Can someone tell me how I can write a stored procedure that will automatically increment the value of the index by 001? I am attempting to build a table for a menu system and I need to increment the index value of the document by 001 when submitted to the database. I also need to have the script obtain the last index value of the node before inserting new value.
All ideas appreciated.
Sincerely,
Tim
If interested, this requested is based upon an article written by Michael Feranda:

Choose an EEO-1 Classification: Increase all employees salaries that have: the selected EEO-1 classification by 10%.
Increase all employees salaries by 5% Hi! I am new to SQL, but trying to teach myself. I have had lots of help from you guys and appreciate it very much. Today, I was trying to do the following:
In my table of "Employees", I have a column called classifications. I want to increase the salaries of the employees with a classification of EE0-1 by 10%, but I have not figured out to do so.
My second question is how would I increase all employees' salaries by 5%?
Hello all, I have, what i think, is a unique problem that i'm hoping some of you can help me on.
I need to create a record number that is incremented by 1 whenever someone adds a new record to the database. For example, records numbering 1,2,3 are in the database. When the users adds a new record, SQL takes the last recordno, 3 in this case, and adds 1 to it thus producing 4.
Also, i need to have the ability to replace deleted record numbers with new ones. Using the example above, say a user deletes record number 2. Whenever someone adds a new record, sql would see the missing number and assign the new record that number.
I hope i'm making sense here. Does anyone have any ideas about this? Any articles on the web that someone could point me to?
We are getting the following error on an SSIS package: "54 Diagnostic VirtualSQLName DomainUserName Load Daily 859CF005-CB7F-47D8-8432-AE7C074B343C 1A986F18-343F-4424-ABAB-AC6575187DF3 2007-02-14 10:05:42.000 2007-02-14 10:05:42.000 0 0x Based on the system configuration, the maximum concurrent executables are set to 4. "
Basically it is saying the we have reached the maximum amount of executables. How can we increase this value and where?
I am really starting to like CTEs. My only qualm is that you can only use them within the first statement after you declare them. I wish they would remain active for the duration of the sql batch just like everything else (variables,local temp tables, ect). Is there any trick so that you can use them multiple times? Maybe define them as a string and do dynamic sql or something like that? Hopefully (i have not researched the new version of sql server) in SQL Server 2008 the scope has increase. Anyways any help would be appreciated.
Hi, I created a view on two huge tables. I tried to run a simple SELECT statement on this view and it took me several hours to obtain the result. How can I improve the performance of a view? The view should make use of the indexes built in both table, am I right? Thanks.
"Cursor provide row-by-row level processing and it will store the result sets in 'TEMPDB' database".
(Because of this) or (By using Cursor in Triggers or Stored Procedures) the performance will increase or performance will come down?. I am thankful if I get a good reason for this?
I am receiving an error from my ODBC driver “Maximum number of DBPROCESSes already allocated.”
I confirmed that there are 25 connections and that this is the default. This is caused by error message 10029, SQLEDBPS, when the maximum number of simultaneously open DBPROCESS structures exceeds the current setting. I would like to increase this maximum.
I have found only two ways to do this. One is using dbsetmaxprocs using C and the other is using SqlSetMaxProcs using Visual Basic. My problem is that I am interfacing to SQL Server using a third party tool that is doing the lower level programming.
Is there some way that I can increase the maximum number of DB processes for all databases that are part of the SQL Server 7 environment, or can I set this value using a program that is called from a stored procedure?
Any ideas in this area will be greatly appreciated.
Hi all, I encountered error 1105 (Can`t allocate space for object .....) while running a query. I had dump transaction with no log sucessfully and retry running my query but still encounter error 1105.
I had checked my database size and following are the info: Datasize : 2500MB Database size available : 753.39 Log space : 500MB Log space available : 500MB (this was acheive after after dump trans. twice. it was around 480MB before)
Thus looks like the data segment is full!!! I expanded the size of the disk device D on which the segment device A is on by 50MB. When I did a sp_helpdevice D, the expansion is reflected. Next I run sp_extendsegement, A, D. However running sp_helpsegment A doesn`t show that segment A is expanded. Please help!!! How do I expand the size of the segment? (without creating a new disk device, is it possible) Any other way to resolve this problem?
Also how to check if a particular segment is full? eg. the %usage of data/log segment.
I seem to remember that the font size and type can be controlled in SQL Server 6.5 and the process controlls the fonts displayed throughout the program - Enterprise Manager, Query Tool, etc.
I have just re-installed 6.5 and the fonts are way too small.
We are using SQL server 7.0, our users use to connect to SQL server remotely using Visual Basic Application. When all the users are connected it keeps on increasing the memory utilization and at 1,836,848 KB memory utilization it stops increasing the memory i.e memory utilization become stangnet. The actual amount of physical Memory is around 5GB but SQL server dont increase it after the treshhold level and the performance of the server get affected badly. Any one please suggest me the possible solution.
Am using Windows Server 2008R2,In this Server C:/ drive space is getting increase day by day as per my knowledge i have to format that system.If is there any other chances to get space and remove unwanted things from my Server.
I am trying to increase the price of an product by a user entered % for items with Dishwasher in the itemdesc.
Below is the procedure I have which doesn't appear to show any errors in the SQL Developer.
CREATE OR REPLACE PROCEDURE AdjustPrice( pItemDesc IN ITEM.ItemDesc%TYPE, pPercent IN NUMBER) IS BEGIN UPDATE Item SET ItemPrice = ItemPrice + ItemPrice * pPercent / 100 WHERE ItemDesc = pItemDesc; END;
This is my run script:
BEGIN AdjustPrice ('%Dishwasher%',10); END;
I think the problem is with the way I have done the run script to filter to items with Dishwasher in the description. I tried LIKE an that didn't work either.
I use Sql server 2000.I have implemented paging as guide in link : http://dotnetjunkies.com/Tutorial/975BE770-E5DC-4610-870B-A82BDB9B8845.dcik Is peformance good ? My database has 200000 records. I feel my web application quite slowly in loading. I suppose that 100 user simultaneously run in store above links.Mean that it create 100 temp table and load 100 * 200000 records.is it correct ? Please give me valueable suggestion about performance. Thank you very much.
I'll just throw my question: how could I increase SSIS-performance?
I have a really heavy job with thousands of records my base selection, then I perform some lookups (I replaced most of them by sql) and derived columns (again, I replaced as much as possible by sql). Finally, after a slowly changing dimension task, I do update/insert on a given table. Is there a trick to speed up lookups and inserts (something like manipulating the buffer sizes - just asking). Fact is that I replaced a script task by pure sql-joins and gained 6 of the 12 hours this job took.
i've a db running sql server express sp2. the db size now is 1.1 gb i've a table with a varchar column of size 20 . when i try to increase the column size to 50 i get a timeout exception, and the the cloumn size is unchanged. this table has 2.5 million records
i use sql server management studio express to do the changes
is there a way to increase this timeout or whtever i can do to update this column size?
How can I increase the transaction log size of my sql server 2005 database? i can execute the shrink and backup log which can shrink the .ldf file to 1MB. However, since my dts involves a lot of inserts and updates, the my transaction log grows to 700MB in the middle of my dts execution. How can i increase the transaction log size maximum capacity to probably 1.5GB just so it can accommodate my full dts execution?
I am writing an ASP based application that creates a dynamic querry and then executes it and displays results. I was thinking about writing a stored procedure to increase performance. How much can the SP help me boost querry responce time ???
Well good morning/afternoon to everyone. It's been a while sinse I've posted here and it seems that the site is a lot faster now. Good to see. :) Anyways, I'm working a current problem here at work with our database being quite slow. I've done some research already and will continue to do so but i wanted to get some of your opinions. Right now, I've run the 'DBCC SHOWCONTIG' command and it is telling the following in the first 3 system tables: DBCC SHOWCONTIG scanning 'sysobjects' table... Table: 'sysobjects' (1); index ID: 1, database ID: 6 TABLE level scan performed. - Pages Scanned................................: 34 - Extents Scanned..............................: 12 - Extent Switches..............................: 33 - Avg.

Bytes Free per Page.....................: 6712.0 - Avg. Page Density (full).....................: 17.07% According to the DBCC SHOWCONTIG command documentation, there should be no fragmentation at all. Some questions: 1. would system performance be severly negatively reduced with the above fragmentation (logical and extent)? 2. can the 'DBCC INDEXDEFRAG(dbname, tablename, indexname)' command be issued against those system tables without consequences? 3. is there some other command that can defrag the entire database without having to specify which tables? Also, I have also used the index tuning wizard after a profile trace but that failed with some unknown error. Thats it for now, please let me know if you have some info I could use to help speed up my database.
I am trying to test the connection pooling of my app and need to artificially increase the execution of a stored procedure to 10-15 seconds. There aren't any big tables in my sample data to select on. What would be the easiest way to make a stored procedure fun for a few seconds?
