Previously I have asked to strip text from a field and convert it to an int, this works successfully. But now, I would like to do an INNER JOIN on this new value.
So I have this:
SELECT CONVERT(int, SUBSTRING(accountingTab.id, PATINDEX('%[0-9]%', accountingTab.id), 999)) AS 'memId', userDetails.title, userDetails.lname FROM accountingTab INNER JOIN (SELECT id, title, first, last FROM memDetTab) AS userDetails ON memID = userDetails.id
And then I get the Invalid Column Name memID error.
How can I fix this?
If you have to do this, you have design problems. If you’re able, I would suggest you need to refactor your table or relationships.
