NB: ON UPDATE is much needed.
How to manage the situation?
Please guide.

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
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.
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.
This function results in a table scan *GASP!!!!* (at least that's what the 'splain plan tells me when I run it in SQL Analyzer). Before I made it into the function, when I was testing the code in SQL Analyzer, it resulted NOT in a table scan, but rather a series of nested loops (the joins) and clustered index seeks...resulting in about 1/3 the total cost of the function.
I suspected originally that it was the TOP/ORDER BY that the function insisted upon, but even if I remove those, still get a table scan.
Wassup? Why does the function turn my cool lil' self-join into a table scan? Whut am I missing? Any thoughts? Disgusted Derisions? Hurled Insults? Bring it on!!! (please! ;) )
My predecessor did this in a similar project using a separate cursor for each portfolio by date, then looped through the dates, pulling in the per-portfolio index value and building the output table. I would rather avoid the cursors if I can.

Hi I have sql 2000/2005 installation path errors in some of prodution servers. Like we have standards that backup files should go to E: drive and data files to f: and log files to h:. Can any one help me in this issue what can be done with out reinstallation,
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:
This has probably been covered in other posts. I have been working with SSIS for the past month and I am trying to follow best practices on various items. Having worked with a different ETL tool prior to this, I am wondering what is the best approach to use for Connections and File Paths.
What I would normally do with DataStage for this would be to assign a Job Variable (and eventually Sequence Variable) of the type: Path. So, if I was developing a job I would create SourceFilePath, ErrorFilePath, etc. I would use these variables in a FlatFile or Dataset Stage. For instance I would assign a filename for a source as: #SourceFilePath#SourceFile1.txt. During execution the job would load the variable and then the filename would be: C:MyDocumentsDatafilesSourceFile1.txt.
When its time to move to another environment, I don't have to worry about changing values for file connections because it is managed dynamically by a config file or whatever method.
What is the best practice that emulates this behaviour for SSIS? I've been thick and can't get my head around this. Any direction to blogs or user sites would be great. Examples, even better!
I am trying to set up a TEST ENIVORNMENT for a reservation software package. I need this setup so that I can run various scheduling scenarios in order to optimize operations. Below I have been given instructions from the software vendor on how to set up my SQL database. However, I am a little confused on what to do for a couple of the steps. They are as follows:
***In SQL server 2000 enterprise manager on the test laptop, change the 2 path settings in the table SGCONFIG. The should be changed to C:StratagenAdept5Server. ** YOU WILL NEED TO DO THIS STEP EVERYTIME YOU RESTORE A BACKUP ADEPT5_CLASTRAN.BAK FROM THE PRODUCTION TO THE TEST ENVIRONMENT
QUESTION: How do you change the path settings on a table?
***Open the .udl files in the apps folder and the server apps folder and check to see that they are pointing to the test laptop server, not the production server.
QUESTION: What are the .udl files and how do you check to see if they are pointing at the test laptop server only?
Thanks sincerely for your help. I am trying to meet a deadline for a meeting tomorrow. Therefore, I am desperate. Please send me email. rtanner@clastran.com.

What are the SQL 2005 Upgrade Paths? For example, is there a direct in-place upgrade for SQL 6.5? SQL 7.0? Can someone provide a link please? Thanks in advance.
I have created over a hundred reports and each of them are scheduled to output a pdf. The problem is this was temporary and each week I would like to output the reports to a directory that is based upon time. For example, I have 13 groups of reports and each group has 9 reports. Each group has it's own directory and folder. IE group A would be saved in something like \client filesgroup aweekly reportsMar 17 2008. The next week the reports for the same group need to be saved in \client filesgroup aweekly reportsMar 24 2008. This would be the same for each of the groups; group A, group B etc.
The question is there a way to set these paths dynamically or at least iterate through the subscriptions and change the paths?
I have an ActiveX Script Task in SQL Server 2000. It chooses one of two possible success-paths depending on if a file exist or not. (Part of the old ActiveX Script for choosing next step is below)
I need to rewrite this for a Script Task in SQL Server 2005 but it seems like it doesn't have this functionality and objects.
Does anyone know how to write the code for choosing the next step in a Script Task or knows another way to solve my problem?
The package is not suppose to fail if the file is missing, it's must succeed and that's why I need two success-paths.

I am trying to replace the path section of filenames listed in a collumn of my database. The filenames are UNC paths, and all files have 8 digit filenames with the same extension (they are all tif images). The length of the paths in the filenames will change, however.
Here is what my old paths look like:
\imageimagesNYY-MMABCDEFGH.TIF
..and here is the new path (all of the images are being consolidated into one directory):
\als-imagealscom31imagesdbABCDEFGH.TIF
------------------------------------------------------------- I have tried using the following query to do this:
update image set filename=replace(filename,'\imageimages5 0-08','\als-imagealscom31imagesdb')
This returns insanely crazy results like 460239 row affected, when it should be about a thousand. -------------------------------------------- I have also tried the following:
update image set filename=right(filename,12) + '\als-imagealscom31imagesdb' where left(filename,21) = '\imageimages5 0-08'
This affects zero rows.
Please guide me down the one true path. My coworkers are clueless and I'm quickly running out of disk on the old box.
Ive just installed VS2005 Pro and SQL Server Developer edition.
Now I want to set the default paths for project, templates, settings. But I want for both VS and SQL files.
For example, right now the default folders for SQL Studio are:
.My DocumentsSQL Server Management StudioProjects
.My DocumentsSQL Server Management StudioSettings
.My DocumentsSQL Server Management StudioTemplates
.My DocumentsSQL Server Management StudioBackup Files
... and so on.
For VS Studio:
.My DocumentsVisual Studio 2005Projects
.My DocumentsVisual Studio 2005Templates
.My DocumentsVisual Studio 2005Code Snippets
... and so on.
I would like for all sub-folders(from SQL Server and VS) to be in one same folder(Development), for example:
.My DocumentsDevelopmentProjects
.My DocumentsDevelopmentSettings
.My DocumentsDevelopmentTemplates
.My DocumentsDevelopmentBackup Files
.My DocumentsDevelopmentCode Snippets
... and so on.
I have tried changing in each application´s options the default path for each one, pointing to each folder I listed above.
My problem is that both VS and SQL Server still keeps creating folders in the old locations, for example: ".My DocumentsSQL Server Management StudioProjects". This example happens when I create a new query, and try to save it, it automatically creates that folder.
It only works for a few of them, like the settings folder. Ive managed to create a single folder for SQL and VS setting files.
Is there a way I can join both Application folders? I want to keep both projects files in one folder, both setting files in one folder, and so on...
Currently I have an sql string which looks like this
INSERT INTO tblPDFFiles (fileType,PDFcontent) SELECT 'First test file', BulkColumn FROM OPENROWSET(Bulk 'C://Test.pdf, SINGLE_BLOB) AS BLOB

INSERT INTO tblPDFFiles (fileType,PDFcontent) SELECT 'First test file', BulkColumn FROM OPENROWSET(Bulk ' \test2008 estpdf.pdf', SINGLE_BLOB) AS BLOB

I'm curious if there's a "best practice" for setting up the data directories MS SQL will use for each operation? I've allocated independent disks for things like C: (OS), E: (DATA), etc etc etc but I'm not familiar w/ MS SQL to understand how DBA's commonly configure the folders under each unique disk for things like DATA, LOGS, BACKUP, INDEXES, and TEMPDB. Should I have an identically name folder as show below in my example?
You can see I've just mirrored the drive name to a new folder under the partition so data is being written to: F:DATA and E:LOGS. Is this considered correct / good practice? I assume naming the folder in each mount point to whatever I logically called the drive is correct but if I should change how I configure my drive paths above. I'm trying to learn common good SQL Server practices and while I work on properly installing SQL Server 2012/2014, I want to make sure I configure my partition names SQL will utilize correctly.

7 5 9 7 9 3 7 3 5 Of course, in general case not all found by the code loops are minimal. But this is exactly my approach: firstly find any possible loops (avoiding excessiveness!!), then, in WHILE loop, try to mark out minimal loop(s) from intersection of two non-minimal loops... seems it will be an interesting t-sql job.
I am on SQL Server 2008 R2. I have a table that contains a field called [Location]. In that field is a UNC path to the physical file on the repository. Is there a way in SQL Server that I can say give me the select sum([Location] UNC file) where criteria? I saw some posts about xp_filesize or xp_GetFileDetails, but I do not see them in master. I am unable to add anything and wondering if there is any native functionality that would allow me to accomplish this!?

do I need to place the file in a folder on the server instead of uplading it?
Does anyone know how to do a cascade update in SQL 2005 using the studio manager?Basically, I have a project table with a status column. If the status is set to 2, then I need to update another table that references the project id.
I have a Sql Server 2005 table with 3 fields, an ID field (primary key), a parent ID field, and Name. The parent ID references the ID field (foreign to primary - many to one) within the same table so that records can reference their parent. I would like to place a cascade delete on the ID field so that when the primary ID is removed it will automatically remove all those records with a parent ID that match. Sql server does not allow me to establish this cascade delete.I was considering a trigger instead but only know how tio use the AFTER paramter and not an alternative. Thanks
We are developing a new oltp application using SQL Server 2000 and are debating whether to use "cascade delets" or not. In earlier apps, we had issues using cascade deletes like someone deleted parent by mistake and all child records got deleted OR SQL Server crashed in middle of cascade delete and records were lost or performance became an issue when there were huge # of child records to be deleted,etc.
Are there any recommendations for/against using Cascade deletes and when to use and when NOT to use cascade deletes ?
Hello all, I am new to SQL and I was hoping someone could explain something to me about 'on update cascade'. I understand what 'on update cascade' does (i think) - it updates the child table when the parent table is updated. What i do not understand is that the 'on update cascade' works on the primary key of the parent table, but i was on the understanding that the primary key doesn't change often if at all so why would the 'on update cascade' be of use? Sorry for my ignorance and i realise i must be missing something simple but would be grateful for any help. Thanks
