I'm dealing with a database with tables that have freaking columns.
Partial DDL:
Create table [tbl IMN] ([Ave Cost-Mn] varchar(10))
-- yeah, this column contains string value
Now, I'd like to rename all these freaking columns without special
charaters like '-', 'whitespace' etc systematically (meaning loop
through all tables and columns dynamically). It seems that the
sp_rename proc can't handle some function call or ...?
e.g.
exec sp_rename '[tbl-IMN].[Ave Cost-Mn]',replace('[Ave
Cost-Mn]','-',''),'COLUMN'
better if it can work,
exec sp_rename '[tbl-IMN].[Ave Cost-Mn]',replace('[Ave Cost-Mn]','-|
',''),'COLUMN'
TIA 6 3212

Correct. In difference to most other languages, you cannot pass
expressions as parameters to stored procedures. You can only psss
constants and variables.

How about this? Rather than a stored procedure, generate a script to
run against all of your columns, like so:
SELECT 'exec sp_rename ''' + Table_Name + '.'
+ Column_name + ''', ''' +
REPLACE(COLUMN_ NAME, '-', '') + ''', ''COLUMN'''
FROM INFORMATION_SCH EMA.COLUMNS
WHERE COLUMN_NAME LIKE '%-%'
Cut and paste the results of the query into a new QA window and execute
the statements.
HTH,
Stu
Actually, I could do something like
select @colTemp = Replace(col,'-','')
then
exec sp_rename '[tbl-IMN].[Ave Cost-Mn]',@colTemp,'COL UMN'
I thought about that before posting but I did not try (just don't know
why somtimes I'm so freaking lazy).
Thanks for the note though.

Interesting idea, however, I don't think it works.
Worked in my test bed; what error did you get? Just to make sure that
I was clear, the above command will NOT execute the stored procedure;
it'll just generate a script of all the columns in all the tables in
your database with a '-' in the name, like so:
exec sp_rename 'SPLAT.Check-ID', 'CheckID', 'COLUMN'
exec sp_rename 'SPLAT.Check-ID2', 'CheckID2', 'COLUMN'
You have to cut and paste that script into a new window in query
analyzer to actually execute the changes.
You could, of course, modify the SQL statement to actually execute the
stored procedure for you; I just prefer to do it this way so I can
visually check what I'm about to execute.
Stu
Yeah, I see. Problem resolved. Thanks though.

My understanding is that using reserved words as column names is
allowable as long as they are quoted. I am trying to create a table
dynamically with columns defined by the first row of a text file I
import. Unfortunately, I have no control over the column names and
the data provider has chosen to use the word "USE" as a column name.
"USE" is a reserved word.
To handle this, I tried quoting the word during the CREATE TABLE

Folks,
I have a table of addresses and a seperate table with contact names -
All addresses tie to one or more names - I would like to keep track of
the number of names 'belonging' to an address and have thus included a
column in my address table called num_of_contacts. Everytime I add a
new contact, I would like to increment the num_of_contacts column in the
address table.
Is this possible?

Hi
I have been working since 2 days to device a method to export sql table
into csv format. I have tried using bcp with format option to keep the
column names but I'm unable to transfer the file with column names. and
also I'm having problems on columns having decimal data.
Can any one suggest me how to automate data transfer(by using SP) and
retaining column names.
Thanks
