Aliasing

Aliasing refers to the use of alternate names for database entities, expressions, or composite expressions where the database engine cannot infer a name or disambiguate two or more expressions as they have identical names.

To work effectively with Microsoft SQL Server, dbExpression exposes the ability to alias any one of the following:

• Column
• Table
• Subquery (an alias is required when using these)
• Any composition of functions and expressions where a name cannot be inferred by the database engine
