Oct 7, 2015One of my current responsibilities is to export data to 3rd party vendors. Each export can contain many csv files. The exports are all different in terms of what data is being sent.
The way I have it currently setup is each file that needs to be created is a view. An SSIS package gets the data from the view, writes to CSV, and then sftp to 3rd party vendor. This seemed like a good idea at first because the columns are static but the calculations might change. So all I have to do is ALTER VIEW and I don't have to change anything in the package.
Is there a better way of doing this? I was curious to see what other people are doing. What makes it challenging is that all the exports are so different. If they were similar I could have created generic views that cover all the exports instead of each export having its own view. Eventually I'm going to have 100's of views.
Got An Expensive Server, SQL Is Very Slow On Writes
Feb 2, 2004Hi,
i am experiencing SQl write performance problems on a very shiny server. Got data files on a Raid 1+0, log files on a separate drive, all SCSI, Win2003 server, 6G RAM, 2 Xeon processors. I've created a small benchmarking program and run it on my desktop pc and this 'big' server. Here are the results:
Desktop: SQL server inserts: 78 Seconds, Direct writes to the harddisk(Just write a string to the file 10000 times): 13 seconds
SQLServer: SQL server inserts: 422 Seconds, Direct writes to the harddisk: 16 seconds
So, for some reason, my 'shiny' machine is 6 times slower on writes than my desktop. When i tried comparing the select performance, my shiny server is 10 times faster than my desktop.
Initially i had Raid5 on my server and it had poorer direct write performance but now, direct writes seem to be ok, so, i recon this is a problem related to SQL server.
What can i do to improve the insert performance?
Thanks in advance
SQL Server 2008 :: Queries To Simulate INTERSECT And EXCEPT But With Records In Same Table
Jun 4, 2015Here's the scenario. I have a table (let's call it MyTable) that consists of four fields: Id, Source, FirstField, and SecondField, where Source only takes one of two values: Source1 and Source2.
The records in this table look as follows:
I need to return, using 3 different T-SQL queries:
1) Products that exist only in Source2 (in red above)
2) Products that exist only in Source1 (in green above)
3) Products that exist both in Source1 and Source2 (in black above)
For 1) so far I've been doing something along the lines of
SELECT * FROM MyTable WHERE Source=Source1 AND FirstField NOT IN (SELECT DISTINCT(FirstField) FROM MyTable WHERE Source=Source2)
Not being a T-SQL expert myself, I'm wondering if this is the right or more efficient way to go. I have read about INTERSECT and EXCEPT, but I am a little unclear if they could be applied in this case out of the box.
SQL Server 2008 :: Select Queries With Join Sometimes Fail On Some Remote PCs
Jul 22, 2015I have an intermittent issue where some remote PC's occasionally fail to execute select queries that have a join or return multiple result sets, however simple one table select queries continue to work okay. When it does happen the PC's needs to be rebooted to get to work again. This may only happen some PC's while others continue to work away okay.
I am using a VB6 application and ADO to connect to the database and the error message I get is a General Network Error, Server Not Found when it fails to execute the query. I have ran SQL Profiler on the server and while simple select queries continue to run away okay, a query a join does not even seem to show up in the profiler. The program has been working fine for 15 years with 1000's of users and has only now become an issue on one site for a number of users. Have tried moving the database to a different server and swapping network cards on the local PC's but can't seem to find the cause. The processor and the memory don't seem to be under load, but I am not sure if there is something else in SQL that is causing it to hang under certain conditions.
There have been network analysts experts in to run scans on the network, but I have not had the results of this back yet. Other applications do not seem to be affected so if this analysis does not show up anything.
SQL Server 2012 :: Find Queries That Lock Tables Or Not Using Primary Key While Running Update
Jul 20, 2015I need to search for such SPs in my database in which the queries for update a table contains where clause which uses non primary key while updating rows in table.
If employee table have empId as primary key and an Update query is using empName in where clause to update employee record then such SP should be listed. so there would be hundreds of tables with their primary key and thousands of SPs in a database. How can I find them where the "where" clause is using some other column than its primary key.
If there is any other hint or query to identify such queries that lock tables, I only found the above few queries that are not using primary key in where clause.
SQL Server 2008 :: How To Improve Speed Of Initial Query Vice Subsequent Queries
Apr 23, 2015I have a pretty large DB and a fairly complex query. If I drop buffers and clear cache the query runs in 20 seconds returning 25K rows. Subsequent runs are 2 seconds. Is this the result of the results being cached, execution being cached, other? Are there good ways to close the gap between the initial and later runs? Does the cache stay present until the service restarts or does SQL recycle the memory and if so, based on what criteria?

select d.name, p.*
from sys.databases d join sys.sysprocesses p
on d.database_id = p.dbid

But now we have a new rule that we should not use outdated compatibility views, and one of them is sys.sysprocesses. I checked sys.dm_exec_connections/session/requests but failed to replace my existing code. The first two don't have dbid, the last one, requests, has it, but it selects only currently executing statements.

SQL Server 2008 :: Using Cursors To Find First / Highest And Last Values
Sep 20, 2015I have basic knowledge of T-SQL and I am using Cursors to get the first value, the last value and the peak value and some other values from other tables. I found some examples on google but the code I am using is mixed up. I am using multiple Cursors. I need to join three tables to get the result set into the Cursor. The first example uses 2 tables.
@FirstName NVARCHAR,
@LastName NVARCHAR,
@FirstValue decimal,
@HighestValue decimal,
@LastValue decimal
-- First Cursor
DECLARE TESTCURSOR CURSOR
DYNAMIC
[Code] ....
The above code seems totally inefficient but it gives the correct result. Now I want to pull some more value and join a third table (TABLE z) in the above CURSORS and not sure how to make it working using CURSORS.I would like to use the following in the CURSORS above.
SELECT x.publishdate, y.firstname, y.lastname, y.age, z.initialValue AS FirstValue, z.HighestValue AS Highest, z.LastValue AS Last
FROM TABLE x
LEFT OUTER JOIN TABLE y
ON x.id = y.id
INNER JOIN TABLE z
ON x.id = z.id
SQL Server 2008 :: How To Find Duplicates In A Table As Per Particular Column
Nov 2, 2015I am having a main table and temptable.
Every sunday, new data will be loaded from temptable to main table. I have to make sure that, duplicates does not get loaded from temptable to maintable.
For example, if last sunday a record gets loaded from temp to main. If this sunday also the same record is present then it means that is a duplicate.
The duplicate is decided on below scenario
select 'CodeChanges: ', count(*) from CodeChanges a, CodeChanges_Temp b
where a.AccountNumber = b.AccountNumber and
a.HexaNumber = b.HexaNumber and
a.HexaEffDate = b.HexaEffDate and
a.HexaId = b.HexaId and
[Code] ...
Yesterday (Sunday) , data from temp got loaded onto maintable but with duplicates.
There is a log which just displays number of duplicates.
Yesterday the log displayed 8 duplicates found. I need to find out the 8 duplicates which got loaded yesterday and delete it off from main table.
There is a column in both tables which is 'creation date and time'. Every Sunday when the load happens this column will have that day's date .
Now i need to find out what are all the duplicates which got loaded on this sunday.
The total rows in temp table is : 363
No of duplicates present is : 8
I used below query to find out the duplicates but it is returning all the 363 rows from the maintable instead of the 8 duplicates.
Select 'CodeChanges: ', * from CodeChanges a where
exists
( Select 1 from CodeChanges_Temp b where
a.HexaNumber = b.HexaNumber and
a.HexaEffDate = b.HexaEffDate and
[Code] ...
Need finding the duplicate records which has creation date time as '2015-11-01 00:00:00.000' and all the above columns mentioned in the query matches.
Example
Few colums only metioned below
creationdateandtime HexaNumber HexaCode
1. 1987-10-01 00:00:00.000 5 3
2. 2015-11-01 00:00:00.000 5 3
So here the second record is duplicate. This is what I am trying to find.

SQL Server 2008 :: Find Locations With MAX Sales Amount Per Customer
Feb 13, 2015I have an invoice table with customer, date, sales location, and invoice total. I want to total the invoices by location by customer and see what location sells the most to each customer. My table looks like this.
CustDate LocAmt
A1/1/2014 1520
A1/1/2014 1560
A1/1/2014 2575
A1/1/2014 3580
B1/30/2014 15100
B1/30/2014 15200
B1/30/2014 2575
B1/30/2014 25150
B1/30/2014 35250
I want to get this, because for customer A, location 35 had the largest SUM of sales and for customer B, location 15 had the largest SUM.
CustLoc
A35
B15
If I have to use CTEs to get there, I can do that too. Just a little lost on how to get only the one location per customer.

Nov 2, 2015We have a process that uses a stored procedure: sp_MysteryProcedure....
The problem I am having is: I am 95% certain the issue lies with this stored procedure, but I cannot find the process that calls this procedure. It could be a SQL Server Job that calls the procedure directly, it could be an SSIS (*.dtsx) process that calls this procedure, or some other random process.
One of the big issues is we have tons of *.dtsx packages that call a bunch of stored procedures, but it doesn't seem a normal Windows Search (Start --> Search) searches these files (or perhaps something else is going on with this search).
So my question is multi-part.....
1). How would one go about finding a rouge process that loads data via a stored procedure if we believe we know the stored procedures name?
2). How do you search *.dtsx files?
