Alter Table should fail on a multi-membered file. Not SQL-elian.
Only some specific actions like ADD CONSTRAINT will be prevented for
an SQL ALTER TABLE on multiple member [i.e. non-SQL TABLE] database
files. A simple ALTER COLUMN SET DATA TYPE CHAR(100), for example, will
not prevented simply due to MAXMBRS(greater-than-1) nor actual member
count greater than one. An attempt to add a constraint for instance,
would be diagnosed as an error and prevented by SQLCODE -7008. A SQL
TABLE with multiple partitions [implemented as members] are not
restricted in the same manner. The attempt to ALTER TABLE of a Source
Physical File, however, I confirmed [on v5r3] fails with -7001; as "not
a database [data] file" versus being due to multiple members.
