How do I shrink the physical Transaction Log file when it's the principal in a mirror? What does the secondary server have in the SQL Server error log? You should have a few error log messages dictating what happened to cause the mirroring session to be suspended. |

Why use separate databases for high traffic/volume tables? Also, the concurrency gains from separating reporting workloads vs. OLTP workloads can be significant. Not to mention the handful of points that @AaronBertrand brought up. In order to know they "why" of that database design, you need to talk to the developers that designed it. |

Clustered vs Nonclustered Index The gains that you will see from having the predicate on the index as well as filtered statistics will depend largely on how filtered it is. Without seeing more information regarding your table and data, it is hard to give exact recommendations. But my comments (and answer) are food for thought. |

Clustered vs Nonclustered Index What RDBMS are you using? SQL Server? This sounds like a good candidate for a filtered index. Does the application really do a full column select ( *)? Unless your nonclustered index is covering, you'll have key lookups. |

IIS takes longer to run queries than SMSS Capture the post execution plans of both the queries run through IIS and through SSMS. Post them here, if possible. But look for discrepancies and performance degraders. |

Migrating from SQL Server 2005 to SQL Server 2008 R2 on a different box +1 Great info. I personally revert to the SSIS solution. Between it's simplicity (it is extremely simple, even if you never work with SSIS), options, error handling, and reusability. Handles more than just logins and jobs for server-object migration. Thought worth mentioning. Again great answer, Aaron, as I've used to this process many times without a single issue. |

Unique Constraint with multiple null columns That's by design (msdn.microsoft.com/en-us/library/ms191166(v=SQL.105).aspx). What's your question? |

sql server 2008 error in working Did you install SQL Server Standard or Express? Also, is this a local instance you are connecting to or did you install SQL Server on a remote machine that you are now trying to connect to? |

SQL Server 2012, Network for: AlwaysOn Availability Group with AlwaysOn AlwaysOn Failover Cluster Instances @ElijahW.Gagne No that's not correct. If your driver doesn't support MultiSubnetFailover then you just need to set RegisterAllProvidersIP to 0 in your cluster so that only the online IP address is registered to prevent connection latency/timeouts. |
