DAO Object
 
Sets or returns a value that indicates whether multiple transactiond that involve the same Microsoft Access database engine-connected ODBC data source are isolated (Microsoft Access workspaces only).
 

Syntax

expression .IsolateODBCTrans
expression A variable that represents a Workspace object.
 

Remarks

In some situations, you need to have multiple simultaneous transactions pending on the same ODBC connection. To do this, you need to open a separate Workspace for each transaction. Although each Workspace can have its own ODBC connection to the database, this slows system performance. Because transaction isolation isn't usually required, ODBC connections from multiple Workspace objects opened by the same user are shared by default.
 
Some ODBC servers, such as Microsoft SQL Server, don't allow simultaneous transactions on a single connection. If you need to have more than one transaction at a time pending against such a database, set the IsolateODBCTrans property to True on each Workspace as soon as you open it. This forces a separate ODBC connection for each Workspace.
