Решение только для текстовых файлов (включая запросы, таблицы и отношения)
Я изменил пару сценариев Оливера, чтобы они экспортировали / импортировали отношения, таблицы и запросы в дополнение к модулям, классам, формам и макросам. Все сохраняется в виде текстовых файлов, поэтому файл базы данных не создан для хранения вместе с текстовыми файлами в системе управления версиями.
Экспорт в текстовые файлы (degpose.vbs)
' Usage:
' cscript decompose.vbs <input file> <path>
' Converts all modules, classes, forms and macros from an Access Project file (.adp) <input file> to
' text and saves the results in separate files to <path>. Requires Microsoft Access.

Вы можете выполнить этот скрипт, вызвав cscript decompose.vbs <path to file to decompose> <folder to store text files>. Если вы пропустите второй параметр, он создаст папку «Source», в которой находится база данных. Обратите внимание, что папка назначения будет удалена, если она уже существует.

Импорт данных из текстового файла
Заменить строку 14: const acStructureOnly = 0 на const acStructureOnly = 1. Это будет работать, только если вы включили данные в экспортированную таблицу.
Вещи, которые не охвачены
- Я проверял это только с файлами .accdb, так что с чем-то еще могут быть некоторые ошибки.
- Настройки не экспортируются, я бы порекомендовал создать макрос, который будет применять настройки при запуске базы данных.
- Некоторые неизвестные запросы иногда экспортируются, которым предшествует '~'. Я не знаю, нужны ли они.
Одним из моих других ресурсов при работе над этим сценарием был этот ответ , который помог мне понять, как экспортировать отношения.
