How to order rows in a temp table?
I usually use temp tables in this way along with a column with a Row number using the ROW_NUMBER () function. It automatically orders the selected rows to the temp table. Or more simply, you can use the ORDER BY clause.
Why is SQL Server order by not working?
I have a query, and when I execute it in SQL Server 2012, the ORDER BY clause is not working. Please help me in this. Regards. SQL tables represent unordered sets. Is there something unclear about this? When you SELECT from a table, then the results are unordered. The one exception is when you use an ORDER BY in the outer query.
Why does neither query return the rows in the same order?
Both query does not return the rows in the same order. Any ordering behavior you might see without an explicit ORDER BY in the outermost query is by happenstance. The actual behavior depends on the query plan particulars that may change without warning between versions and service packs and break your code.
Why does the ORDER BY clause not work in table-valued functions?
I created a table-valued function like this: select * from uf_getdata (0) order by field3 desc, field2. This is a non sense, because the order by clause is exactly the same. It looks like if the results in inserted into the @temp table with a phantom index, before being returned, and the order by is not well respected.
Which is the best Order table to use?
I highly suggest you normalize this properly and use two tables: an Orders table which keeps a record for every order and an OrderItem table, which keeps the order key (referencing back to the Orders table), the item number and quantity as well as subtotal/total price.
What are the different types of temporary tables?

Temporary tables come in different flavours including, amongst others, local temporary tables (starting with #), global temporary tables (starting with ##), persistent temporary tables (prefixed by TempDB..), and table variables.
