| I have noticed that one of our SQL Server 2005 databases is extremely slow. I noticed that the LDF file is 25GB in size. I realized that the database did not have a maintenance plan set up, which is the root of the problem.My question is about the strange behavior that I observed while the database was in that state. When I right-click and view properties of one of the tables I see that the row count is over 4B, however when I run count(*) query it returns 13K. Why such a discrepancy?Thanks,Alec |

| FYI, the number of rows displayed in the table properties is 4294982522.The output of "select @@version" is:Microsoft SQL Server 2005 - 9.00.4035.00 (Intel X86) Nov 24 2008 13:01:59 Copyright (c) 1988-2005 Microsoft Corporation Standard Edition on Windows NT 5.1 (Build 2600: Service Pack 2) |
