Update of /cvsroot/firebird/interbase/jrd
In directory slayer.i.sourceforge.net:/tmp/cvs-serv3230/interbase/jrd
Modified Files:
evl.c
Log Message:
* Modified by: Patrick J. P. Griffin
* Date: 11/24/2000
* Problem: select count(0)+1 from rdb$relations where 0=1; returns 0
* In the EVL_group processing, the internal assigment for
* the literal in the computation is being done on every
* statement fetch, so if there are no statements fetched
* then the internal field never gets set.
* Change: Added an assignment process for the literal
* before the first fetch.
