SQL Server 2008 :: Maintenance Plan Delete History Trying To Delete Wrong Files

Sep 11, 2015

I have some simple files but they are failing because the delete history task is failing as it is looking for files in a non existent directory.

It is looking for files in C:Program FilesMicrosoft SQL ServerMSSQL10_50.INSTANCEMSSQLLog whereas it should be looking in C:Program FilesMicrosoft SQL ServerMSSQL10_50.MSSQLSERVERMSSQLLog

how I can get this corrected so I can get the Maintenance Plans to run correctly.

I have tried deleting and recreating the Plan but to no avail

Master Data Services :: Hard Delete All Soft Delete Records (members) In Database

May 19, 2012

I am using Master Data Service for couple of months now. I can load, update, merge and soft delete data in MDS. Occasionally we even have to hard delete data from MDS. If we keep on soft deleting records in a MDS table eventually there will be huge number of soft deleted records. Is there an easy way to hard delete all the soft deleted records from all MDS tables in a specific Model.

Copy And Delete Table With Foreign Key References(...,...) On Delete Cascade?

Oct 23, 2004

Hello:
Need some serious help with this one...

Background:
Am working on completing an ORM that can not only handles CRUD actions -- but that can also updates the structure of a table transparently when the class defs change. Reason for this is that I can't get the SQL scripts that would work for updating a software on SqlServer to be portable to other DBMS systems. Doing it by code, rather than SQL batch has a chance of making cross-platform, updateable, software...

Anyway, because it needs to be cross-DBMS capable, the constraints are that the system used must work for the lowest common denominator....ie, a 'recipe' of steps that will work on all DBMS's.

The Problem:
There might be simpler ways to do this with SqlServer (all ears :-) - just in case I can't make it cross platform right now) but, with simplistic DBMS's (SqlLite, etc) there is no way to ALTER table once formed: one has to COPY the Table to a new TMP name, adding a Column in the process, then delete the original, then rename the TMP to the original name.

This appears possible in SqlServer too --...as long as there are no CASCADE operations.
Truncate table doesn't seem to be the solution, nor drop, as they all seem to trigger a Cascade delete in the Foreign Table.

So -- please correct me if I am wrong here -- it appears that the operations would be
along the lines of:
a) Remove the Foreign Key references
b) Copy the table structure, and make a new temp table, adding the column
c) Copy the data over
d) Add the FK relations, that used to be in the first table, to the new table
e) Delete the original
f) Done?

The questions are:
a) How does one alter a table to REMOVE the Foreign Key References part, if it has no 'name'.
b) Anyone know of a good clean way to get, and save these constraints to reapply them to the new table. Hopefully with some cross platform ADO.NET solution? GetSchema etc appears to me to be very dbms dependant?
c) ANY and all tips on things I might run into later that I have not mentioned, are also greatly appreciated.

Thanks!
Sky

SQL - Cascading Delete, Or Delete Trigger, Maintaining Referential Integrity - PLEASE HELP ME!!!

Nov 13, 2006

I am having great difficulty with cascading deletes, delete triggers and referential integrity.

The database is in First Normal Form.

I have some tables that are child tables with two foreign keyes to two different parent tables, for example:

Table A
/
Table B Table C
/
Table D

So if I try to turn on cascading deletes for A/B, A/C, B/D and C/D relationships, I get an error that I cannot have cascading delete because it would create multiple cascade paths. I do understand why this is happening. If I delete a row in Table A, I want it to delete child rows in Table B and table C, and then child rows in table D as well. But if I delete a row in Table C, I want it to delete child rows in Table D, and if I delete a row in Table B, I want it to also delete child rows in Table D.

SQL sees this as cyclical, because if I delete a row in table A, both table B and table C would try to delete their child rows in table D.

Ok, so I thought, no biggie, I'll just use delete triggers. So I created delete triggers that will delete child rows in table B and table C when deleting a row in table A. Then I created triggers in both Table B and Table C that would delete child rows in Table D.

When I try to delete a row in table A, B or C, I get the error "Delete Statement Conflicted with COLUMN REFERENCE". This does not make sense to me, can anyone explain? I have a trigger in place that should be deleting the child rows before it attempts to delete the parent row...isn't that the whole point of delete triggers?????

This is an example of my delete trigger:

CREATE TRIGGER [DeleteA] ON A
FOR DELETE
AS
Delete from B where MeetingID = ID;
Delete from C where MeetingID = ID;

And then Table B and C both have delete triggers to delete child rows in table D. But it never gets to that point, none of the triggers execute because the above error happens first.

So if I then go into the relationships, and deselect the option for "Enforce relationship for INSERTs and UPDATEs" these triggers all work just fine. Only problem is that now I have no referential integrity and I can simply create unrestrained child rows that do not reference actual foreign keys in the parent table.

So the question is, how do I maintain referential integrity and also have the database delete child rows, keeping in mind that the cascading deletes will not work because of the multiple cascade paths (which are certainly required).

Hope this makes sense...
Thanks,
Josh

Delete Syntax To Delete A Record From One Table If A Matching Value Isn't Found In Another

Nov 17, 2006

I'm trying to clean up a database design and I'm in a situation to where two tables need a FK but since it didn't exist before there are orphaned records.

Tables are:

Brokers and it's PK is BID

The 2nd table is Broker_Rates which also has a BID table.

I'm trying to figure out a t-sql statement that will parse through all the recrods in the Broker_Rates table and delete the record if there isn't a match for the BID record in the brokers table.

I know this isn't correct syntax but should hopefully clear up what I'm asking

DELETE FROM Broker_Rates

WHERE (Broker_Rates.BID <> Broker.BID)

Thanks

Help With Delete Statement/converting This Select Statement.

Aug 10, 2006

I have 3 tables, with this relation:
tblChats.WebsiteID = tblWebsite.ID
tblWebsite.AccountID = tblAccount.ID

I need to delete rows within tblChats where tblChats.StartTime - GETDATE() < 180 and where they are apart of @AccountID. I have this select statement that works fine, but I am having trouble converting it to a delete statement:

SELECT * FROM tblChats c
LEFT JOIN tblWebsites sites ON sites.ID = c.WebsiteID
LEFT JOIN tblAccounts accounts on accounts.ID = sites.AccountID
WHERE accounts.ID = 16 AND GETDATE() - c.StartTime > 180

Delete Statement

Apr 11, 2007

Hi,I would like to delete a record from a table on the condition that a corresponding ID is located in another table, ie. deleting an email message if the user ID is listed as a recipient in a recipient table etc. Here is my SQL statement: DELETE FROM id_email_message WHERE (id_message IN (SELECT id_message FROM recipients
WHERE id_user = 324) AND message.id_message_status = 2) OR (id_message IN
(SELECT id_message FROM message WHERE id_owner = 324 and id_message_status = 2)) The problem is the multiple select statements paired with the delete statement is too much overhead for the server and I always get a timeout server error (at least that's what I'm guessing, the error page and tracing isn't much helpful). Is there a more efficient way to do this?Thanks.Eitan

Help With DELETE Statement

Nov 13, 2007

Hello there... I'm creating a ASP.net Web Application and storing all my data in SQL database.I'm trying to create a Stored Procedure to Delete info from a table:- I have 3 tables: A, B and C:   A's primary key is aID and has no foreign key   B's primary key is bID and has 1 foreign key: aID (linking this table to table A);   C's primary key is cID and has 1 foreign key: bID (linking this table to table B);- As you can see, all 3 tables are linked (A to B and B to C)I want to be able to DELETE all info from C only by giving aID, is this possible in SQL? I can retrieve the info easily through a SELECT statement and using an INNER JOIN (*). I also know how to do solve this by coding it in C# but I'd have to create some unnecessary variables and more than 1 Stored Procedure when it's probably possible to do all in one!* SELECT cID FROM C     INNER JOIN B     ON B.bID = C.bIDWHERE A.aID= whateverIf anyone knows the solution to my problem, please don't hesitate :p Thanks,SuperJB

DELETE Statement

Dec 14, 2001

When does the DELETE statement physically deletes the records? For example, if I execute the DELETE statement and in the middle of the execution I understand that it is wrong. What will happen if I stop it? Will it delete the records partially? I think the deletion happens when the full statement is done but need an expert answer. Thank you.

How To Run Delete Query / Delete Several Rows Just By One Click ?

I'm using SqlDataSource and an Access database. Let's say I got two tables:user: userID, usernamemessage: userID, messagetextLet's say a user can register on my website, and leave several messages there.

Allow Single Row Delete From A Table But Not Bulk Delete

The requirement is: I should allow single row delete from a table but not bulk delete. An audit table should get updated if there is any single delete or single update. So I wrote the triggers as follows: for single and bulk delete

ALTER TRIGGER [dbo].[TRG_Delete_Bulk_tbl_attendance]
ON [dbo].[tbl_attendance]
AFTER DELETE

[code]...

When I try to run the website, the database error I am getting is:Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRANSACTION statement is missing. Previous count = 0, current count = 1.

Delete Doesn't Delete Rows, But @@ROWCOUNT Says It Did

Aug 20, 2007

I ran the following query in Query Analyzer on a machine running SQL Server 2000. I'm attempting to delete from a linked server running SQL Server 2005:

DELETE FROM sql2005.production.dbo.products
WHERE vendor='Foo'
AND productId NOT IN
(
SELECT productId FROM sql2000.staging.dbo.fooProductList
)

The status message (and @@ROWCOUNT) told me 8 rows were affected, but nothing was actually deleted; when I ran a SELECT with the same criteria as the DELETE, all 8 rows are still there. So, once more I tried the DELETE command. This time it told me 7 rows were affected; when I ran the SELECT again, 5 of the rows were still there. Finally, after running this exact same DELETE query 5 times, I was able to remove all 8 rows. Each time it would tell me that a different number of rows had been deleted, and in no case was that number accurate.

I've never seen anything like this before. Neither of the tables involved were undergoing any other changes. There's no replication going on, or anything else that should introduce any delays. And I run queries like this all day, involving every thinkable combination of 2000 and 2005 servers, that don't give me any trouble.

Does anyone have suggestions on what might cause this sort of behavior?

Cannot Amend Or Delete Subscription And Cannot Delete Report.

Nov 20, 2007



Hi,

I have a problem with one report on my server. A user has requested that I exclude him from receiving a timed email subscription to several reports. I was able to amend all the subscriptions except one. When I try to remove his email address from the subscription I receive this error:

An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help







For more information about this error navigate to the report server on the local server machine, or enable remote errors


Online no help couldn't offer any advice at all, so I thought I'd just delete the subscription and recreate it again, but I receive the same message. "Okay, no problem, I'll just delete the report and redeploy it and set up the subscription so all the other users aren't affected", says I. "Oh, no!", says the report server, and then it give me this message:





System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Data.SqlClient.SqlException: Only members of sysadmin role are allowed to update or delete jobs owned by a different login. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString) at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result) at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe) at System.Data.SqlClient.SqlCommand.ExecuteNonQuery() at Microsoft.ReportingServices.Library.InstrumentedSqlCommand.ExecuteNonQuery() at Microsoft.ReportingServices.Library.DBInterface.DeleteObject(String objectName) at Microsoft.ReportingServices.Library.RSService._DeleteItem(String item) at Microsoft.ReportingServices.Library.RSService.ExecuteBatch(Guid batchId) at Microsoft.ReportingServices.WebServer.ReportingService2005.ExecuteBatch() --- End of inner exception stack trace ---



What's even weirder is that I'm the owner and creator of the report and I'm a system admin and content manager on the report server and I set up the subscription when the report was initially deployed. Surely I should have sufficient rights to fart around with this subscription/report as I see fit?

I have rebooted the server, redeployed the report, checked credentials on the data source and tried amending and deleting from both the report manager and management studio but still I am prevented from doing so.

Any help would be much appreciated.

Thanks in advance,

Paul

DELETE Statement Conflicted

Dec 6, 2006

Hello
I am trying to delete a row from one table and I expected it to also be removed from the subsequent child tables, linked via foreign and primary keys.
However, when I tried to delete a row in the first table I saw this error:
DELETE FROM [dbo].[Names_DB]WHERE [LName_Name]=N'andrews'
Error: Query(1/1) DELETE statement conflicted with COLUMN REFERENCE constraint 'FK_LName_Name'. The conflict occurred in database 'MainDB', table 'Category_A', column 'LName_Name'.
I went to the very last table in the sequence and I was able to delete the row without problems, but it did not effect any of the other tables.
Please advise.
I need to make many changes in these tables, should I use a trigger instead, if so what is the code to trigger each table? I am new to triggers.
Thanks
Regards
Lynn

Only One Of My SQL Delete Statement Are Firing

Hey guys...
I am trying to tidy up my code a bit and have one SQL command (Sub class) to call when needing to insert, update, delete and select.
I have got one class I am testing with that delete from a table support_ticket and then calls RunSQL() again to delete the corresponding tickets in Support_Reply.
however it only seems to want to delete from one table at a time...as i commented out the first sql and it worked and the second fires...but if the first one is active it doesnt fire.
Do anyone on the forum know why this has happened?
 
Sub DeleteUserTicket(sender as Object, e as EventArgs)
Dim strSQL1 = "DELETE FROM Support_Ticket WHERE (TicketID = " & txtticketID & ")"
RunSQL(strSQL1)
strSQL1 = "DELETE FROM Support_Reply WHERE (TicketID = " & txtticketID & ")"
RunSQL(strSQL1)
End Sub
'One class to run the sql statements for the entire page this will reduce in repetitve code as well as reduce code size

Dim objCmd As SqlCommand
Dim sqlConn = New SqlConnection(strConn)
objCmd = New SQLCommand(strSQL, sqlConn)
objCmd.Connection.Open()
'Check that the rows can be deleted if not then return a error.

Delete Statement Very Slow

Dec 12, 2005

Hi,

I've got a table with about 500 000 records and growing monthly by about 40 000 records

When I perform the following query:

DELETE from [myTable] WHERE Month = '07' AND Year='2005'

This query will take about 10 minutes to execute. Columns Month & Year are both indexed.

Surely MSSQL can't be this slow on only 500 000 records.

Must I do some other database optimization ???

Thanks

                      (paths.links = '161') AND (relations.node2 = 162) OR
                      (paths.links = '162') AND (relations.node1 = 161) OR
                      (paths.links = '162') AND (relations.node2 = 161) OR
                      (paths.links LIKE '162%') AND (relations.node1 = 161) OR
                      (paths.links LIKE '%162') AND (relations.node2 = 161) OR
                      (paths.links LIKE '161%') AND (relations.node1 = 162) OR
                      (paths.links LIKE '%161') AND (relations.node2 = 162) OR
                      (paths.links LIKE '%161;162%') OR
                      (paths.links LIKE '%162;161%')
ORDER BY relations.node1 





Don't pay attention to the 161 and 162 things, is just test data, now my problem is that I want to transform that into a DELETE statement, but I can't find the right way to do it, so far I managed to do something like:


PHP Code:




 DELETE relations
FROM         relations INNER JOIN
                      paths ON relations.path = paths.path_id
WHERE     
                      (paths.links = '161') AND (relations.node1 = 162) OR
                      (paths.links = '161') AND (relations.node2 = 162) OR
                      (paths.links = '162') AND (relations.node1 = 161) OR
                      (paths.links = '162') AND (relations.node2 = 161) OR
                      (paths.links LIKE '162%') AND (relations.node1 = 161) OR
                      (paths.links LIKE '%162') AND (relations.node2 = 161) OR
                      (paths.links LIKE '161%') AND (relations.node1 = 162) OR
                      (paths.links LIKE '%161') AND (relations.node2 = 162) OR
                      (paths.links LIKE '%161;162%') OR
                      (paths.links LIKE '%162;161%') 





But that would delete only from the relations table and not from the paths table. I need to delete from both tables.

Can anyone help me please? Its kinda urgent.

Thansk!

Tuning A Delete Statement

Oct 26, 2004

Hi,

I need to delete the following records (from enrollment_fact):


SELECT
a."STU_SID",
a."SCHOOL_YEAR",
a."DATE_SID",
a."LOC_SID"
FROM "dbo"."ENROLLMENT_FEX2" b,
"dbo"."LOCATION_DIM" c
LEFT OUTER JOIN
"dbo"."ENROLLMENT_FACT" a
on c."LOC_SID" = a."LOC_SID"
WHERE
b."LOC_KEY" = c."LOC_KEY"
and
a."DATE_SID" between b."MIN_DATE" and b."MAX_DATE"


This is the approach (excuse the misuse of the concat function, but you get the idea)


DELETE FROM "dbo"."ENROLLMENT_FACT"
WHERE CONCAT (a."STU_SID", a."SCHOOL_YEAR", a."DATE_SID", a."LOC_SID")
IN (
SELECT DISTINCT CONCAT (a."STU_SID",
a."SCHOOL_YEAR",
a."DATE_SID",
a."LOC_SID"
)
FROM "dbo"."ENROLLMENT_FEX2" b,
"dbo"."LOCATION_DIM" c
LEFT OUTER JOIN "dbo"."ENROLLMENT_FACT" a
ON c."LOC_SID" = a."LOC_SID"
AND a."DATE_SID" BETWEEN b."MIN_DATE"
AND b."MAX_DATE")


comments? better way? (without using an sp)

thanks

Very Tricky Delete Statement

Apr 29, 2008

I have a rather tricky SQL delete query I’m trying to perform, preferably without cursors. I have the following data set, where I want each of the first changes to the status.

IDStatus
1Good
2So-So
3So-So
4Bad
5Bad
6Bad
7Bad
8Bad
9So-So
10Good

So given the above data set I would want to delete the following IDs: 3, 5, 6, 7, and 8. As they not the first in order. The problem is that while I can get isolate and save first instance of each status (in this case 1, 2, and 4), I can’t get the what I want. Is there a SQL way of accomplishing this.

How To Delete Row Number On Where Statement

Nov 7, 2013

I have duplicate rows of data with the exact same data, for multiple sets of data.For example,

1 Fred Flintstone
1 Fred Flintstone
2 Barney Rubble
2 Barney Rubble
etc...

If I use the delete and where command, it will delete both rows and I want to keep one of them. I don't want to copy down each one and re insert as there are too many columns for each one and there are too many rows also.I was thinking of a delete row-number command in a where statement. but tried multiple forums and its not working.
