Subject RES: [IBO] FB 2.0 com IBO 4.7.16 - Order of the null fields
Author Nelson - Terra
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?

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

I guess you mean: before updating to Firebird 2?

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.
