Query to get large numbers or specific string from a string in SQL Server

Question

I have data like this:

DECLARE @t TABLE(
  MyString NVARCHAR(1000)
);

INSERT INTO @t VALUES 
 ('str1 0319100004919000913 str2 str3 str4 str5 # 42')
,('str1 #127/322410. str2 str3 25.05.2021 str4 12.31.2021 str4.4 str4.1 str6.93; str7: 213583300014958330100100010000000000.')
,('str1 str2 # 7  (str3. #0119200000120014883)')
,('str1 # 156 str2 05.31.2012; 0134200000120005404|NULL')
,('str1 str2 str3 #0321200014120000733 str4')
,('str1 str2 str3 07.07.2021 (RD-GK-320-21-LS-07-12-2021-DTR232) str4.4 str4.1 str6.93') --specific string begins with RD-...
,('str1 str2 str3 30.06.2021 (RD-GK-319-21-LS-12-31-2021-DTR67)str4.4str4.1str6.er67')
,('str1 # IMZ-2021-010906. str2 str3 30.08.2021 str 31.12.2021 str5. str4'); --specific string begins with IMZ-...

The output I expect is

large number:

 1. 0319100004919000913
 2. 213583300014958330100100010000000000
 3. 0119200000120014883
 4. 0134200000120005404
 5. 0321200014120000733

specific string:

 1. RD-GK-320-21-LS-07-12-2021-DTR232
 2. RD-GK-319-21-LS-12-31-2021-DTR67
 3. IMZ-2021-010906

And I want to implement it in SQL Server (Version: 2017 and above)

Answer 1

Please try the following solution.

SQL

-- DDL and sample data population, start
DECLARE @tbl TABLE(MyString NVARCHAR(1000));
INSERT INTO @tbl VALUES 
 ('str1 0319100004919000913 str2 str3 str4 str5 # 42')
,('str1 #127/322410. str2 str3 25.05.2021 str4 12.31.2021 str4.4 str4.1 str6.93; str7: 213583300014958330100100010000000000.')
,('str1 str2 # 7  (str3. #0119200000120014883)')
,('str1 # 156 str2 05.31.2012; 0134200000120005404|NULL')
,('str1 str2 str3 #0321200014120000733 str4')
,('str1 str2 str3 07.07.2021 (RD-GK-320-21-LS-07-12-2021-DTR232) str4.4 str4.1 str6.93') --specific string begins with RD-...
,('str1 str2 str3 30.06.2021 (RD-GK-319-21-LS-12-31-2021-DTR67)str4.4str4.1str6.er67')
,('str1 # IMZ-2021-010906. str2 str3 30.08.2021 str 31.12.2021 str5. str4'); --specific string begins with IMZ-...
-- DDL and sample data population, end

DECLARE @filter VARCHAR(10) = '#|.()';

SELECT value 
FROM @tbl
    CROSS APPLY STRING_SPLIT(TRANSLATE(MyString, @filter, SPACE(LEN(@filter))), SPACE(1))
WHERE TRY_CAST(value AS FLOAT) IS NOT NULL
    AND LEN(value) > 9;

SELECT value 
FROM @tbl
    CROSS APPLY STRING_SPLIT(TRANSLATE(MyString, @filter, SPACE(LEN(@filter))), SPACE(1))
WHERE LEFT(value, 3) IN ('RD-', 'IMZ');

Output #1

+--------------------------------------+
|                value                 |

|                  0321200014120000733 |
+--------------------------------------+

Output #2
