Description
When running the complex query repeatedly in the stored procedure random garbage or empty results are returned on occasion.
Data dump with SP and test are contained in attachment. With the SP rewritten to store the output in a table the results that are correct and incorrect are as follows:
+-------------------+--------------+-----------------+------------+----------------------+-------------------------+-----------------------+--------------+-----------------+--------+----------+----------------+---------------------+
|
| customerReference | policyNumber | schemeReference | schemeName | applicationReference | modifiedCreatedDateTime | demandCreatedDateTime | countDemands | genericDemandId | status | isUrgent | reactivateDate | isBusinessException |
|
+-------------------+--------------+-----------------+------------+----------------------+-------------------------+-----------------------+--------------+-----------------+--------+----------+----------------+---------------------+
|
| reference1 | 1 | NULL | NULL | NULL | 2020-01-01 10:10:10 | 2020-01-01 10:10:10 | 1 | 1 | 1 | 0 | NULL | 0 |
|
+-------------------+--------------+-----------------+------------+----------------------+-------------------------+-----------------------+--------------+-----------------+--------+----------+----------------+---------------------+
|
Under high concurrency (should be a static result) from 10000 iterations the following rows were inserted:
mysql ds2 -e "select * from results where customerReference<>'reference1'"
