Are filters in edb different from dbisam?

RI is the standard. dbisam does not have ri. Is this bad, if
ri is enforced by code?

Sanford,

They're pretty much identical except for the collation comparison portion:

You can force a specific type of collation on a column reference like this:

MyColumn COLLATE ANSI_CI = 'Test'

The above example will force the optimizer to use the case-insensitive ANSI
collation to perform the comparison.  In DBISAM, the equivalent would be:

UPPER(MyColumn) = UPPER('Test')

<< RI is the standard. dbisam does not have ri. Is this bad, if ri is

It really depends upon how "public" the database is.  If the database can
only be accessed via your application, then the answer is no, it isn't bad.
