Thanks for looking at this for me. Here is the SQL Script as it stands so far.
UPDATE TableImportHistorySET ImportStopTime = CONVERT(numeric, GETDATE(), 108), Elapsetime = CONVERT(numeric,GETDATE(), 108) - CAST((SELECT TOP 1 ImportStartTime FROM TableImportHistory WHERE TableName = 'ARCHRG'ORDER BY DataImportID DESC) AS numeric), Successful = 1WHERE (DataImportID = (SELECT TOP 1 DataImportID AS LastID FROM TableImportHistory WHERE TableName = 'ARCHRG') ORDER BY DataImportID DESC))
The Elapetime update portion of this statement is where I'm getting stuck (if I take it out the statement works)
I get the error "ERROR converting Data type NVARCHAR to Numeric" I've changed the data type in the Table from numric to varchar, nvarchar, decemial nothing works and not sure what I should set the Starttime and StopTime datatypes in the table to (any suggestions please)
Elapsetime = CONVERT(numeric,GETDATE(), 108) - CAST((SELECT TOP 1 ImportStartTime FROM TableImportHistory WHERE TableName = 'ARCHRG'ORDER BY DataImportID DESC) AS numeric)
Are there better ways to do this statement?
Thank you in advance

Hi,
I posted last year when we were having problems with a new SQL box we had moved to here...
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=74650
...we coded round most of the issues and deadlocks and things seemed to improve for quite a while but we have recently run into performance problems again of late.
The CPUs on our SQL box often thrash away at 100% and our ColdFusion website has begun running painfully slow.
Our developers/hosts have suggested we might need to look for a 3rd party SQL guru who could look at the SQL box, do some tracing etc. and perhaps make some recomendations around optimising the DB architecture or changing the way we run certain queries. At the moment we have only gut instinct on which bits of the DB are likely to be being hit most hard.
Our website has grown from being very small to being really quite busy and it's possible we are running into shortcomings with the design of the DB that need to be tackled before we can expand further.
I'm not sure what the protocol is (I see there is a Jobs part of the site) but I wondered about the possibility of getting one of you guys in for a short while to review our server and database, for a fee of course. I'm not sure how long it would take to review that kind of data and get a feel for the usage?
We are based in the UK and whilst I guess it could be done remotely it might be easiest if the person was UK based too.
I'm as much interested in feedback about the idea (it might be not workable/a good idea for example) as I am to people offering their services.
If this post breaks any rules please let me know.
Cheers,
Tem

Don't know if this is the appropriate forum. I am looking for an experienced SS consultant to review our setup, hardware architecture, recovery plan, and to provide high-level advice moving forward. My company is a CRM hosted software provider with a dynamic, metadata-based product built in Visual Studio 2005. Currently we run on SS 2000, but plan to migrate to SS 2005 or 2008. We anticipate quite a bit of growth and want to make sure that we are on the right path. Let me know if you are interested or know someone who is.
If I should post this elsewhere, let me know.

First of all, this is my initial thread here on dbforums. I come from the land of Broadband Reports and would like to say, Hello fellow DB enthusiasts. :)
I'm not a novice to relational databases (Access MDBs), but new to implementing a db via SQL SERVER (2000 in this case) and using Access Data Projects.
My partial db schema is as follows:
participants
---DID (pk) char(1)
---LID (fk - schools) char(4)
---studentLast varchar(50)
---studentFirst varchar(25)
Sample Data would be
010191M001 | 5671 | SPARKS | JONATHAN
030495F283 | 5671 | DYLAN | CYNTHIA
=====================================
enrollhist (insert/update trigger for enrollactive)
---EID (pk - autonumber) bigint(8)
---EMID (fk - enrollmode) int(4)
---DID (fk - participants) char(10)
---LID (fk - schools) char(4)
---enrollactive bit(1)
Sample Data would be
38173 | 4 | 030495F283 | 9003 | 0
38266 | 3 | 010191M001 | 5671 | 0
39022 | 6 | 030495F283 | 9003 | 0
39036 | 5 | 030495F283 | 9003 | 0
39044 | 4 | 030495F283 | 5671 | 1
39117 | 4 | 010191M001 | 5671 | 1
=====================================
enrollmode
---EMID (pk) int(4)
---mode varchar(25)
Sample Data would be
1 | RECEIVED
2 | WAITING
3 | PENDING
4 | ENROLLED
5 | DROPPED
6 | TRANSFERRED
10 | ORPHANED
11 | DENIED
=====================================
schools
---LID (pk) varchar(4)
---CTID (fk - caltracks) char(1)
---AID (fk - agencies) char(1)
---SDID (fk - schooldist) char(1)
---COID (fk - countydist) char(1)
---sitename varchar(25)
---sitetitle varchar(75)
Sample Data would be
5671 | 3 | 2 | 1 | 4 | ASCOT | ASCOT AVENUE
9003 | 2 | 1 | 4 | 1 | ROWAN | ROWAN AVENUE
2865 | 1 | 3 | 2 | 3 | BRIGHT | BIRDELEE BRIGHT
=====================================
caltracks
---CTID (pk) char(1)
---legend char(4)
---trktitle varchar(15)
---trkcnt int(4)
Sample Data would be
1 | 9030 | 90/30 | 4
2 | CON6 | CONCEPT-6 | 3
3 | SNGL | SINGLE TRACK | 1
=====================================
agencies
---AID (pk) char(1)
---legend varchar(4)
---agencytitle varvhar(50)
Sample Data would be
1 | CRYS | CRYSTAL STAIRS
2 | MAOF | MEXICAN AMERICAN FOUNDATION
3 | PATH | PATHWAYS
4 | CCRC | CHILD CARE RESOURCE CENTER
5 | CHSC | CHILDREN'S HOME SOCIETY OF CALIFORNIA
==========================================
THE REMAINING "FKs" FROM SCHOOL ARE SIMILAR, as is other tables and their relationships. The design of the foreign keys were made using sql and the keyword "REFERENCES" and "FOREIGN KEY."
My questions are: :confused:
(1) Is the use of FK as a Constraint any different than using an INDEX and how?
(2) Should I Alter the Tables to include CASCADING Up/Down?
(3) Are the use of CHARs Ok for the Keys?
(4) Have I over/under-normalized any of the relationships?

Hello,
I've proposed to the head of IT at my organisation to head an database development export group to:
- Provide assistance in improving the performance of existing relational databases
- Provide assistance for the development of new database, e.g. correct construction of indexes; data contention, etc.
- Creation of database development standards
- Enforce the above standards for new databases so that the database is not deployed to production servers until it passes the standards.
I'd really like this to be a success as it should improve our rather crappy databases, basically because the people currently creating the databases don't know much about relational design.
Can anyone please post their experiences of setting something like this up, or working on such an expert group where they work? I'd really like to hear the good and bad experiences and what and (what not) to avoid.
Thanks

I have an automation project to review the software. The software is using MSVS2012 and uses DBs from MSSQL2012. Is it possible to restore the DB files on my local laptop to review the code completed thus far? If so what other software would I need besides MSQLserver 2012 on my local laptop.  I'm able to use MSSQL server 2012 on my local laptop, but the DBs are on servers.Â

Here is a script I wrote that analyzes datasets and returns all the minimal composite and unary keys that uniquely identify records. I wrote it because I frequently have to analyze client spreadsheets and non-normalized data tables.
On my desktop server it took about two minutes to analyze 2000 permutations of a table with 50 columns and 5000 records.
Please try it out for me and let me know if it chokes on anything, or if you see any ways it could be improved!

Hi,
I'm having 2 issues on my first "real" SSRS report.
1. How to do a print preview via the preview tab. For print rendering, I have no print preview button on the preview toolbar. Is this normal? MS documention said that there is a Print Preview button. (BOL May 2007 - Designing & Creating reports -> working with report designer -> debugging and Publishing reports (Print Preview)) This report will always be rendered via the printer and it is a "pain" to have to always print it to see changes. The print layout option comes up all black with nothing viewable.
2. How do I reset page numbers back to 1 for report groups? I see no option for this. My report group requires a new page and I want page numbering to start at 1 when the grouping changes.
Note: I'm running VS2005 via Vista (with VS2005 Vista fix installed). SQL2005 SP2 also installed.
Any advice on this will be appreciated. I've spent too much time already where this should be obvious.

Not seeing the Review Data Type Mapping Screen in SQL Server Import and Export Wizard?
Is there only a certain version where that screen shows up?
I am trying to import data from an MS Access application to SQL Server and all of the connections are good, but some of the data isn't and if I let it migrate using this tool it crashes on the bad data and there is no data that migrates. The Review Data Type Mapping screen will allow me to bypass the records in error and load the rest. however, I can;t do that if I cannot see the screen.

Hi all,
my collegue is leaving, his masters in computer science has ensured he has solved most problems we've encountered iver two years...
now im told i need at least a few training sessions under my belt to take over parts of his job.
Basically i need sql server traing and vb but am confused as where to start, a lot of the courses ive looked at assume you have knowledge in certain areas, my problem is i have loads of gaps as ive learnt on the job so need some recommendations- are any of the MS courses geared to people like me or do you need a foundation in the subject....ive read stuff like SAMS teachyourself SQL and found it just doesn't go deep enough....too many examples are just skimmed over....it also doesn't teach you the kind of things i learn here....
im happy to go on a course which repeats stuff i already know whilst teaching me the fundamentals but can only seem to find course geared to specific job roles which require prior knowledge- so where did you guys start? im in the UK btw

I am new to the SQL enviroment and I am looking for a good course to learn more. I have been in the computer industry for a long time but not exposed to this program. I am looking for some training videos/online/books in order to learn more not just to pass a test for certification. I thought I would check some forums and see if anyone could offer up any suggestions of companies/authors for a person that has computer knowledge but knows nothing about SQL.
Thanks in advance for any suggestions.

Hi there,
I'll be going through a training couse for SQL Server next month. The class I'm signed up for is M2780: Maintaining a Microsoft® SQL Server™ 2005. My company uses SQL Server 2000 now and unless I give good reasons to upgrade to 2005, we won't be upgrading. I have very little DBA experience, but since I was told SQL Server is my responsibility, I figured it would make sense to go through some type of training for it. My questions are: Is there enough the same between the two that it makes sense for me to take this class? Are there good business reasons I can give for upgrading? If we don't upgrade is it worth taking a class for 2000 vs 2005?
Thanks for any input.

I think my employer will pay for some SQL training because I have a lot to learn and our needs are fairly involved.
It's my intention to learn and become MCTS in SQL Server 2005 and SQL Server 2005 Business Intelligence.
Where will we get the best bang for the buck for training in these areas?

I'm a solid SQL developer/dba and have some funds earmarked for training this year. I'd like to expand my dba skills...more specifically, I'd like to become a rock-solid enterprise level dba that has not only a solid foundation of skills but some innovative techniques for managing our corporate SQL servers.
I'm curious if anybody has recommendations on training or conferences that might help me dig into those skillsets for a couple of days.
Thanks for your insight.

We have a user Training database that we would like to keep updated from our Production database. Users would make different modifications to the Training and Production databases. It is the user updates on the secondary that bother me and I have not seen anything that indicates Log Shipping would fail if new random records are added to both the secondary and primary.
Would Log Shipping be appropriate for this nightly update of Training from Production?
Thanks
