Dec 14, 2004
Hi
I have a table strcutre as follows.This is like a many to many relationship between category and Article. Now i need to pick 3 recrord from each category which has a relavancy 1 sorted by Article date Desc. ie.. from the recent articles..

I have a large table with approx 250000 rows in sql 2000. I need toreturn this from an asp page but the query to return this amount ofdata causes the asp to time out before the query completes.Is there any way in ado (or another way useable from asp / vb) that Ican run the query and then fetch a number of rows at a time? I can thene.g. pass the first batch of rows back to the client and then call forthe second batch.Any thoughts appreciated.

I store data in a table using a column named InsertTimestamp which is a datetime format. I now want to report on rows by just the date. I have been able to do this by converting the datetime like such:
convert(varchar, inserttimestamp, 107)
This reurns the data correctly however is very ineffiecnet. DOes anyone know another easy way around this dilemna???

I have a table with following sample data:
**CategoriesIDs RegistrantID**
47 1
276|275|278|274|277 4
276|275|278|274|277 16261
NULL 16262
NULL 16264
NULL 16265
[code]....
I need to know :
1). which category has how many regisrtantids (like 277 has how many registrantids) 2). group the registrants by category so that i can find which registrants are in category 277 for example)
Do I need to create a function which generates a table from csv ? I have created a function but not sure if it will work in this situation with IN clause.

my source flat file has many rows per customer,
but I need to transfer it to database with only one row per customer and accumulated sales (and probably do other calculations and lookups).
I understand how to do stuff with derived columns, but how can I read source file first, calculate, group and then save to database?
As I understand, the script offers only processing row by row: Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
Thanks

Hi folks. Hope all the gurus including Brett,Pat Phalen, RdjBarov, r937 are fine. ;)
been so long to ask stupid question. Here's the question and i really need help on this.
i have data that tracks patterns of bus stops from one point to another.
like point a, to point b, point b to point c forms one pattern.
point a to point c , point c to point b should be a different pattern.
create table #journeypatterns (patternid int ,points varchar(100))
go
insert #journeypatterns
select 1 ,'a' union all select 1 ,'b' union all select 1,'c'
union all select 2,'a' union all select 2,'c' union all select 2,'b'
union all select 3 ,'a' union all select 3 ,'b' union all select 3,'c'
select * from #journeypatterns
patternid points
1 a
1 b
1 c
2 a
2 c
2 b
3 a
3 b
3 c
what i want is to get unique pattern value of sequence of points by grouping on patternid. if the sequence of points change, i need a unique value against that pattern.
like for patternid 1, sequence of points a,bc for example should be abc.
for patternid 2, sequence of points a,c,b for example should be acb.
again patternid 3, sequence of points a,bc for example should be abc.
i tried CHECKSUM_AGG which brutally failed in production because the checksum values for each single point when summed produce SAME result for different patterns.
select checksum_agg(binary_checksum(points)) ,patternid
from #journeypatterns
group by patternid
961
962
963
here patternid 2 should be different because sequence is acb. i know checksum is not the right approach for what i need.
I NEED A GENERIC FUNCTION, that marks the pattern differences, my ultimate goal was to create a procedure, whom a patternid should be passed, and it would result the NEXT patternid in the table which has the SAME ORDER OF point sequences.
now folks, i can do this holding all data into a temp table and write a cursor to traverse through each patternid and concatenate the sequence of points.
BUT, using this approach is the ugliest, as it has slow down the process badly and boss is not happy with the performance. the table holds a lot of data.
I NEED a query rather than a cursor on the fly to resolve this.
Here's the query i am using to get the current sequence of a pattern and then i have to search all sequences similarly against it.
declare @patternid int
set @patternid =1
declare @sequence [varchar] (100)
declare @id varchar(10)
declare cr_sequence cursor fast_forward for select points from #journeypatterns where patternid=@patternid
open cr_sequence
fetch next from cr_sequence into @id
while @@fetch_status = 0
begin
select @sequence = isnull(@sequence,'')+@id
fetch next from cr_sequence into @id
end
print @sequence -- next i have code to find the similar sequence for another patternid.... which is not mentioned here but is similar

i've to generate a notepad using this query in vb.net :
strSql = "Select count(*), d.ShareholderId, d.UsufructId, d.BnkAccount, b.SBMCode, " & _
"LTRIM(ISNULL(d.TitleCode + ' ', '')) + LTRIM(ISNULL(d.Forename + ' ', '')) + d.Surname as ShName," & _
"d.BankCode, (select count(*) from (select ShareholderId from dividend " & _
"where CompCode = 'L1' and PaymentMode = 'B' group by ShareholderId, UsufructId, " & _
[Code]....
In the select statement i need to select "d.amount" as well. When i do so, it ask me to insert it in the group by option or in an aggregate function.
Grouping by "d.amount" returns extra field as there can be 2 similar "d.shareholderId" but with different amount.
how to group the "d.amount" without having repetition in the "d.shareholderid" ??

SQL Server 2008.
From individual event logs I have generated a table where arrivals and departures at a location are registered per device. As there are multiple registration points, there might be multiple consecutive registrations per location.
If this is the case I need to filter those out and have one registration per location and in the result I need to get the earliest arrival and the latest departure of these consecutive rows.
Part of the table:
logIDdeviceIDArrivedDepartedLocationIDGrp1Grp2Grp
3485441082013-02-07 17:51:05.0002013-02-07 17:51:15.0005110
3492041082013-02-07 17:51:15.0002013-02-07 17:51:26.0005220
3500241082013-02-07 17:51:27.0002013-02-07 17:51:37.0003312
3508941082013-02-07 17:51:41.0002013-02-07 17:51:54.0004413
[Code] ....
So as long the field LocationID is the same in the next row, it needs to be grouped.
I have added the rows Grp1, Grp2, Grp in an attempt to get an unique grouping number with the following script in the select statement:
,ROW_NUMBER() OVER(PARTITION BY DeviceID
ORDER BY logID) AS Grp1
,ROW_NUMBER() OVER(PARTITION BY DeviceID, LocationID
ORDER BY logID) AS Grp2
,ROW_NUMBER() OVER(PARTITION BY DeviceID
ORDER BY logID)
-
ROW_NUMBER() OVER(PARTITION BY DeviceID, LocationID
ORDER BY logID) AS Grp
By subtracting Grp2 from Grp1 (Grp = Grp1 - Grp2) I hoped to get an unique group number for each set of equal consecutive locations, however the Grp2 column does not restart from 1 each time the LocationID changes: Grp2 in line 7 should have been 1 again, but it is 2 because this is the second row with LocationID = 3 in the list.

I've unpivoted some data and stored it in a temp table variable
idNumFreqDtFreqrn
16100120120101M2
16100120120101M3
16100120100101M4
16100120100101M5
16100120060101M6
16100120000929Q7
16100119990101A8
16100119970101M9
Using the above data, if two rows have the same FreqDt, I want to see the record with the lowest row number.
So it should look like the below
idNumFreqDtFreqrn
16100120120101M2
16100120100101M4
16100120060101M6
16100120000929Q7
16100119990101A8
16100119970101M9
I've used the below code to accomplish it
SELECT DISTINCT
CASE WHEN t2.idNum IS NULL THEN t1.idNum ELSE t2.idNum END,
CASE WHEN t2.FreqDt IS NULL THEN T1.FreqDt else t2.FreqDt END,
CASE WHEN t2.freq is null then t1.freq else t2.freq end
FROM @tmptbl as t1 LEFT JOIN @tmptbl as t2
ON t1.idNum = T2.idNum
AND t1.FreqDt = t2.FreqDt
AND t1.rn = (t2.rn-1)
After all this, I'm supposed to condense the result set to only include sequential frequency dates with unique frequencies.should look like below (this is where I'm stuck)
idNumFreqDtFreq
16100120060101M
16100120000929Q
16100119990101A
16100119970101M
answer is below:
SELECT T1.*
FROM @t as t1 LEFT JOIN @t as t2
ON t1.idnum = T2.idnum
AND t1.freq = t2.freq
AND t1.rn = (t2.rn-1)
WHERE t2.idnum IS NULL

I'm really stumped on this one. I'm a self taught SQL guy, so there is probobly something I'm overlooking.
I'm trying to get information like this in to a report:
WO#
-WO Line #
--(Details)
--Work Order Line Detail #1
--Work Order Line Detail #2
--Work Order Line Detail #3
--Work Order Line Detail #etc
--(Parts)
--Work Order Line Parts #1
--Work Order Line Parts #2
--Work Order Line Detail #etc
WO#
-WO Line #
--(Details)
--Work Order Line Detail #1
--Work Order Line Detail #2
--Work Order Line Detail #3
--Work Order Line Detail #etc
--(Parts)
--Work Order Line Parts #1
--Work Order Line Parts #2
--Work Order Line Parts #etc
I'm unable to get the grouping right on this. Since the line details and line parts both are children of the line #, how do you do "parallel groups"?
There are 4 tables:
Work Order Header
Work Order Line
Work Order Line Details
Work Order Line Requisitions
The Header has a unique PK.
The Line uses the Header and a Line # as foreign keys that together are unique.
The Detail and requisition tables use the header and line #'s in addition to their own line number foreign keys. My queries ends up looking like this:
WO WOL WOLR WOLD
226952 10000 10000 10000
226952 10000 10000 20000
226952 10000 10000 30000
226952 10000 10000 40000
226952 10000 20000 10000
226952 10000 20000 20000
226952 10000 20000 30000
226952 10000 20000 40000
399999 10000 NULL 10000
375654 10000 10000 NULL
etc
Hierarchy:
WO > WOL > WOLD
WO > WOL > WOLR
It probobly isn't best practice, but I'm kinda new so I need some guidance. I'd really appreciate any help! Here's my query:
SELECT [Work Order Header].No_ AS WO_No, [Work Order Line].[Line No_] AS WOL_No,
[Work Order Requisition].[Line No_] AS WOLR_No, [Work Order Line Detail].[Line No_] AS WOLD_No
FROM [Work Order Header] LEFT OUTER JOIN
[Work Order Line] ON [Work Order Header].No_ = [Work Order Line].[Work Order No_] LEFT OUTER JOIN
[Work Order Line Detail] ON [Work Order Line].[Work Order No_] = [Work Order Line Detail].[Work Order No_] AND
[Work Order Line].[Line No_] = [Work Order Line Detail].[Work Order Line No_] LEFT OUTER JOIN
[Work Order Requisition] ON [Work Order Line].[Work Order No_] = [Work Order Requisition].[Work Order No_] AND
[Work Order Line].[Line No_] = [Work Order Requisition].[Work Order Line No_]

First some explaination then the question. I have some users that legally or otherwise have gotten copies of SQL 2000 and installed it on thier local PC's. They are now using Enterprise Manager to connect to my database servers via IP and server name. They are using thier regular user id and passwords that they would use to log into the HR and Finance applications. For obvious reasons this is not a good thing. Now the question, can I some how restrict connections via EM to just thoses with an sa role? Or am I doing something else wrong or missed some hidden configuration.
Thanks in advance!

I have a table with UpdateDate field and I want this field to be populated when a new record is inserted or an existing record is updated using the getdate().
But I dont want the users who insert or update records in this table to have control over this field. Meaning the users should not be able to populate or update this field.
At the same time when the user inserts or updates a record this field should be populated automatically.
Can this be done. Please let me know.
Thanks

Hi all
Certain people in our company want to use Crystal Reports for data-processing. Problem is we want them to NOT be able to access data in databases within the live server.
Given that we use trusted connection to validate all kind of data-access, I am wondering if there is a way so that (via NT administration or via some SQL Server security features)
the live-server can refuse any connection request from the Crystal Reports application. At the moment the same group of people are allowed access to database (and should remain to be so) on this "live" server via some other applications (e.g. Microsoft Access).
Any advice is welcomed.

I have users logging into a sql database using sql accounts. I've created below a simplified example of three tables in my 100+ table database. I have a sql table that holds extra information about the sql users and two data tables. I would like to restrict which records the user has access to in the manufacturer and automobile tables. I know I can add the UserID column to these two tables, and then add the appropriate userID into the UserID column of the manufacturer and automobile tables. Hence records in the automobile table with userid X will not be seen by userid Y. My question is, how can I possibly avoid modifying 1000+ sql queries to reference the UserID column? It would save me a lot of time if I can filter the results a user gets based on thier sql login/userid.
+--------------------------+
+ USERS TABLE
+
+ USERID int
+ Name varchar
+ Telephone varchar
+
+--------------------------+
+--------------------------+
+ MANUFACTURER TABLE
+
+ MANID int
+ Name varchar
+
+--------------------------+
+--------------------------+
+ AUTOMOBILE TABLE
+
+ AUTOID int
+ Name varchar
+

I'm going through the SQLSecurity Checklist I found at sqlsecurity.com. One of the points it says to "Restrict to sysadmins-only access to stored procedures and extended stored procedures that you believe could pose a threat." It also lists a bunch of stored procs and extended stored procs that you should consider restricting to sysadmins only. I was wondering if someone could give me some pointers on how to do this? I would like to write a script that I could run on every sql server 2000 install that would do this. How could I ensure that every user does not have access except the sysadmins?
Thanks,
Chris

Would like to restrict the dates users can put as parameters. For example, I have a report showing all orders in year 2007. I have exposed Start Date and End Date parameters. When users click the 'View Report' button, the report will filter for orders where attribute EnteredDate is >= Start Date and <= End Date.
I want to restrict the users from entering a start date greater than today's date. Would also like to restrict them from entering an end date that is less than the start date parameter. How can I do this?
TIA.

Hi
We are developing some applications for Sunit computers (In-vehicle computers) which have limited memory . Because the applications display maps, the will consume alot of memory. Because of this, we want to restrict the amount of memory and other resources SQL Server Express uses to a minimum. I've tried setting 'max server memory', which doesn't help too much as this is only a limit on the SQL engine and not the sqlserver.exe process. What other settings and restrictions can I apply to limit memory consumption by the process?
We have considered using SQL Server Everywhere, but as it doesn't support ODBC (will there be any ODBC support?), we are not too happy about using it. As of now, we have no experience with OLE DB, and the application is MFC 6.0 so we can't take advantage of ADO.NET
Best regards

Hello everyone,
I have a design problem which I am hoping somebody can shed some light on.
I am running SQL Server 2000 using SQL authenticaiton (due to be changed to Windows authentication in the next 6 months). I have a table in my database which we shall call monthly. I want to restrict the ability to insert to the monthly table to 2 stored procedures (proc_abc & proc_xy) which I have written which do various other validation checks before it inserts the data into monthly.
Users with the Foo function assigned are able to execute proc_abc & proc_xy
I have written a VB application which can be used by users who are not familiar with SQL to be able to execute these stored procedures. (Must have Foo function in order to login to this application).
I want to restrict the ability to execute the stored procedures to users using the VB application only, and thus not be able to execute the stored procedure using Query Analyzer or such like for any Foo user.
Is there anyway I can do this?
One suggestion put to me is two split the functions. Have one function lets call it Top which can access the VB application and then have another function called Bottom which is able to execute the stored procedures. Only the VB app would have access to the Bottom credentials. But is this secure? Would I just hard code the credentials for the Bottom function user within the VB app? This doesn's seem a secure way of doing things to me.
Thanks for the help!

I want to provide access to one of my users to a database on the production server. I do not want this user to be able to view anything other than the tables in that database, or the other databases on my production server.
I gave him access to one DB - TestDB- and made him data_reader on that DB. I had set that as his default database. However, when he logs in using SSMS he can see from Object Explorer a listing of all the databases on that server, although he can't access any of those. This is an external user and I don't want him to see any of that stuff, including other objects (SPs, Views, etc.,) even within TestDB.
To summarize, I want to grant access to a windows user to see/select from ONLY tables in TestDB of my production server, and I do not want him to be able to see any objects other than tables of this DB from SSMS.

Hi
I'm building a data warehouse - my end users connect using Access via ODBC Microsoft SQL Server driver (2000.85.1117.00).
However, whenever they connect using Access via ODBC they get a huge list of sys and INFORMATION_SCHEMA views, in addition to the data warehouse tables they need to access.
How can I remove these sys and INFORMATION_SCHEMA views from the list of tables/views presented to the end user?
I've tried denying access by changing permissions to deny in the public role of the master database - I have also changed permissions in the public role in the data warehouse database. When I do this, the ODBC connection fails to retrieve any objects because it doesn't have access to sys.databases (and various other unspecified objects).
I'm stuck - help!

This is a slight re-stating from an older thread, which I think warrants some new discussion. The answer has always been that system administrators should have full access to everything on a system, including databases.
Although that is a logical position for internal IT departments it doesn't quite fit the model of systems with outsourced or external system support.
"If you don't trust your DBA, then you need a new DBA. They are in a position of authority for a reason and restricting that authority makes it impossible for them to do the job they are hired to do."
What about scenarios where you have local machine administrators that should NOT be given access to private data in a secured database, even though they need to be able to access and maintain everything else? And unfortunately some regulations are written about access to stored data whether encrypted or not...
In the modern world of Sarbanes-Oxley and PCI-DSS/CISP it is no longer so cut and dried. Especially where companies have software/hardware support contracts with third parties that require administrative access to other aspects of the systems.
So accepting that you might need someone to have administrative level access to the box but they should not be able to view the contents of a database installed on that box, what would you do?
Is there a way to create an adminstrative group that does not allow access to a specific named instance of SQL?
Is there a way to revoke access for one member of the administrators group only?
Thanks,
Ted
