Hi,

Using fb1.5, unified interbase components 1.2d, delphi 7, WXP:

//uib dataset descendant
dsGen:=TBesDataSet.Create(database);

//we make an update (doesn't fail if it's a select)
dsGen.add('update documentos_gen set doc=?doc where docn=?docn');

//we open the dataset without bind the parameters
dsGen.open;

-> Firebird service hangs

Regards,

Pere Vilas Mari.
