### Which version of ShardingSphere did you use?
5.0.0-alpha
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
a sql submit to proxy which datagrip refresh databaes meta
```sql
/* ApplicationName=DataGrip 2020.2.3 */ select database(), schema(), left(user(),instr(concat(user(),'@'),'@')-1), @@version_comment
```
I execute the sql direct in datasource mysql,it look ok.
### Actual behavior
proxy cant parse the sql and print an error in console:
```log

### Reason analyze (If you can)
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
1. add a simple mysql datasource
2. start proxy server and connect port`3307` in datagrip
3. refresh database meta
4. or direct execute the sql:```sql
/* ApplicationName=DataGrip 2020.2.3 */ select database(), schema(), left(user(),instr(concat(user(),'@'),'@')-1), @@version_comment
```
