Question

Я работаю над отчетом журнала аудита и пользователями, которым нравится видеть исходные значения, которые были вставлены при создании записи, но, к сожалению, наши журналы аудита просто сохраняют запись как «Запись создана», но запись не делает содержат вставленные значения. Смотрите скриншот ниже:

Итак, все, что я изначально знаю, это то, что этот сертификат был вставлен 14.03.2009 - не идеально для того, что я пытаюсь сделать, но это то, что есть.

Меня интересует поиск вставленных значений для четырех столбцов из этой таблицы:

CertificationTypeID
CertificateIdentifier
StateCertificationIssued
DateCertificationIssued

Используя журналы аудита и таблицу сертификации, я могу воссоздать исходные значения, которые были при вставке записи, но каждый из столбцов таблицы сертификации представлен четырьмя столбцами в моем наборе записей журнала аудита:

OriginalValue
FieldName
ActionDate
RecordCreation

То, что я надеюсь сделать, - это развернуть (или перекрестно применить) столбцы, содержащие записи исходного значения, в строки, которые будут представлять каждый столбец, который был вставлен.

Например, первые четыре столбца для исходных записей - CT_OriginalValue, CT_FieldName, CT_ActionDate и CT_RecordCreation. Мне нужно, чтобы они превратились в четыре строки, которые заменили бы первую «Созданную запись», которая не содержала никакой информации.

В идеале - CT_FieldName и CT_RecordCreation должны быть конкатенированы и развернуты в строку и попадать в столбец ColumnName, CT_OriginalValue будет отключен в столбце NewValue, CT_ActionDate будет отключен для DateChanged.

Я пытался UNPIVOT, но мне не очень повезло, и я видел CROSS APPLY, использованный в этих ситуациях, но я не могу понять, как применить к этой ситуации.

Как насчет "UNPIVOT", который вам нужен, и "UNION ALL" с другими? И мне было плевать на порядок строк.
