[GitHub] [doris] alenfive opened a new issue, #13325: 自动类型转换无法正确应对bigint数据类型[Bug]

URL: https://github.com/apache/doris/issues/13325

   ### Search before asking
   
   - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues.
   
   
   ### Version
   
   0.15.0-rc04
   
   ### What's Wrong?
   
   ```
   CREATE TABLE `tb1` (
     `user_id` String NULL COMMENT ""
   ) ENGINE=OLAP
   DUPLICATE KEY(`user_id`)
   COMMENT "OLAP"
   DISTRIBUTED BY HASH(`user_id`) BUCKETS 8
   PROPERTIES (
   "replication_allocation" = "tag.location.default: 1",
   "in_memory" = "false",
   "storage_format" = "V2"
   );
   
   ```
   `insert into tb1(user_id) values("100"),("8423105223472332825")`
   
   表设计定义user_id字段为字符类型，对20位的bigint (雪花算法生成的ID)查询不加引号，数据无法得取正确的返回
   
   执行操作：
   `select * from tb1 where user_id=100`
   正确返回
   
   执行操作：
   `select * from tb1 where user_id=8423105223472332825`
   无数据返回
   
   
   
   
   
   ### What You Expected?
   
   类型自动转换，支持bigint类型数据
   
   ### How to Reproduce?

   默认是转double来做匹配的，如果精度超了就会出现结果不准确的
