Dynamic SQL enables us to generate and run SQL statements at run time. Dynamic SQL is needed when our SQL statements contains identifier that may change at different compile times. Simple Example of dynamic SQL: CREATE PROC sp_dynamicSQL @table_name NVARCHAR(20), @col_name NVARCHAR(2...

Unity networking provides the High Level API (HLA) to handle network communications abstracting from low level implementations.
