I am wanting to set up a trigger on our SQL server 2000 to create a sequential order line number in the OrderDetails table for OrderID.
I will be inserting data from an OrderLinesAdd table into the OrderLines table but want the LineNumber field to be incremented by 1 for each group of orders grouped by OrderID that I insert into the table eg.
I have just started using SQL so am not sure how I go about writing the code for the trigger ? It would seem like I will need to use the Max function in the code.
In SQL sERVER 2008, I have two fields - Depatment and Employees. I need to sort the result set by employee number ascending order, with following exception
1)when department number = 50 - the preferred order is Employee # - 573 followed by 551-572 (employee # belong to Dept 50 = 551-573)
2)When Department number = 20 – the preferred sort order is Employee # 213-220, followed by Employee # 201-213 (employee # belong to Dept 20 = 201-220)
INSERT INTO PurchaseOrder (PurchaseOrderDate, SupplierID) VALUES(@date, @SupplierID)
END
SET @POno = @@IDENTITY
RETURN
However, how do i make it that it will automatically adds item under the POno being gernerated? can i use a trigger so that whenever a Insert for PO is success, it automaticallys proceed to adding the items into the table PurcahseOrderItem?
I have table1 with orderID and demographic info. Table2 with orderID and items. I would like to have a results display like this: OrderIDDemographicInfo Item1Item2Item3....ect One line per order. When I do a join I displaying all items in different rows.

I have a large query that I am trying to debug in query analyzer.However, the errors I get have no line number or reference to wherethey are failing. How can I find out what line in the query is causinga particular error message to appear?ThanksJohn IveySouth Pike School District
When you get a server error message referring to a line number in ascript, is there an easy way to jump to the correct line? It's noteasy to count down in a big script or when there is a lot of whitespace.In WordPerfect we had a linenum macro that allowed you to enter theline number and it would jump to the line using the same countingmethod as the interpreter that generated the error message. Is theresomething similar with TSQL, or another way?Kerry

i have a huge stored proc which has about 8-9 cursors which move data from a few temp tables to the final tables...and also do lots of calculations in between..
anytime there is an error in the stored proc i have an error page which looks like this
********************** Server Error in '/WebApplication3' Application. --------------------------------------------------------------------------------
a very lengthy page...the numbers are prbly due to the print stmts of the results of some calculations... but my q is..is there any way to return the xact line number where the error occured in the stored proc instead of these infinite list of numbers...its taking pretty long time to go through the entire stored proc to isolate the error...
I have a matrix report that shows a certain columns and rows. I need a row counter to show me the amount of rows in that matrix but it doesn't count properly by using the expression: =Int(RowNumber("matrix1") -1) I actually don't have any idea on what this expression should be to fix the row count...to illustrate what I get in the report:
As you can see above, the row count numbers are not lining up at all, it starts at 1, then jumps 2 every count then all of a sudden jumps 5 per line...a pattern that is interesting but difficult to understand. The unique value in this matrix is that serial number but even though i group it by the serial number, it still gives me the funny Row count values.
Hello all Trying to delete some data from a SSCE (2005) DB produces the exception: SqlCeException There was an error parsing the query. [ Token line number = 1,Token line offset = 43,Token in error = C] Here is the code I am using
I'm trying to insert some values into an SQL Compact database on a WM6 device but there is something apparently wrong with my SQL statement...
The program is going to allow users to schedule an SMS message to be sent at a certain date and time. I'm using a database to keep track of the scheduled SMS messages. The database has 3 rows: phone number, message, and the date/time to be sent.
I'm guessing it doesn't like how I am trying to get the data from the different text boxes and the DateTimePicker to go inside the SQL command. Does anyone have any ideas on how to fix my SQL command or how to get data from a textbox and DateTimePicker to be inserted into a database a different way?
Can you help me with SQL issue I€™m stuck on? I wish to take source data that looks like this:
Invoic_num
Line_num
6658
0
6658
2
6658
8
7721
2
7721
3
And rebuild the line numbers like this:
Invoic_num
Line_num
6658
1
6658
2
6658
3
7721
1
7721
2
This seems completely impossible to me. So I was thinking that maybe a second procedure using update could be run against the table after the initial build.
maybe this is not a serious problem, but I tried for days to come toi a solution without success.
My Problem:
I have have several flatfile sources I need to import into a sql-server 2005 DB.
It is very important for me to have the original line number from inside the source file for each record. The rowcount transform doesn't fit in for this task, because it accumulates all rows until the end of the dataflow.
I tried script components and it works fine if i assume there are no errors in my source. then I simply could declare a local variable and count it up and add a custom collumn to my output. But for errors in my source this won't work, because a second script component won't know the actual value of a package level variable, which i use to store the value, because i am only allowed to access this variable in the post execujte method of the script.
Hello everyone, I'm having an issue with dynamically setting the Send Mail task's to field to decent sized recipient list(approx 15 email addys). The strange thing is that this same package works fine if I'm using a list of say 4 email addys. I have double checked everything I can think of....list is seperated by semicolons, each address looks good....and have ran script tasks to check my variables along the path of the package but so far have not found the reason. The error I get is below:
"The specified string is not in the form required for an e-mail address"
Also of note, these addresses are being populated from a table, that is then setting the To string of the send mail task via a seperate variable...that variable being populated from a foreach loop. Again, all of this works fine with a smaller recipient list. Any ideas?
The only thing I can think of right now is to run the send mail task within the foreach loop...but then I'll be sending a seperate email for each address and would like to avoid that if possible.

I have a table of transaction that includes student ids and dates. I need to select all records from the table and include a new value that is the sequential transaction numbered for each student with the oldest transaction for each student being numbered one, the next oldest numbered two and so on. So the result should look like student1, 10/1/2000, 1, student1, 10/15/2000, 2, student1, 2/12/2001, 3, student2, 9/1/1999, 1, student2 10/2/2000, 2, student2 , 12/15/2000, 3, student2, 11/4/2001, 4 and so on.
Hi, Can anyone tell me the order in which uniqueness constraints on indexes are enforced vs. when triggers are executed ? I have a unique constraint on an index and a trigger on the column on which the same index has been created. When a row is inserted, the trigger checks if the value for that column already exists in the table - if not, it inserts the row as is, else it gets the max() val of the column (based on another key column) and increments it by one, then does the insert. Creating an index across the two works fine, but if I set the Unique Values property for the index, subsequent inserts bomb out - yet there aren't any duplicates in the final table, as the trigger ensures this. Anyone got any ideas on this? My deduction is that the uniqueness constraint gets enforced before the trigger gets executed, but at the same time this *seems* illogical, as the row has not been inserted into the table at the point where the trigger is executed.
This procedure has been returning duplicate numbers. (Tested with scripts that called this proc and put value in a table.)
How can it return duplicates? Does the transaction Begin/Commit not guarantee transactional consistency?

We have an app that uses triggers for auditing. Is there a way to know the order that the records were inserted or deleted? Or maybe a clearer question is.... Can the trigger figure out if it was invoked for a transaction that "inserted and then deleted" a record versus "deleted and then inserted" a record? The order of these is important to our auding.
We are having trouble figuring out how to create a view for this scenario:
We have a status log table that holds an order number, statusdatetime, and statuscode. This table will have multiple status' for the same order number. I want to create a view that will give me the most current status (by statusdatetime) of each order number. This view would show: order number, statusdatetime, and statuscode.
When i process a order in table Orders_t i would like to check in storage_t if we defenetly have it in storage. .... if we have it in storage, i decrease the "amount" by 1 ..(amount -1), and process the order. Otherwise it will return nothing.
This is what i´ve come up with so far:
CREATE TRIGGER checkInStorage ON orders_t FOR INSERT, UPDATE
AS DECLARE @tOrderId char(3), BEGIN SET @tOrderId = (SELECT orderId FROM INSERTED)
--check if the amount in storage
IF EXIST(SELECT amount FROM storage_t WHERE orderId = @tOrderId and amount >= 0) BEGIN --if it return true, i update the storage by decrease the amount with one UPDATE storage_t SET (amount = amount - 1) WHERE orderId = @tOrderId END
How would I go about setting up a "mask" to automatically place the hyphen in phone numbers in SQL Server? I.e., the user types in an area code and then a hyphen automatically inserts and the cursor is on the next blank space. Thanks for the assist.
I've a system of users and let's call em subusers. Every User becomes an automatic generated login when entered into the database. Every subuser has a reference to his user and no login, cause only thr root in the chain is able to login. But when the user gets deleted, all subusers become a new user. I've done this with a trigger changing the superUser Value=0:
create trigger abc on Users AFTER DELETE as declare @h int SELECT @h = id FOM inserted UPDATE Users SET superUser=0 WHERE superUser=@h
Furthermore the trigger deletes all additionally data of the user. Since every subuser of the deleted user becomes a user himself for every subuser a new Login must be created. I'm using an update triger for this task:
1: create trigger userUpdate on Users After Update 2: AS 3: DECLARE @superold int 4: @supernew int 5: @name nvarchar(55) 6: @date smalldatetime 7: if UPDATE(superUser) 8: begin 9: SELECT @superold= superUser FROM deleted 10: SELECT @supernew=superUser FROM inserted 11: 12: if @superold <> @supernew 13: begin 14: if @superold = 0 15: begin 16: DELETE FROM UserLogin WHERE id=@superold 17: end 18: else if @supernew=0 19: begin 20: SELECT @name=Name,@date=Date from inserted 21: execute createLogin @supernew,@name,@date 21: end 22: end 23: end
The problem is in line 20 and 21, cause the values @name and @date containing only the last updated user(the last entry in the inserted table) thus only for the last user a new Login is created whereas the others become the state user but no login was created. What i need is a method to loop over all entrys in the tables inserted btw. deleted. Does anybody know how to achieve this, looping the tables and executing a stored procedure for every entry?
I have a table with a field that contains the record number. This field is an identity column that is needed to be compatible with old Clipper programs. I've to ensure continuity in the numbering. So I have to update those numbers each time one or several records are deleted. I was thinking of using a trigger but I'm quite novice in this domain and don't know how to do it. Does anyone have a solution for this problem ?
I need to add the row number or record number to the 'inserted' and 'deleted' tables in a trigger.
Among other things, I have tried-
SELECT 1 as rowId, i.* INTO #ins FROM inserted i if @@ROWCOUNT > 1 --if multiple rows, set row number begin
SELECT @pkWhere = coalesce(@pkWhere + ' and ', ' where ') + PKF.colName + ' <= i.' + PKF.colName FROM #primaryKeyFields PKF set @strSQL = 'update #ins set rowId = (Select Count(*) From #ins i' + @pkWhere + ')'
exec (@strSql)
end
-the above sets rowId for every record to the total instead of sequential. Keep in mind that this code is used to create a trigger for any table, hence I cannot specify any column names literally.
I have to build a database model, create tables and use triggers or/and procedures on it. It's about a library. Books are borrowed by students. They can make a reservation of a book.
I built the database model so far. My problem is how to represent following tasks:
- Students can borrow a maximum of 5 books at the same time. - bookings/book reservations should be later processed in the order they occurred. That is, who first flagged the book also gets the book/books first
I have following entities:
- Book - Book exemplar - Borrowed by (a table between the entities Book exemplar and Student) - Reserved for (a table between the entities Book exemplar and Student) - Student
How would you represent the tasks I mentioned above in terms of triggers or procedures?...
I have an assignment to make a library. Right now I'm at the point of implementing business rules. One is that I need to create a trigger that won't allow a member to exceed a certain number of loans at a time, based on their category (student = 5, Teacher =10 and Researcher = 20).
