Add Fields in a table

ALTER TABLE table {ADD {COLUMN field type[(size)] [NOT NULL][CONSTRAINT index] | CONSTRAINT multifieldindex} |DROP {COLUMN field I CONSTRAINT indexname} }

Description
 
table
 The name of the table to be altered.
 
field
 The name of the field to be added to or deleted from table.
 
type
 The data type of field.
 
size
 The field size in characters (Text and Binary fields only).
 
index
 The index for field. See the CONSTRAINT clause topic for more information on how to construct this index.
 
multifieldindex
 The definition of a multiple-field index to be added to table. See the CONSTRAINT clause topic for more information on how to construct this clause.
 
indexname
 The name of the multiple-field index to be removed.
 

Use ADD COLUMN to add a new field to the table. You specify the field name, data type, and (for Text and Binary fields) an optional size. For example, the following statement adds a 25-character Text field called Notes to the Employees table:
ALTER TABLE Employees ADD COLUMN Notes TEXT(25)
You can also define an index on that field. For more information on single-field indexes, see the CONSTRAINT clause topic.

If you specify NOT NULL for a field, then new records are required to have valid data in that field.

So, I just need the command object to run that query?
Is there any way that I can use Field Coleections to append the data.
I tried using field collections, but I get this erroe messsage
****************
ADODB.Fields error '800a0c93'

Operation is not allowed in this context.

/fiber/addfield.asp, line 18
*****************

Line 18 : rsX.Fields.Append "Node2", adVariant

"Field Collections to append the data"?  You lost me...

What are you trying to do?

First, I would like to check if the field exists.
I use field collections for doing this check.
Then, if the field does not exist, I add a new field.
I am trying to use field collection also for this action.
I use append method as I typed above.
Am I using wrong way?

You mean like this?

RS.CursorLocation = adUseClient
RS.Fields.Append "Name", adBSTR
RS.Fields.Append "City", adBSTR
RS.Open
RS.AddNew

MGFranz,

That's what I meant with Field Collections.
Does that method work?

I already tried using Alter Table as you suggested, but I got this error:

************
Microsoft OLE DB Provider for SQL Server error '80040e14'

User does not have permission to perform this operation on table 'PCLinks'.
*************

I gave full permission to Public in SQL Server, but I still have the same error message.
What's wrong?

Thank you

Hmm...

Please use 'Reload Question' from top right corner and don't keep pressing F5/Refresh.

Fields collection cannot be appended as you are trying to do.

You might be connecting to a SQL server as a different user from Query Analyzer and yet another user when connecting from ASP. See your connect string for details.

I guess it is only fair to assign points to mgfranz if Budenk fail to reply within the 72 hours grace time.
