UnsupportedOperationException

Error message

UnsupportedOperationException

What it means

PreparedStatementParameterLogger is a JDBC PreparedStatement wrapper that only logs SQL parameters; it delegates the actual execution to an underlying statement. Statements that do not make sense for a prepared statement being parameter-logged — like getGeneratedKeys() — are hardcoded to throw UnsupportedOperationException.

Solutions

1. Obtain generated keys from the unwrapped, original PreparedStatement (unwrap or keep a reference before wrapping).
2. Restructure the code so key retrieval does not pass through the parameter-logging wrapper.
3. If this blocks a use case, fall back to selecting the generated key with an explicit query (e.g. LAST_INSERT_ID) rather than getGeneratedKeys().

Example fix

// before
ResultSet keys = loggingStatement.getGeneratedKeys();
// after
PreparedStatement raw = loggingStatement.unwrap(PreparedStatement.class);
ResultSet keys = raw.getGeneratedKeys();

try {
    keys = stmt.getGeneratedKeys();
} catch (UnsupportedOperationException e) {
    PreparedStatement raw = stmt.unwrap(PreparedStatement.class);
    keys = raw.getGeneratedKeys();
}

When it happens

Trigger: Calling getGeneratedKeys() on a PreparedStatement wrapped by the parameter logger, typically when using IDENTITY/auto-generated key retrieval through code instrumented by this plugin.

Common situations: MyBatis/DAO code using useGeneratedKeys or Statement.RETURN_GENERATED_KEYS while the Pinpoint mybatis plugin wraps the statement for logging; retrieving auto-generated IDs inside an instrumented path.

Understand the failure class

Background: UnsupportedOperationException and "is not supported" errors: when a library deliberately refuses a call — this error's family across 30 libraries.
