Treat Contiguous Records As 1
Jul 23, 2005
Hi,
How can I treat multiple, contiguous records as one record?
i.e.,
tblData(
a varchar,
t datetime
)
select * from tblData
order by a,t
then, for row n, if a(n) = a(n+1) and t(n) <= t(n+1) (seconds) then
treat record n as the same as n+1, discard record n+1 and continue,
else start again with the next row.
Anyone got an idea? Just writing this I'm thinking I'm going to have
to venture into cursor territory (new for me).
TIA

I'm using SSIS to migrate data from one system to another. This is a usual extract, transform, cleanse and load type task.
The error handling is critical to get right. E.g. truncation of data on one column should stop that row being loaded but for other columns I might be happy to carry on loading the row but record a warning.
I'm finding the error disposition a bit limiting. I really feel the need for an 'Issue Warning' disposition which will act the same way as 'Ignore Error' in that the row continues being processed but will in addition copy a row to a warning output so that I can write a message to a log file for someone to manually investigate and correct that item of data post the conversion. Alternatively it would be useful to specify a severity (at a column level) when redirecting error output. This way I can put logic into a downstream component which would treat the error row differently depending on the severity of the error.
Am I missing a trick?

Ok, I have a table with IP addresses stored in decimal format using both positive and negative numbers.
The way that they are stored is:
Positve
1 thru 2147483647 = 0.0.0.1 - 127.255.255.255
Negative
-2147483648 thru -1 = 128.0.0.0 - 255.255.255.255
Conversion
positive
x/2^24 . (x/2^24)/2^16 . etc . etc
negative
(x+2^32)/2^24 . ((x+2^32)/2^24)/2^16 . etc . etc
I have a script which works by using UNION and the WHERE statements are x>0 x<0
My problem is I need to use a 3rd party app to run the script (McAfee ePO). McAfee does not recognize the UNION. My question is, can I acheive the same results as the script below, without using UNION.
SELECT ReportFullPathNode.FullPathName,
cast(cast(IPSubnetMask.IP_Start as bigint)/16777216 as varchar) + '.' +

Hi,
I want to transfer the data from a excel spread sheet to sql server. I have used the oledb comand and it works fine, and i have also used the sqlbulkcopy and it transfers the data properly.
But in my excel spread sheet i have many columns with data as -0.76 or 0.76 or something like that but when it transfer it to sqlserver that particular column in sql server shows it as 0.00762711864406778
So how i can i tell sql server to display the data as 0.76 instead of 0.00762711864406778
any help will be appreciated.

On an SQL2000 Enterprise Edition with SP3 and 3.2 GB memory, I have restore around 700 databases from backup .bak files with no errors. Now, while in the process to restore (proc to restore with move statement) another 150 databases, following errors are encountered:
-------------------------
There is insufficient system memory to run this query.
WARNING: failed to reserve contiguous memory of size = 196608.

-------------------------
Is ther memory leaking and/or hardware related? the sql used only 1.8 gb mem and the whole system is using 2.4 gb mem. After reboot, same error appears in the middle of restoring 150 databases.
thanks

Hi all,
I'm trying to join an Address table's columns:
ID, AddressLine1, AddressLine2, AddressLine3, ..., AddressLine7
into a contiguous layout. The issue is some fields are empty.
so I might have:
id ad1 ad2 ad3 ad4 ...
1 aa __ vv __
2 __ xx __ __
3 tt rr __ ee
I need to turn it into:
id ad1 ad2 ad3 ad4 ...
1 aa vv __ __
2 xx __ __ __
3 tt rr ee __
I've done this up with a cursor, a user defined function, but I need to do it up 2 other way. My mind is blank - any ideas would be great

I have a SQL database that has multiple tables I need to combine for an analytics presentation. The tables are PRODUCTS (contains product information and UPC), STORES (Store number, name and address), DATES (List of dates that data is published on), and DATA (quantity, by store, by UPC, by date). I am trying to combine these so that i have one table with a row for each UPC on each day at each store. Also, I would like to lookup values for year ago quantities at the same store for the same UPC. Is there a way to structure a query to provide all of this information? I know it will be a lot of rows, but I will filter by product prior to pulling the data.
I think the solution requires a subquery in the FROM portion of the statement, but I am not sure how to structure it. Here are the Fields:
Products.UPC, Data.UPC, Data.Store_Num, Stores.StoreNum, Data.StartDate, Dates.DateKey, and finally the reason we are here Data.Qty
I am using an Azure SQL Database.

CREATE TABLE [#TEMP_WK_STOCK](
[WMNUMBER] [int] NOT NULL,

returns just 2 rows and misses the fact that the wmNumbers stop and start a few diffrent times. I cant see how to set up the query to bring back the 6 rows i would be expecting it this case, without going to a cursor which i really don't want to.

Hi
A very basic MDX question. Using the following from AdventureWorks as an example:
Code Snippet
WITH MEMBER [Measures].[Big Cities]
AS
(
[Geography].[City].&[New York]&[NY]
, [Measures].[Internet Order Count]
)
SELECT
[Measures].[Big Cities] ON COLUMNS
, [Customer].[Total Children].Children ON ROWS
FROM [Adventure Works]
How would I re-write the [Measures].[Big Cities] calculated member so it included both [Geography].[City].&[New York]&[NY] and [Geography].[City].&[Los Angeles]&[CA]? Assuming there is no logical connection between these members, and that they are non-contiguous. Also, in my real example, I cannot move [Measures].[Internet Order Count] to the WHERE clause, it must remain within the calculated member.
Thanks,
Julia.

I deleted some records out of an entity, I'd like to keep the Codes as contiguous and incremental, meaning no breaks between the code numbers.I created a business rule and applied it but codes remain the same.
I used the "Default to a generated Value" action, then selected the Code attrib. --Saved.
Then back to the Entity, I applied business rules. But nothing seemed to have happened. As there was no change in codes.
There are no validation errors either.

I have a situation where deleting old records is blocking updating latest records on highly transactional table and getting timeout errors from application.
In details, I have one table called Tran_table1 in OLTP database. This Tran_table1 is highly transactional table, it will receive data for insert/update continuously
While archiving 2 years old records from Tran_table1 into Tran_table1_archive in batches(using DELETE OUTPUT INTO clause), if there is any UPDATEs on Tran_table1,these updates are getting blocked and result is timeout errors in application.
Is there any SQL Server hints to avoid blocking ..

HI,
I have been trying to solve the locking problem from past couple of days. Please help mee!!
Scenario:
--------------
I have a SSIS package in which 2 data flow tasks. 1st data flow task deletes records from a 5 tables and the 2nd data flow task should insert records into 1 of the five tables after the success of 1st data flow task. This scenario runs in Transacation.
The above scenrio in the 2nd data flow task hangs in runtime. It does not complete. with sp_who2 command i could see that there is an intent share lock(LK_M_IS) on the table and the status is SUSPENDED.
I dont know how to come out of this locking. Please help.
Thanks ,
Sunil

I have a table with about half a million records, each representing a patient in my county.
Each record has a field (RRank) which basically sorts the patients as to how "unwell" they are according to a previously-applied algorithm. The most unwell patient has an RRank of 1, the next-most unwell has RRank=2 etc.
I have just deleted several hundred records (which relate to patients now deceased) from the table, thereby leaving gaps in the RRank sequence. I want to renumber the remaining recs to get rid of the gaps.
I can see what I want to accomplish by using ROW_NUMBER, thus:
SELECT ROW_NUMBER() Over (ORDER BY RRank) as RecNumber, RRank
FROM RPL
ORDER BY RRank
I see the numbers in the RecNumber column falling behind the RRank as I scan down the results
My question is: How to convert this into an UPDATE statement? I had hoped that I could do something like:
UPDATE RISC_PatientList_TEMP
SET RRank = ROW_NUMBER() Over (ORDER BY RRank);
but the system informs that window functions will only work on SELECT (which UPDATE isn't) or ORDER BY (which I can't legally add).

I have a query similar to the following. The intent of this query is to retrieve the top 6 records meeting the specified criteria (LOGTYPENAME = 'Process Status Start' OR LOGTYPENAME = 'Process Status End' ) based on most recent dates. Please keep in mind that I expect to return up to 6 records for each unique LogProcessName. This could be thousands of different LogProcessNames with up to 6 records for each.
1) The table I am executing against currently is very large in size and thus takes a long time to execute against. It would seem there must be a more efficient query to get the results I am looking for?
2) CTE doesn't work on SQL 2000. I need a query that does.
3) I cannot modify the database itself in the process.
;WITH cte AS (
SELECT [LogProcessName], [LogBody], [LogDate], [LogGUID], row_number()
OVER(PARTITION BY [LogProcessName]
ORDER BY [LogDate] DESC)
AS RN
FROM [LOGTABLE]
WHERE [LogTypeGUID] IN (
SELECT LogTypeGUID
FROM LOGTYPE
WHERE LogTypeName = 'Process Status Start'
OR LogTypeName = 'Process Status End' ) )
SELECT *
FROM cte
WHERE RN = 1 OR RN = 2 OR RN = 3 OR RN = 4 OR RN = 5 OR RN = 6
ORDER BY [LogProcessName] DESC, [LogDate] DESC
Does anybody else have any idea that would yield the results that I am looking for and take into account items 1-3 above?
Thanks in advance.

Hi, I have had this problem for a while and have not been able solve it.
What im looking at doing is looping thru my patient table and trying to organise the patients in to there admission sequence, so when patient "A" comes in and is treated at my hospital and is discharged and admitted to another Hospital within one day then patient "A" will get a code of 1 being there first admission.
then if patient "A" is admitted again but there admission date is greater than one day they get a code of 2 being for there second admission but will need to loop thru table looking for other admissions and discharges.
The table name is Adm_disc_Match_tbl
Basically what i have 4 fields.
Index_key = which is the patient common link (text)
ur_episode = this wil change for each Hospital (text)
Admission_datetime = patient admission date and time (datetime)
Discharge_datetime = patient discharge date and time (datetime)
example of data
Code: ( text )

Hi,
I have to search the records after the records populated.
I mean to say, i have displayed records in report, if i enter some strings in the textbox and clicked find, then it will highlight the particular records, instead of highlighting the values, is it possible to display only those particular records.
For example, say i have 50 records in a page,i entered some strings in the textbox and clicked find, then it will highlight the particular 5 records one by one which match the criteria i have entered in the texbox, instead of that i have to display only those 5 records.
Please tell me how to implement in this report,
Thanks and Regards

Ok, I'm really new at this, but I am looking for a way to automatically insert new records into tables. I have one primary table with a primary key id that is automatically generated on insert and 3 other tables that have foreign keys pointing to the primary key. Is there a way to automatically create new records in the foreign tables that will have the new id? Would this be a job for a trigger, stored procedure? I admit I haven't studied up on those yet--I am learning things as I need them. Thanks.

and Table2.Dimension in (Select Dimension from Table1)
In Table1 There might be 10 Groupid records all of which are different.

I am trying to write a query that will retrieve all students of a particular class and also any rows in HomeworkLogLine if they exist (but return null if there is no row). I thought this should be a relatively simple LEFT join but I've tried every possible combination of joins but it's not working.
SELECT
Student.StudentSurname + ', ' + Student.StudentForename AS Fullname,
HomeworkLogLine.HomeworkLogLineTimestamp,
HomeworkLog.HomeworkLogDescription,
ROW_NUMBER() OVER (PARTITION BY HomeworkLogLine.HomeworkLogLineStudentID ORDER BY
[Code] ...
It's only returning two rows (the students where they have a row in the HomeworkLogLine table).

I'm looking for a way of taking a query which returns a set of date time fields (probable maximum of 20 rows) and looping through each value to see if it exists in a separate table.
E.g.
Query 1
Select ID, Person, ProposedEvent, DayField, TimeField
from MyOptions
where person = 'me'
Table
Select Person, ExistingEvent, DayField, TimeField
from MyTimetable
where person ='me'
Loop through Query 1 and if it finds ANY matching Dayfield AND Timefield in Query/Table 2, return the ProposedEvent (just as a message, the loop could stop there), if no match a message saying all is fine can proceed to process form blah blah.
I'm essentially wanting somebody to select a bunch of events in a form, query 1 then finds all the days and times those events happen and check that none of them exist in the MyTimetable table.

I'm at a bit of a loss here. My T-SQL skills are not up to the task at hand here :(
I've got company records in one table and SIC codes that correlate to the companies linked by the company ID. So, I can run the query, but the output I get is multiple records for each company, because some companies have multiple SIC codes associated with them.
I understand how to get only one record, but what I want to do is create a result set that has all the SIC codes associated with one company. Possibly in a comma seperated list, that would count as one field.
Anyone have any idea how to bring back all the SIC codes for one company as one variable (or multiple variables, but in one record)?
Thank you very much for any help,

I cannot figure out how to write a sql statement to display the multiple records of multiple records. I know that doesn't make much sense so let me explain:
This problem involves two tables. They both reference (FK) data in a third table (tblDepartment).
Here are the fields and some test data in each of the two important tables:
=============
tblDepartment =============================
departmentIDuserID
-----------------------------
1user1
2user1
1user2
2user3
3user3
3user4
===========
tblRequest ========================================
requestIDdepartmentIDuserID
----------------------------------------
11user1
21user2
32user3
43user3
53user4
62user1
What I am trying to do is display all requests associated with the multiple departments of "user1". In the above example, I would want to see (after a select statement):
requestIDdepartmentIDuserID
----------------------------------------
11user1
21user2
32user3

We don't see the requests of user3 or user4 when the given request's departmentID is not a department associated with user1.
Hopefully someone out there understands this. I've never had to write a select statement like this before, so I'm having trouble wrapping my mind around it. Thanks for any help!

Hi,
I have one table which holds an ID, a name, and a parentID (which can either the same as the main ID or it's one of the other ID in that tbl)
At the moment I do a select on the records whos main ID is the same as the ParentID. This gives me an initial list of records who are the "Main" parent records (i.e they are not the child of any other record..
so far so good.
However, what I need to do is for each record work out if they themselves have any Child records. (only some have).
so at the mo I end up with a results set as this:
1 Boats
2 Jumpers
3 Trousers
4 Ships
What I want to end up is something like
1 Boats True
2 Jumpers False
3 Trousers True
4 Ships True
Where the true or false is if the record has any child records..
Any ideas?

I can't get my head around this:I want to select all IDs from table A that do not have a related record intable B according to some condition:Table A contains, say, Parents and table B contains Children. I want toselect all Parents that have no children called "Sally" (this is a noddyexample, reminds me of being at Uni again :) ).Any ideas?Thanks
