| I have a huge table (270 million records, 118 GB). I need to rebuild its PK index because it is too fragmented. Problem is that I don't have enough space for that. The transaction log will explode. Is there any trick that I can use? I know that Reorg will do the trick. But it's more than 50% fragmented. Doesn't it have to be rebuilt, not reorganized? |

| You'll need about 120GB of space in the transaction log file to rebuild it. There's no way around that unless you were to delete/move data.Your transaction log should be sized at least the size of the largest index so that a rebuild can occur. And if you have enterprise edition where ONLINE=ON is a feature, you'd need free space inside the mdf file that equals at least 125% of the size of the largest index.Tara KizerSQL Server MVP since 2007http://weblogs.sqlteam.com/tarad/ |
