Data factory truncate table

I'm copying data from table storage to a sql azure database. Im using ADF. Im able to setup the process. I want to schedule a recurring meeting and add a truncate table. How do you delete all records in the sql azure database?

Hi Julius,
You could use a Stored Procedure to handle the delete and insert, in the Sink (Destination) side of the Copy Activity.
Borrowing from another recent reply:
You can specify the property "SqlWriterStoredProcedureName" and "SqlWriterTableType" in SqlSink, and add the merge logic in your own stored procedure. Notice that don't use a simple delete operation in the stored procedure, as it may
be called several times in a single Copy.
For more information about how to use this feature, refer to this post.
and the Azure documentation here http://azure.microsoft.com/en-us/documentation/articles/data-factory-copy-activity-advanced/

Imp into Dev from Prod - schemas, data only, truncate tables

Hello,
I am going to impdp from Prod to Dev. This is a data only import. I plan to do a schema impdp. This is the command I plan to use:
impdp system/password schemas=user1,user2,user3,user4 directory=dir_123
logfile=imp123.log dumpfile=dump123.dmp content=data_only table_exists_action=truncate
1) Do I need to disable the contraints/triggers in Dev before doing impdp?
Is disabling contraints necessary in Dev since the contraints in Prod have no violations?
2) What is going to happen if in Dev the objects already exist? For example, an index on a table, would this index be over written during the impdp? Or do I drop the index in Dev prior to the import and then let the import create new ones?
3) What impdp options should I use, if I only want to truncate the tables belonging to the schemas being imported? What about existing objects, such as indexes, what is going to happen to the existing objects? Are they going to be over-written by the impdp?

Recovering Data from a truncated table in OraXE?

A funny thing happened, i truncated a table containing BLOBs and other stuff, with over 700 entries!!, now i wanna know if it´s feasible to recover that truncated data, i'm just wondering about it, i know it sounds silly i know, but the storage space didn´t get shorter after the data was truncated from the table, so after this´s been said, can any body explain me what happened, can i retrieved this truncated data that i truncated from the table (without any previous backup)?

Truncate simply resets the pointer that marks the 'end of data' in a table to the beginning of the table. The storage is still allocated, on the assumption that you want to reuse the table and want to avoid the overhead associated with extending the table. The system knows there are never any rows past the 'end of data' and it won;t bother looking past that point.
Recovering that data from the actual current database - about as likely as recovering data from the Windows recycle bin when you've set the max allowable storage in the recycle bin to '0'. Technically possible, but needing someone with a lot of experience and patience ... and absolutely no changes to the database after truncate. An expensive proposition.
You have, of course, switched to archive log mode and been taking regular backups. (Have you not?) In which case, a 'point in time' recover, to just before the truncate, would be the solution. This brings back the database (or at least a tablespace) back to a former 'life', and is quite different from restoring a table.

How to update date in a table from another database

Hello,
I am trying to code a way to Update my Testing database from another database. In the coding below the database that has the updated data ends in Restore.
Use ClientDB_MASTER_Restore
Truncate Table ClientDB_MASTER_Testing.dbo.Activity_Tracking_AZ
GO
SELECT * INTO ClientDB_Master_Testing.dbo.Activity_Tracking_AZ
FROM Activity_Tracking_AZ
Go
I know with this Technique the table must be truncated if not deleted first. There is probably a better way to do this which I'm very open to. I'm also looking for coding that will roll back any changes made should an error occur.
As always, any help is greatly appreciated.
David92595

USE ClientDB_MASTER_Testing
go
SET XACT_ABORT ON
BEGIN TRANSACTION
Truncate Table dbo.Activity_Tracking_AZ
-- SET IDENTITY_INSERT dbo.Activity_Tracking_AZ ON
INSERT dbo.Activity_Tracking_AZ (col1, col2, ...)
SELECT col1, col2,
FROM ClientDB_MASTER_Restore.dbo.Activity_Tracking_AZ
-- SET IDENTITY_INSERT dbo.Activity_Tracking_AZ OFF
COMMIT TRANSACTION
If you find it boring to type the column lists, just find the table in Object Explorer, and drag the columns node to where you want the column list.
You need the SET IDENTITY_INSERT command if the table has an IDENTITY column.
By wrapping the code in a transaction, you are not left with an empty table if the INSERT fails. The command SET XACT_ABORT ON makes sure that the batch is aborted and rolled back in case of an error.

How to delete all data in a table

What's the best way to delete all of the data from a table? I wan't to do a data wipe of our database to eliminate all of the test data we've been putting into it over the last few months.
I've tried using: DELETE FROM TABLENAME; but killed SQL+ after it ran for 13 hours and still wasn't done. There are approximately 900,000 records in this table and I would prefer not to drop/recreate the table because of the various dependencies within the database.
Any suggestions would be appreciated.
Thanks,

Try the TRUNCATE TABLE command. That's quick and easy.
e.g.
TRUNCATE TABLE mytable;

How to delete some date in target table at a mapping?

How to delete some date in target table at a mapping?
I extract date from source tabel into target table,
but before extract date I want to delete some date from target?
how to do?

Just to change a bit of terminology in the reply, within the mapping, click on operator properties and choose TRUNCATE/INSERT.
Note that truncate is dependent on constraints, so you probably must disable those before doing this. You can of course do DELETE/INSERT...

Copy data from one Table to another Table

How can I copy data from one Oracle Table to another Oracle Table on a different server? Question 2: How can I clear all of the data in one Table with a single SQL script?
Thanks...

Question 1:
I assume you have the privileges. If you don't, ask the DBA to give them to you. Then
1. Login to database_source (It could be either the source or the target. Let's assume it's the source.)
2. Create a database link to database_target: CREATE DATABASE LINK link_to_database_target CONNECT TO myuserid IDENTIFIED BY mypassword USING 'database_target'; Note the single quotes.
3. Copy the table data: INSERT INTO targetowner.mytable@link_to_database_target SELECT * FROM sourceowner.mytable; COMMIT;
Question 2:
You have two options, but you may not have privileges for both.
Option 1:
DELETE FROM tableowner.tablename; COMMIT;
Advantage: Since this is a DML (Data Manipulation Language) statement, you have to commit the transaction. Also, the data will be gone but the table size is NOT changed, so it's ready for accepting replacement data. DML statements can simply be executed not only from SQL scripts, but from PL/SQL scripts as well.
Disadvantage: Slow, because all record deletion is logged, so you can recover from it by issuing a ROLLBACK; instead of the COMMIT; above. The table size is NOT changed, so if you are short of disk space or tablespace space, you have not resolved the issue.
Option 2:
TRUNCATE TABLE tableowner.tablename;
Advantage: Since this is a DDL (Data Definition Language) command, you do NOT have to commit the transaction. (DDL commands automatically commit both before and after their execution.) The table size will be changed back to the initial extent size which is the minimum size a table can have and can only be set when the table is created. If it needs to be changed, the table has to be dropped and recreated with a different initial extent size. The statement execution of this command is not logged, therefore it's much faster then the DELETE.
Disadvantage: No rollback. Being a DDL, this command cannot be executed straight from PL/SQL. If you need to issue this within PL/SQL, you will have to use dynamic SQL.

When there are multiple tables in a control file, SQL Loader assumes the data for the first file in the second table immediately follows the last field in the first table. You probably want SQL Loader to start looking for the first column of the second table at the start of the second table. You can do this by using the POSITION clause

Truncate Table before Insert--Performance

HI All,
This post is in focus of special requirement where a table is truncated before inserting records in the table.
Now, when a table is truncated the High Water Mark(HWK) is reset to lowest memory allocated for table in tablespace. After this, would insert with append can boost the performance of the insert query?
In simple insert query, the oracle engine consults the free list to look for free spaces.
But in insert with apppend, the engine starts above the HWM. And the argument is when truncate has been executes on table, would the freelist be used in simple insert.
I just need to know if there are any benefits of using append insert on truncated table or simple insert would be same in term of performance with respect to insert with append.
Regards
Nits

Hi,
if you don't need the data truncate the table. There is no negativ impact whether you are using an conventional path or a direct path insert.
If you use append less redo is written for the table if the table is in NOLOGGING mode, but redo is written for all indexes. I would recommand to create a full backup after that (if needed), because your table will not be recoverable after that (no REDO Information).

Using SSIS Script task to populate data from one table to another

I have two tables Table A and Table B. Need to insert data into Table B from Table A. First, I truncate Table B and then insert. Few columns in Table A and Table are similar. However, I need to join with
other tables Table C, Table D etc with Table B in order to populate the columns in Table B. Could someone please provide the code snippet to achieve this.

Appreciate your quick response Prasad. Below is the code I'm using to achieve.
Public Sub Main()
Dim connEOCDB As SqlClient.SqlConnection = GetDBProdConnection(Me)
Dim trans As SqlClient.SqlTransaction = connEOCDB.BeginTransaction()
Try
Dim TableA As New DataTable
Dim TableB As New DataTable
Dim DataadapterTableA As New SqlClient.SqlDataAdapter()
DataadapterTableA.SelectCommand = New SqlClient.SqlCommand("select * from TableA", connEOCDB, trans)
DataadapterTableA.Fill(TableA)
Dim DataAdapterTableB As New SqlClient.SqlDataAdapter()
DataAdapterTableB.DeleteCommand = New SqlClient.SqlCommand("Truncate table dbo.TableB", connEOCDB, trans)
DataAdapterEmpExtdT.InsertCommand = New SqlClient.SqlCommand("insert into dbo.TableB (Col1,Col2,Col3,.....) values (@Col1,@Col2,@Col3...)", connEOCDB, trans)
Could you please let me know how I can assign values to @Col1, @Col2 etc from
DataadapterTableA.Fill(TableA). Also, as mentioned earlier, I need to use joins to populate @Col3 etc as well.
Please advise.

Truncate table loses privs on table...

Oracle11g/RHEL5
Hi,
We have a table that is inserted into a then deleted every so often. The current method that was being used to remove the rows was the TRUNCATE TABLE ption. However, we found out that when that statement is issued, that any user that had privs on that table, no longer work even after it is re-created. So it looks like the next option is to used the DELETE * from table_name. However, that is not good for performance and undo. This table is about 300,000 rows and will grow in the future. How could we get around this issue?
Thanks.

TRUNCATE TABLE does change privileges.
What do you mean by "after it is re-created"? You don't have to issue another CREATE statement after TRUNCATE TABLE.
Do you mean after re-populating the table? Do you mean that other users, who did have privileges, can still DESCRIBE the table right after it is TRUNCATEd, but they can't do anything with it after an INSERTs have been done?
I suspect you DROPped the table at some point.
Double-check that the problem exists when all you do is TRUNCATE TABLE.
Post a script that re-creates the problem. There's no need to include lots of data: one column and one row will show the problem just fine.

Truncate table related questions

Hi Folks,
Environment: 10g Rel 2
I am trying to prove the following two points by way of experimentation
a, The truncate table operation will reset the high water mark (HWM) to the first usable data block in the table segment
# Take a HWM snap shot before the truncate operation
select a.BLOCKS - b.EMPTY_BLOCKS -1 HWM
from
(SELECT BLOCKS
   FROM   DBA_SEGMENTS
   WHERE OWNER=UPPER('JIM') AND SEGMENT_NAME = UPPER('EMPLOYEES')) a,
   (SELECT EMPTY_BLOCKS
    FROM   DBA_TABLES
    WHERE OWNER=UPPER('JIM') AND TABLE_NAME = UPPER('EMPLOYEES')) b;Output: 7
truncate table JIM.EMPLOYEES;
Re ran the above code and got the same result (i.e. 7 blocks). I was expecting to see 0 blocks instead? Is the above query the right method of
finding the HWM?
b, The truncate operation will also truncate the corresponding indexes for the table
Q, Is there a view that will show all the index values of the table? These values will probably be meaningless, but I would like to see them before
and after the truncate operation.
Thanks
rogers42

a) If you would have read on the empty_blocks column in dba_tables, you would have known it is populated by dbms_stats.
Did you run dbms_stats.analyze_table?
b)
There is no such view.
All dictionary views are documented in the view DICT and the online documentation.

Truncate Table

Folks,
I am creating an application for users to enter various parameters to be used in generating a mass of reports. This is replacing an existing MS Access application that has an option to truncate the entire table's contents.
How do I invoke a simple truncate table function rather than require the user to individually delete hundreds of rows of data?
Thanks. Bruce

Bruce,
How about a PL/SQL page process with code like this, assuming the table name will have to be derived or constructed for individual users: declare q varchar2(30);
begin
q := 'BASE_NAME_'||:APP_USER; -- example
execute immediate 'truncate table '||q;
end;Scott
