转义字符%

sprintf（SQL, select * from jgxx where jgbm like '%s%%', jgbm) 假如机构编码为'100', 这样会变成select * from jgxx where jgbm like '100_%', 多了个'_', 原本我想要100%，这种怎么解决，还有就是，如果是2%%，就不会出现这种情况，直接就回变成2%，是较为正常的，这是怎么回事儿呢

with t as
(
select '123%_323' a from dual
union all
select '1231%%%' a from dual
union all
select '12312312' from dual
)

select t.*
from t
where t.a like '%\_%' escape('\')
 or t.a like '%\%%' escape('\')
