On Monday, the ISO C++ committee completed its final full-committee (plenary) meeting of 2020 and adopted the first changes to the C++23 working draft, including a few new features. First up was P0330 by JeanHeyd Meneide , which adds a literal suffix for (signed) size_t, so in C++23 we will be able to write literals like 100uz.

Of course, I’ll demonstrate this design aspect in this article. What’s different about the design of CTEs compared to derived tables is where in the code these three elements are located. However, there are very few cases in T-SQL where without a terminator the code is ambiguous. The elements are sort of intertwined.
