SQL concatenation means combining two or more text values into a single string. Database systems provide different methods and functions for concatenation, such as CONCAT or the concatenation operator depending on the database system.
Business data is often stored across multiple columns. Concatenation allows analysts to create useful combined values such as full names, complete addresses, product descriptions, or display labels.
