Awaiting investigation, as the following unit test executes normally, which
means there is a logic execution error.
```java
@Test
public void assertGetGeneratedKeys() throws SQLException {
Connection conn =
DriverManager.getConnection("jdbc:h2:mem:test;DATABASE_TO_UPPER=false;MODE=MySQL",
"sa", "");
conn.createStatement().execute("CREATE TABLE IF NOT EXISTS t_config (id
INT NOT NULL AUTO_INCREMENT, status VARCHAR(45) NULL, PRIMARY KEY (id));");
try (
PreparedStatement preparedStatement =
conn.prepareStatement("INSERT INTO t_config(status) VALUES(?);",
Statement.RETURN_GENERATED_KEYS)) {
preparedStatement.setString(1, "OK");
preparedStatement.executeUpdate();
ResultSet generatedKeys = preparedStatement.getGeneratedKeys();
assertTrue(generatedKeys.next());
int columnCount = generatedKeys.getMetaData().getColumnCount();
for (int index = 0; index < columnCount; index++) {
assertNotNull(generatedKeys.getObject(index + 1));
assertNotNull(generatedKeys.getMetaData().getColumnLabel(index +
1));
assertNotNull(generatedKeys.getMetaData().getColumnName(index +
1));
}
assertFalse(generatedKeys.next());
}
conn.close();
}
```
