Lele,

OnPrepareSQL is called, when IBO detects that the Query has to be
prepared again. If you are in SearchMode, and you dont alter any of
your data aware controls (IB_Edit´s,LookupCombo, ...), so there is no
need to prepare the Query again. If your Memo is not a TIB_Memo, but it
is altered within the SearchMode, you have to call InvalidateSQL to notify
IBO that the SQL has to be prepared again. After doing this, OnPrepareSql
will be called !
