Subsequent calls to ibase_fetch_object()
return the next row in the result set, or FALSE if there are no
more rows.
fetch_flag is a combination of the constants IBASE_TEXT and IBASE_UNIXTIME
ORed together. Passing IBASE_TEXT will cause this function to return BLOB contents
instead of BLOB ids. Passing IBASE_UNIXTIME will cause this function to return
date/time values as Unix timestamps instead of as formatted strings.
