Query to solve if...
I've been doing a new database from a huge and messy 1-2-3 with multiple entries with some smalla differencies. While cleaning the table, I might have left some of the Computers with a user ID that doesn't exist in User table anymore, because I 'cleant' it. I mean there where same User name with many ID-numbers, and I changed in the computer table them to be the same and deleted the 'overcomes' from the User table. Just need to check that there aren't any computers without an existing user. Sorry my messy explanation.... -elli- "Ken Snell (MVP)" kirjoitti ... How do you want to use this value? Where are you wanting to look it up? That will help us help you to use the appropriate approach. "elli" wrote in message ... I have two tables.

Query to solve if...
Hi there! Thank You for your answer... I know Access can do almost anything
one can desire, but I have a problem not knowing it's potentials and functions. I know the query wizard, and done queries with it, but to accomplish this problem I am lost. But thank You for your help. -elli- "Ken Snell (MVP)" kirjoitti . .. OK .... in ACCESS, there is a query wizard that will create a query for you to find "unmatched" records. That is the easiest way to do what you seek. Try it, and post back with additional questions. -- Ken Snell MS ACCESS MVP "elli" wrote in message ...

Thank You Ken very much for your help. The SQL did it, and I could fix two pieces of info) U made my day! Take care -e- "Ken Snell (MVP)" kirjoitti ... What is confusing you in the wizard? It should lead you through each step fairly easily. You tell it that you want the Computers table to be the results for the query, then you tell it you want the Users table as the one that contains the related records, then you select the fields in both tables that would be related/linked (UserID?), then you specify the fields from Computers table that you want the query to show you, and then you are done. Otherwise, assuming that the names I've listed above are correct, this is the SQL statement of the query to show all Computer records containing a UserID that does not exist in the Users table: SELECT Computers.* FROM Computers LEFT JOIN Users ON Computers.UserID = Users.UserID WHERE Users.UserID Is Null; -- Ken Snell MS ACCESS MVP "elli" wrote in message ...
