I have an exact copy of a database on 2 instances of SQL server (dev and test - dev is restored from test).There's a view that I select top 1000 rows from that runs extremely slow on both instances (DEV and TEST) however on DEV the execution plan specifies that I'm missing an index however in TEST the execution plan does not specify that I'm missing an index.

I've been running SQL 2005 Enterprise SP1 for some time. After installing SP2, I miss the "Database Mirror Monitor"-Feature. Where is it? Did MS kill the feature?

I am trying to use the Foreach Loop Container. When I open the container for edit on the Collection page, the Foreach Item and Foreach File enumerators are not listed in the drop down.
I have installed SQL Server 2005 Developer Edition. If there something else I need to install?
I appreciate any help provided

How can i enable my fulltex change-tracking and update-index in my table?
I recreated my fulltext catalog and start the full population, but although my fulltext index status shows active, my full-text change-tracking and the update index were disabled. - and I don't know how to enable them.
Thanks in advance
Hi,
I run a nightly dbcc checktable on order_header and today I see this error occurs.
Table error: Table 'ORDER_HEADER' (ID 203147769). Missing or invalid key in index 'PK_ORDER_HEADER' (ID 4) for the row:
Server: Msg 8955, Level 16, State 1, Line 1
1. I have no idea what caused it?
2. How do I fixed this online as the application is 24/7?
3. I did try to dbcc reindex but it failed reporting that can't create index because of duplicate in primary index key????
Please show me a way to fix this.
Thanks

One of the table that is in a merge replication somehow is missing anindex. Strangely, only the table in one of the subscriber of the mergereplication is missing the index; another subscriber and the publisherof the merge replication don't have this problem.How should I add the missing index back to that table? My understandingis that making structural change on a table that is inmerge-replication is different from making change on a table that isnot merge-replicated. For example, when we need to add a column into atable that is being merge-replicated, we must add the column bychanging the attributes in the properties of the published article(table) instead of simply using CREATE INDEX command. I am wonderingwhether there is a similar restriction on adding an index onto a tablethat is merge replicated.I have already added the index back to the table anyway. I am askinghere just in case doing this may get me into a problem later on.Thanks in advance for any info.Jay Chan

View 2 Replies View RelatedI'm in the process of trying to optimize a stored procedure with many queries. The execution plan provides a missing non-clustered index on nearly every query, and they're all fairly similar. The only real difference between them are what's in the INCLUDE statement. The two key columns are listed in every missing index. Let's say each query is approximately 5% of the total batch and 90% of the queries all fall into the category I listed above. How should I go about creating the missing indexes? Create all of the missing indexes or create one generic one that has all the INCLUDE columns? Create a minimal index with just a few of the common INCLUDE columns?
Here's an example of what I'm talking about with the missing indexes:
/*
USE [DB]
GO
CREATE NONCLUSTERED INDEX [<Name of Missing Index, sysname,>]
ON [dbo].[TABLE_1] ([COLUMN_A],[COLUMN_B])
INCLUDE ([C4ABCD],[C4ARTX],[C4ASTX],[C4ADNB],[C4AFNB],[C4BKVA])

I want to know the missing records in my table.
OUTPUT IS. 3,7,9
how can i do that using sql query.
I have one table with many records in the table. Each time a record is entered the date the record was entered is also saved in the table. I need a query that will find all the missing records in the table. So if I have in my table:
ID Date Location
1 4/1/2015 bld1
2 4/2/2015 bld1
3 4/4/2015 bld1
I want to run a query like
Select Date, Location FROM [table] WHERE (Date Between '4/1/2015' and '4/4/2015') and (Location = bld1)
WHERE Date not in
(Select Date, Location FROM [table])
And the results would be:
4/3/2015 bld1
I have table with column having values 1,2,3,5,6,10.

Am witnessing a very strange issue when i try to insert some records . I get the message in the SSMS like 5,10 etc rows affected. When i check for the same records in the table none of them is present.
This problem then automatically goes away after some time and all get backs to normal. I only have the access to that database no other user have the access. Totally confused about the all of a sudden new behavior of the database.

I have a transaction number in my mapping table. I have a matching transaction number in my PDHist table. Sometimes I have matching transaction numbers in my PD table, but not always. This is causing no records to be returned. I have a One to Many relationship between my mapping table and both PD and PDHist.
Also, I need to check for nulls in my foreign exchange table.I can’t post the SQL because this is a classified project. However, it should be something like this, I think.
IIf(IsNull([Redem]![FX Rate]),([PDHist]![Remaining Balance]+[PD]![Closing Balance(TC)]).
The addition isn’t working. I think with a small push I can get this straightened out.
I'm a little bit unsure...
declare @t table
(col1 varchar(10),
col2 varchar(10),
col3 varchar(10),
col4 varchar(10) )
insert into @t values ('A123', 'Test', '','')
insert into @t values ('', 'Test 1', 'Y','N')
[Code] ...
Which comes out as
col1 col2 col3 col4
(No column name)
A123 Test
1
Test 1
Y N 0
Y N
0
A125 Test
1
Test 9
Y N 0
N Y
0
but what I would like is col 1 populated As A123 until it hits A125 then populated A125 etc. I was thinking about using the iff but not getting anywhere fast.
How do I get the below scenario:
EmpID DepID
12 2
17 3
17 2
13 3
Every Employee should be in Department 2 and 3 (as example EmpID = 17 has DepID 2 and 3 from above table). But when any of the employees either exists only in any one department (as EmpID = 12 has only DepID = 2), then a new row should be added to the table for that employee with that missing DepID.
Desired Output:
EmpID DepID
12 2
17 3
17 2
13 3
12 3
13 2
In a t-sql 2012 sql update script listed below, it only works for a few records since the value of TST.dbo.LockCombination.seq only contains the value of 1 in most cases. Basically for every join listed below, there should be 5 records where each record has a distinct seq value of 1, 2, 3, 4, and 5. Thus my goal is to determine how to add the missing rows to the TST.dbo.LockCombination where there are no rows for seq values of between 2 to 5. I would like to know how to insert the missing rows and then do the following update statement. Thus can you show me the sql on how to add the rows for at least one of the missing sequence numbers?
UPDATE LKC
SET LKC.combo = lockCombo2
FROM [LockerPopulation] A
JOIN TST.dbo.School SCH ON A.schoolnumber = SCH.type
JOIN TST.dbo.Locker LKR ON SCH.schoolID = LKR.schoolID AND A.lockerNumber = LKR.number
[Code] ....
In SQL Studio, I can go to the restore window and the click "verify backup media". This would check the restore plan listed in this window and check if some of the file are missed.Is there any way to reach this with TQSL? I know there is a "restore verify" command, but this will only verify one backup/file and not the complete restore path. I'm looking for a TSQL solution which is able to control that all necessary backup files are still present on the file System and not moved or deleted (e.g through cleanup task).
View 3 Replies View RelatedI have two xml queries that take long: the 1st query takes about 5 minutes (returns 700 rows) and the 2nd query takes about 10 minutes (returns 4 rows). The total rows in the table is about 2 million. There are three secondary indexes: Property, Value and Path in addition to the clustered index on CardID and Primary XML index. Here is the table definition:
CREATE TABLE [dbo].[Cards]
(
[CardId] [int] NOT NULL,
[Card] [xml] NOT NULL,
CONSTRAINT [PK_dbo_Cards_CardId] PRIMARY KEY CLUSTERED
([CardId] ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
[code]...
Looking at the execution plan, the query uses the Primary XML Index even if I add any of the secondary xml indexes. My question is why does not the optimizer use the Property 2ndary index instead of the Primary XML Index? Microsoft recommends that creating a Property index for Value() method of the xml datatype would work to provide a performance benefit. What would be another alternative to make the query run faster?
I would like to completely understand the difference between index rebuild Maintenace plan and the customized script.Maintenance Plan rebuilds every single index.It will take the long time as it checks every index.If we use a custom script as a job, it will rebuild the index which has fragmentation >30%.So that, the job will not take much time.

1) don't include an ID column,
2) don't use the start date/end dates in the data or
3) use cursors, which are forbidden in my environment.

Now today I check Index Fragmentation I saw that many cluster and Non cluster Index are avg.Fragmentation is around 99 % I thought that in Identity column record is always inserted at bottom so there is no fill factor assigned to it.
So in this case Do I need to set Fill factor for Cluster and Non Cluster Index?
If Yes Then For PK How much - 95 % or what? and same for Non cluster or It should around 85 to 90

View 9 Replies View RelatedWe have a new database with cdc enabled on all of its tables. This causes the index maintenance task to fail with following message:
"Executing the query "EXEC DBName.dbo.IndexDefrag_sp" failed with the following error: "The unique index 'PK_TableName' on source table '[dbo].[TableName]' is used by Change Data Capture. To alter or drop the index, you must first disable Change Data Capture on the table. The transaction ended in the trigger. The batch has been aborted.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly" We would like to run the index maintenance without losing the cdc data. We plan on installing SP2 on SQL Server 2008 R2 soon, would that solve the issue? Disabling the cdc prior to index maintenance and then re-enabling back upon completion; would delete the data as I found in most discussions, but we would like to retain it.
