db-task-plsql-cern-ld's Issues
t7: logging
Make sure that the actions are logged into the log_messages table even if the data manipulation fails and the transaction needs to be rolled back.
t6: copy_settings exceptions
Implement error handling for the procedure "copy_settings".
t5: create packages
Transform individual functions and procedures into package(s).
t8: new procedure
Implement a routine to query all settings for a given parameter/process, regardless of the underlying value type. Take into account that the volume of data returned can be very large.
t4: is_active constraint
Introduce a constraint such that only one setting per parameter/process combo can be active (is_active = 'Y'), with no limitation on the number of non-active settings.
