Find Rows that have a different value

[lmoran89]

This sounds like it should be simple, but I am struggling. Thank you in advance

I have 2 columns of data similar to the below (but 44,000 rows). First column is an account number, second is an identifier. I need to identify the where an account number has both a 2 and 1.

212210	2
212210	2
212210	2
212210	2
212210	1
212210	1
212210	1
212210	1

Welcome to the board.

Yeah, this is an ugly formula, for sure. Interesting problem, though. Assuming your Account values start at A1, then:
=IFERROR( IF( AND( FIND( "1", A1), FIND( "2", A1)), "both", "?"), IFERROR( IF( FIND( "1", A1), "1", "??"), IFERROR( IF( FIND( "2", A1), "2", "???"), "neither")))

Welcome to the Board!

All things being equal, I think this is something that is probably easier accomplished in Microsoft Access, through a "Grouped" and a "Totals" Query. Access may handle that amount of data a little more efficiently too.
However, I realize that you may not have access to Access. If you do, though, let me know, and I can probably help you get what you need.

Joe4 - Agreed this is something that should be in Access. I had already loaded it, but your help is appreciated

Let's say the table named is "Table1" and the field names are "AccountNumber" and "Identifier", and the possible value for Identifier are the numeric values 1 and 2.
Then, go to Query Design, change to SQL View, and paste this query code in:

SELECT AccountNumber
FROM Table1
GROUP BY AccountNumber
HAVING (Sum(IIf([Identifier]=1,1,0))>0) AND (Sum(IIf([Identifier]=2,1,0))>0);

This should return all AccountNumbers who have both 1 and 2.

Thank you. I'm getting the "Enter Parameter Value" on the Identifier field though. The field was initially text, but changed the data type to number, but still getting that message

Whenever you see that, and you didn't set a parameter, it typically means you have a typo in the field name (in this case, the field name you are using in the query here does not exactly match the field name in the table).

Got it!

Thank you so much for your help

You are welcome.
