Thank's for help!!!
Resolved the problem, but now I don't find registers that began with the
letter Y and Z.
Is that a problem of FB 2.0 or of the component TIB_IncSearsh?

Assunto: RES: [IBO] FB 2.0 com IBO 4.7.16 - Order of the null fields
Is there some form of being how default, and not to need to place in each
clause order by?
For the database or for the component?
Thankful
Hello Nelson,
That's right: in Firebird 2 nulls appear at the "smallest" end of the
sort (unless overridden by NULLS FIRST/LAST). In Firebird 1.5 they
appeared at the tail end (unless etc.)
It's not a problem, it's a solution :-)
And you can always override the placement in your ORDER BY clause.

Hello Nelson,

That's right: in Firebird 2 nulls appear at the "smallest" end of the
sort (unless overridden by NULLS FIRST/LAST). In Firebird 1.5 they
