Formula Column
Jul 20, 2005
Hi,
I would like to create a calculated column using the formula
section for a table. I am having some trouble doing this.
The table's name is ReportParameter. The calculated column's name is
tbcalculatedcolumn and tb1 and tb2 are boolean columns in the table.
I would like to use an If then statement such as the following (in
psuedo code):
If tb1 = 1 then tbcalculatedcolumn = 1
Elseif tb2 = 1 then tbcalculatedcolumn = 2
Endif
Thanks for the help,
Bill

I have downloaded the SQL Server Books online and found the section on Computed columns. In my small banking program I have columns named Deposit/Withdrawel and Balance. If I am reading this right I need to set the Computed Column Specification of my Balance Column in order to perform the calculation. My problem now is that I have no idea how to word the formula and other than telling me what a formula is the SQL Server Books online is no help whatsoever, so any help would be awesome.
If i've misunderstood what I am meant to do somebody please please tell me. Thanks

I am trying to do the following.
While inserting a record into a table I need one field to be created based on a stored procedure output.The stored procedure will create something like this, "XX-mm-yyyy-incremental number which resets to zero at the end of every month". All other field except the Identity field and the above mentioned storeproc generated field will be inputted manually. How can I do this?
Thanks
Hope my question is clear enough.

Is it possible to retrieve the formula associated with a computed column using t-SQL? I can use COLUMNPROPERTY( id, column, 'IsComputed') to find the computed columns, but how do I get the formula itself?
Thanks,

Good day!
What is the syntax on calling a function from a column formula in an MS SQL table.
I created a table, one column's value will be coming from a function. And at the same time, I will pass parameters to the function. How do I do this? Is this correct?
SELECT dbo.FunctionName([Parameter1, Parameter2])
But i can't save the table, "Error validating the formula".
Pls. help
Thanks a lot.

I'm trying to write a query that will display the formula for a computed column in SQL Server 2008R2.
I have looked here: [URL] ....
and it say (at least I think) that I can look at the Formula property of COLUMNPROPERTY like this:
SELECT COLUMN_NAME ,
COLUMNPROPERTY(OBJECT_ID(TABLE_NAME),COLUMN_NAME,'IsComputed'),
COLUMNPROPERTY(OBJECT_ID(TABLE_NAME),COLUMN_NAME,'Formula'),
COLUMNPROPERTY(OBJECT_ID(TABLE_NAME),COLUMN_NAME,'IsDeterministic')
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'Event' AND COLUMN_NAME = 'CurrentAttendance'
I know the column is computed and I can see the formula in SSMS. I wanted to do this in T-SQL. How to get this value?

I want to create a computed column with this formula:
ISNULL(NULLIF (tot_mnc, 0) / NULLIF (repl_value, 0), 0)
It works in a straight select query, but when I put it in the formula of the table design window, I get an error "Error validating the formula for column 'test_fci'"
I don't know if it's relevant but repl_value is itself a computed column with the formula:
(repl_value_e_g + repl_value_aux)
Is it possible to use the system functions in a computed column? If not, how would I pass those values into a udf and use it for the formula?
Thanks.

I'm trying to replicate client data from multiple databases into a single table. So database A, B and C replicate client data to a table in database Z. There is a settings table on A, B and C that holds the businessID and I use a function in a computed column to add this to the client table. At the moment I have just database A and Z as a test and what happens is the computed column gets replicated as a computed column with the formula.
Can I change this so that I can replicate the computed value (at db A,B,C) of this column?
I don't really want to add a businessID to the table if possible as I'm going to need to add a number of other tables to this replication which will each need to have the businessID, a computed column would be much easier and save updating a load of scripts.
If the above is not possible is there some other solution available so I can identify which database the records came from in the table on database Z?

This gives me my total correctly:([rush24] + [rush6] + 50)
All column are numeric(9) except the "total" column which is numeric(13).
