Hi there,
I'm using a query to fetch data from a table where one of the criteria is IN(...) clause for the key column of the table.Now the data being retrieved is ordered by the key column of the table even though I haven't specified any order by clause.
I want to know if there a way in which the data being fetched is in the order of my IN(...) clause.
Thanx

hi,
I would like to know that, I have three instances of the same database at three different servers and I am trying to fetch the data from the select query. "select * from table_name"
I would like to know, whether the order of rows fetched by this query will be different on different servers of sql server or the same order of rows will be fetched.
For me the output is coming different on each server database with he same query . Pls let me know, is there any default order by or it takes it randomly.
Thanks

Hi,
I'm currently developing an application using C# and SQL Server Express, in which one of the functionalities is to allow the user to browse through the existing products, wether by browsing one by one (next, previous, first, last) or performing a search (by product name, id, etc.). I'm currently using the default DataSource and TableAdapter aproach, but I found out that when I execute the TableAdapter.Fill() method, all the data in the table is fetched... what with 10,000 records it takes a bit to perform, specially on slower connections.
So my doubt is, what would be the best aproach to solve this problem? I'm considering loading first position, and then when the user presses the next button I'd fetch second position, etc, this using ROW_NUMBER(). I could even cache every other 10 records or something like that. Since it is possible to know any records row number (as long as the records are ordered) it would even work when the user performs a search and goes directly into row number 5000 for instance.
Would this aproach be a good practice, because that's all I want, to do things the right way? Thank you for your time
EDIT: I've noticed that when creating a SqlDataReader there is the option to provide a CommandBehavior, but I'm not quite undestanding how this could be used, would some tweaking in this area do the job?

Hello All,
I have to fetch data in an ssis package from a set of web services. what is the best way of doing this?
The web services are session based, this means that multiple calls are needed to complete one operation. like one to log on, second onwards to execute calls, and the last one to log out.
(there is some cookie management also required to logon successfully into the web services).
Should we write a custom task which will fetch the data for us? Or just write a C# component which is invoked from SSIS?
Regards,
Abhishek.
Hi,
I am trying to fetch data from IBM DB2 to SQL Server 2005.
The problem I am facing is when I create the OLE DB Connection (I am using the "IBM DB2 UDB for iSeries IBMDA400 OLE DB Provider") and see the "Preview", I get "System.Byte[]" in a couple of columns for all the rows, instead of the actual data.
The datatype of the original field is "Byte Stream".
I have tried all options, but, failed. I believe there is something in the "Force Translate" property of the OLE DB Connection. Right now it is set to "65535". I am not sure if that needs to be changed.
I was earlier using a DTS package, where I used ODBC for connecting to the same database. In ODBC, there is a "Translation" tab where there is a check box labelled: "Convert binary text (CCSID 65535) to text".
When I check this box, I am able to see the data correctly.
But, now I have moved to SSIS and I am facing the same problem as I am not using the ODBC connection.
Please help.
Thanks and Regards,

Greetings everyone,
Heres my code for login verification, which is written in the login button click.
SqlCommand cmd = new SqlCommand("Select uid,pass from UserRegistration where uid='" + txtuname.Text + "' and pass='" + txtpass.Text + "'", con);
con.Open();
dr = cmd.ExecuteReader();
if (dr.HasRows) { <code......> }
Now, my problem is, the SQL Server 2005 is fetching rows without checking case. For e.g. if I enter a password as "MYSTERY" or "mystery" which is stored as "Mystery" in the database. The datareader shows positive in HasRows property. So, Can someone suggest me how to fetch case sensitive data from SQL SERVER 2005. Thanks.
I'm using ODBC 3.0 in code written in C.
I have an service that connects using a system DSN using the SQL Server 2000 driver. On my development system with SQL Server 2005 Express installed, the queries work fine. I prepare a statement and then bind the columns that will be in the result set. On my system, I get all the data as it should be but on a live system, I do not get the proper data for the last three rows. I don't get any error messages from the query or the column binding and there are also no extra information messages that I can retrieve.
The table is something like the following. The names are changed to protect the guilty.
CREATE TABLE DOWNLOAD
(
FIELD_1 NUMERIC( 6,0 ),
ID CHAR( 15),
FNAME( 30 ),
LNAME( 40 ),
CLIENT_ID NUMERIC( 9,0),
CLIENT_NAME CHAR( 50 ),
CODE NUMERIC( 4,0 ),
PHONE CHAR( 10 )
)
go
On my system, running the exact same binary code as the client machine, I get all of the data from all of the columns as it should be. The problem is when I run on a client's system, the CLIENT_NAME, CODE, and PHONE columns return null values even when there is data there. On my development system the SQL Server instance runs on the same machine. On the client's sytem I am connecting to a remote instance of SQL Server 2000 on another system on the network.
My quandry is what could be different between the two systems that is causing me the problems?

The query works with the following exceptions:
My issues are:
1. Avoid the "division by zero" error. This can occur if a school is closed for a day or if a smaller school has no absences for a day.
2. Avoid weekend dates. I need the query to display only weekdays

Hello,I have one application which is having written in asp.net & plain asp.I am having one button on asp page,when i will click on that button, then itwill execute one other asp page.And after the execution of that second asp page, I redirect it to someASPX page with some values.On the ASPX page, it will connect to the Database, and insert the values.Thus, sometime, the following error is occuring :"Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."Main thing is that i am testing it on my local machine, then also it is giving me this error ...Insert into statement is also not much complicated :just I inserted three values in one table.Is this occuring due to the mixer of asp & aspx??Plz give me some proper solution.I want it in efficient manner, because this application will be accessed by number of users at the same time.Plz help me.Thanks,Sandy

How can I avoid the usage of the DTC? Is there a way to say "this code is not within a distributed transaction"?

Here is a simplified example of a problem I am facing.
I have 2 tables: Tasks and Employees.
Tasks:
(Task_ID, Task_Name, Task_Type, Task_Requirement, Employee_ID)
Employees:
Emp_ID, Emp_Name, Emp_Specialty, Emp_Task_Cnt, Max_Task_Cnt
Requirements: Write a MS SQLServer 2000 Storeed Procedure to:
1. Update the Tasks table by assigning the task to an Employee.
2. Incrememnt the employee's Emp_Task_Cnt for each Task assigned.
3. Match the Employee to the Task by matching the Task_Requirement to the Emp_Specialty.
4. Do not exceed the employee's Max_Task_Cnt.
I have a working solution to the requirements, but it involves using cursor logic. For all the obvious reasons, I wanted to avoid using a cursor (or cursor-like looping structure) but could not figure out any other way to avoid processing the Task table one record at a time because of the: "4. Do not allow an Employee's Task_Cnt to exeed the Max_Task_Cnt."
Q: Is there a way to do this without using a cursor and still meet all of the requirements?
I'm trying to performance tune a procedure and am sort of being thwarted by caching.
When I first run the procedure, it takes a few seconds which is too long in this case. Subsequent executions in Management Studio are nearly instantaneous, though, which I imagine is due to caching and does not reflect the behavior of the procedure in production.
Is there a way to disable caching so that each execution of the procedure in Management Studio will be consistent and reflect the "first run" performance?
This query uses a cursor to fetch a parameter and pass it to another Stored proc. Is there a straightforward way to do this without using a cursor?

Using small stored procs or sp_executesql dramatically reduces the number ofrecompiles and increases the reuse of execution plans. This is evident fromboth the usecount in syscacheobjects, perfmon, and profiler. However I'm ata loss to determine what causes a compilation. Under rare circumstances theusecount for Compiled Plan does not increase as statements are run. Seemsto correspond to when there is no execution plan. It would seem to me thatcompilation is a resource intensive task that if possible (data and schemaare not changing) should be held to a minimum.How does one encourage the reuse of compile plans?Is this the same as minimizing compilation?Looks like some of this behavior is changing in SQL 2005....Thanks,Danny
View 3 Replies View RelatedI have a stored procedure spUpdateClient, which takes as params a number of properties of a client application that wants to register its existence with the database. The sp just needs to add a new row or update an existing row with this data.
I tried to accomplish this with code somethign like this. (The table I'm updating is called Client, and its primary key is ClientId, which is a value passed into the sp from the client.)
IF (SELECT COUNT(ClientId) FROM Clients WHERE ClientId=@ClientId) = 0
BEGIN
-- client not found, create it
INSERT INTO Clients (ClientId, Hostname, Etc)
VALUES (@ClientId, @Hostname, @Etc)
END
ELSE
BEGIN
-- client was found, update it
UPDATE Clients
SET Hostname=@Hostname, Etc=@Etc
WHERE ClientId=@ClientId
END
But the client apps call this every second or so, so soon enough I started getting primary key violations. It looks like one client would make two calls nearly at the same time, both would get a 0 value on the SELECT line, so both would try to insert a new row with the same ClientId. No good.
So then I added
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
BEGIN TRANSACTION
at the top, and a COMMIT at the bottom. I thought the first one in would get to run the whole sp, and the next one in would have to wait for the first to be done.
Instead I'm now getting deadlock errors.
If I understand the docs right, that's because the exclusive lock is not placed on the Clients table until the INSERT happens, not at the SELECT. So when two calls to the sp happen at nearly the same time (call them A and B), A does the SELECT and that locks Clients so nobody else can update it. Then B does the SELECT, locking Clients so nobody else (including A) can update it. Now A needs to exclusively lock Clients to do its INSERT, but B still has that read lock on it, and they're deadlocked.
I could catch the deadlock in my client app after SQL Server kills one of the transactions, but it seems to me there should be some way to set a lock at the top of the sp that says "nobody else can enter this sp until I exit it". Any such thing?
Thanks.

Hello.
I have been developing a small site that has two backend SQL Server databases. One for my application data and one for the ASPNETDB database that is created by the ASP .NET Configuration utility.
Is it possible to configure the ASP .NET Configuration tool to use my custom database instead of creating a second database called ASPNETDB?
Thanks in advance.

I am exclusively using Stored Procedures to access the database, i.e. there are no Ad-Hoc SQL statements anywhere in the C# code. However, one thing I need to be able to do is to allow filtering for data grids on my ASP.NET page. I want to do the filtering in the Stored Procedure using Dynamic SQL to set the WHERE clause. However, one fear of mine is SQL injection from the client. How can I avoid arbitrary SQL injection, yet still allow for a dynamic WHERE clause to be passed into the stored procedure?

Hello all,
I currently have an asp script that is generating a 12 month rolling report. From asp I'm running a for loop with 12 iterations, each one sending the following query:
select count(a.aReportDate) as ttl from findings f left outer join audits a on a.aID = f.auditID
where f.findingInvalid <> 1 and month(aReportDate) = " & Mo & " and year(aReportDate) = " & Yr
where the Mo and Yr variables are incremented accordingly.
I actually have 4 sets of data being pulled back to populate a graph, so this results in 48 queries with each page load! Obviously not ideal. So I'm hoping to reduce this to 4 queries. I was playing with the following in enterprise manager:
DECLARE @DT DATETIME
DECLARE @CNT INT
SET @DT = '10/31/07'
SET @CNT = 1
WHILE(@CNT < 12)
BEGIN
select count(a.aReportDate) as ttl from findings f left outer join audits a on a.aID = f.auditID
where f.findingInvalid <> 1 and month(aReportDate) = month(@DT) and year(aReportDate) = year(@DT)
SET @CNT = @CNT + 1
END
I haven't yet added any logic to increment the date, but my concern is that it looks like it is returning 12 separate results. Is there any way to combine this all into one resultset that will be passed back to my asp script? Hopefully this makes sense?
Suggestions on a completely different approach would also be welcome.
Thanks!
Hi,
Hope someone could help me in revising a long running query. Here is the query
select *
from table1
where classid is null
and productid not in (
select productid
from table1
where classid = 67)
In here table1 could have several occurance of productid in which productid could have different classid. The possible values of classid are: NULL,1,2,3,67. Basically I am looking for all records whose classid is null but should never had an instance in table1 where its classid is 67.
Do you have something like a "join" statment that will only include all records in the left table that is not in the right table?
Hope someone could help me with this. Thanks in advance.

MS SQL Server 2005
I have a table in our system that hold temporary data for doing calculations. It will process several million records in it. each time they forecast our products.....

Please advice. Thanks
I am trying to figure out an efficient way of comparing two tables of identical structure and primary keys only I want to do a join where one of the tables reveals values for records which have been modified and/or updated.
To illustrate, I have two tables in the generic form:
id-dt-val
For which the 'val' in table 2 could be different from the 'val' in table 1 - for a given id-dt coupling that are identical in both tables.
Does anyone know of an efficient way I could return all id-dt couplings in table 2 which have values that are different from those with the same id-dt couplings in table 1?
NOTE: I am asking this because I am trying to avoid explicit comparisons between the 'val' columns. The tables I am working with in actuality have roughly 900 or so columns, so I don't want this kind of a monster query to do (otherwise, I would simply do something like where a.id = b.id and a.dt = b.dt and a.val <> b.val) - but this won't do in this case.
As a sample query, I have the following script below. When I attempt the where not exists, as you might expect, I only get the one record in which the id-dt coupling is different from those in table 1, but I'm not sure how to return the other records where the id-dt coupling is the same in table 1 but for where modified values exist:
create table #tab1
(
id varchar(3),
dt datetime,
val float
)
go
create table #tab2
(
id varchar(3),
dt datetime,
val float
)
go
insert into #tab1
values
('ABC','01/31/1990',5.436)
go
insert into #tab1
values
('DEF','01/31/1990',4.427)
go
insert into #tab1
values
('GHI','01/31/1990',7.724)
go
insert into #tab2
values
('XYZ','01/31/1990',3.333)
go
insert into #tab2
values
('DEF','01/31/1990',11.111)
go
insert into #tab2
values
('GHI','01/31/1990',12.112)
go
select a.* from #tab2 a --Trouble is, this only returns the XYZ record
where not exists
(select b.* from #tab1 b where a.id = b.id and a.dt = b.dt)
go
drop table #tab1
drop table #tab2
go
I really dont' want to have to code up a loop to do the value by value comparison for inequality, so if anyone knows of an efficient set-based way of doing this, I would really appreciate it.
Any advice appreciated!

The C++ application calls the database to look up property data. Onetroublesome query is a function that returns a table, finding data whichis assembled from four or five tables through a view that has a join,and then updating the resulting @table from some other tables. Thereare several queries inside the function, which are selected accordingto which parameters are supplied (house #, street, zip, or perhaps parcelnumber, or house #, street, town, city,...etc.). If a lot of parametersare provided, and the property is not in the database, then several queriesmay be attempted -- it keeps going until it runs out of queries or findssomething. Usually it takes ~1-2 sec for a hit, but maybe a minute insome failure cases, depending on the distribution of data. (~100 milproperties in the DB) Some queires operate on the assumption the input datais slightly faulty, and take relatively a long time, e.g., if WHEREZIP=@Zip fails, we try WHERE ZIP LIKE substring(@Zip,1,3)+'%'. Whileall this is going on the application may decide the DB is never going toreturn, and time out; it also seems more likely to throw an exception thelonger it has to wait. Is there a way to cause the DB function to fail ifit takes more than a certain amount of time? I could also recast it asa procedure, and check the time consumed after every query, and abandonthe search if a certain amount of time has elapsed.Thanks in advance,Jim Geissman
