Is It Possible To Save And Force A Plan?
Jul 23, 2005I have a complex query (16 table join) that until five days ago took 30sec to run. It now takes eight hours. I restored a backup of thedatabase from five days ago and the query plans are completelydifferent for the same exact query. Five days ago the final estimatedrow count is 1.6M now it is 1.7E+10 OUCH! The amount of data added inthose five days is insignificant (percentage wise). I rebuilt all theindexes using DBCC DBREINDEX with no change in the plan or results. Isthere anyway to save the query plan (from the backup) and run itagainst the new data?TIA,Tracy

SQL 2012 :: Check Query Execution Plan Of A Store Procedure From Create Script?
Jun 17, 2015Is it possible to check query execution plan of a store procedure from create script (before creating it)?
Basically the developers want to know how a newly developed procedure will perform in production environment. Now, I don't want to create it in production for just checking the execution plan. However they've provided SQL script for the procedure. Now wondering is there any way to look at the execution plan for this procedure from the script provided?

View 2 Replies View RelatedSQL Server 2012 :: How To Rearrange The Execution Plan Manually
Nov 27, 2014I have 2 tables,
1. Need
2. NeedCategory
Need table has clusted index on needid column and NeedCategory have composite clustered index on needid and categoryid.
Now take a look on following query and execution plan for the query.
SELECT N.NeedId,N.NeedName,N.ProviderName
FROM dbo.Need N
JOIN dbo.NeedCategory NC
ON nc.NeedId = n.NeedId
WHERE IsActive=1
AND CategoryId= 2
ORDER BY NeedName
* Clustered index scan on need table is happens for Isactive= 1.
* Clustered index scan on needcategory table is happens for CategoryId=2
My question is,
1. Why scan happens before the join occurs? if it happens after join then the filter would be lighter. Even if optimizer chooses the scan to execute first.
2. Is there any chance to rearrange the execution plan manually?

SQL Server 2012 :: Sort In Execution Plan - Delete Statement?
Nov 11, 2014I'm new to using SQL Server. I've been asked to optimize a series of scripts that queries over 4 millions records. I've managed to add indexes and remove a cursor, which increased performance. Now when I run the execution plan, the only query that cost is a DELETE statement from the main table. It shows a SORT which cost 71%. The table has 2 columns and a unique index. Here is the current index:
ALTER TABLE [dbo].[Qry] ADD CONSTRAINT [Qry_PK] PRIMARY KEY NONCLUSTERED
(
[QryNum] ASC,
[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = ON, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]

Question: Will the SORT affect the overall performance? If so, is there anything I should change within the index that would speed up my query?

**The lookup table b for column id and country are always not null values, and both of them are the keys to join table a. This is because same id and country can have multiples rows in table a due to update date and posting date fields.
example table a
id country area
1 China Asia
2 Thailand Asia

4 Japan Asia
example table b
id country area

SQL Server Admin 2014 :: Estimated Query Plan For A Stored Procedure With Multiple Query Statements
Oct 30, 2015When viewing an estimated query plan for a stored procedure with multiple query statements, two things stand out to me and I wanted to get confirmation if I'm correct.
1. Under <ParameterList><ColumnReference... does the xml attribute "ParameterCompiledValue" represent the value used when the query plan was generated?
<ParameterList>
<ColumnReference Column="@Measure" ParameterCompiledValue="'all'" />
</ParameterList>
</QueryPlan>
</StmtSimple>
2. Does each query statement that makes up the execution plan for the stored procedure have it's own execution plan? And meaning the stored procedure is made up of multiple query plans that could have been generated at a different time to another part of that stored procedure?
SQL Server 2012 :: Date / Time Calculations For Work-plan Times?
May 31, 2015I have a table that stores working hrs, such as
RecID,StaffID,StartDate,EndDate
17,969,2015-05-18 00:00:00.000,2015-05-18 06:00:00.000
18,969,2015-05-18 18:00:00.000,2015-05-19 06:00:00.000
19,969,2015-05-19 18:00:00.000,2015-05-20 06:00:00.000
20,969,2015-05-20 18:00:00.000,2015-05-21 06:00:00.000
21,969,2015-05-21 18:00:00.000,2015-05-22 06:00:00.000
22,969,2015-05-22 18:00:00.000,2015-05-23 06:00:00.000
23,969,2015-05-23 14:00:00.000,2015-05-24 08:00:00.000
24,969,2015-05-24 22:00:00.000,2015-05-25 00:00:00.000
So working times can go over midnight, there can be more than one working period in a day etc.
For this staff member the summary of the weeks work will be
18/05/2015 - 12 hrs
19/05/2015 - 12 hrs
20/05/2015 - 12 hrs
21/05/2015 - 12 hrs
22/05/2015 - 12 hrs
23/05/2015 - 16 hrs
24/05/2015 - 10 hrs
Now for the complicated part, a person can take absence(sick,holiday,other) for any part of a day or whole day(s). For these absence periods only the worked time on that day needs to be negated off, not the whole period of time.
So for example
If this person
had a days holiday on the 22nd, shown in the HOLIDAY table as
StaffID,DateFrom, DateTo
969, 22/05/2015 00:00:00.000,22/05/2015 23:59:59.000
A Leave of Absence on the 20th, shown in the LEAVE table as
StaffID,DateFrom, DateTo
969,20/05/2015 12:00:00.000,20/05/2015 16:00:00.000
And was off sick on the morning of the 19th, shown in the SICKNESS Table as
StaffID,DateFrom, DateTo
969, 19/05/2015 00:00:00.000,19/05/2015 11:59:59.000
Now the Summary table should now show
18/05/2015 - 12 hrs
19/05/2015 - 6 hrs
20/05/2015 - 12 hrs
21/05/2015 - 12 hrs
22/05/2015 - 0 hrs
23/05/2015 - 16 hrs
24/05/2015 - 10 hrs
The 'Leave of Absence' on the 20th had no effect on the total for the day as it was between planned work times. how to do this within T-SQL, as simple as possible as I've got to had this code over to other staff members to maintain, who have not had much SQL experience yet?
I've tried doing it as a temp table, with dual insert/select commands, splitting the times over midnight, which partially worked but missed some of the combinations.
SQL 2012 :: Force Encryption With DoD Certificate
Sep 15, 2015I have a SQL Server 2012 Standard and needed to fulfill a requirement to set Force Encryption on the Server with a DoD Certificate.
I will be altering my client connections to use Encrypt=True; TrustServerCertificate=True (The client is a .Net Web Application).
The OS is where SQL Server 2012 Standard resides is Windows 2008 R2 DataCenter Service Pack 1 64-bit.
What I am needing to know is where do I get the DoD Certificate from? and Do I just install it on the server where SQL Server resides?
SQL 2012 :: Generate Scripts Result In Order Of Tables And Then Stored Procedures In Server
Sep 10, 2014I have created one table and one stored procedure for to insert/delete/update the data in that table.
So,I was trying to move the scripts from one database to another by Generating Scripts options in SQL Server.
Generating Scripts:
Object Explorer --> Databases --> Database --> Tasks --> Generate Scripts
The generated script output is in a order of stored procedure first and then table.
REQUIREMENT: My stored procedure is dependent on table. So, I need the table script first and then stored procedure.
Note: I can generate two separate scripts for table and stored procedure, But in a just curiosity to know, Is there any way, can we re order the Generate Scripts output in SQL Server.
SQL 2012 :: Enabling SSL Encrypted Connections Without Using Force Encryption Option
Apr 1, 2015I have a customer who is looking to encrypt their applications connection to the back-end SQL server. I've gotten a valid certificate for the server from a trusted CA, and it's installed on the server (shows up in Personal certificates in the Certificate MMC when selecting the computer) and I can choose it in the drop down on the certificates tab of the SQL Network protocols properties in Configuration Manager.
Now, my question: If I select the certificate but do NOT enable the "Force Encryption" option, the client will be able to request encryption on their end, and the connection will then be encrypted. If the client (other applications) do NOT request encryption, they will still be able to connect, but their connection will be un-encrypted. URL....
Lastly, I could've swore I had found some information indicating that some methods of establishing a connection to SQL can fail when Force Encryption is enabled, as the method doesn't support SSL encryption.
Query Plan In SQL Server 2005 SP2
Aug 14, 2007Hello,
The query included at the end of this post seems to use the 'wrong' index when executing and takes 2+ minutes to run. When I provide an index hint, it runs in under 1 second. This happens in both the Production and Development environments; both servers run SQL Server 2005 SP2.
When I run both the queries together in Query Analyzer (or SSMS), the Query Cost (relative to the batch) value for the query with the index hint = 83.24%.
Profiler stats for Original Query:
Duration = 130484 ms
CPU = 111141 ms
Reads = 85470
Profiler stats for Index Hint Query:
Duration = 64 ms
CPU = 687 ms
Reads = 5558
Statistics are updated every night (w/Fullscan)
Indexes are rebuilt/defragmented daily based on fragmentation levels.
What am I missing here/how do I fix this performance issue?
Doesn't Profiler take into account the "Subtree Cost" for the Index Seek (which Query Analyzer & SSMS consider to be so expensive)? What Events/Columns do I need to include in the Profiler trace to see this statistic when the query is executing?
Thanks much,
Smitha

Query Plan SQL Server 2008
Apr 30, 2008I have a person table with 1 billion rows on it, partitioned equally at 10 million rows per partition. The primary key constraint is a composite of an identity column and ssn( char(11) ) with the partitioning column built on the SSN.
This is built on my home grown workstation:
Microsoft 2008 Server 64 bit, Microsoft SQL server 2008 64 bit, Intel 2.66 quad core, 8 gb ram, Os/ raid 1, data on 6 drives hardware/software raid 50, transaction logs on 4 drive raid 10, all drives sata II/ 3gb burst.
I have updated statistics on the table and I have 2 queries that give clustered index seek , one never comes back before I get impatient, the other comes back instantly, and the showplan looks the same for both queries.
SELECT *
FROM Person
WHERE PersonKey > -1 and SSN = '219-09-3987'
AND
SELECT TOP 100 PERCENT *
FROM Person
WHERE PersonKey > -1 and SSN = '219-09-3987'
Incidentally the query with the top 100 percent is the one that returns instantly.
I am puzzled
1) Why the estimated plan looks the same
2) Why a top 100 Percent query is faster than one without it

SQL 2012 :: SSRS - Force Report To Use Columns Returned From Stored Procedure?
Jul 10, 2015I have a stored procedure which returns a result set as follows:
(Headers)Total,WV1,WV2,WV3,WV4,WV5.....
(Example data) "Some total name",1,2,3,4,5.....
The WV1, WV2, WV3 column names will be different depending on parameters passed to the stored procedure. In other words, the column names or number of columns aren't fixed (apart from "Total").
What I would like to be able to do is to just force SSRS to use the column headers supplied by the stored procedure as the column names in the report.

SQL Server 2008 :: Query To Generate Report Of Locked Account
Jan 9, 2011Just wondering if there is any query which can give me report of locked account in SQL 2008. I know there are options like:-
1) Can go in ssms--security--account and right click and select status. This is applicable to individual account.
2)SELECT LOGINPROPERTY('accountid', 'IsLocked'). Also applicable to individual account
3) SELECT name,type_desc,is_disabled,modify_date,default_database_name from sys.server_principals order by type_desc
Generate the report but give the informatio as is_disabled. But I think is_disabled <> is_locked.
SQL Server 2014 :: Query Plan For Partitioned Views Not Running As They Should
Mar 29, 2015I've been using partitioned views in the past and used the check constraint in the source tables to make sure the only the table with the condition in the where clause on the view was used. In SQL Server 2012 this was working just fine (I had to do some tricks to suppress parameter sniffing, but it was working correct after doing that). Now I've been installing SQL Server 2014 Developer and used exactly the same logic and in the actual query plan it is still using the other tables. I've tried the following things to avoid this:
- OPTION (RECOMPILE)
- Using dynamic SQL to pass the parameter value as a static string to avoid sniffing.
To explain wat I'm doing is this:
1. I have 3 servers with the same source tables, the only difference in the tables is one column with the server name.
2. I've created a CHECK CONSTRAINT on the server name column on each server.
3. On one of the three server (in my case server 3) I've setup linked server connections to Server 1 and 2.
4. On Server 3 I've created a partioned view that is build up like this:
SELECT * FROM [server1].[database].[dbo].[table]
UNION ALL SELECT * FROM [server2].[database].[dbo].[table]
UNION ALL SELECT * FROM [server3].[database].[dbo].[table]5. To query the partioned view I use a query like this:
SELECT *
FROM [database].[dbo].[partioned_view_name]
WHERE [server_name] = 'Server2'
Now when I look at the execution plan on the 2014 environment it is still using all the servers instead of just Server2 like it should be. The strange thing is that SQL 2008 and 2012 are working just fine but 2014 seems not to use the correct plan.
SQL Server 2008 :: Query Plan Output List (IsBaseRow)
May 6, 2015Looking at an execution plan today I noticed something I've not seen before. The plan includes a non clustered index seek, followed by a RID lookup on the heap. The output list for the index seek contains the expected "Bmk" column (in this case "Bmk1473"), but also includes "IsBaseRow1475". This isn't a column from the table.

Jun 17, 2015Is it possible to check query execution plan of a store procedure from create script (before creating it)?
Basically the developers want to know how a newly developed procedure will perform in production environment. Now, I don't want to create it in production for just checking the execution plan. However they've provided SQL script for the procedure. Now wondering is there any way to look at the execution plan for this procedure from the script provided?
SQL Server 2008 :: Left Joins And Query Plan Compile Times
Mar 8, 2015We have a view with many left joins. The original creators of this view might have been lazy or sloppy, I don't know. I have rewritten the query to proper inner joins where required and also nested left joins.
So rather then the following exemplary fragment
select <many items>
from A
left join B on B.id_A = A.id
left join C on C.id_B = B.idthis now looks like
select <many items>
from A
left join (B
join C on C.id_B = B.id
) on B.id_A = A.id
Compilation time of the original view was 18s, of the new rewritten view 4s. The performance of execution is also better (not counting the compile of course). The results of the query are identical. There are about 30 left joins in the original view.
I can imagine that the optimizer has difficulty with all these left joins. But 14s is quite a big difference. I haven't looked into detail in the execution plans yet. I noticed that in both cases the Reason for Early Termination of Statement Optimization was Time Out.
