关于 between and~~~~~~~~`

如果在daa091.jdds1,daa091.jdds2这俩个字段之间 skqk的值就写I

这样可以的，不过你先要确定是daa091表的哪一条记录 然后 把daa091.jdds1,daa091.jdds2换成： select jdds1  from daa091 where ....
     select jdds2  from daa091 where ....

yourapy

between x and y,x,y皆是常数。
adoquery1.sql.add('
update daa074 set skqk=''i''
from daa074 a
where daa074.elsyds >=(select daa091.jdds1 from daa074 where id = a.id) and daa074.elsyds <=(select daa091.jdds2 from daa074 where id = a.id)
');
其中的ID字段换成该表的关键字字段
