Extraction complète Test Lab

Bonjour,

Je n'arrive pas à obtenir le résultat d'une requête qui doit me renvoyer la liste de mes Test Lab.

ci-dessous le requête que j'ai faite. Elle est trop longue et fait planter HP-QC

SELECT
CF_ITEM_NAME as "Test Set Folder Name",
CY_CYCLE as "Test Set Name",
TS_NAME as "Test Case Name",
RN_STATUS as "Test Case Status",
ST_STEP_NAME as "Test Step Name",
ST_STATUS as "Test Step Status",
ST_DESCRIPTION as "Test Step Description",
ST_EXPECTED as "Test Step Expected Result",
ST_ACTUAL as "Test Step Actual Result",
RN_HOST as "Test Host Name",
RN_TESTER_NAME as "Tester Name",
ST_EXECUTION_DATE as "Test Step Execution Date",
ST_EXECUTION_TIME as "Test Step Execution Time"
FROM STEP a, TEST b, CYCLE c,RUN d,CYCL_FOLD e
where
a.ST_TEST_ID=b.TS_TEST_ID and
c.CY_CYCLE_ID=d.RN_CYCLE_ID and
d.RN_TEST_ID=b.TS_TEST_ID and
e.CF_ITEM_ID=c.CY_FOLDER_ID and
RN_HOST IS NOT NULL and
RN_TESTER_NAME IS NOT NULL


ORDER BY TS_NAME,RN_RUN_ID,ST_RUN_ID,ST_EXECUTION_DATE,ST_EXECUTION_TIME ASC

Vous parait-elle correcte ?
Merci pour votre aide.
