问题
I am needing to sort a field on everything after a space usig SQL. In the example below, I would like it to sort (ascending) beginning with the last name.
USA-J. Doe
USA-M. Mouse
USA-A. Mouse
USA-D. Duck
USA-P. Panther
USA-T. Bird
I need it to sort the entire string, but on the last name. If there are two last names that are identical, I would like for it to take the initial of the first name into account. The result would be:
USA-T. Bird
USA-J. Doe
USA-D. Duck
USA-A. Mouse
USA-M. Mouse
USA-P. Panther
I will need to use this code in both SQL Server and MS Access.
I hope that someone can fully answer this question. For whatever reason, someone has scored me a -1 on this question. I cannot figure out why. I have been as specific as I know to be and I wasn't able to find an answer to the final piece--sorting by first letter if the last name is the same.
Thank you guys for responding. The information helped. I had to add brackets around "name" because the name of the field was similar to the name of the actual table.

This depends on the database. The following is how you might do this in SQL Server:
order by substring(name, charindex(' ', name) + 1, len(name)))
Similar logic works in other databases but the functions are different.
For instance, in Oracle:
order by substr(name, instr(name, ' ') + 1)
And, in MySQL, you could use similar logic, but this is simpler:
order by substring_index(name, ' ', -1)
And in MS Access:
order by mid(name, instr(name, ' ') + 1)

For sorting by lasname, firstname you need to use like this in SQL server:
order by substring(name, charindex(' ', name) + 1, len(name))), substring(name, charindex('-', name) + 1, 1))
In Access
order by mid(name, instr(name, ' ') + 1), order by mid(name, instr(name, '-') + 1, 1)
