Copying Tables And Generating New Keys
May 23, 2007
I have a large table that I need to copy, but I need to generate a new value for my id field using a SPROC and replace my existing ID value. I also have a few mapping tables I need to copy, so I need to store this new ID for later use. I currently have a SPROC that performs all these actions, but it takes about 3 or 4 minutes to complete and completely hogs the CPU time. Thus, I can't perform any actions until it finishes.
I'm looking for a way to run this procedure in the background. Unfortunately, my ID field value is not a GUID nor an IDENTITY column. I've researched Integration Services, but I was unable to find any DataFlow Tranformations to call a SPROC to retreive a new id nor could I find anything that would let me store my new id to update my mapping tables. SQLBulkCopy wasn't a good solution either.
If anyone has any insight to this, it would be greatly appreciated. Thanks,

This might be tricky, but I wanted to know if I can add a row to the table and decide wht keys I want to generate for that row.
For example: I have a table which have 4 different keys. I want to generate only 2 of them for certain rows and all for the remaining rows. Is this possible? This does sound like an advanced feature for sql databases, but its easy to do with custom dbs like berkeley db
Trust me, its a very helpful feature.
Thanx in advance,
Premal

what the best practice is for creating indexes on columns that are foreign keys to the primary keys of other tables. For example:
[Schools] [Students]
---------------- -----------------
| SchoolId PK|<-. | StudentId PK|
| SchoolName | '--| SchoolId |
---------------- | StudentName |
-----------------
The foreign key above is as:
ALTER TABLE [Students] WITH CHECK ADD CONSTRAINT [FK_Students_Schools]
FOREIGN KEY([SchoolId]) REFERENCES [Schools] ([SchoolId])
What kind of index would ensure best performance for INSERTs/UPDATEs, so that SQL Server can most efficiently check the FK constraints? Would it be simply:
CREATE INDEX IX_Students_SchlId ON Students (SchoolId)
Or
CREATE INDEX IX_Students_SchlId ON Students (SchoolId, StudentId)
In other words, what's best practice for adding an index which best supports a Foreign Key constraint?

Like a back-uputility.Can anyone recommend one (or tell me which ones to avoid)? Iwould like one that takes dependencies between tables intoconsideration.Thanks

hi, I'm using sql server 2005 standard, and I want to be able to move my local database to another server, but I can't figure out how to script the database and the data so that I can just run one script to move the whole database. this can be done right? I can't imagine that such an obiviously necessary tool would be intentionally left out, so I'm figuring that I'm just a doofus and don't know where the option is...
can anyone help? thank you!

Hi,
I have a little question. I searched google, and could not find good answer for this one.
I have a stored procedure that returns two tables. Usually I generate a dataset out of a stored procedure by dragging it to the dataset.
When I drag this one it creates a DS with only one table, the first one. How can I make it use both tables?
Thank you.

Hi...
I'm trying to generate scripts in SQL Server Management Studio 2005.
When I choose 'Script all objects' I get an error when I try to execute it. When I generate the scripts in single files, only tables in one file, only views in one file etc. etc., the execution is succeded.
1) Why do I get an error when I try to execute the script containing tables, views, procedures in one file....?
2) I get an error in the view-file where one column is 'invalid' but I can see it in the view. A generated script should execute succesfully when it is generated one second ago on the same database and so on... Right?
Thanks....

hi.
How to update FormA table from customer table. Let say i wish to keep small number of fields from each table so i use foreign keys as reference.
However i had a problem when i tried to save the relationships of both tables, i receive the error that FormA_id is not able to insert null into value.
Cust_id(PK) is identify column, as well FormA_id(FK) and FormA_id(PK) too. For example, when i insert a record from customer table, it will automatically create id for FormA.
Table structure. Customer
cust_id(PK),name,age,formA_id(FK)
Table structure, FormA
formA_id(PK), info, date,
How to solve ?

Is there any simple way to copy tables from one database to another in SQL Management Studio or VS 2005? I sometimes work split work between home and work and I often need to copy and table and its data (data, stored procedure, etc) to a different database, but having to create a new database then copy the data is a pain. Is there an easier way?

I have a 100m row table that I need to come from one database to another database in SQL SERVER.
The bulkcopy feature in DTS is nice -- however is there a stored procedure or external software that will be able to do this outside of DTS.
Right now I am doing a
SELECT *
INTO
(table name)
FROM (table name)
and on a 100m row table it is taking around 52 hours. Not acceptable.

Other than right-clicking on each individual table in SSMS and generating a CREATE script, is there a simple way to generate CREATE TABLE scripts for tables within a given database?
Background: I have a bunch of tables in one database, and I would like to add tables to a second database that have the same names and basic structures of some of the tables from the first database.
I do not need to transfer any data from the tables, this is a seperate project that will use a similar data structure. I just want to generate the CREATE TABLE scripts for 30ish tables within the first database, and then I'll tweak the scripts as appropriate and run them against the new database.

I have a setup with a bridge table. There are about 5 different tables
on one side of the bridge (all with compatable PK columns) one of which
is called 'mobilesub', and one on the other side called
'allcostcenters'. The bridge table is called 'subaccountcostcenter'.
I can enter data for mobilesub in the bridge table. But then when I try
to enter the info into the bridge table for any of the other tables,
such as localsub, there is a conflict like this:
INSERT statement conflicted with TABLE FOREIGN KEY constraint
'FK_subaccountcostcenter_mobilesub'. The conflict occurred in database
'test1', table 'mobilesub'.
The statement has been terminated.
Is there some rule against using a bridge table that references several
different tables, and I'm just not aware of it. Because I've done
everything I can to make sure the info from the different tables don't
conflict . . .
The same error comes up if I do the localsub table first--in that case
the foriegn key messing me up is FK_subaccountcostcenter_localsub. So
it's not something with the individual tables.
I need experienced advice lol
Thanks

Does anyone have a script that will roll through the tables in a database and identify tables without primary keys defined? I did not see any in the online script database.

I know altering the schema of system tables is a big no-no, but I was wondering if setting up a table that has foreign keys pointing to a system table is bad.
Basically what I'm refering to is in some cases I have CreationDate and CreatedBy fields in my tables that correspond to GETDATE() and USER_NAME() functions in insert statements....I want the CreatedBy field to be a valid SQL server DB username ... and not some unchecked string value (SYSNAME actually)

Hello,We imported a bunch of tables from a database and realized that theprimary keys weren't copied to the destination db. In order to re-create the keys, we need to know which tables have them. Is there acommand that I can use (on the source db) to find out which tablescontain primary keys? The db has hundreds of tables and I'd rather notgo through each one to see which has a primary key.Also, for future reference, is there a way to include the primary keyon an import?Thanks,Peps

I've created a table called Employees with a primary key called EmployeeID. The table contains EmployeeID, FirstName and LastName columns. I now want to create a table called Team which will contain the columns TeamID, EmployeeID (to reference the column EmployeeID from the Employee table) and a column called TeamName. Sql won't let me create multiple primary keys in one table (I did think that was the case ) key but yet if I look at the Adventure Works database in the Person.PersonPhone table, I can see three primary keys defined.

I am trying to write triggers on each tables in my database to audit data changes. My AuditLog table consists of the following columns -
LoginName varchar(100) - user name
Action varchar(5) - this will store 'INSERT','UPDATE','DELETE'
TableName varchar(30) - name of the table updated
PrimaryKey int - primary key of the record updated
ColumnName varchar(30) - name of the column updated
OldValue varchar(1000) - old value converted to varchar
NewValue varchar(1000) - new value converted to varchar
RecUpdDate datetime - record update date.
This table design will work for tables with single column primary keys. However, it will not work for tables with composite primary keys. Any suggestions on how to make this work with composite primary keys? I prefer not to change the tables in my database to use single column primary key.
Thanks in advance.

We've had a new server set up with SQL 2012 and I'm in the process of moving data to it from a 2008 (SP2) server.
Details are as follows:-
2012 instance:- Microsoft SQL Server 2012 - 11.0.5058.0 (X64)
May 14 2014 18:34:29
Copyright (c) Microsoft Corporation
Standard Edition (64-bit) on Windows NT 6.3 <X64> (Build 9600: ) (Hypervisor)
2008 instance:- Microsoft SQL Server 2008 (SP2) - 10.0.4000.0 (X64)

I don't want to do a backup/restore routine as there are collation conflicts on the 2008 server.I've created the database and tables on the 2012 instance and now I want to transfer the data from the 2008 instance to the 2012 one.
The 2012 instance has a linked server to the 2008 instance.I was trying to use sp_MSForEachTable (I know, it's old and will probably disappear shortly) but that doesn't seem to work properly because some of the columns have an Identity field set up.
Some of the tables have upwards of 10 million records in them and are quite sizeable.how I can achieve the transfer without a back-up/restore?

HI,
I current have two 2005 boxes running 9.0.3050 in different DMZ with the source running a DTS to drop and copy its tables to the source every night. It was working up until last thursday. Nothing has changed in the FW rules and getting no errors. One is 3.5GB which copies fine, the other is 21GB and runs all night with only getting a fraction of the tables populated. I'm the hardware guy, but have some understanding w/ sql. Thanks in advance for any help.

Hi. I need to move data from one database table to
another across database instances. A simple example of the typical
move would be:
[CODE]
INSERT into destination_db.dbo.table1
SELECT column1, column2, column3, column4 from source_db.dbo.table2
[/CODE]
My options are:
1. Create an SSIS package to perform the move.
2. Create sprocs and schedule the data move as jobs.
3. Write .NET code using sprocs to perform the move.
I'll have to move hundreds of thousands of records, so I want the
option that provides the best performance. I'm guessing that option 3
will be the slowest.
Thanks for the help!

I need to create a fairly simple package. And almost because of the simplicity, I'm stumped.
I need to copy all non-system tables from server1.database1 to server2.database2. Additionally, four of the 30+ tables need to be renamed on the fly -- i.e. their name will reflect the year and month that the copy takes place.
I've tried using the Transfer SQL Server Object Task to simply copy the tables, but I get flaky results at best with it. Sometimes it tells me the source table doesn't exist, when I can clearly see it (and I've selected it from the list). And even though I have turned on the Include Indexes option, they don't always come through.
I'm wondering if I need to do a For Each loop looking at an ADO object?
Any suggestions?

Hi,
I'm trying to create a package with SSIS to replace the DTS process that we have in place already.
DTS package copy four table content from one server to another. I have created a simple SSIS to do the same processes but the process it alot slower than DTS!!
I did ran the SSIS package using ctrl+F5 and also from command prompt but still it's quite slow.
SSIS uses SMO to access to server and both are running on 2005
Thanks

I have a situation that I must resolve. I have a program being used by many but I had to create a new table to provide a new feature. The problem I have is this table must use the primary key from the parent table as its primary key, meaning when a user adds a new record to parent table, I need to instantly add the primary key to the child table. Now this was done in the program using sql statements, but I need to implement a trigger or such as to keep me from having to reinstall application on many computers.
basically person inserts new record, then I need to get the new primary ket and add insert it into the child tables. how can I do this with a trigger. I have tried to use an insert into statment with my trigger, but I can't seem to pass the parameters correctly.
CREATE Trigger dbo.Table_Borrower_Insert_Keys
ON Table_Borrower
AFTER INSERT
AS
begin
declare @bid as int
@bid = select MAX(BorrowerID)
FROM Table_SoldProgression
INSERT Table_SoldProgression(BorrowerID)
values (@bid)
end
GO
another attempt
CREATE Trigger dbo.Table_Borrower_Insert_Keys
ON Table_Borrower
AFTER INSERT
AS
INSERT Table_SoldProgression(BorrowerID)
values (select MAX(BorrowerID)FROM Table_Borrower)
GO
