I have a string:
@string='TEST RESULTS\TEST 1\RESULT 1
The string/text remains the same except for the numbers
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)"
Looks like you already have a solution that met your needs but I have a little trick that I use to extract numbers from strings that I thought might benefit someone. It takes advantage of the FOR XML statement and avoids explicit loops. It makes a good inline table function or simple scalar. Do with it what you will :)
DECLARE @String varchar(255) = 'This1 Is2 my3 Test4 For Number5 Extr@ct10n';
SELECT
CAST((
SELECT CASE --// skips alpha. make sure comparison is done on upper case
WHEN ( ASCII(UPPER(SUBSTRING(@String, Number, 1))) BETWEEN 48 AND 57 )
THEN SUBSTRING(@String, Number, 1)
ELSE ''END
FROM
(
SELECT TOP 255 --// east way to get a list of numbers
--// change value as needed.
ROW_NUMBER() OVER ( ORDER BY ( SELECT 1 ) ) AS Number
FROM master.sys.all_columns a
CROSS JOIN master.sys.all_columns b
) AS n
WHERE Number <= LEN(@String)
--// use xml path to pivot the results to a row
FOR XML PATH('') ) AS varchar(255)) AS Result
Result ==> 1234510
You can script an sql function which can used through your search queries. Here is the sample code.
CREATE FUNCTION udf_extractInteger(@string VARCHAR(2000))
RETURNS VARCHAR(2000)
AS
BEGIN
DECLARE @count int
DECLARE @intNumbers VARCHAR(1000)
SET @count = 0
SET @intNumbers = ''
WHILE @count <= LEN(@string)
BEGIN
IF SUBSTRING(@string, @count, 1)>='0' and SUBSTRING (@string, @count, 1) <='9'
BEGIN
SET @intNumbers = @intNumbers + SUBSTRING (@string, @count, 1)
END
SET @count = @count + 1
END
RETURN @intNumbers
END
GO
QUERY :
SELECT dbo.udf_extractInteger('hello 123 world456') As output
OUTPUT: 123456

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.
This method uses SUBSTRING, PARSENAME, and PATINDEX:
SELECT
SUBSTRING(PARSENAME(c,2), PATINDEX('%[0-9]%',PARSENAME(c,2)), LEN(c)) Test,
SUBSTRING(PARSENAME(c,1), PATINDEX('%[0-9]%',PARSENAME(c,1)), LEN(c)) Result
FROM ( SELECT REPLACE(@val, '\', '.') c) t
Use PARSENAME to split the string. The text of the string won't matter -- it will just need to contain the 2 back slashes to parse to 3 elements. Use PATINDEX with a regular expression to replace non-numeric values from the result. This would need adjusting if the text in front of the number ever contained numbers.
If needed, CAST/CONVERT the results to int or the appropriate data type.
Here is some sample Fiddle.
Good luck.
