Reason analyze (If you can)

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).

@wszpwsren Using reserved words as column names is not syntactically legal, is it supported directly on mysql?

terrymanu commented 2 years ago

No response for long time, I just close it

lzbjut commented 3 months ago

is this problem fixed？ when query use jdbc or direct connect to mysql, select ud.describe from user_debt ud where brand_id = ? can query select describe from user_debt where brand_id = ? can not but shardingsphere cannot do quey on both these quey
