it runs to completion in about 15 min - during the entire time there is extensive used of CPU from Task Manager.
If I do the above statement, it seems to use lots of resources (50% +) for about 5 min, then falls to 5%. It just seems to sit there, for an hour + at which time I've killed the query.
This is actually the second time I tried this. The first time was on a different machine, with the P4, 3GB RAM, plenty of disk space, and using SQL-Server 2005 Standard - SP1. Exactly the same decrease in resources happened, and even though it ran several hours, no results.
Any thoughts here - not waiting long enough, memory leaks, etc.?
Hi,I have table with three columns as belowtable name:expNo(int) name(char) refno(int)I have data as belowNo name refno1 a2 b3 cI need to update the refno with no values I write a query as belowupdate exp set refno=(select no from exp)when i run the query i got error asSubquery returned more than 1 value. This is not permitted when thesubquery follows =, !=, <, <= , >, >= or when the subquery is used asan expression.I need to update one colum with other column value.What is the correct query for this ?Thanks,Mani
Hello,I have 2 ways of updating data I'm using often1) via a cursor on TABLE1 update fields in TABLE22) via an some of variables ...SELECT @var1=FLD1, @var2=FLD2 FROM TABLE1 WHERE FLD-ID = @inputVARUPDATE TABLE2SET FLDx = @var1, FLDy = @var2WHERE ...Now I have a system with 2 databases and I need to update table DB2.TABbased on data in DB1.TAB. Instead of using 1 of the 2 ways I normally use,I thought it would be much easier to get the required data immediately fromDB1.TAB in the update-statement of DB2.TAB ... but the way to do thatconfuses me. I've checked books online and a lot of newsgrouppostingsgiving good information but still I keep getting errors like this ...The column prefix 'x.ADS' does not match with a table name or alias nameused in the query.while executing the following statement ...UPDATE DB2.dbo.TABSETFLD1 = x.FLD1,FLD2 = x.FLD2,...FROM DB1.dbo.TAB x, DB2.dbo.ADSWHERE DB2.dbo.TAB.REFID = x.IDOFTAB1 AND DB2.dbo.TAB.IDOFTAB2 =@InputParameterSo in DB2.TAB I have a field REFID reffering to the keyfield IDOFTAB1 oftable DB1.TABAND I only want to update the row in DB2.TAB with the unique keyfieldIDOFTAB2 equal to variable @InputParameterDo you see what I'm doing wrong?--Thank you,Kind regards,Perre Van Wilrijk,Remove capitals to get my real email address,
Can I roll back certain query(insert/update) execution in one page if query (insert/update) in other page execution fails in asp.net.( I am using sqlserver 2000 as back end) scenario In a webpage1, I have insert query into master table and Page2 I have insert query to store data in sub table. I need to rollback the insert command execution for sub table ,if insert command to master table in web page1 is failed. (Query in webpage2 executes first, then only the query in webpage1) Can I use System. Transaction to solve this? Thanks in advance
I need to figure out the correct update statement syntax for the following integration.
I have a "Performance Table" which i insert weekly performance numbers into for each store. The table is constructed w/ columns such as Store, Weekenddate, Sales, Refunds, #ofPatients
In a "Averages Table" i have every weekenddate for each store populated. So 52 Weeks for 10 stores = 520 Rows of Store numbers & WeekendDates.
What i would like to do is run a loop or update statement which would update the store average for each weekendate based on the last 13 weeks.
This is my query
update performancestore_avgs set SalesAvg = (select sum(SalesHit)/Count(Store) from performance_store where performance_store.weekenddate >= performancestore_avgs.weekenddate-84 and performancestore_Avgs.store = performance_store.store)
The update statement runs but the averages are completely wrong.
SELECT SUM(PTR_QUANTITY) OVER (PARTITION BY PTR_SYMBOL ORDER BY PTR_DATE, PTR_SEQUENCE) AS 'ACUMULADO' FROM MPR_portfolio_transactions ORDER BY PTR_SYMBOL, PTR_DATE, PTR_SEQUENCE
This select statement generates one line per existing record. And what I would like to do next is to UPDATE the field 'PTR_ACUM' with the result of the 'ACUMULADO'
2 Users in 2 locations issue updates to the same table. 1 updating 1 column and the other updating another column. Now in reality the actual Stored Procedure issuing the update statement is passed in all the possible columns that could change and builds an update statement that updates all columns even the ones that havent changed.
Will this break Merge Replications conflict tracking? Or does SQL Server 2005 Merge Replication pickup that in reality the 2 updates only in reality changed the values in 2 columns.
I am trying to create a stored procedure that will take a text value passed from an application and update a table using the corresponding integer value using a CASE statement. I get the error: Incorrect syntax near the keyword 'SET' when I execute the creation of the SP. What am I missing here? This looks to me like it should work. Here is my code.
CREATE PROCEDURE OfficeMove
-- Add the parameters for the stored procedure here
@UserName nvarchar(10),
@NewLocation nchar(5),
@NewCity nvarchar(250)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
Execute as user = '***'
DELETE FROM [SQLSZD].[SZDDB].dbo.Employee_Office_Assignments
WHERE User_Name = @UserName
INSERT INTO [SQLSZD].[SZDDB].dbo.Employee_Office_Assignments
I have a stored proc that contains an update which utilizes a case statement to populate values in a particular column in a table, based on values found in other columns within the same table. The existing update looks like this (object names and values have been changed to protect the innocent):
UPDATE dbo.target_table set target_column = case when source_column_1= 'ABC'then 'XYZ' when source_column_2= '123'then 'PDQ'
[Code] ....
The powers that be would like to replace this case statement with some sort of table-driven structure, so that the mapping rules defined above can be maintained in the database by the business owner, rather than having it embedded in code and thus requiring developer intervention to perform changes/additions to the rules.
The rules defined in the case statement are in a pre-defined sequence which reflects the order of precedence in which the rules are to be applied (in other words, if a matching value in source_column_1 is found, this trumps a conflicting matching value in source_column_2, etc). A case statement handles this nicely, of course, because the case statement will stop when it finds the first "hit" amongst the WHEN clauses, testing each in the order in which they are coded in the proc logic.
What I'm struggling with is how to replicate this using a lookup table of some sort and joins from the target table to the lookup to replace the above case statement. I'm thinking that I would need a lookup table that has column name/value pairings, with a sequence number on each row that designates the row's placement in the precedence hierarchy. I'd then join to the lookup table somehow based on column names and values and return the match with the lowest sequence number, or something to that effect.
Hi All,I have a database that is serving a web site with reasonably hightraffiic.We're getting errors at certain points where processes are beinglocked. In particular, one of our people has suggested that an updatestatement contained within a stored procedure that uses a wherecondition that only touches on a column that has a clustered primaryindex on it will still cause a table lock.So, for example:UPDATE ORDERS SETprod = @product,val = @valWHERE ordid = @ordidIn this case ordid has a clustered primary index on it.Can anyone tell me if this would be the case, and if there's a way ofensuring that we are only doing a row lock on the record specified inthe where condition?Many, many thanks in advance!Much warmth,Murray
END CONVERSATION DIALOG CONVERT(uniqueidentifier, '58C1A7AA-C0D7-DB11-B4C6-005056C00008')
using ICommand.Execute method, I got an error:
Incorrect syntax near the keyword 'END'.
I use SQL Native Client as OLE DB Provider.
In profiler I can see that my statement becomes like this:
exec END CONVERSATION CONVERT(uniqueidentifier, '903586ED-C0D7-DB11-B4C6-005056C00008')
So provider add 'exec' before my statement, maybe because NCLI don't know such statetment and thinks that it is a stored procedure call with the name 'END'?
Is there is a way to avoid it except of using following construction:
hi all, this morning i went mad trying to understand how to do something like this:
WHERE CASE @Variable1 WHEN 0 THEN T1.Field1 <= Value1 AND WHEN 1 THEN T1.Field1 >= Value2 AND WHEN NULL THEN T1.Field1 >= Value3 AND END T2.Field2=@Variable2 AND so on
Can i select the statement that should be executed? i tried even inserting all the WHERE clausoles into 3 different IF, but he continues showing me errors...
Honestly i have to say that i'm pretti noob at SQL...
I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian
Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.
I need to make some changes to tables in a database. To do this requires that I "alter table" and "drop constraint" All constraints drop properly, except one. The last one will churn away forever in query analyzer and never drop. I am unable to make the necessary changes until this completes. I am guessing that there is a data issue that is keeping the constraint from being dropped. Any ideas on how to proceed? Thanks!
I have an activex script which executes a query that never finishes. If I recompile the query in Management Studio before I run this step, then the step will *usually* work fine. This is the last step in a very long update process so the data has changed a great deal when this step executes.
The query always works fine in Management studio btw.
I am using BI studio to run the package.
I have tried placing a step before this that marks the query for recompilation but that doesnt seem to work. Any ideas how to resolve this?
i was tasked to created an UPDATE statement for 6 tables , i would like to update 4 columns within the 6 tables , they all contains the same column names. the table gets its information from the source table, however the data that is transferd to the 6 tables are sometimes incorrect , i need to write a UPDATE statement that will automatically correct the data. the Update statement should also contact a where clause
the columns are [No] , [Salesperson Code], [Country Code] and [Country Name]
i was thinking of doing
Update [tablename] SET [No] = CASE WHEN [No] ='AF01' THEN 'Country Code' = 'ZA7' AND 'Country Name' = 'South Africa' ELSE 'Null' END

It appears to update only the first qualifying row. The trace shows a row count of one when there are multiple qualifying rows in the table. This problem does not exist in JDBC 2000.
I have a Conditional Split, where there are two outputs.
First output is a dataset which is to be inserted into the database.
Second output is a dataset for which the data already exists in the DB. I just need to update those data.
I have a doubt here. I want the insertion to be done first and then updation. Is there any property to be set for insertion or updation, something that maintains the order of execution or priority of execution.
Please do ask me if you need any further clarification.
Curious if I have the code below as an example and I execute this code does sql execute from top to bottom? And does the Update run and complete before the delete occurs? Or does SQL execute the update and delete in parallel?
I have a trigger on a table. I am trying to dynamically log thechanged fields on the table to another table, so I am iteratingthrough the bits in COLUMNS_UPDATED() to find what's changed, andgetting the column name programatically. This is all working fine.If I do a regular insert command in my trigger then everything worksfine. However, since I want to retrieve data from the column namewhich I got programatically from the inserted and deleted tables (toget the old and new values) I wanted to do something like this:insert into auditTransactionLog (TableName,PrimaryKeyId,ColumnName,OldValue, NewValue, ActionType) EXEC( 'SELECT(''cmContactInfo''), I.contactID,'''+ @colname+''', D.'+@colname+',I.'+@colname+', '+@action+' FROM inserted I INNER JOIN Deleted D onI.ContactId = D.ContactId')The presence of this line of code appears to be preventing theupdating of the table with the trigger. Is there some reason why Ican't do the EXEC in the trigger? If I did it without EXEC it worksfine but I have no idea of getting at the D. and I. @colname columnsotherwise.Thanks for any help!Rebecca
I'm writing a fairly involved stored procedure. In this Stored Procedure, I have an update statement, followed by a select statement. The results of the select statement should be effected by the previous update statement, but its not. When the stored procedure is finish, the update statement seemed to have worked though, so it is working.
I suspect I need something, like a GO statement, but that doesnt seem to work for a stored procedure. Can anyone offer some assistance?
I have a package which truncates files, fills them with data andshould send a mail with the files as attachment when it finishesrunning. In between, when the task is still running mail is sent withempty files. When I take a look at the directory (at the end of thetask), where the files are created I find out that the files are notempty.(e.g. in task: doA->doB->doC->SendMail. But instead of waiting tilldoB->doC finishes, it does the following: doA->SendMail ... may bebecause doB takes long.)Can I indicate anywhere that it should delay the mail until at the endof the task?Thanks in advance.Harp
Here is the situation I'm trying to set-up a package to ftp some files down if that part fails email me but if successful rename the 2 files to something else.
so what I set-up was a FTP tasks with the remote path set as a expresion since I needed to Download todays files. no problem there have that part working.
so then I set a notifaction event with failure constraint to email me. pretty easy so far.
then I set 2 tasks to rename the 2 files downloaded I'm sure I could do this part with a loop but what seperate tasks so I knew if any failed or could set-up notifaction tasks if I wanted. in the 2 rename tasks I set the sourcepath to an expression so it would know to read todays files and they could change from day to day.
then the destination part is hard coded for now to a file name.
now here is were the issue comes in I go to save it and it says the files don't exist from the rename piece. well of course not they haven't been FTPed yet.
so I tried delayevaluation on both the file system tasks but a no go still errors.
What I need it to do is basically say wait till the ftp is run these files won't be there. any help in the right direction would be appreciated.
I'm new to using SQL Server. I've been asked to optimize a series of scripts that queries over 4 millions records. I've managed to add indexes and remove a cursor, which increased performance. Now when I run the execution plan, the only query that cost is a DELETE statement from the main table. It shows a SORT which cost 71%. The table has 2 columns and a unique index. Here is the current index:
ALTER TABLE [dbo].[Qry] ADD CONSTRAINT [Qry_PK] PRIMARY KEY NONCLUSTERED ( [QryNum] ASC, [ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = ON, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] GO
Question: Will the SORT affect the overall performance? If so, is there anything I should change within the index that would speed up my query?
I have a query which used to run fine on a rubbish SQL 2000 box in about a minute, but with SQL 2005 (SP2) it never finishes, even when left overnight. No errors in the logs or anything. It is the same database which was backed up from SQL 2000 and restored into 2005. Does anybody have any ideas?
