. There are several solutions for the above problem:Use global buffersCreates a buffer and then releases it at the end of the operationUse a Collection object to manage these sockets and other data, such as buffer arraysThe first method is obviously not very good, because we all know that using global variables is bad. Also, what if two instances use the same buffer?Here's the second way implementation:

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
