I want to remove the rows where A and B are the same as on the previous row. So rows 2, 3, 7 and 9 should be eliminated. Note that A and B can have the same values multiple times, just not in succession in the extract. I've tried ranking but I can't figure out how to keep it from lumping all the values of A and B in the same group. The following incorrectly eliminates rows 5 and 8:
;with data as (
select 1 as A, 1 as B, '2015-01-01' as DTE union
select 1 as A, 1 as B, '2015-01-02' as DTE union
select 1 as A, 1 as B, '2015-01-03' as DTE union
select 2 as A, 1 as B, '2015-01-04' as DTE union
[Code] .....
Of course the real data has many columns and multiple data types that can have nulls. I just want get the row when anything changes. Is there a slick way to do this in SQL?
I like to backup the stored procedures' code used in my databases. So I created this Script:
/* IF OBJECT_ID('[Monitor].[dbo].[Procedurecode]') IS NOT NULL DROP TABLE [Monitor].[dbo].[Procedurecode]; */ DECLARE @db nvarchar(50), @strSQL nvarchar (100) IF CURSOR_STATUS('global','cur1')>=-1 BEGIN DEALLOCATE cur1 END
[code]....
Problem is (and I seem not to be the only one with tis) described here:
"If the executed string contains a USE statement that changes the database context, the change to the database context only lasts until sp_executesql or the EXECUTE statement has finished running." There is nothing magical in SQL server that knows you intend a series of dynamic sql commands to be part of a single job running in a single context. You have to build the entire string for the job you want to execute."
I am in process to develop TSql code to identify change in data.
I read about Binary_checksum and hashbyte. Some people say hashbyte is better than binay_checksum as chances of collision are less.
But if we may consider following, chances exist in hashbyte too. My question is what is the best way to compare data to identify change (I can't configure CDC) ?
We are planning to convert or change all existing Traces to Extended Events in SQL server 2012. What is the procedure to convert custom traces. We have already created some below custom traces: like this we are planning to convert for all servers.
How to reset the value of the change tracking anchor id?
CHANGE_TRACKING_CURRENT_VERSION()
It's a bigint that increments on every DML operation and I just wondered how you could reset it back to zero. Turning change tracking off and on doesn't seem to do it.
it runs over night, pulls 10.5m rows. Inserts into a table, from a select (so "insert...select", rather than "select into"), from many tables, grouping on a max. It's complex. During the day, it runs fine - maybe 25 minutes. At night it *sometimes* runs fine, but then sometimes takes 4hours.Checking this morning there were 230 threads open for this one query. Checking sys.dm_os_tasks and sys.dm_os_waiting_tasks there were no other wait types on that session_id. None at all. Checking activity monitor, most of the existing threads were suspended on the insert.
There are 24 cores, but NUMA'd. We have maxdop on the server of 8. The maxdop option on the query is 12, just to speed up the select. Index and Stats refreshed daily. We've eight identical tempdb data files, on a separate spindle. Checking those, they are filling up using the round robin correctly
Would the delay be due to SQL trying to combine so many 'select' threads into one 'insert' thread (as it can't insert in parallel; 2014 can, apparently. Upgrades not available!)Should i change the SP to run the select into a temp table (table variable?) with a maxdop of 12, then do the insert into the actual table using a maxdop of 1. Checking the execution plans for a table variable implies the subtree cost comes down from 2.5m to 357k. What's best - temp table or table variable?
As the title suggests we are looking to change the service account of a SQL mirror implementation. I will be using the same account on all 3 servers involved in the configuration.
I know each server requires the account of the other two adding but as this will be the same account I assume this doesn't apply?
Also for mirrored databases already set up would I need to reconfigure the security for each one?
did VARCHAR(20) SELECT top 10 CAST(did AS INT) FROM table Msg 245, Level 16, State 1, Line 3

We have 2 node sql 2012 cluster and we have a scenario where domain,IPs,Hostanmes and SQL network name are changing.
1> Can SQL cluster role be brought online by changing the sql network name and its IP once windows team reconfigure the OS cluster or there will be any challenges.
2>should I uninstall sql cluster on both nodes then windows will destroy OS cluster and they then they need to change IP,hostname and domain and then fresh installation of sql cluster
Version: SQL SERVER 2012 enterprise edition and SP2.
Due to one of the security reason, I have changed default port 1433 to another port number in configuration manger tools->protocols for MSSQLSERVER->TCP/IP --> IP ALL section mention another port number.
After restarted service, SQL SSMS able to connect server itself and new port number also LISTENING.
But SQL client SSMS not connected to one of the PC side after changing default port.
why when I make a change to a foreach loop container in a SSIS package it does not save?
I am trying to change the base file name and if I change it through either the edit or properties windows, the changes does not save. Fore example i change the Files: or File Spec: from oldfile*.txt to newfilename*.txt and when I save and og bak into the edit area to confirm the change, the Files: section shows as "oldfile*.txt.
I store files in db in sql server 2008 by filestream. But when a column would be added to table which have filestream, properties of table would be changed. by every things change on table, retrieve files will faced to error. but store process work probably.
and filestream filegroup at following address will be empty. why?
Right click on table --> properties --> storage --> filestream filegroup
In an existing SSRS 2012 report, I have a requirement for a user to be able to select by multiple school(s) and/or multiple grade(s). This is fine except certain schools like elementary have grade levels of KG to 06, Middle school has grades of 06 to 09 and high school has grades of 10 to 12. Thus for example, if a user has initially selected grades 11 and 12 and then they select an elementary school that has grades KG through 06, the 'grade level' selection would need to change.In other words, I am thinking of initially having the available and default values for the parameter called 'Grade' set to KG through 12. However if a school is selected that only has specific grade levels like elementary school, how can I override the original grade level and only allow the user to select grades that the particular school contains?
We were recently acquired and need to move our existing SSRS 2012 mail server from our internal SMTP service. The internal service doesn't need to have a 'real' account to send email out. Everything seems to be setup and running under the internal service.I think I need to change the Email Settings information in "Reporting Services Configuration Manager". Namely the Sender address and SMTP Server fields. But without actually making these changes, I don't see where it is going to ask for the password. Really hate to make changes on a production server.
Do I need to change the "Log On As" account in the "SQL Server Configuration Manager" as well? If so, does this need to be the same account as used in the Sender Address (above)?. there is a lot of ink about making additions to the "rsreportserver.config" file. Our existing file does not have any of these entries.
is there a way to change SSMS 2012 default query save location?
Scenario:
1. Open SSMS 2. Create new query 3. Click Save
I see "DocumentsSQL Server Management Studio" folder, but I want to change it to be "d:". How do I do this? I tried:
1. [URL]- in folder "DocumentsSQL Server Management StudioSettingsSQL Server Management Studio" there is a file NewSettings.vssettings, setting it to "d:" or "d:" didn't work.
2. Changing HKEY_CURRENT_USERSoftwareMicrosoftMicrosoft SQL Server100ToolsShell VisualStudioProjectsLocation didn't work too. There is no "Shell" under "110Tools"
Did I do something wrong, or is there another way?
I am using SQL Server 2012 and to me a part of data captured by CDC is not making sense.
I have a table called 'Schema.Table1', and I enabled CDC on it by running 'sys.sp_cdc_enable_table'. I see that a table called 'cdc.Schema_Table1_CT' got created which now gets an entry when ever I Insert, Update or delete a record in the original table.
Till this point every thing works fine.
My original Table has a NOT NULL INT column called 'AuditTrackerUserID' with a default value of 1996. My application does not provides a value for this column, but because the column itself has a default value, records get inserted without error.
When I try to execute the following Query I see multiple records with __$operation of 3 and 1.
SELECT * from cdc.Schema_Table1_CT where AuditTrackerUserID IS NULL
My expectation is that I should not ever see any record returned by this query because AuditTrackerUserID is a not null column, but I do.
