Good morning everyone I am writing a windows forms application that will work similar to the windows messenger popup. I need this application to display a message to the user whenever a record is added to table in my DB. Any help would be appreciated in explaining how I can check the DB for new records.
View 3 Replieshi,
I basically want the .net version of rs.eof
does anyone know what the code would be using the execute scalar method?
Thanks
I am trying to write a trigger that, on an update, will check to see if more than one record is being updated. If more than one record is being updated, rollback the transaction and print a message. If not, then commit the transaction and print an OK message.
My problem is I am having troubles writing this trigger. I will post my SQL trigger code so far.
I am new with Triggers, so any help or advice is appreciated.
Code:
CREATE TRIGGER trgPaperCheck
ON BOOK
AFTER UPDATE
AS
IF UPDATE(Paperback)
BEGIN
DECLARE @count AS INT
SELECT @count = COUNT(Paperback)
FROM Book
IF @count > 1
BEGIN
PRINT('Only one Book record can be updated at a time!')
ROLLBACK TRANSACTION
END
ELSE IF @count =1
BEGIN
PRINT('Paperback Updated')
COMMIT TRANSACTION
END
END
I can't seem to get this work. I'm using SQL2005
I want to check if a record exists before entering it. I just can't figure out how to check it before hand.

View 1 Replies View RelatedI've got two tables, one containing a list of company names(approx 10,000 records), the other containing a list of company employees (approx 30,000 records) joined by the CompanyID column.
I have a third table (approx 700 records) containing new employees to be added to the employee table. Each record in this table has the employees details plus the name of their company.
I want to write a query that will check each row in the third table to see if
a) the employee exists in the Employees table
b) the company exists in the Companies table and
c) the employee is listed under the correct company
The query should also handle any combination of the above. So if the company doesn't exist but the employee does, create the company on the companies table and update the appropriate record on the employees table with the new CompanyID etc. etc.
Oh, forgot to mention. The company names in the third table won't be exactly the same as the ones in the Company table so will need to use CharIndex.
Anybody got any ideas?
I'm trying to check which price grids are in use using the price grid_id, and seeing whether this grid_id exists in another query that checks all active contracts. If the grid_id is present (active) I want to return 'Yes', if not I want it to return 'No'.
There are 385 price grids, but my query is only returning the 315 that are active, and ignoring any that are not used. My code is below, how I can see all the records whether Yes or No:
Select distinct
pg.grid_id [Price Grid],
pg.grid_name [Grid Name],
case when exists
(Select
c.grid_id from
customers c
inner join deltickhdr dh on dh.acct = c.custnum and dh.stage <5
where
c.type = 'C' and
dh.dticket is not null) then 'Yes' else 'No' end [Active]
From gridhdr pg inner join customers c on c.grid_id = pg.grid_id
Order by pg.grid_id
I am checking to see if the source record is available in the target table using a lookup transformation and if not found i have to insert this record.
I have connected the error flow of the lookup transformation to the target. I am acheiving expected results, but is this the best practise? I have not connected to the green arrow to any task.
I've decided to post this as a sticky given the frequency this question is asked.
For those of you wishing to build a package that determines if a source row exists in the destination and if so update it else insert it, this link is for you.

Hello,
I have an SSIS package that affects data in fourteen tables. This SSIS packge is supposed to insert, update, delete and apply various business rules to the data in the new database tabes in the same way that it occurs in the DTS package that affects the old tables in the former database.
After both the DTS packge and SSIS packages are run, the data in the fourteen tables from both databases need to mirror each other. I figure this is the best way that I can know that the new SSIS package is working correctly.
Is there something I can do in an SSIS package that can compare all of the tables between the two databases, record for record then (maybe as error output) produce output in the case where a mistmatch was detected between two given tables? Would a lookup transformation be helpful for this kind or thing, or should I think about doing it some other way?
The old database is on SQL Server 2000, and the new one on SQL Server 2005 64 bit. I've run into problems creating a linked server between the two to where I could just run queries to do this kind of check.
Any ideas?
Thank you for your help!

I have a table with a user column and other columns. User column id the primary key.
I want to create a copy of the record where the user="user1" and insert that copy in the same table in a new created record. But I want the new record to have a value of "user2" in the user column instead of "user1" since it's a primary key
Thanks.
Hey all!
Sorry for the less then descriptive post title but I didn't find a better way to describe it. I'm developing an app in the express editions of VB and SQLserver. The application is a task/resource scheduler. The main form will have a datepicker or weekly overview and show all tasks scheduled per day. The problem is, I've got one or more people assigned to tasks and I wonder what's the best way to design this. Personally, I'd go for one Task table, a People table and a table that provides a link between them (several record per task, one for each person assigned linking TaskID and PplID). However, I don't see a nice way of showing this data to the end user, allowing him to edit/add etc on ONE screen.
To fix that the only way I see is just add columns to the Task table for every person with select boxes. This way everything can be done on one simple screen. This obviously does present some future issues.
On top of this, which people are available on a day varies and there should be an option to allow a user to set who is available on a specific day. Which would lead me to my first idea and add another table that would provide this. but then I'm having design issues again for the form.
I'm kinda stuck atm, can anyone shed some light on this. I'm sure there is an elegant way of doing this but I'm failing at finding it.
Thanks in advance,
Johan
Hi,
We're running a Sage CRM install with a SQL Server 2000 database at the back end. We're using the Sage web services API for updating data and a JDBC connection to retrieve data as it's so much quicker.
If I retrieve a record using the JDBC connection and then try and update the same record through the web services, the query times out as if the record is locked for updates. Has anyone experienced anything similar or know what I'm doing wrong? If I just use DriverManager.getConnection() to establish the connection instead of the datasource, and then continue with the same code I don't get these record locking problems. Please find more details below.
Thanks,
Sarah
The JDBC provider for the datasource is a WebSphere embedded ConnectJDBC for SQL Server DataSource, using an implementation type of 'connection pool datasource'. We are using a container managed J2C authentication alias for logging on.
This is running on a Websphere Application Server v6.1.
Code snippet - getting the record thru JDBC:
DataSource wsDataSource = serviceLocator.getDataSource("jdbc/dsSQLServer");
Connection wsCon = wsDataSource.getConnection();
// wsCon.setAutoCommit(false); //have tried with and without this flag - same results
Statements stmt = wsCon.createStatement();
String sql = "SELECT * FROM Person where personID = 12345";
ResultSet rs = stmt.executeQuery(sql);
if(rs.next()){
System.out.println(rs.getString("lastName"));
}
if (rs != null){
rs.close();
}
if (stmt != null) {
stmt.close();
}
if (wsCon != null) {
wsCon.close();
}
I am attempting to create a multi-record file (as described in my last thread) and have found the following set of instructions very helpful:
http://vsteamsystemcentral.com/cs21/blogs/steve_fibich/archive/2007/09/25/multi-record-formated-flat-file-with-ssis.aspx
I have been able to create a sample file with two of my record types.
I now need to build on this further, because I have 9 record types in total that need to be extracted to a single flat file.
does anyone have any ideas how I might extend the example above to include more record types or know of another means of achieving this?
Thanks in advance for any help you might be able to provide.
Hi
Can anyone advise me as to how I can add the date and time to 2 columns in the sql server database for each record that is added. I'd prefer not to use the webform. Can sql server add the date automatically to the row?

Hi All,I have a table in SQL Server 2000 that contains several million memberids. Some of these member ids are duplicated in the table, and eachrecord is tagged with a 1 or a 2 in [recsrc] to indicate where theycame from.I want to remove all member ids records from the table that have arecsrc of 1 where the same member id also exists in the table with arecsrc of 2.So, if the member id has a recsrc of 1, and no other record exists inthe table with the same member id and a recsrc of 2, I want it leftuntouched.So, in a theortetical dataset of member id and recsrc:0001, 10002, 20001, 20003, 10004, 2I am looking to only delete the first record, because it has a recsrcof 1 and there is another record in the table with the same member idand a recsrc of 2.I'd very much appreciate it if someone could help me achieve this!Much warmth,Murray

Could anybody help me with the following scenario:
Table 1 Table2
ID,Date1 ID, Date2
I would like to link the two tables and receive all records from table2 joined on ID and the record from table1 that has the most recent date.
Example:
Table1 data Table2 Data
ID Date1 ID Date2
31 1/1/2008 31 1/5/2008
34 1/4/3008 31 4/1/2008
31 3/2/2008
The first record in table2 would only link to the first record in table1
The second record in table2 would only link to the third record in table1
Any help would be greatly appreciated.
Thanks
I've been looking for examples online to write a SPROC to get some data. Here are the tables.
Album_Category
AlbumCategoryID (PK, int, not null)
Caption (nvarchar(max), not null)
IsPublic (bit, not null)
Albums
AlbumID (PK, int, not null)
AlbumCategoryID (int, null)
Caption (nvarchar(max), not null)
IsPublic (bit, not null)
I need to return:
-[Album_Category].[AlbumCategoryID]
-[Album_Category].[Caption]
-[Albums].[Single AlubmID for each AlbumCategoryID]
-[Count of Albums in each AlbumCategory]
I hope I was fairly clear in what I'm trying to do. Any tips or help would be appreciated. Thanks.
I have a directory of user information. What I would like to do isallow someone to search for person X and then return not only theinformation for person X, but also the information for the next 15people following person X sorted alphabetically by lastname.So if someone searched for the lastname = "Samson", it would return:Samson, JohnSaxton, GregScott, HeatherSears, Rebecca.... (15 names following "Samson) ...How do you in SQL return a record set of X records starting atparticular record (e.g. lastname = "Smith)?Thanks in advance.

Hello. I have a database with a record that has two columns locked. descrip1 and descrip2. they are both nvarchar(max) columns. These are the only two columns of the record that remain locked. I am certain no user is accessing the record. I have even moved a backup of the database to my testing computer and the lock still exists. How do I remove the lock from these two columns on that particular record.
I can edit these two columns on other records. I have researched "Unlock" on MSDN but it doesn't seem to apply to t-sql. Any help would be greatly appreciated.
Thanks. Gary.
I am trying to update a record in a table based off of criteria of another record in the table.
So suppose I have 2 records
ID owner type
1 5678 past due
2 5678 late
So, I want to update the type field to "collections" only if the previous record for the same record is "past due". Any ideas?
I have not yet succeeded in getting an aswer to this in a previous post, so I'll try again and rephrase the question
I have 2 fields, 1 called 'Created' the other 'Updated'
I would like to create a function, user procedure ,whatever in SQL something along the lines of...
FUNCTION myUID()
RETURN Date(Today)+Time(Now)+USERNAME
END FUNCTION
so that the value returned by the above pseudo code is something like '20080526T21:01:05.620SamL' where the date part is in yyyy0m0d format
I have got this working fine for the default 'Created' field but the calculated (and persisted) field comes up with something about being non-deterministic and refuses to play
Clearly something along these lines is a very straightforward requirement (I have it working fine in my 20+ year old database) , but have spent a week trying to get an answer (even from this forum) without success, so would be grateful for any help that you can provide me with to get round this barrier
Hi All,
I am trying to create package something like that..
1- New Customer table as OleDB source component
2- Lookup component - checks customer id with Dimension_Customer table
3- And if same customer exist : I have to update couple fields on Dimension_Customer table
4- if it does not exist then I have insert those records to Dimension_Customer table
I am able to move error output from lookup to Dimension_Customer table using oledb destination
but How can I update the existing ones?
I have tried to use oledb command but somehow it didnt work
my sql was like this : update Dimension_Customer set per_X='Y', per_Y= &Opt(it should come from lookup)
I will be appreciated if you can help me...
Hi,
How can we insert multiple records in a OLEDB destination table for each entry from the source table.
To be more clear, for every record from source we need to insert some 'n' number of records into the destination table. this 'n' changes depending on the record.
how is this achieved.
thanks.
Hi,
I want to assign a list columns to be the PK on a table. I don't know what this list of columns would be.How do I go about figuring that?
Sample Data
Col1...Col2...Col3..Col4
1...........2.......A......X
1...........2........B.....X
1...........2.......A......Y
As you can see Col1 & Col2 ONLY do not make up the PK. I need to include Col3 as well. My concern is I am not sure if I have a row like..
1...........2.......A......X reapeated lower down the order. So how do I figure the PK out?
Thanks
Can someone show me some C# code for detecting if a SQL row exists or not? This seems like a very typical action and I cannot for the life of me find a tutorial online that explains this step. In my code I'm either going to INSERT or UPDATE a record. I tried sending a SELECT command through a ExecuteNonQuery, but only got -1 as a response. Apparently ExecuteNonQuery does not work with SELECT. I then saw that T-SQL has an EXISTS keyword, but I cannot see anyway to use that from within C#.So...can anyone share the typical code they use to identify if a row exists or not within a database. I guess I was execting there to be some method available to do this sort of thing.

I've forgotten the character set that I've chosen when I was installing the SQL Server 7. Is there a way to check?
I'm currently using US English version of Windows NT4 and SQL7. But interestingly, all the data is in Japanes characters. It's actually for a Japanese website, and the front-end application is written in ASP. I remember reading somewhere that it is impossible to do certain type of sorting (by some particular order for the Japanese language) as it is limited by the choice of the language of the NT OS.
The type of sorting that I'm looking at is the grouping of 5-characters. One example is in http://www.forest.impress.co.jp/aiueo.html
Would this be possible with my current setup? Or would it help if I migrate over to Windows 2000? (I'd rather not move to Japanese NT4)
Your feedback and advice would be very much appreciated!
Hi,
Just a brief question. I have a script which does a number of insert statements. What I would like to do is determine if the insert statements were all successful. Aside from checking @@ERROR after every insert, is there a way to check if all the insert statements completed successfully?
Thanks,

I want to do a check to see if a number falls within a range specified by the user. Basically, they enter in a min and max value and I return a hit if a number falls inbetween.
I have having trouble with my SQL statement:
Code:
SELECT DISTINCT *
FROM Table
WHERE ( (0=0)
AND
(min.value <= Table.Value <= max.value) )
(This isn't my actual code, but just the logic)
It will return all the results everytime. Does anyone have any suggestions on what I could be missing here?
Thanks in advance!
