I have the need for updating multiple fields in a record.
The table name is kontingent. My sql statement look like this.
MySql = "UPDATE Kontingent SET(Jan, Feb, Mar, Apr, Maj, Jun, Jul, Aug, Sep, Okt, Nov, Dec) = (2,2,1,1,1,1,1,2,2,2,2,2) WHERE MemID =18"
I am updating another table before this one and it works fine,
but when I excecute the statement.
set objRS = objDC.Execute(MySql)
I get the page is not available. Can anyone see what is wrong in my sql string. Thanks in advance.

You need to pass the values 'one by one', like this:
UPDATE Kontingent SET Jan = 2, Feb = 2, Mar = 1 ...
Håber det hjælper...

Hi Jonax
Thank for your reply
I was afraid that this might be the problem, but others tell me that the following syntaks should be possible.
"
It is also possible to UPDATE multiple columns at the same time. The syntax in this case would look like the following:
UPDATE TABLE "table_name"
SET ("column_1", "column_2") = ([new value 1], [new value 2])
WHERE {condition}
"
Ha en forsat god dag.

Hi again,
I have never seen that syntax used - have a look here: http://www.mysql.com/doc/en/UPDATE.html

Hi Jonax
Your link basicly shows your first idea. My logical sence tell me that it can't be true that one have to send multiple commands to update one record. My first suggestion came from here. http://www.1keydata.com/sql/sqlupdate.html
They can of course be wrong, but it make sence.
Cheers

I shan't say they're wrong - but as previously mentioned - it's not a syntax that I reckognize. The syntax I'm suggesting doesn't mean that you have to send multiple commands - you can update many fields using one statement...
UPDATE Kontingent SET Jan = 2, Feb = 2, Mar = 1 WHERE MemID = 18
By the way - what database are you using, and are all of your fields of type INT?
