If the nonclustered index is over a heap, the data row locator is the heap RID. This is a size of 8 bytes. Num_Key_Cols=Num_Key_Cols+ 1 Num_Variable_Key_Cols=Num_Variable_Key_Cols+ 1 Max_Var_Key_Size=Max_Var_Key_Size+ 8 ...
This assistant can automatically convert Chinese variable names into English variable names that conform to camelCase, PascalCase, snake_case, kebab-case, and constant naming conventions based on specific naming rules.
