I'm having difficulty trying to get the last date of an activity compared to a date in a other table.
I have the following tables:
System
System
Test
Timestamp
Test_system_A
Test_cycle_1
2018-01-01 12:08:09
Test_system_A
Test_cycle_4
2018-01-03 11:08:49
Test_system_B
Test_cycle_3
2018-01-02 16:16:09
Test_system_A
Test_cycle_2
2018-01-05 08:08:19
Test_system_A
Test_cycle_9
2018-01-06 20:18:09
Config
System
Configuration
Timestamp
Test_system_A
config1a
2018-01-01 08:08:09
Test_system_A
config1b
2018-01-05 20:08:09
Test_system_B
config1a
2018-01-01 10:08:09
The report should show the number of test cycles have been performed on which system and configuration and when the last test cycle has been performed.
