```
### Reason analyze (If you can)
1. database: set column col1 type to varchar(40);
2. jdbc connector: column co1 jdbctype is Clob.class
3. getValue fail. throw new SQLFeatureNotSupportedException.
class: `org.apache.shardingsphere.core.merge.dql.common.MemoryMergedResult.getValue`
```
@Override
public final Object getValue(final String columnLabel, final Class<?> type) throws SQLException {
if (Blob.class == type || Clob.class == type || Reader.class == type || InputStream.class == type || SQLXML.class == type) {
throw new SQLFeatureNotSupportedException();
}
Object result = currentResultSetRow.getCell(labelAndIndexMap.containsKey(columnLabel) ? labelAndIndexMap.get(columnLabel) : labelAndIndexMap.get(SQLUtil.getExactlyValue(columnLabel)));
wasNull = null == result;
return result;
}
```
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
### Example codes for reproduce this issue (such as a github link).
