Table name is keyword error

Bug Report

For English only, other languages will not accept.

When I use ShardingSphere-proxy for data migration, when the table name is a keyword, such as user or unit, when I use the command:

"MIGRATE TABLE ds_0.user INTO user"

The migration task fails to be created with the following error: ERROR 1064 (42000): You have an error in your SQL syntax: no viable alternative at input 'MIGRATE' near '[@0,0:6='MIGRATE',<449>,1:0]' at line 1.

When I changed it to

“MIGRATE TABLE ds_0.user INTO user”

The task can be created successfully, but the following error message is displayed in the log:

Can not get meta data for table 'user' when split by range.

This seems to be a bug, can you fix this problem?

Hi team,

I noticed the issue regarding migration failure when using reserved keywords like user or unit as table names. This seems to be related to syntax handling and metadata fetching in ShardingSphere-Proxy during migration tasks.

I'd like to contribute by investigating and resolving this issue. Could you please assign it to me? I’ll ensure to follow the contribution guidelines and provide a detailed solution.

Looking forward to your approval!
