付属するデータは、LINQ の場合は Include を使って取ってきてもよいのですが、外部キーの記述が結構面倒（標準にあっていないとうまくいかないことが多い）ので、あとから手作業でとってきています。多少検索スピードは落ちますが、ツール的にはこれで十分でしょう。まじめに作るときは SQL Server 等にデータを移行＆カラム名を連携しやすいように直します。. ACCESSの場合、テーブル単位ロックがかかっています。例えば、上記の場合、ACCESS 本体で「予約」テーブルを開いていると（デザインを開くも含む）と、EF Core 側で「予約」テーブルを開くことができなくてエラーになります。実際には、ロック解除待ちのタイムアウトになります。. なので、同時利用をしていると変なことになりそうなのですが、そこは運用次第ということで。ひとまず、ACCESS から SQL Server への移行ツールを作るときに EntityFrameworkCore.

Accessデータベースエンジン（ACEデータベースエンジン）とは – 意味をわかりやすく – IT用語辞典 e-Words – Connection String Parameters
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. To connect to this provider, set the Provider argument of the ConnectionString property to:. Reading the Provider property will return this string as well. Specifies the user name. If this keyword is not specified, the string, “admin”, is used by default. Specifies the user password. If this keyword is not specified, the empty string “” , is used by default. The OLE DB Provider for Microsoft Jet supports several provider-specific dynamic properties in addition to those defined by ADO.
As with all other Connection parameters, they can be set via the Connection object’s Properties collection or as part of the connection string. The following table lists these properties with the corresponding OLE DB property name in parentheses. Indicates an estimate of the amount of space, in bytes, that can be reclaimed by compacting the database. This value is only valid after a database connection has been established. Indicates the locking mode for this database. The first user to open the database determines the mode used while the database is open.
Indicates whether a compacted database should be encrypted. If this property is not set, the compacted database will be encrypted if the original database was also encrypted. Indicates the maximum length of time, in milliseconds, that Jet can delay asynchronous writes to disk when the database is opened exclusively.
This property is ignored unless Jet OLEDB:Flush Transaction Timeout is set to 0. Indicates the amount of time to wait before data stored in a cache for asynchronous writing is actually written to disk. This setting overrides the values for Jet OLEDB:Shared Async Delay and Jet OLEDB:Exclusive Async Delay. Indicates whether changes made in internal implicit transactions are written in synchronous or asynchronous mode.
Indicates the number of milliseconds to wait before attempting to acquire a lock after a previous attempt has failed. Indicates the maximum amount of memory, in kilobytes, Jet can use before it starts flushing changes to disk. Indicates the new password to be set for this database. The old password is stored in Jet OLEDB:Database Password. Indicates how many pages need to be locked within a transaction before Jet attempts to promote the lock to a table lock.
If this value is 0, then the lock is never promoted. Indicates the number of milliseconds Jet will wait before checking to see if its cache is out of date with the database file. Indicates the maximum amount of time, in milliseconds, Jet can delay asynchronous writes to disk when the database is opened in multi-user mode.
Indicates whether Jet writes data to disk synchronously or asynchronously when a transaction is committed. The Jet provider also supports several provider-specific Recordset and Command properties.
These properties are accessed and set through the Properties collection of the Recordset or Command object. The table lists the ADO property name and its corresponding OLE DB property name in parentheses. Indicates whether SQL bulk operations are transacted. Large bulk operations might fail when transacted, due to resource delays.
Indicates whether Jet should cache multiple rows when populating a recordset for remote row sources. Indicates the number of rows to cache when using remote data store row caching. This value is ignored unless Jet OLEDB:Enable Fat Cursors is True.
Indicates that Jet should pass the SQL text in a Command object to the back end unaltered. Indicates whether queries that do not return a Recordset are passed unaltered to the data source. Indicates the Jet connect string used to connect to a remote data store. This value is ignored unless Jet OLEDB:ODBC Pass-Through Statement is True. Indicates whether the command text should be interpreted as a stored query instead of an SQL command.
Indicates whether the Jet validation rules are evaluated when column data is set or when the changes are committed to the database. To open a database in read-only mode, set the Mode property on the ADO Connection object to adModeRead.
Command text in the Command object uses the Microsoft Jet SQL dialect. You can specify row-returning queries, action queries, and table names in the command text; however, stored procedures are not supported and should not be specified.
The Microsoft Jet database engine does not support dynamic cursors. Therefore, the OLE DB Provider for Microsoft Jet does not support the adLockDynamic cursor type. When a dynamic cursor is requested, the provider will return a keyset cursor and reset the CursorType property to indicate the type of Recordset returned. Further, if an updatable Recordset is requested LockType is adLockOptimistic , adLockBatchOptimistic , or adLockPessimistic the provider will also return a keyset cursor and reset the CursorType property.
The OLE DB Provider for Microsoft Jet inserts several dynamic properties into the Properties collection of the unopened Connection , Recordset , and Command objects. The tables below are a cross-index of the ADO and OLE DB names for each dynamic property. The OLE DB Programmer’s Reference refers to an ADO property name by the term, “Description.
Search for the OLE DB property name in the Index or see Appendix C: OLE DB Properties. The following properties are added to the Connection object’s Properties collection. The following properties are added to the Recordset object’s Properties collection. The following properties are added to the Command object’s Properties collection. For specific implementation details and functional information about the OLE DB Provider for Microsoft Jet, consult the OLE DB Provider for Microsoft Jet documentation in the MDAC SDK.
