is there a way to do this in create/alter table without the overhead of a trigger? I want to ensure that one of the 'key' values (even though it may be duplicated) cannot change after it's been inserted.
View 4 RepliesQuestion is pretty much in the thread title.
I'm still plunking away on a history trigger that requires the evaluation of whether or not each column has been updated. If it has,t hen I'll be tossing a record into a history table.
Basically I need something to function along the same logic as this:
IF UPDATED(@s)
BEGIN
--some code
END
Any thoughts you folks may have are greatly appreciated.

Hi,
Can anybody tell me how to find the column name(s) for recently updated table.
Thanks,

If your tables contain created and modified/updated dates what is the best practice for these?
1. Should you use UTC dates?
2. Do you use a default for the creation date (I assume yes)?
3. Should you create a trigger to handle the last update date? Or do you update the column directly in your stored procedures that modify data?
Also, as an aside if you store the user who created/updated the record do you store a foreign key reference to the user table or do you store the username as a varchar? Of course I know you'd normally store the fk, but I wasn't sure if the "logging" nature of the column suggests storing a string value.

In MySQL it's simple to insert new columns in specific locations in a table like this
sql Code:
Original
- sql Code
alter table foo add column bar integer not null default 0 after baz
ALTER TABLE foo ADD COLUMN bar integer NOT NULL DEFAULT 0 AFTER baz
But attempting to do the same thing in MSSQL fails with a syntax error on the word "after." I can insert columns in MSSQL but only if they are added to the end. I looked at the Microsoft insert documentation here but don't see any way to replicate the above MySQL command.
Is there any way to do this in MSSQL? Or do I have to completely recreate all my tables from scratch?
Thanks for any help

I want to write SQL that will search the tables in a database for a specific column, like this. For instance, I have a column "Unique_ID" that is in many of our tables (hundreds) but not in others and want to find out the tables it is in. It is always the first column.
I tried to find a system stored procdure to do this but couldn't and tried to create a script using the sysobjects and syscolumns tables in the Master db, but came to a roadblock because they don't seem to be related at all.
I would surely appreciate if someone else has already done this!
Thanks!

I am building a data warehouse. I have many columns I want to populate in a fact table using integration services. Sample fields are: companyID, companyName, companyNumberOfAccounts, company, NumberOfUsers.
In the integration services package, I would like to keep this fact table in place and populated with data and to build integration services packages that update each of the existing row's specific columns (e.g. companyNameOfAccounts) one by one. For example, I have a source of data that has companyID and companyNumberOfAccounts data.
Is it possible to use the SQL Server Destination or OLE DB Destination Integration Services elements to import companyID and companyNumberOfAccounts data so that existing records just have their companyNumberOfAccounts column updated?

View 3 Replies View RelatedI want to set a column to 0 if it is set to a certain number. There are several columns to check though, so I am wondering if I can do it all in one query, or if I have to do it in single queries?
here is an example:
account | contact_id_1 | contact_id_2 | contact_id_3
433 | 67 | 23 | 67
so I want to set any contact_id_N = 0 where contact_id_N is = 67
so in the end, the table will look like this:
account | contact_id_1 | contact_id_2 | contact_id_3
433 | 0 | 23 | 0
is there a way to do it in one statement?

I've got an OLEDB DB2 linked server to a db2/AS400 instance and selecting from a table on the server has never caused problems before. One of the columns is a large text field. If I select all the columns but the large text field, it returns as normal, but including the large text field now, I get:
"Transport error: shared memory provider error: 0 - no process is on the other end of the pipe"
The largest entry in the text field is about 5k characters, and there don't appear to be any strange characters.
I need to insert and update a table. One column of the table needs to conform to a format as: XXXXXXX.XXXXX
If any data is not complying to the format an error needs to be thrown.

I have huge export files in a DB and i need to check if there are any datasets that have the same value in the first column, but a different in another one, via a query of course.
Like this:

3 0
1 0
The expected ID i get as a result of my query should be 1 in this case.
