Error converting data type varchar to bigint

Hello everyone,
My objective is to bring back 1 record for an account that has moved/transferred to a new location. For the specific account I'm looking at, I continue to bring back two records, because there are two order numbers that are unique but were created and closed on the same dates. So the sub-queries that I'm using to bring back the max value doesn't work in this scenario. I've now tried to had min and max functions to the To order number, and the From order number which is now bringing me back the error message within the subject line, The code has been pasted below:

IF OBJECT_ID('TEMPDB..#tmp1o') IS NOT NULL DROP TABLE #tmp1o IF OBJECT_ID('TEMPDB..#tmp2o') IS NOT NULL DROP TABLE #tmp2o IF OBJECT_ID('TEMPDB..#tmp3o') IS NOT NULL DROP TABLE #tmp3o

Any and all help is greatly appreciated. Thank you.

Can you just use

SELECT TOP 1 ...
FROM #tmp2o
ORDER BY tie-break-sort-order

i.e. instead of using MAX etc. - so you only get just the one record?

You have database and application problems, requiring a re-write.

Tell your boss the code is terrible and maintenance might be more expensive than rewriting it. That code is guaranteed to be buggy.

My recommendation:
Use this to create an n-tier separation. Leave the database alone, create new stored procedures and perform this logic in the application (c#): http://systemdotpersistence.blogspot.com
