getStatementClass method is not supported!

Error message

getStatementClass method is not supported!

What it means

Sentinel UnsupportedOperationException in getStatementClass: the PreparedQuery lacks the analyzed statement object, so the JDBC statement class cannot be resolved — the query was prepared through a path that skips statement analysis.

Solutions

1. Use the PreparedQuery subclass that wraps the analyzed Statement
