MSSQL7 Performance
Jul 16, 1999
I have a SQL Server 7.0 installed on a Compaq PC running on Windows NT. This PC has 64 MB of RAM and it is a Pentium 166. There are 3 Clients connected to it. If there is only one PC running an apllication requesting data from the server, the performance is tolerable, but when there is more than one PC simultenously requesting data from the server, problems araise. Either all of the PCS running the application show zero records on the apllication or one of them show no records. Any mouse click action on the clients will bring the server to almost a halt. Can anyone tell me the reason to these problems?

Hi all,
I hv very little experience handling mssql7. Recently I was assigned a task to maintain a website that uses mssql 7. My system admin has already installed mssql7 server components on a Win2K box and I have only managed to install mssql7 client components on my winXP box.
Whenever I try to connect to the remote server using enterprise manager, I always encounter the same error message complaining that
Quote:
A connection could not be established to "Server Name" - Access denied
ConnectionOpen (CreateFile())..
Please Verify SQL Server is running and check you SQL Server registration properties (by right clicking on the GAMMA
node) and try again.
I have used the client network utility in my winxp box to set up an alias for the server using various network libraries such as TCP/IP and named pipe, but it keeps on returning the same access denial message.
I am running out of brain juice figuring about what's wrong. Could somebody please help me? Thanks in advanced.

While installing SQL 7.0 it turned out that the size of my primary patrtition where the Windows NT system files are {C: drive) does not have enough space to take the MSSQL7 system files it wanted to install there. Can the size of this partition be increased (am using FAT file system), can the MSSQL7 system files be installed somewhere else, or should I just do an f disk and start all over again with a new Windows NT installation? (No data on this server yet.) Thanks for your help!

We've experienced a problem with one of our MSSQL7 servers where transactions are not being committed to the database. We've experienced this in Query Analyzer -- where we run several (simple) insert or update statements. Although the script runs successfully, the rows do not appear in the tables. The implicit transaction setting is off for the server.
We have also experienced this problem with other tools that run against this server via ODBC.
I thought the default setting for MSSQL7 is to auto-commit transactions and I've seen nothing in the error log that indicates that the updates were rolled back. I have compared our server, database and client configuration options to other servers that do not have this problem and have no idea where to look next.
Has anyone encountered this problem? Or does anyone have some ideas about where I could look for more information?
Thanks!

Hi,
I am trying to figure out a way to link a MySQL database (running on Linux) to my MSSQL7 database. My ultimate goal is to synchronize inserted/updated/deleted data in the MSSQL7 DB to the MySQL DB.
I have tried a few things and have had a few ideas. They are:
1) Create table triggers in the MSSQL7 DB that will synchronize the data to the MySQL DB. I can't figure out how to run Transact/SQL statements (INSERT, UPDATE, DELETE, etc.) into an ODBC DSN pointing to the MySQL DB. I think this could be done with a linked server (see next item).
2) Add a linked server under Security->Linked Servers in the MSSQL7 Enterprise Manager. I have managed to get the remote MySQL server to link in here. I can even see the table names in the server browser, so that's encouraging! However, I cannot figure out the syntax of the fully-qualified table names in my SELECT statements. I have tried this:
SELECT * from LinuxBox..MyDB.MyTable
-and-
SELECT * from LinuxBox.MyDB.MyDB.MyTable
but I get:
Server: Msg 7312, Level 16, State 1, Line 1
Invalid use of schema and/or catalog for OLE DB provider 'MSDASQL'. A four-part name was supplied, but the provider does not expose the necessary interfaces to use a catalog and/or schema.
This statement:
SELECT * from LinuxBox...MyTable;
gives me:
Server: Msg 7313, Level 16, State 1, Line 1
Invalid schema or catalog specified for provider 'MSDASQL'.
Since I can see the table names in the linked server browser in Enterprise Manager, though, some kind of connection must be active. I just need to figure out how to refer to the remote tables.
A big problem is that when I supply a catalog name while defining the linked server, I get an error message from the Enterprise Manager:
Error 7399: OLE DB provider 'MSDASQL' reported an error. The provider reported an unexpected catastrophic failure.
Therefore, I can't define a catalog with the linked server. I think a catalog is required for the "4-part name" to work in the SELECT statement above.
3) Write an extended stored procedure that uses the ODBC function library to make a connection to the MySQL DSN and have a table trigger call the ESP. Hoping to be able to do something simpler than this!
Any suggestions would be greatly appreciated!
Thanks,
Greg

Dear All,
could you please tell me if MSSQL7 is compliant with Windows 2000 ?
Which Service Pack is needed from both MSSQL and W2000 ?

I'm trying to bcp logins from 6.5 to 7.0 while maintaining the passwords. I tried doing a bcp in native format, but when I try to bcp in, I get a Dr. Watson. I figured out the issues with syslogins not be updatable on 7.0 because its a view. I'm also aware of the problems associated with the fact that sysxlogins on 7.0 has different column definitions than syslogins on 6.5. I just don't know how to get around these roadblocks. Anyone have any ideas??
Thanks in advance,

I was using MSSQL7 for a long period.
I upsized to MSSQL7 from Access some years ago. Without any particular reason when writing code in stored procedures, when I wanred to select some records having a bit column to true I used the syntax bitcolumn=-1 (and not bitcolumn=1). This behavior was used in Access. Everything worked fine. Then I moved to MSSQL2000 and by restoring the MSSQL7 database I had no problem.
However, in order to use some features of MSSQL2000 I had to run the sp
sp_dbcmptlevel <database>, 80
After that the condition bitcolumn=-1 didn't work.
Can anyone verify this behavior, since I have to make dozens of changes in my stored procedures and triggers???
Regards,
Manolis Perrakis

Hi there,
Does anyone know if it's possible to perform a MSSQL7 database backup on a network drive instead of the local drives ?
...and if yes, how to proceed ?
It seems to be possible under MSSQL2000.
Many thanks for your help in advance,
Matt

I have a table in mssql7 that has 7000000 record and I want to take100000 records out of it and place them into the new machine withmssql2000. The new machine will also have the same table name, so Iwant to append the 100000 records into that table.Thanks,Royal344--Direct access to this group with http://web2news.comhttp://web2news.com/?comp.databases.ms-sqlserver

Sorry about the huge post, but I think this is the amount ofinformation necessary for someone to help me with a good answer.I'm writing a statistical analysis program in ASP.net and MSSQL7 thatanalyzes data that I've collected from my business's webpage and thehits it's collecting from the various pay-per-click (PPC) engines.I've arrived at problems writing a SQL call to generate certainstatistics.Whenever someone enters our site from one of the PPC search engines, Iwrite out a row to the Hits table. In that table are the followingcolumns:HitID - the Unique ID assigned to each hit that comes into the siteKeyword - the keyword the user searched on when he or she came to thesiteSearchEngine - the PPC engine the user came fromSource - this is pretty much always 'PPC'...if we were to do otherthings, like a newsletter, then this would be different.TimeArrived - the date and time the user arrived at the website. Ihave no idea why I didn't call it "datearrived," since I use "date"and not "time" pretty much everywhere else...(I don't think the rest are important, but they might be, so I'llinclude them for completeness's sake)Referring URL - the URL the user came fromReferring Website - the string between the 'http://' and the first '/'in the URL. I know it's redundant information, but when I designedthis part, I didn't know how to parse it out afterwards, so I justfigured I'd duplicate it.Page Visited - the page the user first arrived atWhen a person comes to the site, I also write out a session cookiecontaining the user's hitID. If the person fills out an enrollmentform (a process which we refer to as "responding"), I attach thatsession ID to the form. The response form (and thus the responsestable) is long; these are the important fields:id - a unique ID for each responsedate - the date and time of the responsestatus - a varchar field containing a status code. I would have madeit a number, but I wanted it to be viewable from looking at the rawdatabase.hitid - the HitID of the user, taken from the session cookie. If thereis no session cookie (for whatever reason), the HidID is written outas 0. While it wouldn't occur often, I can't guarantee that there willnever be more than one response record attached to a singular hitid.Later, some of the responses turn into "confirmations", which meansthat they've actually ordered from us, not just filled out the form.This usually happens about three or four days after the initialresponse. When this happens, the status of the response is changed toa phrase containing the word "confirm" in it (there are a few of them,but they all contain that word).So now that we've collected all this marketing intel., I need toanalyze it.I've written a parser that takes reports from various pay-per-clickcompanies and puts them into a table called PPC. Information in thiscolumn is written out as one record per search engine per keyword perday. The schema is as follows:id - a unique ID for the record in the tabledate - the date to which the information in the record appliessearchengine - the PPC engine to which the information applieskeyword - the keyword to which the information appliesclicks - the number of clicks on the applicable keyword on theapplicable search engine on the applicable day.impressions - same as clicks, but for impressionscpc - the cost per click on the applicable keyword ...avgpos - (I don't always have a value for this field) The averageposition that the keyword was shown in for the applicable keyword ...With this data in, the last step is actually analyzing the threetables for useful statistics on the various keywords, search engines,and time frames. That's the step I've been trying to complete.So what I need is a SQL call that I can run that generates a tablewith the following information:SearchEngineKeywordCost / Click - When calculating the CPC, I can't just take an averageof all the records. I need to calculate the total amount spent per day(clicks * cpc), add that up for every day, and then divide that by thenumber of total clicks. Just doing an average doesn't take intoaccount the fact that some days we'll get more clicks than others.Total Spent - # Clicks * CPC#Responses - counting the number of records in the responses table#Confirms - counting the number of records in the responses table with"confirm" in their statusTotal Spent / #ResponsesTotal Spent / #ConfirmsOh yeah, and I want to be able to order by any four of the fields inany order, narrow my selection to only those keywords that either areor contain a user-specified string, further narrow my selection toonly those records that fit other user-specified criteria for any ofthe columns in the table I'm generating, and select only the top xrecords (where x is a user-specified number). I already haveuser-controls that output the SQL for all of these things, but I needto have places in which I may put that SQL in my call.After many trials and tribulations, I've come up with the followingSQL call. Right now, its output for nearly every row is incorrect, Ithink in a large part due to the fact that the method that I'm usingto generate the number of clicks is yielding incorrect values.If you'd like to help me and you think that modifying the followingcall is easier than writing a whole new one, be my guest; if you'dprefer to write a new one, I'm game for that, too. I'm just concernedwith its working right now, and any help you can give me is greatlyappreciated.Anyway, here's the call:/*sp_dboption @dbname='NDP', @optname='Select Into', @optvalue=true;*//*Running the above might be necessary to get the "Select Into"s towork*/Drop table ResponsesPPCDrop table ConfirmPPCDrop table TempPPCSELECT Responses.[ID] as [ID], Responses.Status, PPC.SearchEngine,PPC.KeywordInto ResponsesPPCFROM Responses, PPCWHERE Responses.HitID IN(SELECT Hits.HitIDFROM HitsWHERE Hits.SearchEngine = PPC.SearchEngineAND Hits.Keyword = PPC.Keyword)SELECT ID, Status, SearchEngine, KeywordInto ConfirmPPCFROM ResponsesPPCWHERE Status LIKE "%confirm%"Order by SearchEngine, KeywordSELECT PPC.SearchEngine, PPC.Keyword,SUM(PPC.Clicks), /*I noticed that thiscolumn gives me incorrect values(I don't need it in my final report, but it's useful for debugging).For some keywords, it gives me huge numbers(e.g. 265 clicks on one word that got ~10 clicks /day over five days),and for others, it doesn't give me enough. I think this is a majorpartof what's throwing off the rest of the statistics*/Case SUM(PPC.Clicks) WHEN 0 THEN 0 ELSESUM(PPC.clicks * PPC.cpc) / SUM(PPC.Clicks) END as CPC,SUM(PPC.clicks * PPC.cpc) AS TotalCost,count(ResponsesPPC.ID) As NumResponses,Count(ConfirmPPC.ID) As Confirms,(Case Count(ResponsesPPC.ID) WHEN 0 THEN 0 ELSESUM(PPC.clicks * PPC.cpc) / count(ResponsesPPC.ID) END) ASCostPerResponse,(Case Count(ConfirmPPC.ID) WHEN 0 THEN 0 ELSESUM(PPC.clicks * PPC.cpc) / count(ConfirmPPC.ID) END) AsCostPerConfirmFROM (PPC LEFT JOIN ResponsesPPC ON PPC.SearchEngine =ResponsesPPC.SearchEngineAND PPC.Keyword = ResponsesPPC.Keyword)LEFT JOIN ConfirmPPC ON PPC.SearchEngine = ConfirmPPC.SearchEngineAND PPC.Keyword = ConfirmPPC.KeywordGROUP BY PPC.SearchEngine, PPC.KeywordOrder by PPC.keyword desc/*Drop table ResponsesPPCDrop table ConfirmPPCDrop table TempPPC*//*I don't drop them right now so I can look at them,but normally, one would drop those tables.*/Thanks a lot for your help,-Starwiz

Greetings!
I recently rewrote an old ACCESS 97 application to work with MSSQL 7.
The program works fine until I use a form whiche opens several linked tables at the same time. When closing the Form I get (At unpredictable moments) an ODBC SQL SERVER DRIVER update failure error message.
All rights are set on the tables for Public and even then i keep getting this error at very odd moments. I also had a look in Access at the ODBC refresh rate which is set at 10sec , OLEDB refreshrate 10 sec, and refresh is set at 5sec.
I tried different combinations of timeout settings and even renewing the MDAC to version 2.7.
Nothing helps.
Can anyone give me a tip as to look for the possible source of the error and how to fix it?
Thanks!

get my old database from my [Server1]* to my [Server2]*. When Im
trying with the "SQL Server Management Studio" that included in
the MSSQL 2005 but that just tells me it dosn't support any version
before MSSQL2000.. I've also tryed with some third part softwares
like EMS but no joy!... Its 5 databases from the old server that I MUST
get into the new one.. Anyone know howto do this?
[Server1]
Windows 2000
MSSQL7

1. Use mssql server agent service to take the schedule
2. Use a .NET windows service with timers to call SqlClientConnection
above, which way would be faster and get a better performance?

Hello Everyone,I have a very complex performance issue with our production database.Here's the scenario. We have a production webserver server and adevelopment web server. Both are running SQL Server 2000.I encounted various performance issues with the production server with aparticular query. It would take approximately 22 seconds to return 100rows, thats about 0.22 seconds per row. Note: I ran the query in singleuser mode. So I tested the query on the Development server by taking abackup (.dmp) of the database and moving it onto the dev server. I ranthe same query and found that it ran in less than a second.I took a look at the query execution plan and I found that they we'rethe exact same in both cases.Then I took a look at the various index's, and again I found nodifferences in the table indices.If both databases are identical, I'm assumeing that the issue is relatedto some external hardware issue like: disk space, memory etc. Or couldit be OS software related issues, like service packs, SQL Serverconfiguations etc.Here's what I've done to rule out some obvious hardware issues on theprod server:1. Moved all extraneous files to a secondary harddrive to free up spaceon the primary harddrive. There is 55gb's of free space on the disk.2. Applied SQL Server SP4 service packs3. Defragmented the primary harddrive4. Applied all Windows Server 2003 updatesHere is the prod servers system specs:2x Intel Xeon 2.67GHZTotal Physical Memory 2GB, Available Physical Memory 815MBWindows Server 2003 SE /w SP1Here is the dev serers system specs:2x Intel Xeon 2.80GHz2GB DDR2-SDRAMWindows Server 2003 SE /w SP1I'm not sure what else to do, the query performance is an order ofmagnitude difference and I can't explain it. To me its is a hardware oroperating system related issue.Any Ideas would help me greatly!Thanks,Brian T*** Sent via Developersdex http://www.developersdex.com ***

We have the same application installed on a few different environments with similar servers and similar hardward. The only difference is the versions of SQL and the colations.
Is SQL 2005 a lot faster that SQL 2000? Could colation type make a big effect on performance?

What's my best bet in getting better performance out of one of my database servers? Currently we have 1 set of Raid5 disks partitioned into 2 drives. This houses everything (system, database, and logs) If that server has 2 slots left for drives I was thinking of putting 2 mirrored drives and getting the logs off the main database space? (Make sense?) This is a vendored application so working with new indexes etc. isn't something I should do wo/ the vendor's interaction. Will what I describe above help?
Thanks

We have SQL Server running on a dual processor Pentium 500mhz server. Our database is hit by about 300 users. 200 of those users are doing constant searches though a client table of about 250,000 records, which in turn is linked to a history table containing over 5,000,000 records. This is only the tip of the iceberg, we have many triggers, procedures, updates, etc. going in the background. The database has over 500 tables.
Keep in mind, these searches that are taking place can involve all kinds of fields: phone number, company name, fax number, first name, last name, status, wildcard searches, etc. So as you can imagine, the database is being hit with all kinds of funky requests to find records. I will be the first to admit that our developers (vendor) are not the best code writers, and we have a tough time getting them to optimize something they do not even understand themselves.
As I speak, our processor utilization is maxing out between 95 to 100 percent. I've done a lot of performance tuning and all of the problems lie in the searching. We've built, tested, rebuilt, re-tested each and every index. I even used the Profiler to filter what I could. It has improved, but our database is growing at a rate of 10 megs a day (already close to 3 gigs, not that huge). I think I've optimized my indexes as best as I can considering all the fields and possibilities available to users to search for records.
For a database that requires all of these different search criteria, what would be a more optimal server? We are looking to purchase something ASAP. I could really use help from someone in a similar situation. It seems odd, in mind, that a company of 300 people would need to rely on a quad server (four processor capability.).
Thanks. JT

I am running a SQL 7.0 server on a two processor machine. We are having some performance issues.
one of the processor is always above 90% utilization but the second is barely at 50%.
Will adding another processor help or are the processes locked to one processor.
The server is a dedicated sql server. nothing else is running on it.
Thanks for any info you can provide.

We have recently upgraded to SQL 7.0 on NT 4.0/sp6 box which has got 4 PIII 700 processors, 1GB RAM, and 70GB HDD on RAID 1 and RAID 5. We feel that the application performance is not great as expected in SS7. (The application was running in 6.5 smoothly and performance was good)
Is there any option needs to set to improve performance? Now, SS 7 using all the 4 processors and dynamically allocated memory, etc. Any thoughts greatly appreciated.
Thanks in Advance

I'm running MS SQL Server on a 1.4 GHz AMD Athlon Processor with 750 MB or RAM and ample disk space. I have a table with 14 columns; 2 datetime, 8 int and the rest are varchar of various sizes less than 13.
I run a java process on another machine that connects to the database and insert records. It takes about 6 minutes to insert 100,000 records.
I run the xp performance monitor and only about 25% of the SQL Server machine's cpu is being used. I run top on the Linux box running java and I see about the same results. Neither machine is kept busy processing. Why don't I get better performance? Could my local area network be that slow? How many inserts per minutes is good performance?
Thanks for your input.

Does anyone know the performance differences between returning data from SQL Server as XML vs. as a record set? We are about to dive into the For XML world full force, but we wanted to make sure that we are not heading for a performance nightmare.
Thanks for any insight on this. I'll try to look for white papers and do some testing in the meantime.

I ave the following Code in my Stored procedure.
Declare Cursor for table A
WHILE @@FETCH_STATUS = 0
Get values from other function based on some business logic.
INSERT Into another table B
(or)
UPDATE to another table B
END
I have to insert/update values to table B, one by one row. So, it is taking more time.
Is there any way to collect the values into a temporary storage and Insert/update or Move the values to table B.
