I don't remember Access-specific DDL queries too well, but I'd guess it's:

ALTER TABLE ttt CHANGE COLUMN aaa bbb INT NOT NULL;

you need to add a reference to the ADO Extensions for Security and Data Definition (ADOX)

then you can use the ADOX.Catalog and ADOX.Table objects

Sorry I repated it
on
http://www.experts-exchange.com/Programming/Programming_Languages/Dot_Net/VB_DOT_NET/Q_22078122.html
and had the answer

I believe the only way you can accomplish this is by:

1)  Adding a column:

ALTER TABLE yourTableName ADD COLUMN NewName datatype(size)

2)  Run an update statement to copy the data from the old column to the new one:

UPDATE yourTableName SET NewName = OldName

3)  Then drop the old column:

ALTER TABLE yourTableName DROP COLUMN OldName
