C# 클래스 Deveel.Data.Sql.Expressions.SqlExpression

Defines the base class for instances that represent SQL expression tree nodes.

The architecture of the SQL Expression domain is to keep the implementation internal to the project, that means it will be possible to construct expressions only through this class, calling factory methods (for example Binary).
