| Maybe it's just a matter of style, but I've seen:<database>..<object> --OR--<database>.dbo.<object>Is there any difference in maintenance/performance (with and without ownership chaining on) between these two? |

| If the referencing user is dbo then the two methods should be identical. When an object owner is not specified SQL Server checks for ownership in the following order: 1. Owned by the current user, 2. Owned by dbo. If the object is owned by the dbo and the referencing user is not a member of the db_owner role SQL Server can eliminate the first check by specifying dbo as the object owner. So owner qualification would be preferred.JustinExpect 0x80040106 |
