備註
SQL Server calls this method when any of the following parameters change on an open connection:
ServerName
SqlConnection
UserName
Password and SecurePassword
UseIntegratedSecurity
DatabaseName
ConnectionTimeout
In Integration Services, changes to the following parameters also initiate a call to this method:
ApplicationName
WorkstationID
In SQL Server Compact 3.5, changes to the following parameters also initiate a call to this method:
MaxDatabaseSize
DefaultLockEscalation
Standard SQL Server connection classes, such as SqlConnectionInfo, provide a default implementation of this method, which then rebuilds the connection string. If you are creating your own connection class based on ConnectionInfoBase, you must override this method and implement your own logic for handling connection parameter changes.
