## Bug Report
mysql> ADD RESOURCE ds01 (
-> host=127.0.0.1,
-> port=13306,
-> db="my_database",
-> user="root",
-> password="my_root_password"
-> )

ERROR 12000 (42000): You have an error in your SQL syntax: ADD RESOURCE ds01
(
host=127.0.0.1,
port=13306,
db="my_database",
user="root",
password="my_root_password"
), no viable alternative at input 'ADD' at line 1, position 0, near
[@0,0:2='ADD',<78>,1:0]
### Which version of ShardingSphere did you use?
```
mysql> select version();
+-----------------------------------+
| version() |
+-----------------------------------+
| 5.7.22-ShardingSphere-Proxy 5.2.1 |
+-----------------------------------+
1 row in set (0.04 sec)
```
### mysql client version
```mysql --version
mysql Ver 8.0.31-0ubuntu0.20.04.1 for Linux on x86_64 ((Ubuntu))
```
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
add resource sucessed;
### Actual behavior
no viable alternative at input 'ADD' at line 1, position 0, near
[@0,0:2='ADD',<78>,1:0]
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule
```server.yaml
authority:
users:
- user: root
password: root
- user: sharding
password: sharding
privilege:
type: ALL_PERMITTED
rules:
- !TRANSACTION
defaultType: XA
providerType: Atomikos
- !SQL_PARSER
sqlCommentParseEnabled: true
props:
max-connections-size-per-query: 1
kernel-executor-size: 16 # Infinite by default.
proxy-frontend-flush-threshold: 128 # The default value is 128.
proxy-hint-enabled: true
sql-show: false
check-table-metadata-enabled: false
# Proxy backend query fetch size. A larger value may increase the memory
usage of ShardingSphere Proxy.
# The default value is -1, which means set the minimum value for different
JDBC drivers.
proxy-backend-query-fetch-size: -1
proxy-frontend-executor-size: 0 # Proxy frontend executor size. The
default value is 0, which means let Netty decide.
# Available options of proxy backend executor suitable: OLAP(default),
OLTP. The OLTP option may reduce time cost of writing packets to client, but it
may increase the latency of SQL execution
# if client connections are more than proxy-frontend-netty-executor-size,
especially executing slow SQL.
proxy-backend-executor-suitable: OLAP
```
``` start proxy
shardingsphere-proxy/bin/start.sh
```
``` connect to server
mysql -h127.0.0.1 -P3307 -uroot -proot
```
```
ADD RESOURCE ds01 (
host=119.23.110.179,

password="my_root_password"
);
