Need to extract only numbers from the three strings. Below is the code I've tryed but it is extracting alpha characters to the letters 'ID'. SQL Server 2012

ABC -- Item Order for Custom ID 1234567; Doe, John

Item Order for Custom ID 7654321; Doe, Jane

Item Order for Custom ID 123456; Doe, Jack

SELECT substring(Field, 1, PATINDEX('%[0-9]%', Field) -1) AS CustomID
WHERE PATINDEX('%[0-9]%', Field) > 0

WHERE PATINDEX('%[0-9]%', A.PLNotes) > 0

Is Field and A.PLNotes related? Can you show some examples of the two columns Field and A.PLNotes?

If you are trying to extract the numeric portion from the example strings you have shown, something like shown below should work. But, it will work only if there is only one instance of consecutive numeric characters

DECLARE @s VARCHAR(256) = 'Item Order for Custom ID 123456; Doe, Jack';
SELECT LEFT(STUFF(@s,1,PATINDEX('%[0-9]%',@s)-1,''),PATINDEX('%[^0-9]%',STUFF(@s,1,PATINDEX('%[0-9]%',@s)-1,''))-1)

Sorry James and thanks for the reply. I didn't change 'A.PLNotes' to 'field' when I was modifying my example. I've updated my original post. What I'm trying to accomplish is; to extract only the numeric values from the strings below, it will not be a specific persons name.

You should be able to use the query I posted regardless of the characters/person's name that precede and succeed the numeric portion.

All you need to do is just modify your code as James showed you

SELECT LEFT(STUFF(Field,1,PATINDEX('%[0-9]%',Field)-1,''),PATINDEX('%[^0-9]%',STUFF(Field,1,PATINDEX('%[0-9]%',Field)-1,''))-1) AS CustomID from your_table
WHERE PATINDEX('%[0-9]%', Field) > 0
