Difference Between Truncate And Delete

SQL Server 2012 :: Behavioral Difference Between DELETE And TRUNCATE

I have an issue with Delete statement.In the code given below (its a part of actual proc),if we use TRUNCATE to clean the temp tables, everything goes fine.But if I use DELETE in place of truncate, system skips the IF loop 'if (@script_type = 1 OR @script_type = 2)'I am not able to understand this behavioral difference between DELETE and TRUNCATE.Recently the database is being used for replication, but that should not be a reason.

SELECT @max_rows = COUNT('X') FROM #temp_table1
SET@row_cnt = 1
WHILE @row_cnt <= @max_rows

Truncate Or Delete With CONSTRAINTS

Hi all
i have a problem.
i have this method


protected void DeleteDataFirstAccess()

{

SqlCommand cmd = new SqlCommand();

cmd.Connection = conn;

cmd.CommandText = "select name from sys.all_objects where type='U'";

DataTable table = DataBase.GetDatatable(cmd); //this is one of my method wich return a datatable with data

foreach (DataRow row in table.Rows)

{

SqlCommand cmd_delete = new SqlCommand();

cmd_delete.CommandText = "TRUNCATE TABLE " + row[0].ToString();

cmd_delete.Connection = conn;

cmd_delete.ExecuteNonQuery();

cmd_delete.Dispose();

}

cmd.Dispose();

}

when i run i have an error with some tables constraints.
As you know If we try to TRUNCATE a table, and the table is have a relationship with other table like for exemple Employees_Salary with the constraint of SQL Foreign Key then we can't TRUNCATE the table with SQL Truncate Table command, we need to TRUNCATE the Employees_Salary table first because Employees_Salary is depending on it and that is having some records. That's why we need to TRUNCATE both tables and the sequence is to empty that table which is based on SQL Foreign Key or remove this constraint first.

What i need is a list of all database tables ordered by the right sequence considering the constraints
Anyone can help me?

thanks in advance
bye

How To Find Who Delete / Truncate Data From Table

how to find who delete/Truncate the data from table ,because i don't have any trigger on the table.

Delete/truncate Table Ignoring Contraints

Is there any easy way to truncate a table which has a foreign key restraint? I want to override the default behavior which is to not allow truncate of parent tables. I want to be able to temperarily remove the contraint so I can truncate the temple, how do you do this?

Integration Services :: Truncate Or Delete Access Table Using SSIS?

I have to truncate  access table before I insert records to access database table. 

I tried using Delete From Table_name  or Truncate table Table_NAME and I have used Microsoft Jet 4.0 OLE DB Provider. It does not seem to work. I read some post on forums. None of them seem to work while truncating or deleting records from one of the access database table.

Is there any easy way to truncate access database without using script component and VB scripts. I do not know how to Write VB scripts so trying to find alternatives.

What Is Difference Between Delete And Trunket?

What Is Difference Between Trunctate And Delete ?

Both delete the data like rows, columns, or table ?
Delete can have Log file, can roll back, also it is DML demand /
while Truncate delete the records from log file, can release Memory space, it's DDL statement.

'Truncate' Command Doesn't Truncate Enough

With a database size of almost 2 GB, I run the 'truncate table eventlog command' which completes successfully, but the database size only decreases by about 10 MB so stays too large - indeed the number of rows in the eventlog table is minimal, but the otehr tables in this database don't show such an amount of tables large enough to cause the size issue either. What could be the reason and how can I reduce it (possibly truncating another table but then which one, how could I determine which is too large and needs truncating?).

Can Anyone Give Me A Layman's Explanation Of The Difference Between CURRENT_TIMESTAMP And GETDATE() (if There Is A Difference)?

Question is in the subject.

To Truncate Or Not To Truncate: That Is The Question..

Hi all...

Please forgive the elementary nature of my question, but could someone please explain the differences between these two database backup types:

1. Log backup
2. Log backup no truncate



From what I understand and have read, the "no truncate" backup method keeps the entire transaction log indefinitely. Using the truncation method, the transaction log is either 1) compressed or 2) cleaned up so that any completed transactions are removed from the log. Which one of these is true?


And, for the big question: is it better to run a backup of the transaction log with truncation or not? Our current backup scheme is similar to the following:


Full backup every 24 hours
transaction log backup every hour with no truncation


Should we insert a truncation backup somewhere in here? What is the danger of removing (or compressing) parts of the transaction log? Will this affect the restore process?


Thanks in advance!

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

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

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?

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!

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

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

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

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. I have an admin page where I can select a user and delete all of his messages just by clicking one button.What would be the best (and easiest) way to make this?Here's my suggestion:I have made a "delete query" (with userID as parameter) in MS Access. It deletes all messages of a user when I type in the userID and click ok.Would it be possible to do this on my ASP.net page? If yes, what would the script look like?(yes, it is a newbie question) 

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
AS

[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

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.

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

Truncate Log

I would like to ask if I backuped the transaction log already, SQL will truncate the transaction log automatically or not. If not what should I do?

Truncate Log

Is there an ISQL statement to truncate the transaction log??? A Stored Procedure maybe?

SQL CE 200 And TRUNCATE

I have two tables in my SQL CE database. tblTempData and tblBatchData. When the user wants to move the data from 'temp' into 'batch' I would like to truncate the 'temp' table. When I do this I get the unable to parse query error.

strSQL = "TRUNCATE TABLE tblTempData"
goADOcn.Execute (strSQL)

Is there something that I am doing wrong, or is TRUNCATE not supported in SQLCE 2000?

Truncate?

can TRuncate statement be rolled back ?

Truncate Log

Hi there,

I have a simple stored procedure that will truncate the log file but I now need to make this dynamic so that this proc can be run with any DB name. I know you can look up the logical filename in sysfiles but I'm not too sure how to write this procedure so that it will simply truncate the log file of the currently selected DB.

This is what I have so far which as you can see is hardcoded:

SET QUOTED_IDENTIFIER ON
GO
SET ANSI_NULLS OFF
GO


CREATE PROCEDURE TruncateLog AS

BACKUP LOG [FICaches] with TRUNCATE_ONLY


DBCC SHRINKFILE (FICaches_log, 50)


GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO

Any help would be greatly appreciated!

Thanks

Truncate Log

Hi

I have a Log which is 15 gb. Recovery mode is simple.

What command can I use to truncate this log? Or is it best to shrink it?

Thanks

Truncate

I have a small doubt .
Truncate is not a logged operation.
In log shipping if we perform any truncate operation on the primary server will its get reflected on the secondary server.

Truncate

I have 2 tables.
Table 1 and table 2.
Table 1 has a foreign key related to a particular column on table 2.
Suppose if i have applied a truncate command on table 2 .will it work or not.
We have to check for dependencies on the table before we should apply a truncate command.

Could any one tell me can we directly apply a truncate command on any object irrespective of the dependencies on that object.
