【中文标题】测试数据库与存储过程支持一起使用【英文标题】：Test database to use with a stored procedure support 【发布时间】：2012-01-11 23:09:29 【问题描述】：我正在处理一个使用带有存储过程的 Oracle 数据库的项目。我正在使用 junit 进行单元测试。
我想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。存储过程接受两个变量和输出 15.
用一个简单的查询来模拟这个存储过程是很简单的，它对一个满是测试数据的表进行了查询。
有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，对 Oracle 运行良好。
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;

【参考方案2】：我通过使用 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。这是我的 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 并针对它进行了测试。
