SQL Server 2008 :: Usage Of Built-in Functions On Columns Ignores / Excludes Indexes On That Column?
May 25, 2015Somewhere i read..that in SQL Server...usage of Built-in Functions on Columns, makes query optimizer to ignore indexes on that column...!
So lets say we have table EMP with Emp_id and Emp_Name....
Also we have Non-Clustered index on Emp_Name.
So following query would NOT use Non-Clustered index on Emp_Name column.
SELECTLEFT(emp_name, 3) as emp3
FROMdbo.EMP
Is this true? i am using SQL Server 2008.
How To Find Fragmentation Of Indexes
Mar 27, 2008Hi
I try to find the percentage of fragmentation in the perticular table using the following table. For some tables it is getting the results but for some database tables it is saying the error in qurey even if I use same query. Is there any reason for that. Or is there any other way to find out the fragmentation of table. any help would be fine. Thanks!
SELECT a.index_id, name, avg_fragmentation_in_percent
FROM sys.dm_db_index_physical_stats (DB_ID(), OBJECT_ID(N'schema.tablename),
NULL, NULL, NULL) AS a
JOIN sys.indexes AS b ON a.object_id = b.object_id AND a.index_id = b.index_id;
GO
And is there any way to find out when did index rebuild occurs in perticular index or table. Thank you very much.

Multiple Columns Index/Key (does It Free Me From Creating A Single Column Indexes???)
Apr 12, 2007I hope i'm in the right place, but thanks anyway....
Actually i have 2 questions (regarding sql-server Indices/Keys):
1) I have an index, which is consisted of 4 columns.
I've read elsewhere that this index functions (as well) as an index (single column
index) on the first column of this multi-column index.
Does this mean that if i'd like to have (in addition) Indices on all of the 4 columns
seperately i need to define only 3???
2) I have a unique key consisted of multiple columns.
I'd like to save an index to this combination of columns as well (to speed up
things in DB...).
Does the definition of a multiple-columns key free me from defining the multiple-
columns index???
can anyone explain the main diference between Keys and Indices???

Indexes & SQL 2000 -&> SQL 2005 Upgrade
Jun 17, 2008Hi all,
Recently, I upgraded one of our database servers from SQL 2000 to SQL 2005. At the moment, all the databases are in 80 compatibility mode. I upgraded them based on the false pretenses that I could perform online reindexing right off the bat. Apparently, that isn't the case, and it requires switching to 90 compatibility. My question is if I switch to 90, will all indexes be invalidated/unusable? Or will I be able to switch to 90 and perform the online reindexing right away with no downtime?
We have a few 24/7 production VLDB's in the mix (one of which is on this newly upgraded server), and only reasonable downtime is possible. The largest window of downtime I have is about 10 PM - 5 AM with prior notice.
The upgrade was performed using SAN-based LUN's with a detach/reattach.
Thanks,
Matt
COLID Discrepancy In Syscolumns / Information_Schema.Columns - SQL Server 2000
Jul 20, 2005I ran the following query in Query Analyzer for a 7 column table.SELECT c.name,c.colid FROM syscolumns c WHERE c.id=925962375 ORDER BYc.colidThe results were:I_CSD 1X_STE_XML2I_USR_LCK4T_CRT_RCD5I_USR_CRT_RCD6T_UDT_RCD7I_USR_UDT_RCD8If I use the information_schema view (SELECT column_name,ordinal_position FROM information_schema.columns WHERE table_name ='CSD_XML') I get the same results.The problem is that the colids go from 2 to 4 and the colids gothrough 8 when there are only 7 columns.At one time there was another column in the table, but it has sincebeen dropped and isn't there anymore. It seems that the colids insyscolumns did not update when the column was dropped.Is this because of the way I dropped the column? Is there anything Ican do now that it has happened?
View 3 Replies View RelatedIndexes Messed After 2000 -&> 2005 Db Move
Jun 13, 2008Recently moved a couple of dbs from SQL 2000 -> SQL 2005 (different machine). Just restored the dbs on the new server from a full backup of the old one. Everything is fine but...
Some queries are returning out-of-order results (for records added since the migration). I tracked this down to the indexes. I completely rebuilt and reorganized the indexes (online) through the manager interface. This helped provide correct ordering for existing records, but new records added since the re index are still out-of-order.
Looking for a way to permanently fix the indexes so I don't have to constantly rebuild them.
Thanks.

Find Max Values From 3 Different Columns?
Mar 9, 2008Hi I want to find 3 different columns maximum values in one shot. Like I tried to use a reader to go through results but it kept coming back with index out of bounds. Right now to get it to work I got to use a ExecuteScalar() get the first columns max value and then open the connection again(since it seems after ExecuteScalar() it closes the connection) and then do the ExecuteScalar() again. Open the connection again and do the ExecuteScalar() again. Theres got to be a better way of doing this.

Cannot Find Columns From A Stored Procedure...
Jul 21, 2007I have an application that I inherited, and I have a annoying problem. We're using stored procedures to return most of our data, and occasionally we receive errors stating that a particular column cannot be found in the resulting data table. When I run the stored procedure against SQL Server I receive the expected output. What would make this random act happen, any ideas?
Also, I keep receiving errors stating that a connection is already open and needs to be closed before an action to the database is performed. I'm explicitly closing each connection in a finally block for every method in my data access code, so a connection should always be closed, right?
