[GitHub] [shardingsphere] 15806659098 opened a new issue, #18763: when i execute select statement, it cause an error: This version of ShardingSphere-Proxy doesn't yet support this SQL. 'You have an error in your SQL syntax'
15806659098 opened a new issue, #18763:
URL: https://github.com/apache/shardingsphere/issues/18763
## Question
I have a problem when i execute select statement. I use ShardingSphere-Proxy, version is 5.1.2 and Mysql JDBC Driver is 8.0.28. The error is as follows. It similar to another problem #17888 . I think it may be caused by PrepareStatement.
` Error querying database. Cause: java.sql.SQLSyntaxErrorException: This version of ShardingSphere-Proxy doesn't yet support this SQL. 'You have an error in your SQL syntax'
The error may exist in file [D:\apache-tomcat-9.0.58\webapps\service_war\WEB-INF\classes\mapper\AcademicMapper.xml]
The error may involve com.dao.AcademicDao.queryAcademicByMingcheng-Inline
The error occurred while setting parameters
SQL: SELECT knowledgename,knowledgecontent FROM Academic WHERE knowledgename like "%"?"%"
Cause: java.sql.SQLSyntaxErrorException: This version of ShardingSphere-Proxy doesn't yet support this SQL. 'You have an error in your SQL syntax'; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: This version of ShardingSphere-Proxy doesn't yet support this SQL. 'You have an error in your SQL syntax'`
The select statement in my AcademicMapper.xml show in next picture.
It has no problem when i use MySql connected directly.
Thanks.
