I droped back to 3.06Ca by uninstalling 3.06Cf (wiping the IBObjects dir and
the IBO bpl's and lib's) and installed only the 3.06Ca and not the f sub
release and everything worked fine. So there is a problem somewhere between
the a and f subrelease for BCB users and ParamByName.

No. I made a dummy variable of AnsiString and assigned
DirQuery->FieldByName("STID")->AsString to it and it worked fine. I just
compiled the blob insert sample because it uses a DSQL component and it has
the same Access Violation at the same memory location. I hope it is not a
quirk with 3.06 Cf and BCB 5.

Is DirQuery somehow getting closed before the assignment?
