SQL 2012 :: Script To Remove Any Foreign Characters From Table
Sep 14, 2015I have a table that is riddled with weird characters. So far I have found an escape character for PDF files and a trademark sign. These characters are crashing my SSIS packages. I am able to remove these characters with an update script...
Update TABLE
set LEAD_NOTES__C = Replace(LEAD_NOTES__C, nchar(65533) COLLATE Latin1_General_BIN2, '!');
Update TABLE
set LEAD_NOTES__C = Replace(LEAD_NOTES__C, nchar(1671) COLLATE Latin1_General_BIN2, '!');
This works fine, but my question is...
I would like to write a script that removes all foreign characters with the exception of the normal characters like (@,#,$,%,etc). I need a dynamic process that handles this so I am not losing time sifting through over 20,000 rows of data and changing my update script to remove a specific column. Although this method works, I would prefer a dynamic query. I intend to wrap this in a stored procedure that loops through all columns in a table (as parameter).
DB Design :: Remove Foreign Keys For Audit Columns?
Aug 25, 2015We have a database with hundreds of tables, each with "CreatedByLoginId" and "ModifiedByLoginId" FK columns back to the Login table. Â This is all fine and well, but 500+ tables all link back to Login table every time a record is inserted or updated.
For strictly performance reasons, what do you think of us REMOVING the FK constraints on all of our tables? Â While this does mean that a GUID that is not a valid LoginId could potentially be put in a table, I'm not too worried about it because users don't have direct access to the database.

Oct 12, 2006I have uninstalled the CTP version of the SQL Server express so that I can install the released version but CTP version is still listed in the add/remove program list but without the change/remove button. I have been to different sites to find information on cleaning this up and I have ran all the uninstall tool I can find but the problem still prevails.

Sep 14, 1998Hi!
Is it possible in SQL 6.5 to create a Foreign Key on a field that
has a datatype of SMALLINT? I have created FK`s with
other datatypes, but it doesn`t seem to work with this particular
datatype. Is there some trick to this?
Thank you for your assistance!

Jun 5, 2007I would like to create a foreign key but the Primary table has 2 fields as it Primary Key. Is there a way to create a Foreign Key that links only on one field of the primary key.
Ex: table 1: id int , language char(2), description varchar(100) PK = ID + language
table 2 : id int, idlanguage int PK = id FK (idLanguage refers to id from table 1)
This cause an error because the foreign key does not include all part of the primary key.

Getting Rid Of Foreign Key, How Do I Do That
Apr 13, 2008Hi everyone,
My main table has a column named "customer" which is a foreign key pointed to my secondary table consisted of a column "customer_id".
I wanted to change my secondary table's customer_id's name into another name whereby deleting it and create a new column instead (i dont know another way of changing names by code) but i'm not allowed to do that due to "customer_is"'s being attached to my main table as FK.
Any suggestion how to do it ?
Thanks a lot.

How Do I Create A Foreign Key
Apr 27, 2007I have a one to many relationship between two tables. The master table is keyed using an int ID field set to IsIdentity yes and this is the primary key. The field name is ChurchID. Likewise the detail table has such a field as it's primary key and is named ContactID.
I carry the ChurchID field in the detail table and would like to make it the foreign key. I could not find this explained in the two books I have and the help was anything but that )perhaps it's just me afterall).
Well, any help in this matter would be greatly appreciated as I find myself at a standstill until this can be resolved.
Thanks in advance.
Help With Foreign Key Relationship
Jul 3, 2007When I try to insert a record on my DB (SQL 2005 Express) I get a constraint error. This is my table setup which has been simplified to expose the problem I have:
Categories TABLEint CatId PKvarchar CatName :
Items TABLEint ItemId PKvarchar ItemName :
X_Items_Categoriesint CatIdint ItemId
So basically I have a one-to-many relationship between Items and Categories, in other words each item is associated to one or more categories and this association is done via the X_Items_Categories cross table. On this cross table I set two constraints:
The CatId of each entry in the cross table (X_Items_Categories) must exist in the Category table, and

Foreign Key Problem
Mar 13, 2008I'm trying to enter data into a SqlServer 2005 database programatically. The databases are part of an open source program I have. I'm encountering the following error when I try to enter data into a particular table:The INSERT statement conflicted with the FOREIGN KEY constraint "FK_CMRC_ProductImages_CMRC_Products". The conflict occurred in database "hscom", table "dbo.CSK_Store_Product", column 'productID'. The statement has been terminated. I understand what's happening theoretically, but I don't know where to look for where the constraint is defined, or how to fix it. I don't see FK_CMRC_ProductImages_CMRC_Products as a file name or a stored procedure. Diane

Foreign Key Tangle
Aug 12, 2005I'm using stored procedures to update my tables. If I disable the foreign key constraint all works perfectly. Otherwise I get this error:INSERT statement conflicted with TABLE FOREIGN KEY constraint 'FK_wansub_invoice'. The conflict occurred in database 'test1', table 'invoice'. The statement has been terminated. I don't understand why I'm getting the error, because when I disable the constraint even the foreign key fields are updated properly and there is no apparent conflict with the linked table. I've included my c# code and the stored procedure below.FYI the foreign keys in question are InvoiceDate, AccountNum, CarrierId, and Cycle. These are the primary keys in the "invoice" table, and foreign keys in the "wansub" table. It is vital that all records in the wansub table are matched with a record in the invoice table, so I have to have this constraint in place. C# code to create parameters and call the sp:

Conditional Foreign Key - Can It Be Done???
May 17, 2001Hello Folks,
Well I've hit the wall on this one:
I'm wondering if one can designate a conditional foreign key that relates to one of many different tables depending on the "type" column in the foreign key's. My goal is to come up with some SQL code that will allow for this in a Create table statement. (By the way I'm using MS SQL-7 but I'm wondering if this can be done in general.)
I have two simple cases below that show illustrate what I'm trying to do:
Thanks in advance, -JerryZZ
---------------------------------------------------------
Case 1: The foreign key relation is to a primary key
Table: Invoices
-Fields:
---InvoiceID ..... (primary key)
---BilleeID ...... (fkey to Manfacturers.ManfID IF BilleeType=M)
...................(fkey to Distibutors.DistID IF BilleeType=D)
---BilleeType .....(constraint = M or D)
Table: Manufacturers
-Fields:
---ManfID ........ (primary key)
---CompanyName.. (not null)
Table: Distributors
-Fields:
---DistID ........ (primary key)
---CompanyName .. (not null)
---------------------------------------------------------
Case 2: The foreign key relation is to a unique "not null" non-primary key
Table: InvoicesEmail
-Fields:
---InvoiceID ..... (primary key)
---EmailAddress .. (fkey to Manfacturers.EmailAddress IF BilleeType=M)
...................(fkey to Distibutors.EmailAddress IF BilleeType=D)
---BilleeType .....(constraint = M or D)
Table: Manufacturers
-Fields:
---ManfID ........ (primary key)
---EmailAddress .. (unique, not null)
Table: Distributors
-Fields:
---DistID ........ (primary key)
---EmailAddress .. (unique, not null)
