The SQL clause ORDER BY CustomerLastName DESC sorts the results of a query based on the values in the CustomerLastName column. The DESC keyword specifies that the sorting should be done in descending order, meaning that names will be listed from Z to A. This clause is typically used to organize data for easier reading or to prioritize records based on the specified column.

What is it called when you want to see database records in a certain order?
When you want to see database records in a certain order, it is called "sorting" or "ordering."

Why you use order by and having clause in sql?
They do completely different things, so I'm not sure why you grouped them into one question.ORDER BY is pretty straightforward: it arranges the results to be in alphabetical or numerical order (or the reverse, if you use ORDER BY column_name DESC). Without it, you get the results in whatever order the database feels like giving them to you, which can and probably will change as new rows are added.The HAVING clause is a little trickier. It's used to restrict the selection based on grouped results (in other words, you can think of it as a variation on the WHERE clause). It can be used to e.g. find duplicates:SELECT Should_Be_Unique_IDFROM MyTableGROUP BY Should_Be_Unique_IDHAVING COUNT(*) > 1;
How do you set up ascending and descending order in a table and a query?
I'm actually not familiar with Access, but I'll try to help. Usually the primary key will physically order the rows in a database table. In SQL-query you can use "order by" clause. The default order is usually ascending. You can also add "asc" or "desc" after the column name. Please do notice, primary keys are not for ordering rows. You should really let the database decide how to save the rows. You should always order the rows in your query (if needed), not modify or trust the physical order! select col1 from foo order by col2 select col1 from foo order by col2 desc, col3 asc
