QC数据库表结构
有时候QC的报表不能满足我们的要求，需要自己从QC的数据库中查询数据，放到Excel中进行统计并生成图表，因此有必要熟悉一下QC的表结构：
Requirement (REQ)
- Req ID (RQ_REQ_ID)
- Name (RQ_REQ_NAME)
- Description (RQ_REQ_COMMENT)
- Requirement Type (RQ_TYPE_ID)
- Is Folder (RQ_IS_FOLDER) – beware. This contains incorrect data (folders with value “N”)
- Req Father ID (RQ_FATHER_ID) e.g. the folder id that the requirement is in.
- Risk (RQ_USER_03)
Requirement Types (REQ_TYPE)
- Requirement Type ID (TPR_TYPE_ID) – is foreign key for REQ.RQ_TYPE_ID
- Requirement Type Name (TPR_NAME) – e.g. “Folder”, “Business”, “Functional” etc
Requirement Coverage (REQ_COVER) – maps requirements to test cases
- Requirement (RC_REQ_ID)
- Covering Entity ID (RC_ENTITY_ID)
- Coverage Type (RC_ENTITY_TYPE) – always seems to be “TEST”. Do not put this in a WHERE clause or you will filter out requirements that do not have an associated test case.
Test (TEST) – contains test cases
- Test ID (TS_TEST_ID)
- Test Name (TS_NAME)
- Execution Status (TS_EXEC_STATUS)
下面SQL脚本查出所有需求项：
-- This query shows all requirements in all folders.
SELECT
REQ.RQ_REQ_ID AS 'Requirement ID',
REQ.RQ_USER_01 AS 'Req ID Project', -- this has the original REQ ID from project doco
REQ.RQ_REQ_NAME AS 'Requirement Name',
REQ.RQ_REQ_COMMENT AS 'Requirement Description',
REQ_TYPE.TPR_NAME AS 'Requirement Type',
REQ.RQ_USER_03 AS 'Risk'
FROM
REQ
JOIN REQ_TYPE
ON REQ.RQ_TYPE_ID = REQ_TYPE.TPR_TYPE_ID -- join to get the name of the requirement type e.g "Folder"
WHERE
TPR_NAME != 'Folder' -- Only retrieve requirements of type "Business" or "Functional"
ORDER BY
RQ_REQ_ID
下面SQL脚本查出所有测试用例：
-- This query shows all test cases in all folders.
SELECT
TEST.TS_TEST_ID AS 'Test ID',
TEST.TS_NAME AS 'Test Name',
TEST.TS_EXEC_STATUS AS 'Execution Status'
FROM
TEST
ORDER BY
TEST.TS_TEST_ID
下面SQL脚本查出哪些有测试用例覆盖的需求项：
-- This query shows all requirements with any test cases that are mapped to the requirement.
-- If there are 2 test cases mapped to a requirement, then both will be included.
SELECT
REQ.RQ_REQ_ID AS 'Requirement ID',
REQ.RQ_USER_01 AS 'Req ID Project', -- this has the original REQ ID from project doco
REQ.RQ_REQ_NAME AS 'Requirement Name',
REQ.RQ_REQ_COMMENT AS 'Requirement Description',
REQ_TYPE.TPR_NAME AS 'Requirement Type',
REQ.RQ_USER_03 AS 'Risk',
TEST.TS_TEST_ID AS 'Test Case ID',
TEST.TS_NAME AS 'Test Case Name',
TEST.TS_EXEC_STATUS AS 'Execution Status'
FROM
REQ
LEFT JOIN
REQ_COVER ON REQ.RQ_REQ_ID = REQ_COVER.RC_REQ_ID -- join requirements to test cases (REQ to REQ_COVER)
LEFT JOIN
TEST ON REQ_COVER.RC_ENTITY_ID = TEST.TS_TEST_ID -- join requirements to test cases (REQ_COVER to TEST)
JOIN
REQ_TYPE ON REQ.RQ_TYPE_ID = REQ_TYPE.TPR_TYPE_ID -- join to get the name of the requirement type e.g "Folder"
WHERE
REQ_TYPE.TPR_NAME != 'Folder' -- Only retrieve requirements of type "Business" or "Functional"
ORDER BY
REQ.RQ_REQ_ID
