Query Replica Directly Via SSMS?
Apr 3, 2015I know it is possible to use the secondary replica to pull data (application intent) etc..
But is there some way to query the replica directly via SSMS?

SQL 2012 :: Backup On Primary Replica In Case Of Secondary Replica Is Down
Jun 9, 2014I have 2 SQL Server replicas configured on SQL Server 2012 AlwaysOn. e.g. SQL1 & SQL2.
I have configured backup job on both SQL Server with the following statement. and the job occurs every 10 minutes.
•declare @DBNAME sysname,@sqlstr varchar(500)
set @DBNAME = 'dba'
IF (sys.fn_hadr_backup_is_preferred_replica(@DBNAME)=0)
BEGIN
--Select 'This is not the preferred replica, exiting with success';
[Code] ...
I turned off SQL2 for Windows maintenance. So there is only SQL1 is online. Afterwards. I checked the backup folder and didn't see any new backup files was created after SQL2 was offline. I rerun the job. It still doesn't backup database on the Primary Replica. Then I searched on SQL Server Book online. It says
Prefer Secondary
Specifies that backups should occur on a secondary replica except when the primary replica is the only replica online. In that case, the backup should occur on the primary replica. This is the default option.
According to what it says, it should backup on the Primary Replica.
SQL 2012 :: Existing Replica MDF File Size Increased In Size Than New Replica Install
Apr 14, 2015Here are my scenarios:
We have an application with replicated environment setup on sql server 2012 . Users will have a replica on their machines and they will replicate to the master database. It has 3 subscriptions subscribed to the publications on the master db.
1) We set up a replica(which uses sql server 2012) on a machine with no sql server on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 33gigs and ldf has grown to 41 gigs. I went to sql server management studion . Right click and checked the properties of the local database. over all size is around 84 gb with little empty free space available.
2) We set up a replica(which uses sql server 2012) on a machine with sql server 2008 on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 49 gigs and ldf has grown to 41 gigs. I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
3) We set up a replica(which uses sql server 2012) on a machine with sql server 2012 on it. We have dropped the local database and recreated the local db and did the initial synchronization using replmerge tool. The mdf file has grown to 49 gigs and ldf has grown to 41 gigs. I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
Why it is allocating the space differently? This is effecting our initial replica set up times.
Query View Vs Query Tables Directly
May 19, 2008Greetings,
I recently started working with a database that uses several views, none of which are indexed. I've compared the execution plans of querying against the view versus querying against the tables and as best I can tell from my limited knowledge the two seem to perform equally. It seems to me that having the view is just one more thing I need to keep track of.
I've done some google searches but haven't found anything that really tells me which performs better, querying the view or the tables directly. Generally speaking which is better?
Thanks in advance for your replies.

How Can I Directly Include A Square Root In A SQL Query
Dec 17, 2006I have an ASP.NET application where I need to filter the records returned from a SQL query using a calculated distance to a point that is set by the user. To do this directly, I would need to include a square root of an expression in the SQL query. It seems like I should be able to do this by writing my SQL query something like:
SELECT SQRT(expression ....) AS distance, column2, column3 ... FROM mytable WHERE distance < 50
Unfortunately, SQL queries apparently don't like the SQRT function. I am using .NET 2.0 with VS2005 and a MS Access backend (that will soon be moved to SQL/Server).
As an alternate, maybe I can query the data into a temporary record set with a extra field for distance and then step my way through the temporary record set and replace the values in the distance field with a calculated distance. Once the temporary record set is prepared, then I would delete the records that don't pass the distance requirement or otherwise hide them and bind the data to a gridview control.
Thanks,
David
SQL 2012 :: Save Query Results Directly Using Variables And Date / Time
Sep 1, 2015I wonder if it is possible to run a stored procedure and save the results directly to a file in a predetermined directory
As an example I have created a (simple) stored procedure:
USE CovasCopy
GO
CREATE PROCEDURE spTryOut
(
@LastName as NVARCHAR(50)
, @FirstName AS NVARCHAR(25)
[Code] ....
What I would like to add is a (or more?) lines that save the results in a file (csv/txt/tab?)
The name I would like the file to have is "LastName, FirstName, Date query ran, time (HHMMSS?) query ran"
The directory: D:SQLServerResults

Mar 7, 2007When I create a new query window in SSMS 2005 (SP2) , I do not have any available database in de SQL Editor pane. Though in the Object Explorer window below, I can access all objects of all databases. The only way to query a table is by using the 'Open Table' feature in the Object Explorer window, then right-click on Pane-->SQL .
I also can open a stored procedure, but not modify it as the SQL Editor pane is disabled.
The SQL-Editor pane is available for all the other servertypes (Analysis, Reporting, Integration).
All services all started.

SQL 2012 :: Pasting Query Results Into XL From SSMS
Mar 13, 2014Previous to 2012, grid results from SSMS queries pasted into Excel beautifully and were easy to format.in 2008, The results from this query pasted into a spreadsheet with the query contained in a single Excel cell:
(sample - not the whole script)
select top 300
Avg_CPU_Time
,Total_Physical_Reads
,convert(datetime,Last_execution_time) as Timestamp
,Stored_Procedure
,Query_text
from dbadmin.dbo.History_CPU_IO_ByQueryAndSP
This was wonderful. I could deliver to developers wonderfully tidy reports on query resource usage with timestamps along with which stored procedure the queries came from.
Can't do that in SSMS 2012. Try it. It's a disaster. The Query_text, when pasted, spreads across multiple Excel columns, including the ones designated for other data. The result is totally unreadable.how to make the query_text stay in it's own cell? I've tried converting query_text to varchar and ntext. Same results.
Performance Difference Between Query Executed Through ASP.NET And SSMS
Sep 18, 2007I have also posted this in microsoft.public.sqlserver.programming.
I have a query which, depending on where I run it from, will either take 10 milliseconds or 10 seconds.
The query works perfectly when run in SQL Server Management Studio... in my database of around 70,000 items it returns the results in around 10ms. It uses all my indexes and indexed views correctly.
However when I run the identical query from my ASP.NET application, it takes around 10 seconds... 1000 times longer.
Looking at it in Sql Server Profiler I can't see any difference in the query, except from ASP.NET it needs 62531 reads and from SSMS it needs only 318 reads. If I copy the slow running ASP.NET query from the profiler into SSMS, then it runs quick again. The results returned are the same.
I have provided more details of the query below, but I guess my real question is: What is the best way to debug this? I'm not an expert with SQL Server, so any pointers on where I should start looking to find the difference in how the query is being executed would be a great help.
The query is of the form:
WITH RowPost AS
(
SELECT
ROW_NUMBER() OVER(ORDER BY DateCreated DESC) AS Row,
ItemId,
Title,
....
FROM
Items_View WITH(NOEXPAND)
WHERE ItemX >= @minX AND ItemX <= @maxX AND ItemY >= @minY AND ItemY <= @maxY
)
SELECT
*,
(SELECT Count(*) FROM RowPost) AS [Count]
FROM RowPost
WHERE Row >= @minRow AND Row < @maxRow
Where Items_View is an indexed view, and WITH(NOEXPAND) is being used to force it to use the indexed view (this is optimal). The line beginning "SELECT Count(*)" is to get the total number of results (without having to run the inner query a second time).
This is running against SQL Server Developer Edition.
SQL Server 2012 :: Query Parses In SSMS But Not In SSIS?
Oct 20, 2015The environment is Server 2008 32-bit, SQL 2012 SP2 Standard 32-bit (11.00.5058), and Visual Studio 10 SP1 (10.0.40219.1).
I have a query that begins with MERGE <tablename> USING (SELECT blah, blah, blah While in SSMS, I can parse the query with no issues. I can execute the query and see the results I expect. But when I put the same query into an Execute SQL Task in SSIS, it won't parse. It gives me one of those very informative messages that I so love - Query failed to parse. Incorrect syntax near the keyword "MERGE".
I don't know if the 32-bit/64-bit thing has any bearing or not, but I have taken the exact same project folder, copied it to a 64-bit box, and it works fine in both SSMS and SSIS. That one is running Server 2012 R2, SQL 2012 SP2 Standard (11.00.5343), and Visual Studio 10 SP1 (10.0.40219.1).
SSMS Truncating Result Text In Select Query
Apr 20, 2015The value of one of the columns in my table is 14000 lines(678913 characters). The datatype of that column is varchar(MAX). I am doing the following select query but its truncating the results.
select value -- this is truncating the text.
from dbo.GUISETTINGS
The length is shown as below when I do the query:
SELECT DATALENGTH(VALUE) from dbo.GUISETTINGS -- return 707951 as the length.
I even tried running the query below but still the value is getting truncated. However, if I right-click and select "Save Results As" a file, then it shows all the lines/characters fine.
select value, cast(value as text), cast(value as varchar(max))
from dbo.GUISETTINGS
How can I get whole column value ?

View 2 Replies View RelatedSp_executesql From App's Dynamic SQL Causing Performance Problems Vs. Query From SSMS
Aug 12, 2006Okay, so I came across an odd performance issue that I'm wondering if some guru can help me out with.
I have a query that uses a paging algorithm that uses a paging algorithm and a table variable, then gets a page of data based on a join to that table variable. Here's a simplified query using the algoritm:
--declare table variable... not shown for brevity
--make sure we only store the least amount of records possible
SET ROWCOUNT ( @pageNumber + 1 ) * @pageSize
--insert into table variable
INSERT INTO @TableVariable( Key )
SELECT key FROM table
WHERE whatever = @p1
--we only want one page of data
SET ROWCOUNT @pageSize
--now get the page of data from the table
SELECT key FROM table
WHERE whatever = @p1
AND [TableVar Identity Column] > @pageNumber * @pageSize
The algorithm works great for our needs, BUT, I noticed something a little odd about its behavior during performance testing.
In particular, when I run the query using Sql Server Management Studio, where I manually DECLARE all the variables it ends up needing only 156 reads to complete the job. When I call it from the app using ADO.NET, however, I noticed it needs 310 reads! Huh?
I looked for differences, and the only one I could determine was that ADO.NET passes the query and uses sp_executesql and passes the parameters vs. declaring and setting them statically before executing the query. I confirmed that this was the issue by manually running sp_execute SQL and seeing that it took roughly the same number of reads (274) to process the query.
Naturally, I don't want the time it takes to perfrom my query to double, but and frankly I don't understand why there would be a difference in performance. Can anyone help me track down what is going on and suggest to me how to fix the problem.
I assume that SQL Server Management Studio optimizes the execution path somehow, but I'm not sure how to gain the same benefit for my passed query. Can I enable something with hints? Is there something else going on that I should know about?

View 2 Replies View RelatedDB Engine :: Cost Vs Time When Including Actual Query Plan In SSMS
Nov 11, 2015I have two queries yielding the same result that I wanted to compare for performance. I did enter both queries in one Mangement Studio query window and execute them as one batch with the actual query plan included.Query 1 took 8.2 seconds to complete and the query plan said that the cost was 21% of the batchQuery 2 took 2.3 seconds to complete and the query plan said that the cost was 79% of the batch.The queries were run on my local development machine. I was the only user. No other programs were running at the time of this test. The results are repeatable.I understand that the query with the lowest cost is not necessarily the fastest query. On the other hand, the difference is quite big. The query that has approx. 80% of the cost takes 20% of the time and the other way around. I have two questions:
Is such a discrepancy normal?Can conclusions be drawn from the cost distribution? For instance, does the query that takes 8.2 seconds but only costs 21% scale better?

View 2 Replies View RelatedHow To Do The Database Transcation Replica ?
Feb 5, 2008Hi,
I am new to SQL server.
I have two databases lets call them A & B, they reside in two PCs, each pC has its own C/C++ program
working with A or B, Two PCs are linked by PPP (for example), but the link is not permonent available,
the link is only available at certain time period, for example, at midnight.and the link is only last
certain period, during this period, A & B will do the transcation replica( just heard about that!) to
make them identical, A=B.
Now are my questions.
(1) Can database use dial up modem itself ? For PC program it is not the problem, but I am not sure whether
MS SQL server database can be configured to do such job automatically ?
(2) Can database have awareness of whether the link is available or not ? For example A is dialing modem, and
B realize that there is a incoming call.
(3) Once link is established, how two databases start to do the transcation replica ? Does SQL server has such ability to do this automatically ?
(4) Can database notice PC program that changes has occured ? so PC program can process it, see display new data.
Thanks

SSIS CDC Components On Asynchronous Secondary Replica
Jan 15, 2015MSDN states the following on: Readable Secondary Replicas (AlwaysOn Availability Groups) for SQL Server 2014:
Limitations and Restrictions:
Change tracking and change data capture are not supported on secondary databases that belong to a readable secondary replica:
Change tracking is explicitly disabled on secondary databases.
Change data capture can be enabled on a secondary database, but this is not supported.
This confuses me: You can not track the changes. However you can enable CDC?
The scenario I am trying to achieve is to use SSIS CDC components on an asynchronous secondary replica. Is this possible? If not what would be other viable approaches?
