Colum Name - Alias
Aug 10, 2007
We are thinking of using general purpose column names in our application schema. We want to give the option to the end user to customize the filed names to fit their business . We want to build the functionality on the generic names so that it will work for multiple customes.
Example: We may want to have 10 Strings, 10 numbers and 5 booleans pre defined and reports running off of the table. The customer can name first number as pressure, second one for length and map their data to the table. Other customer can use the first number for temperature and the second one for width.
Is there a way to do it in SQL server w/o having a lookup table for column name aliasing?
Thanks

We will be moving 2 different databases (SS2005 & SS2008) to a new SS2014 SQL Server. Currently our codes looks something like Server1DBInstance1... & Server2DBInstance2... Is it possible to move the objects from these 2 instances to Server3DBInstance3 and then use an alias to reference the objects? Or does Server3 need to have DBInstance1 & DBIstance2? Basically, is the alias just for the database or for the instance too? Can I create an alias "Server1DBInstance1' on Server3DBInstance3 and assign objects to that alias?

i wonder what is the best approach to use !!!i have creditLimit column in Customer Table the default value will be 500 and this limit to allow users to send sms from my website ..... every month they will be allowed to send 500 sms referring to the credit limit column.... now !!if the user sent today some sms and after few days sent another 20 and after one week he sent 150 SMS as a total so that means he has only 350 SMS as credit to use this month!!!so what is the best approach to implement this solution ? shall i have another field in the table called 'CreditUsed' and that will be updated each time the user will send SMS and this value will be compared with the credit limit ORi use the formula for the column to calculate the credit left and do the maths !!!what is the best approach as you think ???thnaks for reading this question !!

Hi All,
Just want to know if a column with IDENTITY can be altered. If yes, how?
I have a table with colum defined like this:
CREATE TABLE [dbo].[Test] (
[TestID] [int] IDENTITY (1, 1) NOT NULL ,
.......
Through ALTER TABLE script (I don't want to do it through Enterprise Manager) I want it to be like this:
CREATE TABLE [dbo].[Test] (
[TestID] [int] IDENTITY (1, 1) NOT FOR REPLICATION NOT NULL ,
.......
I want the constrain "NOT FOR REPLICATION" done through ALTER TABLE script. Is that possible?
Please let me know with the syntax.
Thanks

FROM #Sec INNER JOIN
Pos ON #Sec.ID = Pos.ID
WHERE (Pos.PID = 'G')
UPDATE #Sec
WHEN (Pos.PID = 'C') THEN SET C2005 = Pos.USD / 1000 end
WHEN (Pos.PID = 'G') THEN SET G2005 = Pos.USD / 1000 end

Hi all, I am trying to sum a column into different variables depending on another column. Let me explain my self better with an example
DECLARE @Initial decimal(18,2), @incomings decimal(18,2), @outgoings decimal(18,2)
SELECT
@initial = CASE WHEN type = 1 THEN SUM(amount) END,
@incomings = CASE WHEN type = 2 THEN SUM(amount) END,
@outgoings = CASE WHEN type = 3 THEN SUM(amount) END,
FROM Transactions
WHERE date = '05/14/2006' AND STATION = 'apuyinc'
GROUP BY type, amount
What I am trying to do is to sum all of the incomings transactions into @incomings, all of the outgoing transactions into @outgoings and the initial transaction into @initial where
The incoming transactions is type 2,
outgoing transactions is type 3
Thanks for the help

In SQL7, if you add a column to a table, is it necessary to recompile all
stored procs that reference that table?
Under 6.5, this caused problems at our site unless the Procs were 'refreshed'.
Is this only necessary where select * is used?

THe unique Id column is set to identity seed. Yet when transfering 1500 records it fails to stuff them all becuase it says there is a NULL in unique id column.
"Cannot insert the value NULL into column UID column does not allow"
Yet in the transformation screen I am setting the UID column to <ignore> meaning I do not have that value in my source and I am wanting the destination table to do it's thing and incrememnt by 1 the identity seed.
Is this common?
THe source and destination tables are in the same databes.

I have a complex view in my sql 2005 database.
The view returns a column that could be null (as the result of a left outer join).
The coulmn that is returned is an integer.
Everything works fine if I run the view from SQL 2005 Management Studio.
My column value is always null if I use ADO.NET's SqlAdapter to return a DataTable.
Has anybody seen this behaviour before?
Any help appreciated.
Regards,
Paul.

I like to define my procedure parameter type to match a referenced table colum type,

That way, when the table column is changes, I would not have to change my stored proc.

We have an alias for dbo in various code areas, development/test/production. It was easy to tell the DBO alias
on release 6.5 but now on 7.0, the only way I can figure out if the userid is aliased to dbo is to sign on as the userid
and query 'select user_name( )' and if it returns dbo, I have the answer. Is there an easier way to do this by looking in a
system catalog or is there something else I am missing? Thanks in advance. Karen Suenram

In 6.5 you could alias someone as dbo, thus preventing an ownership chain break. In 7.0 there are roles, one of which is db_owner. I gave a user db_owner role, and they created a table. But no one else can see it? And he is listed as the owner in EM. How do I more effectivly mimic the dbo alias available in 6.5?

Hi All,
I've just installed an active/active sql cluster. Both are named instance hence if i need to connect to it, I need to use NODE1SQLINST1 and NODE2SQLINST2. Is there a way to just use NODE1 or any other single name to connect to the sql instance? I was looking at Alias but I can't get it working. Anyone has any ideas or suggestion for me? Reason why i want to do this is in an odbc connection, instead of using NODE1SQLINST1, I can use NODE1.
Thanks
