After being searching the net for the concrete fix for the issue and finishing unsuccessfully, I downloaded the following cumulative fix: SQLServer2008R2-KB2703280-x64 and installed it. The issue was resolved.I also tried using a Login with different databases with different collations on an sql server 2005 instance and it worked there without any issues.RegardsIgorMiWed, 26 Sep 2012 13:20:27 GMTIgorMiRE: collation issue raised by a system UNION queryhttp://www.sqlservercentral.com/Forums/Topic1364246-1550-1.aspxHi GSquared,Yes sure, if it was for a production I'd have gone with microsoft directly. This is, fortunately, not a problem on productions as their databases have same collation as the server instance. I do restores from more productions on a test server , and the backups are coming with different collations. Moreover the test server is a virtual machine. I cannot make a system restore. I'll probably try with latest cumulative hotfixes for sql server 2008r2.Additionally, can someone tell me if this is resolved with sql server 2012 ?ThanksIgorMiTue, 25 Sep 2012 14:49:44 GMTIgorMiRE: collation issue raised by a system UNION queryhttp://www.sqlservercentral.com/Forums/Topic1364246-1550-1.aspxI'd go straight to Microsoft on this one, if Bing/Google/whatever doesn't pull something useful up straight off the error message.Tue, 25 Sep 2012 14:13:52 GMTGSquaredcollation issue raised by a system UNION queryhttp://www.sqlservercentral.com/Forums/Topic1364246-1550-1.aspxHere is the bug demonstration in sql server 2008r2a. Check the Server Collation : should be SQL_Latin1_General_CP1_CI_ASb. Create a login: abcdc. Create a database: someDb with collation: Latin1_General_CI_AS_KS_WSd. Create a user: abcd in database someDb and map it to login abcde. Now open properties of login “abcd”.f. First open “User Mappings”.g. Now open “Securables”, you will get error exception.Here is the discussion:http://connect.microsoft.com/SQLServer/feedback/details/336208/collation-issue-raised-by-a-system-union-query-looking-at-securables-page-of-a-users-properties#detailsThis is a bug in sql server 2008 r2 I'm facing now. It should have a fix available for this. Can anyone tell me with which service pack is this covered? or how to overpass this.ThanksIgorMiTue, 25 Sep 2012 13:09:23 GMTIgorMi
