Hello,I hope you can help me.We have a SQL Server 2000 database at work, (which works with a VB6frontend) which grew to a considerable size, so one of my past colleaguessent me this truncate statement to use on the database.I ran it like this, and all appeared to be well, it shrank the database,Shortly afterwards, after I ran this I noticed something not quite right.for example, one of the tables we keep is a User_Admin table which has 50records in there, when I accessed this using the frontend it only showed 1record, and this happened with every table in the database accessed by thefrontend.The data in the tables is still there, but only shows one record through thefrontend.Can anyone help me, and check this statement I ran, as its weird that allthis happened after I ran this statement.Thanks,Jayne Hegersp_dboption PBTDEV,'trunc. log on chkpt.', truecheckpoint--sp_dboption sadev,'trunc. log on chkpt.', falsesp_dboption PBTDEV,'autoshrink', true--sp_dboption sadev,'autoshrink', falseDBCC SHRINKDATABASE (PBTDEV, NOTRUNCATE)
According to SQL Server 2005 Books Online, the RetainDays property specifies the number of days that must elapse before a backup set can be overwritten.
I do not quite understand the implication of this property. Say, if I set RetainDays = 1, is it mean the backup set from yesterday MAY BE overwritten? If it is 'may be', how does SQL Server determines whether to overwrite or not? I tried RetainDays = 1 to backup a dummy database, but my test.bak keeps growing, the old files do not seem to be overwritten. Besides, what is the implication of accepting the default RetainDays = 0?
I am trying to add a case/select/if statement in the text color property of reporting services. I want it so if the value of a variable is 1 then "GREEN" else "RED". Any ideas?
We desperately require the RetainSameConnection to be set to True on our ADO.NET - ODBC connection manager. Unfortunately RetainSameConnection always defaults back to False when you open the package.
* Is RetainSameConnection supposed to work for the ADO.NET - ODBC combination?
* Is it a bug that it defaults back to false for the ADO.NET - ODBC combination?
I am a little bit confused about Transactions, the connection string parameter "RetainSameConnection" and the execution of a child package...
I have a parent package, which should execute some child packages in a loop depending on a sql dataset. doing this using variables works fine. I am setting the variables for Source and Destination also and I am having a connection manager for source and destination in the parent package.
The child packages alos have source and destination connection managers depending on variables coming from the parent package.
I am forced to use transactions on the destination, to be able to rollback if an error occurs.
When I initiate the transaction in my parent, call the child package with its own connection manager depending on the variables coming from the parent package will it be the same Transaction in my child and will it be possible to commit the transaction?
If this is not a proper way to do it is there another way to handle this?
My package creates a set of #temp tables in Execute SQL Tasks that are then used for lookups in a data flow. All of the #temp tables are created using the same OLE DB connection manager, and all of the lookup transforms are using this same connection manager. I have set RetainSameConnection=true for the connection manager.
However, when the data flow task is caching the lookup rows in pre-execute, it fails on one of the #temp tables. The error message I receive is:
Invalid object name '#TempTableName'
When I watch what's happing in SQL Server Profiler, I can see that all of the lookup tables are being created within the same process. The caching is likewise performed by this same process, EXCEPT for the caching of the #TempTableName table. For some reason, when the caching of this lookup table is stating, I see a new login and the caching SQL is executed on this new login, which of course does not have access to the temp table created in the previous connection.
Does anyone know why the connection manager would be connecting a second time for this lookup?
Here is my issue I am new to 2005 sql server, and am trying to take my old data which is exported to a txt file and import it to tables in sql. The older database is non relational, and I had made several exports for the way I want to build my tables. I built my packages fine and everything is working until I start building relationships. I remove my foreign key and the table with the primary key will get updated for the package again. I need to update the data daily into sql, and once in it will only be update from the package until the database is moved over.
It will run and update with a primary key until I add a foreign key to another database.
Here is my error when running the package when table 2 has a foreign key.
[Execute SQL Task] Error: Executing the query "TRUNCATE TABLE [consumer].[dbo].[Client] " failed with the following error: "Cannot truncate table 'consumer.dbo.Client' because it is being referenced by a FOREIGN KEY constraint.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
I've seen variations on this question in this forum, but none of the suggestions work for me, so any ideas would be greatly appreciated!
I have a SSIS package whose function is to monitor a directory for flat files and distribute the information in these files into a SQL 2005 DB for further processing later. I've configured Transactions for the package as serializable and supported, and I have a ForEach container set to serializable and required. All SQL and Data Flow tasks take place within this container. I have a single Connection Manager to pull in the flat input file, and another for the connection to the SQL DB. This setup will function, and roll back if necessary, but I take a huge hit on the continual establishment of connections to the DB. If I set the retainsameconnection property on the SQL DB Connection manager, I get an error when executing my first Data Flow task to move data from the flat input file to working tables within the DB: 0xC001A004 - Incompatible transaction context was specified for a retained connection. If I turn off Transaction support, the retainsameconnection property works as expected.
I've been running Profiler Traces, and can verify that no connection has been established to the SQL Server prior to execution of this task, so it seems like the context should be OK. I would welcome any feedback, suggestions or alternatives.
i did a Stored Procedure to truncate a table. it contains lots of crap from testing the site. just a simple 1 ALTER PROCEDURE dbo.TruncateUploads
AS TRUNCATE TABLE Uploads but it says "Cannot truncate table 'Uploads' because it is being referenced by a FOREIGN KEY constraint." then i make NULL all foreign keys and try still cannot. then i did it manually deleting all records then can! but why can't i truncate it? isn't it the same as removing all values plus having the primary keys to start from 0?
How can i TRUNCATE my table (removes rows that were produced at testing), so that in the actual running the automated IDNumber for my table start with 1.
hi, I have two tables members table and orders table. I have 2 records in members table and zero records in order table. When I try to truncate members table I get an error message. cannot truncate table members,because it is being referenced by a FOREIGN KEY constraint.
this what blows my head, There is no records in orders table. so why would the constraint enforced when there is no data in the order table. I created same table in access and I was able to delete a member from the members table. any comments.
I have several very large tables and sometimes I need to clean them. It's known that TRUNCATE TABLE works much faster than DELETE, but impossible to use TRUNCATE TABLE on a table referenced by a FOREIGN KEY constraint... Is it possible temporary disable (not delete) constraints and after complition of TRUNCATE enable them ?
after removing all rows from RiverInStates Table using TRUNCATE and the command completed successfully.
when i tried to remove all rows from Rivers table , i got the following error.
"Server: Msg 4712, Level 16, State 1, Line 76 Cannot truncate table 'rivers' because it is being referenced by a FOREIGN KEY constraint."
i thought the error may be due to the "Fkriverinstates" FOREIGN KEY CONSTRAINT. so i DROPped the constraint with ALTER TABLE RiverinStates DROP CONSTRAINT Fkriverinstates
even after DROPping the constraint, im getting the same error can any one point out where the problem is?
what is the best way to truncate/delete records from a table at a certain time of the day...... i'm sure this is a simple ?, but i'm still learning sql.
I have somme users who need to truncate some tables owned by DBO. I know that only table owner or DBO can execute TRUNCATE TABLE but I don't want grant DBO permission to those users. Do you have any suggestion ? Thanks a lot.
If I have a truncate table statement in a stored proc, will my log backups be compromised due to the nonlogged operations. If so, what are my alternatives in case that I need to restore? Differential backups?
begin transaction truncate table Acounts select * from Accounts rollback select * from Accounts
The first select is returning 0 rows as expected. But after doing the rollback I expected to yet see 0 rows as truncate is not logged so cannot be rolled back. But to my suprise I see that there are rows.
So the rollback is rolling back the truncate table statement. Can someone please explain this????
I know that only the owner of a table can truncate it. I want a user to run a procedure that truncates a table. Both the procedure and the table are owned by dbo, however the system says that the user can't truncate the tables because she doesn't have permission. The user has dataread and datawrite global permissions, and I do not want to give her dbo perimssions. Is there a solution to this?
Is it possible to TRUNCATE a table and BCP data into the same table in one TRANSACTION? My problem is that I want to refresh(delete and via BCP append new data) a table without disturbing running applications. Can I run BCP from a SQL-script or a stored procedure?
Does anybody know of a way to allow non-administrators to execute the truncate table statement?
I have developers that from time to time need to move data between their databases usinge the DTS wizard. Most of their tables have identity columns and in order retain the identity seed, they need to click on the option to enable identity insert. This option isn't available to non administrators.
All of a sudden (!) I began to get this error whle attempting to run a multi-step job: This is during a very simple T-SQL statement.
Executed as user: EPRODSQLAdmin. Cannot TRUNCATE TABLE 'HR.dbo.Employee' because it is being referenced by object 'v_apps_Employee'. [SQLSTATE 42000] (Error 3729). The step failed.
Tables are being referenced by views all the time... Why would I begin to get this message?
The only thing I can think of is that I had just made my first "indexed view" ever, and it is in this database. Could that be related to the new error message?
I am trying to find a replication solution. It does not have to be real-time, but snapshot will not work since the database is too big. I was trying to configure Transactional replication. The replication itself worked good, but the Truncate table is not allowed in the transactional replication and merge replication. We have to use "Truncate table" in another processes during replication. Is there any other option or third party application I can use to do the replication with truncate table working. I tried Replication Exec, but it does not support 64bit system, which we have.
Hi group,In one of the books 'Gurus Guide to Transact SQL' i found this info:------------------------------------------------------------TRUNCATE TABLE empties a table without logging row deletions in thetransaction log. It can't be used withtables referenced by FOREIGN KEY constraints, and it invalidates thetransaction log for the entire database.Once the transaction log has been invalidated, it can't be backed upuntil the next full database backup.------------------------------------------------------------Does it mean that the log backup taken after table truncation is aninvalid backup?Help me! i'm lost....Thanks in advanceRonin*** Sent via Developersdex http://www.developersdex.com ***
Hi,I am trying to create a script that deletes transaction tables and leavesmaster data like customer, vendors, inventory items, etc. How can I useTRUNCATE TABLE with an Exists? My problem is I have 200+ tables, if Isimply use a list like:truncate table01truncate table02truncate table03....I get errors if the table does not exist and have to manually run thetruncate statements. Some tables may not exist if that part of the app isnever used. I'm trying to make a list of all tables that could existwithout it erroring out 50+ times.Thanks in advance.
I have a cursor looping through a list of tables that I want totruncate and then do a bulk insert into, Is this possible in SQLServer 2000 or do script each table individually.Cheers,Adam
Hi,We have a heavily used production server and a table which logs everyhit on a web site. This table has grown large over time and we want toclear it down as efficiently as possible. We would like to issue atruncate table statement, but with millions of rows we are a bit waryof how this will affect server performance. The alternative is todelete is stages using rowcount but of course this will generate alarge amount of logging.Can anyone confirm whether issuing a truncate table will have anyaffect on performance - i.e. does it just clear a header block ordooes it have to do more?CheersMartin
