Beginner @IDENTITY Question
Apr 29, 2004
Hello,
When I execute the following code on my localhost the INSERT statement is successfull and my ID is entered. But for some reason when I uploaded to my remote host the exact same database (MS SQL) and code it keeps trying to enter a NULL value into the ID column- which causes an error??? I don't understand becuase it is the exact same app and database but at a remote location.
Is @IDENTITY somehow saved in the session and my remote servers session settings?? are off?
strSql = "insert into Login (UserName,Password) VALUES ('" + UserName.Text.Trim() + "','" + Password.Text.Trim() + "') select @ID = @@IDENTITY";
Thanks in advance for any responses.

While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
TIA,

I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,
barkingdog
P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?

hi there. this is my first post on this forum. im new to SQLServer so please go easy on me. :)
i am trying desperately to call a stored procedure from within another stored procedure. if i post my code below could somebody tell me where i am going wrong. the SP i have written is executing OK but the OUTPUT parameter Id_User is coming back as null, whereas it should be giving my a value there. i have tried changing the line 'EXEC sp_User_I' for 'INSERT INTO @User_Id EXEC sp_User_I' but this wont compile.
CREATE PROCEDURE sp_Account_I]
@Username varchar(16),
@Password varchar(88),
@Surname varchar(32),
@DateBirth datetime,
@Email varchar(64),
@Id_Account int OUTPUT,
@Id_User int OUTPUT
AS
DECLARE @ErrorCode int;
BEGIN
SET NOCOUNT ON;
EXEC sp_User_I
@Username,
@Password,
@FirstName,
@Surname,
@DateBirth,
@Email,
@Id_Country,
@Id_User
...do some other stuff here for the account...

Hi all,
I've been banging my head against this issue, and I haven't managed to find a solution. I was hoping that maybe somebody here has done something similar.
I am trying to get the latest available pricing from a Rate table, which is based on the customer ID and the provided date from another table (Table1).
This is what the code looks like, essentially:
select
table1.*
,table2.*
,table3.Rate
from table1
left outer join table2 on table1.Id = table2.Id
left outer join (
Select Top 1 Rate from RateTable
Where RateTable.date < table1.date
order by RateTable.date desc
) as table3 on table3.custId = table1.custId
I understood that table1.date can't be explicitly passed into the nested join within table3, but does anybody know a work around that can achieve the above example (the environment is SQL server 2000 and inside a view not on in a stored proc)?
Thanks in advance for any tips or workaround.

My company needs a database. My first thought was to do it in Access, because it's available! But I wanted to check that that was smart, what its limitations are, when it's better to move to bigger / more expensive software, etc.
It's probably going to have several hundred thousand records in and will grow by more than a hundred thousand every year. Is there a size limit?
Not that many fields, though - it's not that complicated a database.
Many thanks in advance for any help :beer:

Hi all,
This looks like a great place for SQL Server support. I hope you don't mind a few n00b questions.
I'm a sysop whose main experience is with Windows XP and SBS 2003. I'm also reasonably familiar with Access 97/2000, having programmed a few small databases. I've recently acquired a client who is running the premium version of SBS, which includes SQL Server 2005. This means I have to manage this thing. This *huge* thing. So my first question is: Where can I find information to get me started, first from a sysop perspective, and later from a Access programmer perspective. What is your experience?
Then two current issues. One is that for some reason SQL Server 2005 is using about 2 gigabytes of memory out of the box. Is this normal? Second, I can't for the life of me find the backup system. I can see backups being made of the AdventureWorks database (at 3:00), but even after 2 hours of searching I can't change the schedule. I knew how to do this in SQL Server 2000, but this version is very different.
I'd much rather figure these things out on my own, but this product is just too complicated to learn in a few days, and the memory usage issue is critical.
I'd be much obliged for any help you can offer.

Hi,I'm finishing up a beginning SQL class where we learned on an Oracledatabase and the transition to working on SQL Server is easy. The next moreadvanced course will be in PL/SQL, but I know I will be working on SQLServer in the workplace, so my question is if I should take this course.Will I benefit from the basic philosophies that will be covered, or will itjust make a transition for me more difficult? Will it be partly a waste oftime and money and I'd be better served getting a book and self teachingmyself? I know that in a greater sense learning something isn't necessarilya waste, but I mean from the perspective of my goal of being able to use SqlServer, will this course be useful?thanks.

Also, when I run the server configuration utility in the DM add-in folder, do you know what I should put in the server name to get it to run off my hard disk and not a server? local host doesn't seem to work.

Hi all....
I'm not good t adatabases and never had to install one before, but I have an easy question....
I need to install a big application that needs a database server in the back end to run, I have a box with SQL2005 installed on it and I need to let the server be the database server for this application that will be installed on a seperate box....
How would I be able to point this application to the database server? do I need to install a SQL client on this server and point it to the SQL2005 server in the back?
Do I need to create a "new database" on the SQL sever and give it a name and credentials then point the application to that database? if that is the case, how would I do it?
Thanks.

I have created two reports. One links to the other with a drillthrough. The linking works fine, but no values show up in the fields besides the group titles and column titles. Why is this happening?
The user is given a list of Counties with values. The Counties(in a matrix) are clickable for a drillthrough of Ages and Genders in the Counties. Looks something like this:
Years
Counties Total Crashes Fatalities
Cook 85 98
Manchester 2850 258
Sagamon 987 526
So when a user clicks a county, such as "Cook", this is displayed
Years
Age Gender Total Crashes Fatalities
0-8 Female 25 8
Male 55 15
9-15 Female 850 258
Male 185 35
16-22 Female 87 526
Male 10 35
But I am getting this in :
Years
Age Gender Total Crashes Fatalities
0-8 Female
Male
9-15 Female
Male
16-22 Female
Male
Whats going on? Can anyone make any suggestions? Just to let you know its based off of an Analysis Services Cube and not relational tables.

Hello,
First off, I'm completly new to SQL.
I'm trying to create an insert command that uses a select command as a value.
INSERT INTO Activation.dbo.Selected (PID) SELECT PID FROM ElecDB.dbo.PTT WHERE Vendor = 'guy'
What I get from this is 5 rows updated which is what I wanted.
Although, I would like to insert a UserID from C# code or for now just 1151 for example.
I'm assuming that it would look something like this:
INSERT INTO Activation.dbo.Selected (PID,UserID) SELECT PID FROM ElecDB.dbo.PTT WHERE Vendor = 'guy' , 1151
but I am not even close.
Please help me with this.
Thanks,
Guy

I have a question that I am sure is an easy answer for the pros, but being a beginner I need a bit of help. My problem is I am trying to average multiple columns and return a single output. Here is an example of the data and layout that I am looking at, and what the intended results would need to be.
TradeAmt TradePrice
100 36.75
200 38.75
100 36.80
The desired results would be the average Trade Price (36.7625 in this case). The problem I am running into is taking into account both columns. I know in other programming languages you can create a loop to multiply the TradeAmt by TradePrice, add the value to the next set of TradeAmy x TradePrice, and ultimately average it out. Since I am new to SQL I am not sure of the best way to proceed, any advice would be greatly appreciated.

Hello,
I have two database servers that I am interested in sending messeges between them. I am not interested in security or encryption at this point, only a simple message sending and recieving.
Can someone please provide simple scripts for object setup (certificates, queues etc) and message send and recieve ?
a link to such a script will be great as well. I am just a bit lost understanding all the new concepts (certificates, service, service binding.....)
Thank you
I.

I need to restore multiple tables in a sequence. I am writing separate data flow for each table restore.
If there is any error in any of the table restore data flow, I want to write that error in a log file.
I am writing a script component in every data flow, which will get error code & error description, that i am writing in the log fie.
Is there a way to create a public reusable error logging script file, which we can call from every data flow and log only errors which we want?
Also want to confirm if the way i am doing is correct way or is there any easier/better way to achieve this?

I'd like to query my Tasks and TaskActivity Tables to return the following results:
Case Id
Estimated Hours
Total Hours
Remaining Hours
Because I'm an SQL novice, I've had to resort to a hack of creating three different views to get the results I want: I'm sure there's a better way (i.e. a single, well-formed query) but when I try that my numbers are all wrong.
Here's my hack to get the correct results:
First I have a view to get my Estimated Hours and CaseId from my TASKS table:
SELECT COALESCE (SUM(EstHrs), 0.00) AS EstHrs, CaseId
FROM dbo.Tasks
GROUP BY CaseId
Then I have a view to get my Total Hours and CaseId from my TASKACTIVITES table:
SELECT Tasks.CaseId, SUM(TaskActivity.Minutes / 60.00) AS TotalHrs
FROM TaskActivity RIGHT OUTER JOIN
Tasks ON TaskActivity.TaskId = Tasks.TaskId
GROUP BY Tasks.CaseId
Finally I have a third view (that I actually use in my program) to put it all together:
SELECT vTaskActual.CaseId, vTaskEstimates.EstHrs, vTaskActual.TotalHrs,
vTaskActual.TotalHrs - vTaskEstimates.EstHrs AS RemHrs
FROM vTaskActual INNER JOIN
vTaskEstimates ON vTaskActual.CaseId = vTaskEstimates.CaseId
Any help would be greatly appreciated, and, if this is not the correct forum for newbie questions like this, please let me know.
TIA,
Rob

I have table of three column first column is an ID column. However at creation of the table i have not set this column to auto increment. Then i have copied 50 rows in another table to this table then set the ID column values to zero.
Now I have changed the ID column to auto increment seed=1 increment=1 but the problem is i couldn't figure out how to update this ID column with zero value set to each row with this auto increment values so the ID column would have values from 1-50. Is there a away to do this?
