Question

I have a complex scenario for string matching and want input from you guys.
I have a table Named Customers. This table contains a field CustomerName varchar.
Data in the column is prefixed with Mr. Mrs. Ms.
Data could be

1. Mr. John Brady
2. Ms. Abraham Lenin
3. Mrs. John Brady
4. Mr. Michael King
5. Mrs. Neil Thomas
6. Mrs. Micheal King

Now I need to design a search query that returns me rows of only Couples and in a sequenced manner.

Like Select CustomerName from Customer where …??
Result needs to be like

1. Mr. John Brady
2. Mrs. John Brady
3. Mr. Michael King
4. Mrs. Micheal King

Any Idea ?

Thanks in advance for the consideration.

         count(*) over(partition by stuff(Name, 1, charindex(' ', Name), '')) as Cnt
  from @T
