>>You mean for transaction handle? This really depend what client library do. I do not go into details about client libraries which i do not write, but i am talking abut transaction numbers. This was only sample where it can be usefull.
For me it will be usefull in application developement. In some applications i e.g. remember OAT and then query against RDB$RECORD_VERSION. And i have some old application where transaction id can be remembered as integer not int64. I can e.g. have in a grid remembered field from MON$ table as Integer not Int64 and application raise an error. regards, Karol Bieniaszewski Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
