Question

I have a string:

@string='TEST RESULTS\TEST 1\RESULT 1

The string/text remains the same except for the numbers

1. need the 1 from TEST
2. need 1 from RESULT

to be used in a query like:

SET @sql =  "SELECT *
            FROM   TABLE
            WHERE  test = (expression FOR CASE 1 resulting IN INT 1)
                   AND result = (expression FOR CASE 2 resulting IN INT 1)"

Answer 1

Since you have stable text and only 2 elements, you can make good use of replace and parsename:

declare @string varchar(100) = 'TEST RESULTS\TEST 1\RESULT 2'

select cast(parsename(replace(replace(@string, 'TEST RESULTS\TEST ', ''), '\RESULT ', '.'), 2) as int) as Test
    , cast(parsename(replace(replace(@string, 'TEST RESULTS\TEST ', ''), '\RESULT ', '.'), 1) as int) as Result

/*
       Test      Result
----------- -----------
          1           2
*/

The replace portion does assume the same text and spacing always, and sets up for parsename with the period.
