May Cause Cycles Or Multiple Cascade Paths Error With Only Two Tables
Apr 11, 2008
Hi,
I have two tables called a and b. a has one row called aId where aId is the PK. b has bId, aId_1 and aId_2 where bId is the PK and aId_1 and aId_2 both allow nulls.
If I have a relationship between aId and aId_1, and another relationship between aId and aId_2, where I set the delete rule for both to SET_NULL, then I get the error -
"may cause cycles or multiple cascade paths"
But its completely reasonable that I might wish to do this.
The funny thing is that under Visual Studio, I can create a Data Set with these tables and using the designer, I can set the both foreign key relationships to Delete Rule Set Null and everything works as expected.
So, I'm unsure now if I just need to set the Delete rules using the Dataset designer and not bother with them in the database itself.
Any comments?
Thanks,
Barry.

Hi there.I've been searching for this error specifically but I haven't found anything yet.I have these two tables (USERS and REQUESTS):USERS ( [LOGIN] [varchar] (10) NOT NULL , [NAME] [varchar] (20) NOT NULL)where LOGIN is the primary key.The problem comes when I try to create the "REQUESTS" table.In these requests there's one user who types the request. After one or two days, there's other user who aproves the request. The problem is that I need two foreign keys referencing the table "USERS".CREATE TABLE REQUESTS ([ID] [numeric](5, 0) NOT NULL ,[DATE] [datetime] NOT NULL ,[NOTES] [varchar] (100) NOT NULL ,[TYPED_BY] [varchar] (10) NOT NULL ,[APROVED BY] [varchar] (10) NULL) ON [PRIMARY]GOALTER TABLE REQUESTS ADD CONSTRAINT [PK__REQUESTS__07DE5BCC] PRIMARY KEY ( [ID]) ON [PRIMARY] GOALTER TABLE REQUESTS ADD CONSTRAINT [FK__REQUESTS__TYP__15702E88] FOREIGN KEY ([TYPED_BY]) REFERENCES [USERS] ([LOGIN]) ON UPDATE CASCADE ,CONSTRAINT [FK__REQUESTS__APR__12742E08] FOREIGN KEY ([APROVED_BY]) REFERENCES [USERS] ([LOGIN]) ON UPDATE CASCADEAnd SQL returns:Introducing FOREIGN KEY constraint 'FK__REQUESTS__APR__12742E08' on table 'REQUESTS' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.Could not create constraint. See previous errors.Ok, after that, I tried creating a new table to store aprovals (Table with two fields: "REQUEST_ID" and "APROVED_BY").So, I removed "APROVED_BY" field from "REQUESTS" and its FK constraint.The same error comes up.I don't think this structure goes into "cycles" or "multiple cascades".How can I do this?Thanks in advanceRegardsRoland

Hello all,
Is there documentation somewhere about multiple execution paths in SSIS control flow? I didn't find documentation anywhere. I have a situation where I have two tasks that take considerable time, but could be executed in parallel (to speed up things) and I was wondering whether SSIS supports parallelism.
To illustrate the issues in simultaneous execution, I created a test SSIS package. In the package, I have five tasks, let's call them T1, T2, T3, T4 and T5. The taks are connected with "green arrows" like this:
T1->T2
T1->T3
T2->T4
T3->T4
T5 is not connected. The tasks can be e.g. Send Mail tasks, that's not relevant to this issue. I put a breakpoint in each task and execute the package.
When I execute package, T1 and T5 become active, i.e. the arrow that displays where the package execution currently is, is in two tasks simultaneously. Now F10 (step over) doesn't seem to work "Unable to step. Not implemented". If I press F5 nothing happens. After I press F5 for a second time tasks T1 and T5 and executed. Why don't they execute with the first pressing of F5? I would additionally like to know whether these two tasks are executed in parallel or sequentially, i.e. in the same thread or in two threads? Is there documentation of this?
The execution stops at T2&T3. Again, pressing F5 doesn't do anything, but the second time I press F5 T2 and T3 are executed.

Hi All,
Use Case1:
Just wanted to know if there is something like multiple cascade delete option in SqlServer 2005.
My table structure is similar to what is given below
create table test ( id int PRIMARY KEY, tname nvarchar(55))
create table childTest ( id1 int REFERENCES test(id) on delete cascade,
id2 int REFERENCES test(id) on delete cascade, tname nvarchar(55))......
The above creation fails for childTest since both id1 and id2 reference test with ondelete cascade.
As per Books online: The series of cascading referential actions triggered by a single DELETE or UPDATE must form a tree containing no circular references. No table can appear more than once in the list of all cascading referential actions that result from the DELETE or UPDATE.
Doesn't look like a circular reference here. Wanted to confirm if it is because test is being referenced twice in the childtable.
My requirement is if a row is deleted from test, it should delete matching rows from childTest(id1 and id2). Since delete cascade is not being allowed for both columns , I have to handle the delete in id2.
Use Case2:
Also can I have INSTEAD OF DELETE and Cascade delete on the same table?
I have a cascade delete from table1 to table2. which means when any row from table1 is deleted corresponding rows from table2 are deleted. and on table2 I would like to have an instead of delete where I would like to delete rows from another table say table3.
Thanks & regards
Sunil

Hi,
I have a self-referencing table, something like Emlplyee-Manager. I want to implement the cascading delete in this table. So when I delete a manager than all the employees should be deleted at ANY level below the manager.
I do not have DRI for the Foreignkey (manager)!!!
My problem is that the trigger fires only one time (for the "sons") and not for the "grandsons" and below.
I've used the following flags:
- nested triggers (in "SQL Server Properies", "Server settings" tabsheet)
- recursive triggers (database "Properties", "Options" tabsheet)
I've combined this 2 flags:
1. nested flag reset and recursive flag reset
2. nested flag reset and recursive flag set or
3. nested flag set and recursive flag reset
4. nested flag set and recursive flag set
The results are the following:
-for case 1, 2 and 3 the same results: the trigger fires just for the first level (the sons are deleted but the grandsons remains there orphan)
-for case 4 I have the following error message:
"Maximum stored procedure nesting level exceeded (limit 32)"
so I can't delete anything at all.
Any idea why the trigger doesn't fire for "grandsons" and below?
Could be that this above mentioned flags doesn't works for self-referencing tables ?
Thanks in advance

I am trying to pull in columns from multiple tables but am getting an error when I run the code:

The multi-part identifier "a.BOC" could not be bound.

Hi! I have a general SQL CE v3.5 design question related to table/file layout. I have an system that has multiple tables that fall into categories of data access. The 3 categories of data access are:
1 is for configuration-related data. There is one application that will read/write to the data, and a second application that will read the data on startup.
1 is for high-performance temporal storage of data. The data objects are all the same type, but they are our own custom object and not just simple types.
1 is for logging where the data will be permanent - unless the configured size/recycling settings cause a resize or cleanup. There will be one application writing alot [potentially] of data depending on log settings, and another application searching/reading sections of data.
When working with data and designing the layout, I like to approach things from a data-centric mindset, because this seems to result in a better performing system. That said, I am thinking about using 3 individual SDF files for the above data access scenarios - as opposed to a single SDF with multiple tables. I'm thinking this would provide better performance in SQL CE because the query engine will not have alot of different types of queries going against the same database file. For instance, the temporal storage is basically reading/writing/deleting various amounts of data. And, this is different from the logging, where the log can grow pretty large - definitely bigger than the default 128 MB. So, it seems logical to manage them separately.
I would greatly appreciate any suggestions from the SQL CE experts with regard to my approach. If there are any tips/tricks with respect to different data access scenarios - taking into account performance, type of data access, etc. - I would love to take a look at that.
Thanks in advance for any help/suggestions,
Bob

helloi need to write an sql which calculates # of billing cycles for anorder for which ive order start and end date. the first invoice willbe cut on the order start date.

Hello
I need to be able to regularly, update or delete data from my parent table and subsequent child tables from A to Z, each table contains data. However, I have having problems.
I have already created the tables with primary keys on each table and foreign keys linking each table to the next.
I tried to delete a row from the parent table and was given this error:
DELETE FROM [dbo].[DomNam]WHERE [DomNam]=N' football '
Error: Query(1/1) DELETE statement conflicted with COLUMN REFERENCE constraint 'FK_DomNam'. The conflict occurred in database 'DomDB', table 'Dom_CatA', column 'DomNam'.
I tried to insert an alter table query:
ALTER TABLE dbo.DomNamADD CONSTRAINT FK_Dom_ID
REFERENCES dbo.Dom_CatA (Dom_ID)
ON DELETE CASCADE ON UPDATE CASCADE
But on Execute I saw this error:
Error] Incorrect syntax for definition of the 'TABLE' constraint
What is wrong with the above syntax?
Or would it be better if I used a trigger instead because I already have foreign keys set within the tables?If so please give an example of the syntax for the trigger I would need to update and cascade data from all tables.
I would be grateful for any advice. Thanks.

We just upgraded from SQL Server 2000 to 2005. In the past, when I ran the import/export wizard to copy multiple tables from one database to another with SQL Server 2000, I had no problem. Now when I used the import/export wizard to copy multiple tables with SQL Server 2005, I kept getting an error. For example, when copied three tables, the first table might be copied fine and I got an error with the second table and the whole thing stop. Sometimes I could copy two tables. However, when I ran the import/export wizard to copy each table one at a time, it worked.
The error that I got was "Cannot insert duplicate key in object..." I selected the options to "Delete rows in existing destination tables", and "Enable identity insert". What am I doing wrong?

Hello,
I monitor a few "perfmon" counters which includes under the "system" object, "bytes transmitted/sec" and "file read bytes/sec". Every once in awhile, these counters will skyrocket, which can also be verified by the hard drive lights flickering like mad.
The only software installed on the machine is SQL Server 2K.
I was wondering if anyone knew how I could monitor within SQL 2K what process or user is using all of these cycles. If anyone could shed some light on this it would be greatly appreciated. Specifically, I would like to find out which database/query is doing this to minimize in the future as this affects all of the other connections.
Thanks in advance,
Brent.

I have a requirement where in i have around 15 different flat files , filenames are fixed but folder path can be changed(i think i should use a variable for folder path). These 15 files data should go to their respective tables in the database.
Whether I need to create separate data flow task for each file or separate package? In addition to these, example : while importing product data into product table, if product ID already exists, we need to ignore it and upload only the new records.

I have just taken over the job of sorting out a rather poorly designed database. It looks like it was 'upsized' from an access database to the SQL server. The SQL server is the 2000 version.
Now I am trying to generate a report of what the students in the database are owing by referencing the Receipt table and then all the available payment methods and allocations. I was wondering if there was anyway to work out data being displayed twice (Let me demonstrate)
Note1: All the tables are linked by a key of ReceiptNo. From what I can see there is a table for every payment type and allocation but no link between the two other then the receipt number.
Using the query:
SELECT T_Receipt.ReceiptNo, T_cheque.Amount AS Chq_Amount, T_credit.Amount AS Cre_Amount, StandingOrder.Amount AS Stn_Amount,
T_BankTransfer.amount AS Bnk_Amount, T_cash.TotalAmount AS Cas_Amount, T_RentPayment.AmountPayed AS Ren_Paid,
T_AdminPayment.AmountPaid AS Adm_Paid, T_InternetBilling.Total AS Int_Paid, T_Utilities.AmountPaid AS Util_Amount,
T_InvoicePayment.amountPaid AS Inv_Paid, T_OtherPayments.paymentAmount AS Oth_Paid, T_parkingBill.paymentAmount AS Prk_Paid,
T_TelephoneBills.TelephoneCredit AS Tel_Paid, T_DepositPayment.[Deposit payment] AS Dep_Amount, T_Receipt.cancelled AS Canceled,
T_Receipt.RemittanceReceiptNo AS Rec_Ref, T_Receipt.Student
FROM T_Receipt INNER JOIN
T_DepositPayment ON T_Receipt.ReceiptNo = T_DepositPayment.receiptNo LEFT OUTER JOIN
T_RentPayment ON T_Receipt.ReceiptNo = T_RentPayment.RentPaymentNo LEFT OUTER JOIN
StandingOrder ON T_Receipt.ReceiptNo = StandingOrder.ReceiptNo LEFT OUTER JOIN
T_TelephoneBills ON T_Receipt.ReceiptNo = T_TelephoneBills.ReceiptNo LEFT OUTER JOIN
T_parkingBill ON T_Receipt.ReceiptNo = T_parkingBill.ReceiptNo LEFT OUTER JOIN
T_OtherPayments ON T_Receipt.ReceiptNo = T_OtherPayments.ReceiptNo LEFT OUTER JOIN
T_InvoicePayment ON T_Receipt.ReceiptNo = T_InvoicePayment.receiptNo LEFT OUTER JOIN
T_cash ON T_Receipt.ReceiptNo = T_cash.ReceiptNo LEFT OUTER JOIN
T_AdminPayment ON T_Receipt.ReceiptNo = T_AdminPayment.ReceiptNo LEFT OUTER JOIN
T_BankTransfer ON T_Receipt.ReceiptNo = T_BankTransfer.receiptNo LEFT OUTER JOIN
T_Utilities ON T_Receipt.ReceiptNo = T_Utilities.receiptNo LEFT OUTER JOIN
T_credit ON T_Receipt.ReceiptNo = T_credit.ReceiptNo LEFT OUTER JOIN
T_cheque ON T_Receipt.ReceiptNo = T_cheque.ReceiptNo LEFT OUTER JOIN
T_InternetBilling ON T_Receipt.ReceiptNo = T_InternetBilling.ReceiptNo
GROUP BY T_Receipt.Student, T_Receipt.ReceiptNo, T_cheque.Amount, T_credit.Amount, StandingOrder.Amount, T_BankTransfer.amount, T_cash.TotalAmount,
T_AdminPayment.AmountPaid, T_InternetBilling.Total, T_Utilities.AmountPaid, T_InvoicePayment.amountPaid, T_OtherPayments.paymentAmount,
T_parkingBill.paymentAmount, T_TelephoneBills.TelephoneCredit, T_Receipt.cancelled, T_Receipt.RemittanceReceiptNo,
T_DepositPayment.[Deposit payment], T_RentPayment.AmountPayed, T_Receipt.Student
HAVING (T_Receipt.Student LIKE N'06%')
Which gives a result of:
RecNo.
30429
Cheque
250
Deposit
250
30429
679.98
250
This is fine but when I do analysis on this it appears as though the student has paid two deposit payments. I was wondering with out querying each table independently from an application if there was a criteria to specify that I only get one deposit result.
So as such say, give me all the payments but I only want one result from the other tables. I though about discrete but that wouldn't work here.

Hi!
I have 7 source databases and one target database, all using the same structure. The structure is made of 10 tables, with foreign key constraints.
I need to merge the source databases into the target (which won't have any data before that process, but will already have the correct schema), and to keep the relationships between the records.
I know how to iterate over the source databases (with SMO foreach), but I'd like to know if someone can advise the best copy method for that context in SSIS ? (I don't want to keep the primary keys, but I need to keep the relationships...)
Any pointer most welcome!
best regards and thanks

I have a couple of hundred flat files to import into database tables using SSIS.
The files can be divided into groups by the format they use. I understand that I could import each group of files that have a common format at the same time using a Foreach Loop Container.
However, the example for the Foreach Loop Container has multiple files all being imported into the same database table. In my case, each file needs to be imported into a different database table.
Is it possible to import each set of files with the same format into different tables in a simple loop? I can't see a way to make a Data Flow Destination item accept its table name dynamically, which seems to prevent me doing this.
I suppose I could make a different Data Flow Destination item for each file, in the Data Flow. Would that be a reasonable solution, or is there a simpler solution, or should I just resign myself to making a separate Data Flow for every single file?

I need to be able to bulk insert a bunch of tables from their corresponding flat file. I have created an XML file (see below) which has the file name/table name pair at each node. I then created a ForEachLoop task and used the Node enumeration type and the following OuterXpathString: ReferenceFiles/File. At this point I get lost. How do I pass the 2 inside node values (file name and table name) to variables which I can then use as expressions for the bulk insert task inside the Foreach?
Here is XML file:
Code Snippet
<ReferenceFiles>

<TableName>Ref_Categories</TableName>
</File>
<File>
<FileName>Ref_Configs.txt</FileName>

I used the data export wizard to export a single table to a single flat file (multiple wasn't allowed). I saved the package as a *.dtsx file which I'm attempting to edit to add the additional tables.
Creating additional sources is fairly easy copy of the first source and change to the table name.
I've tried copying the destination connection and changing to a new text file, but can't get past having to add each column manually to the new destination.
How can I duplicate the mapping that must be taking place in the wizard in the *.dtsx editing environment?
This seems like a simple / common task, but I've been unable to find a solution.
Thanks, Richard

@nationality (30),
@phone int,
etc
as
Select a.UserId, b.UserId, c.UserId FROM Table1 a, Table2 b, Table3 c

Hello,
I am in the progress of designing a new section of my database and was thinking of creating a hole new database instead of just creating tables inside the database. My question is can you JOIN multiple tables in an SQL Statement from multiple databases. Ie, In the Management program I have a database called 'Convention' and another one called 'Services', inside the two databases there are many tables. Can I link say tblRegister from Convention to tblUser in Services?
Thanks

Hi,
I have searched but not found quite the best way to look at this so far..
I have an application that outputs data to several text files (up to 30). These have commonality by an object name, but then contain completely different column data.
In DTS I had each of the source text file connections going to one OLE DB connection and then individual transform data tasks pointing to the one OLE DB connection.
Looking at SSIS, it would appear that I would need to have one source and one destination for each of these and therefore 30 parallel data flows?
Just wondering if there is a neater way of doing this??
It is a regular data import that happens a few times a day - the text files are named the same as the SQL tables - ie app_userdata.txt goes to app_userdata table.
Hope that explains ok and thanks in advance.
Mike

We have a growing issue where we have a relative dtsconfig file (which stores the absolute base path of the ETL packages). This way we can keep the ETL projects failry portable - only having to modify one value in the dtsconfig file. The master package that defines the dtsconfig location (which is config/Default.dtsconfig) usually interpretates this location to be relative the project. The problem is that every now and again when you open this package in .NETStudio, the path is interpreted differently and causes: config/Default.dtsconfig to state invalid path. But when we delete the variable (which defines the dtsconfig path), save/close and open/recreate it works again. This may or may not be supported MS method, but I was curious to know why this gets messed up. Is there somehwere in the .NET framework that defines what "/" is relatively under?
For example: Our absolute config path is "D:Program FilesMicrosoft SQL Server90DTSPackagesETLProjectETLBaseconfigDefault.dtsconfig" but using: "config/Default.dtsconfig" for xml file value works. However, sometimes we will get an error stating that this file cannot be found, and when we just try to delete (without saving and closing) and immediatelly try to put "config/Default.dtsconfig" again and hit next, we get an error and the path is now:
'D:Program FilesMicrosoft SQL Server90DTSPackagesDEVDataExchangeETLBaseconfigconfigDefault.dtsconfig'.
Ideas?

Hello all,
Being still a relative newcomer to SQL Server (people may say I'm trying to take on too much being somewhat inexperienced once they read about the problem I'm trying to tackle, but alas...) I'm running into the following problem: I need to create tables in my user database on the fly (using Stored Procedures) so that each table can be created many times in the database but only once for every user. The tables should be named something like "username.Table1", "username.Table2" etc. as opposed to "dbo.Table1". I then want to use the stored procedure from .NET/C# in my web application, so that i can create the complete set of usertables for each of my clients.
Now, I tackled the stored procedure part (that is, it creates all the tables I need with all the parameters I want) and am able to use it from my web application (which took some time to learn but proved quite easy to do), but I cannot seem to get it coupled to the current user (instead of the dbo). Every time I trie, the tables are created as dbo.Table1 and when I try to create a new set, it gives a warning ("table with name such and so already exists..."). I made sure to log in as an authenticated user (using forms authentication) before trying to create the tables but this gives the aforementioned result.
What am I doing wrong? I use Visual Web Developer Express, SQL Server 2005 Express and IIS version 5.1
Please help :-D
Greetingz,
DJ Roelfsema
