JPA+HIBERNATE 執行非查詢語句報 Update/delete queries cannot be typed

java.lang.IllegalArgumentException:Update/delete queries cannot be typed

一：錯誤寫法

String hql =  " delete from T_ST_CircuitMeterInfo e where e.circuitID = ?";

Query query = em.createQuery(hql, T_ST_CircuitMeterInfo.class);
query.setParameter(1, circuitID);

int count =  query.executeUpdate();

 

二：正解

 

String hql =  " delete  from T_ST_CircuitMeterInfo e where e.circuitID = ?";

Query query = em.createQuery(hql);

query.setParameter(1, circuitID);
int count =  query.executeUpdate();

 

 

delete語句執行createQuery的時候，不能傳對象類。
