(Error 3073) Microsoft Access up vote 17 down vote favorite access operation must use an updateable query linked table 4 On some Microsoft Access queries, I get the following message: Operation must use an updatable query. (Error 3073). I work around it by using temporary tables, but I'm wondering if there's a better way. All the tables involved have a primary key. Here's the code: UPDATE CLOG SET CLOG.NEXTDUE = ( SELECT H1.paidthru FROM CTRHIST as H1 WHERE H1.ACCT = clog.ACCT AND H1.SEQNO = ( SELECT MAX(SEQNO) FROM CTRHIST WHERE

You aren't using a JOIN, but the WHERE clause is exactly equivalent to a join, and thus, the Jet query optimizer treats it the same way it treats a join. I'm afraid you're out of luck without a temp table, though maybe somebody with greater Jet SQL knowledge than I can come up with a workaround. BTW, it might have been updatable in Jet 3.5 (Access 97), as a whole lot of queries were updatable then that became non-updatable when upgraded to Jet 4. -- share|improve this answer edited Oct 24 '12 at 13:53 Anirudh Ramanathan 32.3k1177123 answered Oct 4 '08 at 21:12 David-W-Fenton 19.3k22947 Thanks for the explanation. –Knox Oct 5 '08 at 17:02 1 So we have a pretty trivial update statement (UPDATE CLOG SET CLOG.NEXDUE = ...

This brief article explains the cause of the error, and the steps required to stop it recurring. When a Jet 4.0 database (the actual type of database represented by your "Access" mdb file) is deployed in a multi-user http://stackoverflow.com/questions/170578/operation-must-use-an-updatable-query-error-3073-microsoft-access environment, an .ldb file is created whenever the database is opened. The .ldb file contains details which include who has opened the file, and primarily serves to prevent opened records being written to by another user. In the context of an ASP.NET application, who the "user" is will depend on the platform: for XP Pro machines, the user is the ASPNET account. On Windows Server 2003, 2008 and Vista, it is the NETWORK SERVICE account. However, if you http://www.mikesdotnetting.com/article/74/solving-the-operation-must-use-an-updateable-query-error have ASP.NET Impersonation enabled, the default user account will be IUSR_machinename, or whichever account you have applied. With IIS 7.5, Application Pool Identities were introduced, which will result in your application running under an account named "IIS APPPOOL/name_of_application_pool", If you are unsure which account your ASP.NET application is running under, Environment.UserName will return it. To be able to create, write to and delete the required .ldb file, the relevant user needs MODIFY permissions on the folder that the .mdb file is in. To set this permission, right click on the App_Data folder (or whichever other folder you have put the mdb file in) and select Properties. Look for the Security tab. If you can't see it, you need to go to My Computer, then click Tools and choose Folder Options.... then click the View tab. Scroll to the bottom and uncheck "Use simple file sharing (recommended)". Back to the Security tab, you need to add the relevant account to the Group or User Names box. Click Add.... then click Advanced, then Find Now. The appropriate account should be listed. Double click it to add it to the Group or User Names box, then check the Modify option in the permissions. That's it. You are done. Note: this fix will also solve "The Microsoft Jet database engine cannot open the file '(unknown)'. It is already opened exclusively by another user, or you
