Answer 1

A split function can be found here

declare @str varchar(100) 
set @str = "val1_val2,val3_val4"


declare @str varchar(100) = 'val1_val2,val3_val4'

select substring(f.value, 0, charindex('_', f.value)) as val1
      ,substring(f.value, charindex('_', f.value) + 1, LEN(f.value) ) as val2
from dbo.fnSplitString(@str, ',') f

There is a nice answer here:

http://www.codeproject.com/Articles/7938/SQL-User-Defined-Function-to-Parse-a-Delimited-Str

Using this function you could just use:

SELECT fn_ParseText2Table 'val1_val2,val3_val4', '_'
