Need to check a table for errors

Hi - please excuse my newness to this. I have a database with several tables and one of them is causing my application to lag really bad. I figure there is either not enough space or something is just wrong in general and i don't know what. Does SQL Server have a shortcut or easy way to test a table in the database?

Thanks =)If it is only giving performance troubles, I bet it is a large table (either many columns, many rows, or both). Look into the index tuning wizard in Enterprise Manager.|||Originally posted by Avernus

dbcc checktable(yourtable)?

Ok will try that.

I also forgot to mention that it has worked fine for a year and all the sudden is causing literally 5 minute lag periods.

Also you could check for fragmentation (it is good idea to do this sometimes):

DBCC SHOWCONTIG|||In Query Analyzer execute one of the queries your app issues after setting Show Execution Plan to ON (Ctrl+K.) The corresponding pane will show you how the Optimizer processed the request. Pay close attention to anything in RED there, as well as table/index scans.|||"Also you could check for fragmentation (it is good idea to do this sometimes):

I get an error trying to run this alone. I read something about having to include an Object ID with this command. Can you show me an example of how that looks written out for one table? Thanks, I appreciate this bigtime =)
