by SQL Server's grammatical structure combination. However, if you need to export from this syntax tree to other databases such as Sybase executable SQL statements, it is also in the TSQL class to add a new traversal algorithm, all the relevant code to recompile. By using the visitor pattern, the algorithm of combining the syntax tree nodes when traversing nodes is encapsulated in the method of the visitor, such as SQL Server's syntax is a Tsqlservervisitor class, and the syntax tree will call
