Spring JPA: Dynamic Schema|Table at runtime

named parameter bind only works on the where clause. what if you want different schema at runtime for the table part. such as

'select * from :tablename where ...'  

'update :tablename set ..."

You will find the above won't work in your @Query annotation

use EntityManager::createNativeQuery

You can get the single result, the first result, result lists or result stream.

use entityManager.createNativeQuery(sql).executeUpdate()

use executeUpdate to update or delete records in the table

Not allowed to create transaction on shared EntityManager

Caused by: java.lang.IllegalStateException: Not allowed to create transaction on shared EntityManager - use Spring transactions or EJB CMT instead

Please call joinTransaction before execute update sql
