Question

我正在开发一个使用带有存储过程的Oracle数据库的项目。我是用junit进行单元测试的。

我想要做的是使用嵌入式数据库来模拟Oracle数据库。但是，应用程序正在使用对存储过程的调用。存储过程包含两个变量并输出15。

使用对完整测试数据的表进行简单查询来模拟此存储过程会很简单。

哪些嵌入式数据库可用于模拟此功能？

web_services.search_registrants(
    cert_nbr_in => :cert_nbr_in,
    last_4_ssn_in => :last_4_ssn_in,
    status_out => :status_out,
    cert_nbr_out => :cert_nbr_out,
    last_4_ssn_out => :last_4_ssn_out,
    last_name_out => :last_name_out,
    first_name_out => :first_name_out,
    mid_name_out => :mid_name_out,
    email_addr_out => :email_addr_out,
    st_address1_out => :st_address1_out,
    st_address2_out => :st_address2_out,
    city_out => :city_out,
    state_out => :state_out,
    zip_code_out => :zip_code_out,
    home_phone_out => :home_phone_out,
    work_phone_out => :work_phone_out,
    cell_phone_out => :cell_phone_out);

这是java代码，可以很好地对抗Oracle。

 public Applicant find(String certNumber, String last4Ssn) {

    Connection conn = null;
    CallableStatement cs = null;
    Applicant applicant = null;

    try {
        try {
            conn = this.getConnection();

            cs = conn.prepareCall(
                    "{call NARS.web_services.search_registrants(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)}") ;

            cs.setString("CERT_NBR_IN", certNumber);
            cs.setString("LAST_4_SSN_IN", last4Ssn);
            cs.registerOutParameter("STATUS_OUT", Types.VARCHAR);
            cs.registerOutParameter("CERT_NBR_OUT", Types.VARCHAR);
            cs.registerOutParameter("LAST_4_SSN_OUT", Types.VARCHAR);
            cs.registerOutParameter("LAST_NAME_OUT", Types.VARCHAR);
            cs.registerOutParameter("FIRST_NAME_OUT", Types.VARCHAR);
            cs.registerOutParameter("MID_NAME_OUT", Types.VARCHAR);
            cs.registerOutParameter("EMAIL_ADDR_OUT", Types.VARCHAR);
            cs.registerOutParameter("ST_ADDRESS1_OUT", Types.VARCHAR);
            cs.registerOutParameter("ST_ADDRESS2_OUT", Types.VARCHAR);
            cs.registerOutParameter("CITY_OUT", Types.VARCHAR);
            cs.registerOutParameter("STATE_OUT", Types.VARCHAR);
            cs.registerOutParameter("ZIP_CODE_OUT", Types.VARCHAR);
            cs.registerOutParameter("HOME_PHONE_OUT", Types.VARCHAR);
            cs.registerOutParameter("WORK_PHONE_OUT", Types.VARCHAR);
            cs.registerOutParameter("CELL_PHONE_OUT", Types.VARCHAR);

            cs.execute();

            // 3 STATUS_OUT  OUT VARCHAR2 -- 0 = found, 
            // 1 = not found, 2 = expired certification, 3 = abuse
            String status = cs.getString("STATUS_OUT"); 
            System.out.println("status is: " + status);
            if(!status.equals("1")){

                System.out.println("certNumber " + cs.getString("CERT_NBR_OUT"));

                // Create new Applicant
                applicant = new Applicant(certNumber, last4Ssn);

                // 4 CERT_NBR_OUT        OUT VARCHAR2 -- 2 expired certification
                if(status.equals("2")){
                    applicant.setExpired(true);
                }
                if(status.equals("3")){
                    applicant.setAbuse(true);
                }

                applicant.setLastName(cs.getString("LAST_NAME_OUT"));
                applicant.setFirstName(cs.getString("FIRST_NAME_OUT"));
                applicant.setMidInit(cs.getString("MID_NAME_OUT"));
                applicant.setEmailAddress(cs.getString("EMAIL_ADDR_OUT"));
                applicant.setAddressLine1(cs.getString("ST_ADDRESS1_OUT"));
                applicant.setAddressLine2(cs.getString("ST_ADDRESS2_OUT"));
                applicant.setCity(cs.getString("CITY_OUT"));
                applicant.setState(cs.getString("STATE_OUT"));
                applicant.setZipCode(cs.getString("ZIP_CODE_OUT"));
                applicant.setHomePhone(cs.getString("HOME_PHONE_OUT"));
                applicant.setWorkPhone(cs.getString("WORK_PHONE_OUT"));
                applicant.setCellPhone(cs.getString("CELL_PHONE_OUT")); 
            }
        } catch (SQLException e) {
            e.printStackTrace();

        } finally {
            if(cs != null) cs.close();
            if(conn != null) conn.close();

        }
    } catch (SQLException e) {
        e.printStackTrace();
    }
    return applicant;
}

我使用HSQLDB解决了这个问题。我能够编写一个返回变量的存储过程。这真的很酷。以下是我的HSQLDB设置脚本的示例。

create table NARS_WEB_SERVICES.APPLICANTS (
  id INTEGER GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
  cert_nbr    VARCHAR(10),
  status      VARCHAR(1),
  last_name   VARCHAR(40),
  first_name  VARCHAR(40),
  mid_name    VARCHAR(30),
  gender_code VARCHAR(7),
  lst_4_ssn   VARCHAR(4),
  ssn         VARCHAR(9),
  addr_1      VARCHAR(30),
  addr_2      VARCHAR(30),
  city        VARCHAR(30),
  stat        VARCHAR(2),
  zip         VARCHAR(10),
  home_phone  VARCHAR(20),
  work_phone  VARCHAR(20),
  cell_phone  VARCHAR(20),
  email_addr  VARCHAR(50));

CREATE PROCEDURE NARS_WEB_SERVICES.SEARCH_REGISTRANTS 
     ( IN  CERT_NBR_IN     VARCHAR(30),
       IN  LAST_4_SSN_IN   VARCHAR(30),
       OUT STATUS_OUT      VARCHAR(30),
       OUT CERT_NBR_OUT    VARCHAR(30),
       OUT LAST_4_SSN_OUT  VARCHAR(30),
       OUT LAST_NAME_OUT   VARCHAR(30),
       OUT FIRST_NAME_OUT  VARCHAR(30),
       OUT MID_NAME_OUT    VARCHAR(30),
       OUT EMAIL_ADDR_OUT  VARCHAR(30),
       OUT ST_ADDRESS1_OUT VARCHAR(30),
       OUT ST_ADDRESS2_OUT VARCHAR(30),
       OUT CITY_OUT        VARCHAR(30),
       OUT STATE_OUT       VARCHAR(30),
       OUT ZIP_CODE_OUT    VARCHAR(30),
       OUT HOME_PHONE_OUT  VARCHAR(30),
       OUT WORK_PHONE_OUT  VARCHAR(30),
       OUT CELL_PHONE_OUT  VARCHAR(30) )
   READS SQL DATA
   BEGIN ATOMIC
     SELECT status, cert_nbr, last_name, first_name, mid_name, lst_4_ssn, 
            addr_1, addr_2, city, stat, zip, home_phone, work_phone, 
            cell_phone, email_addr
       INTO STATUS_OUT, CERT_NBR_OUT, LAST_NAME_OUT, FIRST_NAME_OUT, 
            MID_NAME_OUT, LAST_4_SSN_OUT, ST_ADDRESS1_OUT, ST_ADDRESS2_OUT, 
            CITY_OUT, STATE_OUT, ZIP_CODE_OUT, HOME_PHONE_OUT, WORK_PHONE_OUT, 
            CELL_PHONE_OUT, EMAIL_ADDR_OUT
       FROM NARS_WEB_SERVICES.APPLICANTS 
      WHERE cert_nbr = CERT_NBR_IN
         OR lst_4_ssn = LAST_4_SSN_IN;
   END
.;

就是这样！所以当然我将数据库设置为我的HSQLDB并对其进行测试。

测试数据库以与存储过程支持一起使用
