Question

我一直在尝试执行原生UPDATE查询，但我一直收到ORA-01747错误。

public void editemployee (String id, String fname, String lname, String email, String phone,
        String hdate, String job, String salary, String comm, String dept) {
    StringBuilder editquery = new StringBuilder();
    editquery.append("UPDATE EMPLOYEES ");
    editquery.append("SET ");
    editquery.append("    FIRST_NAME = '"+fname+"', ");
    editquery.append("    LAST_NAME = '"+lname+"', ");
    editquery.append("    EMAIL = '"+email+"', ");
    editquery.append("    PHONE_NUMBER = '"+phone+"', ");
    editquery.append("    HIRE_DATE = TO_DATE('"+hdate+"', 'YYYY/MM/DD'), ");
    editquery.append("    SALARY = "+salary+", ");
    editquery.append("    COMMISSION_PCT = "+comm+", ");
    editquery.append("    JOB_ID = (SELECT JOB_ID FROM JOBS WHERE JOB_TITLE = '"+job+"'), ");
    editquery.append("    DEPARTMENT_ID = (SELECT DEPARTMENT_ID FROM DEPARTMENTS WHERE DEPARTMENT_NAME = '"+dept+"'), ");
    editquery.append("    MANAGER_ID = (SELECT MANAGER_ID FROM DEPARTMENTS WHERE DEPARTMENT_NAME = '"+dept+"') ");
    editquery.append("WHERE ");
    editquery.append("    EMPLOYEE_ID = "+id);

    JPA.em().createNativeQuery(editquery.toString()).executeUpdate();
}

这是针对培训活动的，因此我们需要使用StringBuilders来格式化我们的查询。

这是控制台错误日志的一部分。

至于数据库本身，列名是正确的，因为我能够使用这些列名执行其他本机查询。

public void addemployee (String fname, String lname, String email, String phone,
        String hdate, String job, String salary, String comm, String dept) {
    StringBuilder addquery = new StringBuilder();
    addquery.append("INSERT INTO ");
    addquery.append("    EMPLOYEES( ");
    addquery.append("        EMPLOYEE_ID, ");
    addquery.append("        FIRST_NAME, ");
    addquery.append("        LAST_NAME, ");
    addquery.append("        EMAIL, ");
    addquery.append("        PHONE_NUMBER, ");
    addquery.append("        HIRE_DATE, ");
    addquery.append("        SALARY, ");
    addquery.append("        COMMISSION_PCT, ");
    addquery.append("        JOB_ID, ");
    addquery.append("        DEPARTMENT_ID, ");
    addquery.append("        MANAGER_ID ) ");
    addquery.append("VALUES ( ");
    addquery.append("   (SELECT max(EMPLOYEE_ID) FROM EMPLOYEES) + 1, ");
    addquery.append("   '"+fname+"', ");
    addquery.append("   '"+lname+"', ");
    addquery.append("   '"+email+"', ");
    addquery.append("   '"+phone+"', ");
    addquery.append("   TO_DATE('"+hdate+"', 'YYYY/MM/DD'), ");
    addquery.append("   "+salary+", ");
    addquery.append("   "+comm+", ");
    addquery.append("   (SELECT JOB_ID FROM JOBS WHERE JOB_TITLE = '"+job+"'), ");
    addquery.append("   (SELECT DEPARTMENT_ID FROM DEPARTMENTS WHERE DEPARTMENT_NAME = '"+dept+"'), ");
    addquery.append("   (SELECT MANAGER_ID FROM DEPARTMENTS WHERE DEPARTMENT_NAME = '"+dept+"')) ");

    JPA.em().createNativeQuery(addquery.toString()).executeUpdate();
}

这个特殊的INSERT查询执行得很好，所以我不完全确定如何以及为什么我在UPDATE查询中获得ORA-01747。我还在我的Oracle SQL Developer上测试了这两个查询，他们都在执行。

我确实试图寻找类似的问题，但我看到的大部分内容都是针对INSERT查询的，这让我更加困惑为什么错误发生了。

ORA-01747使用Play框架
