I want to get rid of a huge table. DELETE FROM would take for-freaking-ever, so I was thinking of doing DROP TABLE. Would this be any faster?
If not, would doing a TRUNCATE TABLE and then DROP TABLE be fast? What's the best way to nuke a big table?
Thanks.
which one is smarter, where there is no indexing on the table which is really simple table delete everything or recreate table. I got an argument with one of my coworker. He says it doesnt matter i say do delete. Any opinions.

hello,
im creating a sp that creates a view from a query then bcp to csv file.
my problem is that when i start the sp, it complains the sp already exists....yes it does, however, i don't if im going about this the wrong way...but i tried the following to no avail
DROP IF EXISTS v_participantTrades
now, does that syntax not work for views?
We have a secuiry review and they have recommended dropping several xp_ stored procedures. I have tried the drop procedure with no luck, Error 3701, or right click delete in Man Studio, same error. I have granted the user alter permission to the master database and when I try to delete get Error 4606. I try to grant CONTROL permission of the stored proc to the user and get another 4606 error.
Do I just have to control the permissions of these procedures tightly?
Thanks In Advance

Hi seniors
there are two tables involve in replication let say table1 and replicated table is also rep.table1.
we are not deleting records physically in table1 so only a bit in table1 has true when u want to delete a record but the strange thing is that replication agaent report that this is hard delete operation on table1 so download and report hard delete operation and delete the record in replicated table which is very crucial.
plz let me know where am i wrong and how i put it into right way.
there is no triggers on published tables and noother trigger is created on published table.

I am new to mssql server. There is a table on one of my databases that occupies a lot of space. And the space usage is as follows: (all values in KB)
reserved: 42329064
data: 16272288
index: 26050032
unused: 6744
This table takes up almost 80% of my database size, and the information is this table just captures the time spent by a user on the website(not very critical data)
I would like to know how to delete the entire index (which is what is occupying most space) to free up disk space. the index is a clustered index.
How to delete/drop all the tables from SQL Server Database without using Enterprise Manager?
I tried using DROP Tables, Truncate Database, Delete and many more but it is not working. I want to delete all tables using Query Analyzer, i.e. through SQL Query.Please help me out in this concern.Nishith Shah
Hi,
I have been working around with SQL Server Express 2005 on VISTA. I created a small C++2008 application which interface with SSE 2005. When running my application, it automatically created a user instance which I would like to get rid of. I just forgot from start to set "User Instance = False" in my connectionstring. (oups...)
I'm aware, from readings I did, that a couple of tables as well as log files, etc. are created under directory "utilisateurs...AppDataLocalMicrosoftMicrosoft SQL Server DataSQLEXPRESS". SQLEXPRESS is the instance name chosen during install of SSE2005.
Also using following SQL Statement:
select owning_principal_name, instance_pipe_name, heart_beat
from sys.dm_os_child_instances
I got following result:
owning_principal_name: PC-DE-STEPHANEStéphane
instance_pipe_name: \.pipe6172F4E8-622E-4A sqlquery
heart_beat: dead (at this moment...)
==> How can I make a good cleanup of all this as well as get rid of the user instance itself?
Thanks in advance for any help.

For reasons that are not relevant (though I explain them below *), Iwant, for all my users whatever privelige level, an SP which createsand inserts into a temporary table and then another SP which reads anddrops the same temporary table.My users are not able to create dbo tables (eg dbo.tblTest), but arepermitted to create tables under their own user (eg MyUser.tblTest). Ihave found that I can achieve my aim by using code like this . . .SET @SQL = 'CREATE TABLE ' + @MyUserName + '.' + 'tblTest(tstIDDATETIME)'EXEC (@SQL)SET @SQL = 'INSERT INTO ' + @MyUserName + '.' + 'tblTest(tstID) VALUES(GETDATE())'EXEC (@SQL)This becomes exceptionally cumbersome for the complex INSERT & SELECTcode. I'm looking for a simpler way.Simplified down, I am looking for something like this . . .CREATE PROCEDURE dbo.TestInsert ASCREATE TABLE tblTest(tstID DATETIME)INSERT INTO tblTest(tstID) VALUES(GETDATE())GOCREATE PROCEDURE dbo.TestSelect ASSELECT * FROM tblTestDROP TABLE tblTestIn the above example, if the SPs are owned by dbo (as above), CREATETABLE & DROP TABLE use MyUser.tblTest while INSERT & SELECT usedbo.tblTest.If the SPs are owned by the user (eg MyUser.TestInsert), it workscorrectly (MyUser.tblTest is used throughout) but I would have to havea pair of SPs for each user.* I have MS Access ADP front end linked to a SQL Server database. Forreports with complex datasets, it times out. Therefore it suit mypurposes to create a temporary table first and then to open the reportbased on that temporary table.
View 6 Replies View RelatedHello:
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!

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
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.
'****************************************************************************
Cmd.CommandText = "Drop Table Raj"
Cmd.ExecuteNonQuery()
Cmd.CommandText = "Select * Into Raj From XXX"
Cmd.ExecuteNonQuery()
'**************************************************************************
This generates error that Table already exist.
If Wait 1 sec then execute statement then it works fine.
Thanks in Advance

Hello !
I try to drop a table, but I get this message :
Could not drop object 'dbo.cs_Users' because it is referenced by a FOREIGN KEY constraint
This message does not tell me which is the Foreign key constraint so that I may disable it.
Any solution to force the dropping?
Thank you very much!

hi, is it possible to recover the dropped table?
if means please tell me how.
hi everyone,
I have a couple questions. I'm very new to SQL and I have this problem:
I need to be able to drop the contents of Existingtable_B into Newtable_A - I found this command (below) that will make a 'copy' but I don't want to keep the contents of Existingtable_B. Is it possible to drop them into Newtable_A instead of copy? Also, I want to do this for 5 tables on Sundays at midnight.. how could I schedule that? Finally, what happens if there is not enough space or some other critical error happens during this procedure? I don't want to lose the data.
Any help is greatly appreciated.

I need some help with Merge Replication. After successfully defining a publisher, distributor and subscriber to perform merge replication, we decided to test Merge Replication to see what we can and can't do.
What we found is that you can't add new fields or change the nullable/null attributes of tables whilst the replication settings are still defined to the databases. ie you get the following error
'tblProducts' table
- Unable to modify table.
ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot drop the table 'dbo.tblProducts' because it is published for replication.
So we thought, fair enough. We decided to uninstall replication using the wizards provided to see whether we can make schema changes. What we found is that we can make schema changes to the publisher database(on Server1), BUT not to the subscriber (Server2).
Does anyone know why? We are running SQL7 SP2.

We have a table created by an application, and a view that joins the table with other tables.
For some reason we are now unable to drop the table or the view. In Enterprise Manager the drop table dialog comes up, we click 'Drop All' and then the hour glass comes up and never goes away. No errors are returned, the process just never returns control to the client, the same when trying to remove the view. Using Query Analyzer is no different.
However stopping and starting the server resolves the problem for a while, but eventually the same problem starts happening. The table is created, populated and dropped using stored procedures called from a web page via asp script. This process may occur numerous times and hasn't been a problem until the last day or so when the developer added a couple of smallint columns to the table.
Anyone know what could be the problem here?

Hi,
I had a question and did not obtain an answer. So I am trying to rephrase and ask again, in case I was not clear the first time.
When we drop and recreate a table, do we always have to recompile the stored procedures that reference the table? Or is only under certain scenarios that we need to do so- like if an index on the table is changed
Please let me know
Thanks in advance

I have a group that has select, insert, update, delete permissions and I have a user in that group that
needs permissions also to drop tables.
does that login need to be aliased to dbo - which is in public -- do I then to give puboic all the other permissions.
Is there a way to just give one login all permissions including dropping tables??
