### Which version of ShardingSphere did you use?
4.1.1
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-JDBC
### Expected behavior
project works
### Actual behavior
SQLException:S0022 Unknown Column Id xxx
### Reason analyze (If you can)
error occurs in com.mysql.cj.jdbc.result.ResultSetImpl#findColumn(String) which is called by org.apache.shardingsphere.sql.parser.binder.metadata.column.TableMetaDataLoader#load(java.sql.Connection,String,String)
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
There are two tables in the same db, we assume that db name(schema name)was 'shard',one table name was 'table_1', another table name was 'shard.table_1', table 'table_1' had column 'table_1_column' while table 'shard.table_1' didn't have . when table 'shard.table_1' was scanned, after executing generated empty sql 'SELECT * FROM `shard.table_1` WHERE 1<>1' but colum name 'table_1_column' was in the result set of colums metadata, then this exception occured.
### Example codes for reproduce this issue (such as a github link).

it seems that my bad English led to your misunderstanding about what I have asked,I just care about when we can use a newer stable version than 5.0.0-alpha which have lower risk to be used in some important business situations.
