The following example uses xp_sscanf to extract two values from a source string based on their positions in the format of the source string.

DECLARE @filename varchar (20), @message varchar (20);  
EXEC xp_sscanf 'sync -b -fproducts10.tmp -rrandom', 'sync -b -f%s -r%s',   
  @filename OUTPUT, @message OUTPUT;  
SELECT @filename, @message;  

Here is the result set.
