If the person who called 911 on me leaves the state before we go to court what happens?

If they need her testimony in order to convict her and she does not come back then they have no case.

Looks good. Lot of defenses.

I would need more the details, but absolutely you need a good defense attorney. These are significant charges and can have many long-term future effects.

It depends. Some prosecutors will still try to prosecute a case (especially domestic violence cases) even though the complainant is not cooperative or is missing. They do this by attempting to introduce the 911 calls (if an appropriate evidentiary foundation is made) as well as testimony from the responding police officer to testify as to their observations (i.e., bruises , bleeding, other injuries, evidence of a scuffle, etc.) and even their conversations with the complainant (again assuming an appropriate evidentiary foundation is made). The DWI issue is complicated because there are issues of probable cause for the arrest, proof of operating a vehicle, timing and consent to any blood extraction.

They don't need your daughter. You need to hire a DUI specialist, and do it soon because you have only 10 days to save your license.

With these charges, I sure hope you are using the services of an attorney. Having said that, she could be brought back to testify. Absent her testimony, it may or may not impact your case. I would have to review the case file to determine how her testimony, or lack thereof, might impact your case.

In SC, Simple Assault and DUI are both serious criminal charges. With the DUI especially, there are a lot of very technical legal issues and administrative issues to deal with in a case like this. There are several factors, including but not limited to your daughter's testimony, that could seriously effect the outcome of this case. You should consult in person with a local attorney as soon as possible.
