SQL 2012 :: CLR Returns Dates In Different Formats On Different Servers
Oct 2, 2014
I've just restored a DB from one server to another. Part of the DB is an assembly used in a Function that unencrypts some data held in a Varbinary(Max) column.
When I execute it on the original server it works fine across all rows of the table, when I execute it against the new server it fails because it's seeing dates in MM/DD/YYYY format, it works if the day of the month is less than 13, but obviously the date would be wrong!
Setting the DATEFORMAT to MDY prior to executing the function has no effect either.
It's the same DLL in the same location, the SQL Server settings as returned by DBCC USEROPTIONS() are identical.
The SQL Server editions and Window OS are the same

I'm thinking the DLL is being affected by some setting either in the Windows OS or a SQL Server setting ...
We have a customer that is running SQL2012 and we are seeing a weird result on a query when we run it on their db. It is based off of a table that has about 30 columns but in this case we only care about 2 of them.
[Number] [varchar](15) NOT NULL [Person_ID] [varchar](12) NULL
Here is the query we are doing: Select Number,Person_ID From TableName where LP='ABC123'
The result I get back is the following: Number:1 Person_ID:13864
The Person_ID should be a result of another table that created that Person_ID but it doesn't exist in that table. So we do not know where that 13864 is coming from. When we open that record through our application it shows Nothing for the Person_ID in that field.
When we do this query on our copy we get back Number:1 Person_ID:
Which is exactly what we should see as the result.
Could there be a sql server setting that is set on their server that could possibly be given us back 13864 for a NULL value?
From what I've seen, the CheckSum_Agg function appears to returns 0 for even number of repeated values. If so, then what is the practical use of this function for implementing an aggregate checksum across a set of values?
For example, the following work as expected; it returns a non-zero checksum across (1) value or across (2) unequal values.
declare @t table ( ID int ); insert into @t ( ID ) values (-7077); select checksum_agg( ID ) from @t; ----------- -7077 declare @t table ( ID int ); insert into @t ( ID ) values (-7077), (-8112); select checksum_agg( ID ) from @t; ----------- 1035
However, the function appears to returns 0 for an even number of repeated values.
declare @t table ( ID int ); insert into @t ( ID ) values (-7077), (-7077); select checksum_agg( ID ) from @t; ----------- 0
It's not specific to -7077, for example:
declare @t table ( ID int ); insert into @t ( ID ) values (-997777), (-997777); select checksum_agg( ID ) from @t; ----------- 0
What's curious is that (3) repeated equal values will return a checksum > 0.
declare @t table ( ID int ); insert into @t ( ID ) values (-997777), (-997777), (-997777); select checksum_agg( ID ) from @t; ----------- -997777
But a set of (4) repeated equal values will return 0 again.
declare @t table ( ID int ); insert into @t ( ID ) values (-997777), (-997777), (-997777), (-997777); select checksum_agg( ID ) from @t; ----------- 0
Finally, a set of (2) uneuqal values repeated twice will return 0 again.
declare @t table ( ID int ); insert into @t ( ID ) values (-997777), (8112), (-997777), (8112); select checksum_agg( ID ) from @t; ----------- 0
comparing UNIQUEIDENTIFIER columns..This query returns several rows where the [ReportId] and [LastRunDate] columns are both NULL:
SELECT [c].[Name],[c].[ItemID],[xl].[ReportID] , MAX([TimeStart]) [LastRunDate] FROM [dbo].[Catalog] [c] LEFT JOIN [dbo].[ExecutionLogStorage] [xl] on [c].[ItemID] = [xl].[ReportID] WHERE [c].[Type] NOT IN (1,5) -- Not a folder or a data source! group by [c].[Name],[c].[ItemID],[xl].[ReportID] order by 4
However, trying to just list catalog reports with no execution history returns 0 rows, but I'm expecting it to return a row for every NULL [ReportId] from the above query:
SELECT * FROM [dbo].[Catalog] WHERE [Type] NOT IN (1,5) -- Not a folder or a data source! AND [ItemID] NOT IN (SELECT [ReportID] FROM [dbo].[ExecutionLogStorage])
I even tried casting [ItemId] and [ReportId] columns in the 2nd query to VARCHAR(255), and still got no rows, but the following queries return 0 rows and 1 row (respectively).
select * from [dbo].[ExecutionLogStorage] where [ReportID] = '0BB2209C-7736-46C8-AD02-4614EBA4F0F1' select * from [dbo].[Catalog] where [ItemID] = '0BB2209C-7736-46C8-AD02-4614EBA4F0F1'
Is there a way to make a single insert (in a loop) and take system dates and insert them in different languages without making a new loop for each language.
I am designing a database to store data from a leak tester.
We want to display the results between dates, I mean, the results of the leaking test are going to be stored as well as the datetime in which they have been performed.
ID (int) RESULT (float) TS (datetime)
The query will be, of course:
SELECT * FROM TABLE Where TS BETWEEN DT1 and DT2
This table is growing by 10000 rows a day, it is possible that in a year getting the values between two dates became impossible.
Using a index with a datetime field sounds like a crazy idea.
SELECT SUM(((CASE WHEN o.date>= a.activity_date, other filter condition, other filter condition THEN (select coalesce(d.balance,d2.balance) from drawtable d where coalesce(d.date, d2.date) < a.activity_date order by d.date desc limit 1) - ( select coalesce(d.balance, d2.balance) from drawtable d where coalesce(d.date, d2.date) = interval 'current date' else end ))
from emailtable a LEFT JOIN opportunity o left join drawtable d left join drawtable d2 etc
The tricky part is I'm joining that same table twice.....would this be better in a max/min case when statement?
I have 2 server PROD n DR server all the PROD server DB is synched to DR server through log shipping. Now to chk whether the DR server is working or not in case of any disaster we shut down the PROD server now all the app request is handled by DR server,it is working fine. For 1 week we work in DR server now its time to move back to PROD server so that all the 1 week data in DR server should be replicate back to PROD server. Log shipping is deleted once the DR Server is up. What r the options other than Backup? It is SQL 2012
I have a dataset that contains an EmployeeID, StartDate, EndDate, and Location. Each record tells me at which location and employee was during a payroll period (fortnightly). So the data looks like:
Employees can be at multiple locations during the two weeks. They can work at one location, stop working there, start working somewhere else, and then maybe go back to their old location. There are duplicate records here as each employee can be at the same location multiple times during the two week period. What I need to capture is the actual start and end date of an employee at each location for each 'assignment'. An assignment is defined as a continual period of employment at a location with gaps of no less than 4 days - if there is a gap of more than four days then that is classed as a new assignment.
The RECORDSTATUS value of 1 means the record is active. A corresponding record of the same CustomerID, Tier. in startdate chronology, with a value of 0 indicates that the previous record with the status of 1 has now terminated and the startdate of the record with recordstatus of 0 is the start date of the termination of the previous record, or better stated, the end date of the previous record.
What I need to do is re-record the above data the startdate of each terminated record become an enddate for the previous record, minus 1 day, as follows:
CUSTOMERID TIER STARTDATE ENDDATE 123 A 01/01/2013 02/28/2013 123 B 03/01/2013 05/31/2013 123 A 08/01/2014 NULL 456 C 02/01/2014 NULL
I have three tables: EMP (ID, NAME), EMPDATE (ID, STARTDATE, ENDDATE), YEAR(YEAR)
I would like to get the most recent date within a given year per each EMP? For example, EMPID 1 can be enrolled in many programs, each program has start end dates. I need to list the most recent date an employee was enrolled (max date between START AND END DATE which ever is most recent enrollment) for a given year. For example, for 2014 his/her most recent enrollment should be 10/23/2014 for year 2014 and 2013-10-24 for year 2013.
SELECT ID, EMP.NAME, DTE.StartDate, DTE.ENDDATE, year FROM EMP_DATE DTE join EMP_INFO EMP on EMP.ID = DTE.ID join YEAR YR on YR.YEAR = YEAR(DTE.STARTDATE)
I would like to know if it is possible to split a database across different servers, in the same manner you can split it over multiple drives on the same server We are trying to balance the load cause we are finding that the current server can't handle the load
I have multiple instances of SQL 2012 Std Edition on a 40 physical core server.What I have done is the use the Process - SQLServr -% Processor time Stat and divided by 16 ( the max number of Cores Std ed. can use) as a instance level measure. I also use processor object stats to show how busy the server is. How to represent the servers CPU utilization?
One of my client asking mirroring between two server with witness.Is it possible witness and mirror in same server(with same instance)? OR Is it possible witness and primary in same server(with same instance) ? Best method to establishing mirroring with in two servers(with witness) ?
I am trying to reproduce a problem that is probably related to how a particular SQL server is configured. Is there a tool or best practice that is useful to compare all of the configuration settings between two SQL Servers (same version)?
I have installed SQL Server on Server A. I have installed Integration Services on Server B.I found that you need to addto the integrations services MsDtsSrvr.ini.xml file the server for the database if you want to use MSDB package store. The issue I have now is how do I execute the jobs on the Integration Server. I dont want them to execute on the SQL Server. Is there a way to configure the SQL Server Agent jobs to execute the package on the other server? Do you have to setup windows scheduled tasks or some other tool to execute command line packages on the IS server?
I'm looking for any info on segregating these roles but still using the MSDB store for pacakages. I don't want SQL server installed on the IS server or IS on the SQL Server. I want the Integration Services server to do all processing... not database level obviously but flat file reads, web service calls, data manipulaiton, custom code, etc and just pass the input/output of data to the SQL server for storage or retrieval to offload the workload and segregreate responsibilities.
Does MSDTC auto-install with the plain vanilla version of SQL Enterprise? Or do I have to install it later?Do you know of any links that reference specifically SQL 2012 stand-alone server installs of MSDTC?
I have a table with a list of jobs along with their start and end datetime values.
I am looking for a function which will return the time taken to process a job using a start date and an end date. If the date range covers a Saturday or Sunday I want the time to ignore the weekends.
Example
Start Date=2014-05-15 12:00:00.000 End Date=2014-05-19 13:00:00.000
Total Time should be: 2 Days, 1 Hour and 0 Minutes
This function will return working hours between given 2 dates. This function assumes that the break is between 9:45 AM and 10 AM and that Lunch is between 12:30 PM and 1 PM. This function also assumes that the working hours are between 7:30 AM and 4 PM. There is a section for public holidays there. We have a table for that you might not so that piece needs to be fixed.

currently need to re-create an aggregate table in a proc every night to aggregate purchases broken down by person/store in groups of 3, 6 12 etc months.finding the performance of it is very slow as it covers 500,000 million rows.The query looks like
SELECTCusID(int) , StoreID(int) , SUM(L3M) as Last3Months , SUM(L6M) as Last6Months , SUM(L9M) as Last9Months
[code]...
I need to make changes to this because it is using a BETWEEN on a datetime column. I was wondering though, if anyone else has made agg tables like this before an found a better way of doing them?
What I need to be able to find is any records where the Discontinue_Date is greater than the Effective_Date on the next row for a given Customer ID and Part_ID. This is a customer pricing table so the Discontinue_Date of row 53 for example should never be greater than the Effective_Date of row 54130, these are the records I'm looking to find. So I'm looking for a SELECT query that would look for any records where this is true. Obviously the last Discontinue_Date row for a Customer_ID will not have a next row so I wouldn't want to return that.
I have a table with appdt as first appointment date and the another record for the same customer# has follow up appointment.
Each customer is uniquely identified by a customer#
I need to find out if the customer came back after 200 days or more when the first appointment date was between jan12014 and Aug 31 2014. I am only interested in first follow up appointment after 30 days or more.
Scenerio : To keep a very large system running optimally in a VM cluster, Take PR01 and make PR02, PR03, PR04. Distribute the 45 databases and 9T+ of disk across multiple VM guest.
Each PR## is a SQL Server 2012 Enterprise guest on a VM 5.1 cluster.
So instead of PR01 needed 16 core and 128g of memory, each one will have 4 core and 32g of memory. Making VM HA more manageable. (yes, DRS rules will apply). Also provides more HBA paths and distributes i/o over more physical disk on the SAN.
Instead of a connection string having to know PR01.dbo.UserDB01, PR02.dbo.UserDB03, ect the connection would be PRDB.dbo.UserDB01. That way if needed 1) UserDB can be moved to any of the PR## 2) new PR05, PR06 can be added as needed. The end user and processes are not allowed to touch system databases, no PR## will have a user DB called the same name.
There are seperate VM guests on other VM clusters and Citrix servers that need access to PRDB. As things expand and move around, none of the connection strings need to be changed.
I am looking into RadWare and modifing level 7 information, but that is iffy and $$$$$$.
I created a maintenance plan with full user database backups, backup files cleanup, and database shrink.
I did it in SSMS and it also created "Reporting Task for subplan-{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}".
It works fine in the development server where I created the plan. I imported the same into other environments test, stage, and prod. I did use BIDS to change the connection string manual "Local server connection". The job runs fine in other environments but it fails at the end where the "Reporting Task for subplan" is executed. I looked at the dtsx file codes and I could not find anything wrong.
Curious what the industry standard is combining multiple instances on single server ?
Right now i have separate servers for OLTP, SSAS, and SSIS, and for OTP have Development, Test, and production environments. Im considering combining the SSIS and SSAS services into additional instances on each environment servers.
Now (Production) OLTP SSAS SSIS
After
1 Server with 3 separate instances for SSAS, SSIS, OLTP. Then replicate this model through the environments to utilize development and testing.
