[GitHub] [shardingsphere] ReyYang opened a new issue #14604: "Data truncated for column" error occurs during the migration of the year type field
ReyYang opened a new issue #14604:
URL: https://github.com/apache/shardingsphere/issues/14604
"Data truncated for column" error occurs during the migration of the year type field
### Which version of ShardingSphere did you use?
master branch
MySQL 5.6,5.7
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Scaling
### Expected behavior
Successful migration
### Actual behavior
"Data truncated for column" error occurs during the migration of the year type field
### Reason analyze (If you can)
The year data type in MySQL can be expressed as either Date or Integer
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
```sql
-- create table
create table table_date
(
id bigint
primary key,
shard_id bigint not null,
t_date date null,
t_time time null,
t_datetime datetime null,
t_timestamp timestamp null,
t_year year null
);
-- insert datas
insert into table_date (id, shard_id, t_date, t_time,
t_datetime, t_timestamp, t_year)
VALUES (1, 1, '1997-10-13', '13:01:45', '1997-10-13 13:01:45', '1997-10-13 13:01:45', 1997),
