Hi,
Say I have a table with column A, B, C, D
A has a unique index on it (primary key)
B and C have a normal index on it
D has no index
If I perform a query like update tbl set D = 'whatever' ;
that should make no difference on the indexes on the other columns,
right ?
Or is there some kind of mechanism that does create a sort of new
record, thus makes the indexes go wild.
Met vriendelijke groeten,
Bien à vous,
Kind regards,
