select t.* from table t where field1 like '%'||t.field2||'%'这种可以匹配比如
a,b,c,ab,bc,abc在字符串abc中,但是你说的那种满足不了,不好意思,能力有限
select t.* from table t
where substr(field1,1,1) like '%'||t.field2||'%
and substr(field1,2,1) like '%'||t.field2||'%
and substr(field1,3,1) like '%'||t.field2||'%
and substr(field1,4,1) like '%'||t.field2||'%
