SQL Server 2008 :: When Renaming A Table / It Doesn't Rename Foreign Key Constraints
Sep 21, 2015
I'm working on creating a new version of an existing table. I want to keep the old table around, only with a different name. In looking this up I found there's a system routine named sp_rename, which looks like it will work fine.However in thinking about this I realized that the foreign key constraints defined on the table (there's 3 of them) are likely to not be renamed, correct?
If I'm correct, then I suppose I could rename the table, then drop the 3 foreign key constraints, and create them new using different names for those foreign key constraints.

I'm inserting from TempAccrual to VacationAccrual . It works nicely, however if I run this script again it will insert the same values again in VacationAccrual. How do I block that? IF there is a small change in one of the column in TempAccrual then allow insert. Here is my query
INSERT INTO vacationaccrual
(empno,
accrued_vacation,
accrued_sick_effective_date,
accrued_sick,
import_date)
[Code] ....

I know this is probably a flick of a switch but I cannot figure out which switch. Setup is SQL Server / Stored Procedures / DAL / BLL(skipped for testing) / PL. The stored procedure queries from only one table and two columns are ignored because they are being phased out. I can run the stored procedure and preview the data in the DAL but when I create a page with an ODS linked to the DAL and a GridView I get this error. I checked every column that does not allow nulls and they all have values. I checked unique columns (ID is the only unique and is Identity=Yes in the table definition). I checked foreign-key columns for values that are not in the foreign table and there are none. Any ideas why do I get this?
Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.

Hi,
I am getting the above error when trying to load a report into my Web Application, I have tracked the error down to one specific field in my database. Even though this field is a NVarChar field and is of size 30 it would seem that there is an issue returning the value from the field. I can write it into the database no problems but when I try to get it out of the database it returns the above error.
e.g
MOB 401.908.804 - Fails
0401.907.324 - okay
8239 9082 (pager) - fails
Anyone got an idea on how to fix this????
Regards..
Peter.

I am testing Insert, Update etc. and messing up my database with "dirty" data. Is there a way to temporarily drop FOREIGN KEY constraints to truncate a table after testing without dropping the whole table and rebuilding it?

I installed sql server on one of my test servers, and I am eventually going to rename this server and put it into production. This server will replace one of my old servers with the same name. I was wondering if there was a way to rename the SQL Server instance after you rename your server without having to reinstall SQL Server. Thanks in advance for all the help.

I'm trying to create a local copy of a popular CRM database calledSalesforce.com. Many of the tables in the DB have FOREIGN KEYreferences that I want to preserve, but I've run into a chicken and eggproblem. Table "A" has a reference to table "B," and table "B" has areference to table "A." So I can't CREATE one until the other exists.Is there a way to disable these checks until I've created all theschema?Here's what I see (error first, then SQL that caused it):Server: Msg 1767, Level 16, State 1, Line 1Foreign key 'FK__UserRole__LastMo__48CFD27E' references invalid table'User'.Server: Msg 1750, Level 16, State 1, Line 1Could not create constraint.

Does anyone know how to tell sp_rename to look in a schema other than the default.
The code below reproduces the problem.
-- WORKS IN default schema
--
create table dbo.TestDF1(
dfField intconstraint DF1 default 0
)
go
sp_rename 'DF1', 'DF2', 'OBJECT'
go
Select name
From
sys.default_constraints
where
object_name(parent_object_id) = 'TestDF1'
go
drop table dbo.TestDF1
go
-- DOESN'T WORK IN added schema
--
create schema TestSchema
go
create table TestSchema.TestDF2(
dfField intconstraint DF3 default 0
)
go
sp_rename 'DF3', 'DF4', 'OBJECT'
go
Msg 15248, Level 11, State 1, Procedure sp_rename, Line 315
Either the parameter @objname is ambiguous or the claimed @objtype (OBJECT) is wrong.
---------------------------
drop table TestSchema.TestDF2
go
drop schema TestSchema
go

I have a SQL Server 2008 R2 Cluster. I have moved a file to another drive by adding a new file on the drive, doing a shrinkfile with emptyfile. I have removed the old file and when I try to rename the new file to the old files old name, I get an error.
ALTER DATABASE mydb REMOVE FILE myfilename
Msg 5009, Level 16, State 9, Line 1
One or more files listed in the statement could not be found or could not be initialized.
ALTER DATABASE mydb
modify FILE ( NAME = temp_filename
, NEWNAME = myfilename
)
Msg 1828, Level 16, State 3, Line 4
The logical file name "myfilename" is already in use. Choose a different name.
I have completed a failover, thinking the name was being held in cache. I've also renamed to something completely different then tried to rename to the old filename.

Is there any danger with renaming the LOGICAL file names behind the database?
There are a bunch of databases that were restored copies and all of them have the same logical database file name. I'm trying to get some growth data so I want the logical files to be different (prefer them to match the actual database name) so I can more easily identify them.
For instance:
database_id name type_desc name physical_name
1 DLMdb1 ROWS DLMDB1 D:dlmdb1.mdf
1 DLMdb1 LOG DLMDB1_log E:dlmdb1.ldf
2 DLMdb2 ROWS DLMDB1 D:dlmdb2.mdf
2 DLMdb2 LOG DLMDB1_log E:dlmdb2.ldf
3 DLMdb3 ROWS DLMDB1 D:dlmdb3.mdf
3 DLMdb3 LOG DLMDB1_log E:dlmdb3.ldf
Am I safe to rename the logical names? I can't think of anything that references those logical file names that I would be breaking [backups, applications].

I have two tables, T1 and T2.T1 has a foreign Key that refers to a key in T2.The way that I see it, its only possible to insert something into T1 ifthere already exists a tuple in T2 with the same value in key.That means that I always have to insert something into T2 before insertinginto T1Is that correct?

When following a script to create some tables and constraints, it is recommended that you name the FK constraint? Otherwise it appears with numbers after it. Is this the way 2005 creates them or has this always been the naming convention?

I want to disable foreign key constraints en mass. Is there a way to do this?
I know that I can go into each table and navigate to the Relationship tab of Properties and uncheck the "Enforce relationship for INSERTs and UPDATEs" box, but I'd much prefer to automate this process with a query since there are 160+ tables and probably 200+ relationships to disable.
I figure that sysconstraints my be the ticket, but I will keep experimenting until I get the right solution. In the meantime, any insight to steer me in the right direction is appreciated.

Hi All,
I know that when you specify a PRIMARY KEY or UNIQUE constraint for a table, SQL Server creates a unique index for the primary key columns.
What about foreign keys? Does SQL Server creates an index when you create a foreign key?
I have looked in Books Online and on the Internet, but couldn't find any information.
Thanks in advance.

I've recently implemented a whole bunch of foreign key constraints in a database. As a result I have issues every time I want to truncate a table to perform data loads.
Is there an easy way to tell the system to ignore these constraints for the term of a data load or truncation of data?
thank you

I have recently restored an SQL Server 2000 database on SQL Server 2005
A number of constraints on the database had previously been disabled
A monthly process that is carried out, imports data into 'Table A'.
This process now crashed, being unable to truncate table as it referenced by 'Table B'
Although when i check the properties of the constraint the 'enforce foreign key constraints' is set to no.
Is there a known issue with restoring databases on 2005,
Any help greatly appreciated.

I have table variable in which I am inserting data from sql server database. I have made one of the columns called repaidID a primary key so that a clustered index will be created on the table variable. When I run the stored procedure used to insert the data. I have this error message; Violation of Primary key Constraint. Cannot insert duplicate primary key in object. The value that is causing this error is (128503).
I have queried the repaidid 128503 in the database to see if it is a duplicate but could not find any duplicate. The repaidID is a unique id normally use by my company and does not have duplicates.

I have a table that I want to run an UPDATE statement to change some data in the table, but I get this error:
Server: Msg 547, Level 16, State 1, Line 1
UPDATE statement conflicted with COLUMN FOREIGN KEY constraint 'FK__Yield__Financial_Product__ProductCode'. The conflict occurred in database 'lsmdb', table 'Financial_Product', column 'ProductCode'.
The statement has been terminated.
How do I update the ProductCode column in both tables to reflect my updated data?
Thanks in advance.

CREATE TABLE IssueLog (
ItemNo int NOT NULL IDENTITY PRIMARY KEY

ON UPDATE CASCADE
ON DELETE CASCADE,
REFERENCES Approvals(ItemNo)
ON UPDATE CASCADE
ON DELETE SET NULL,
Msg 142, Level 15, State 2, Line 0
Incorrect syntax for definition of the 'TABLE' constraint.
I'd like to update or delete the IssueProgress plus update and setting null to the Approvals tables at the same time whenever the ItemNo of the parent table namely IssueLog is updated or deleted.
How can I achieve this?

How can I get and or set the order in which the cascading deletes of a table are executed??
I have table A with cascading deletes to Table B and Table C. Records in table B can not be deleted if they are referenced from table C. So if I delete C, then B and then A; that would work. But B then C and then A might be prohibited due to the constraint between B and C. Therefor the order of execution of the cascading delete is important.

When I checked sync status it has given the message like initial snapshot is not yet available.I started the snapshot and the subscription started replication records.When check at pup properties the value Copy foreign key constraints again false.
After changing the value to true it is showing as False.

Ok, so I've broken down and decided to write myself an invoicing
program. I'd like to use GUID fields as the Primary Keys in my
table. Now, I basicly bill for two seperate items:
Deliverables and Services.
So, my Layout's gonna look something like
Create Table Invoice(
ID UniqueIdentifier Primary Key,
-- Other Data
);
Create Deliverable(
ID uniqueidentifier Primary Key,
ParentInvoice uniqueidentifier,
-- Other data);
--...
Im sure there are probems with that as it's written feel free to edify me as to what they are.
my questions are such:
1) Does a uniqueidentifier field automagically get a value?
2) If not how do I generate one in TSQL?
3) If so, what do I use to store my Foreign Keys.
4) How do I declare my Foreign key constraints?

Guys,
I have 600 tables in my database, out of which 40 tables are look up value tables. I want generate truncate scripts which truncates all the tables in order of Parent child relationship excluding lookup tables. Is there any way to do this apart from figuring out Parent Child relationship and then writing the truncate statements for each of the table.
For example
EmployeeDetail table references Employee table
DepartmentDetail table references Department table
Department table references Employee table
My truncate script should be
TRUNCATE TABLE DEPARTMENTDETAIL
TRUNCATE TABLE EMPLOYEEDETAIL
TRUNCATE TABLE DEPARTMENT
TRUNCATE TABLE EMPLOYEE
Is there any automated way to figure out parent and child tables and generate truncate script for the same.
Thanks

SQL Server 2000:
Question 1
If you drop / rename a table and then recreate the table with the SAME NAME, what impact does it have on stored procedures that use these tables? From a system perspective, do you have to rebuild / recompile ALL the stored procedures that use this table?
I had a discussion with someone that said that this is a good idea, since the IDs of the tables change in sysobjects and from a SQL SERVER query plan perspective, this needs to be done...
Question 2
If you Truncate a Table as part of a BEGIN TRANSACTION, what happens if an error occurs? Will it Rollback? The theory is that it won't because Truncate doesn't utilize the logs where as Delete From uses the SQL Logs?
Thanks!

Hi,
We're having a few linked servers in our company. some tables in one of the linked servers include columns (better saying, foreign keys) of tables in another server. I wonder if there's a way to create a foreign key referencing one column in another server. That is, suppose there's Column A in table A in Server A which references Column B in table B in server B, is there a way to create column A as foreign key referencing column B?
Any idea is appreciated.
