Class DBConnection

Specifies all properties associated with an ODBC or OLE DB external data connection.

Property Getters/Setters Summary
methodgetBackgroundRefresh()
method
           Indicates whether the connection can be refreshed in the background (asynchronously). true if preferred usage of the connection is to refresh asynchronously in the background; false if preferred usage of the connection is to refresh synchronously in the foreground.
methodgetCommand()
method
setCommand(value)
           The string containing the database command to pass to the data provider API that will interact with the external source in order to retrieve data
methodgetCommandType()
method
           Specifies the OLE DB command type. 1. Query specifies a cube name 2. Query specifies a SQL statement 3. Query specifies a table name 4. Query specifies that default information has been given, and it is up to the provider how to interpret. 5. Query is against a web based List Data Provider. The value of the property is OLEDBCommandType integer constant.
methodgetConnectionDescription()
method
           Specifies the user description for this connection
methodgetConnectionId()
Specifies The unique identifier of this connection.
methodgetConnectionInfo()
method
           The connection information string is used to make contact with an OLE DB or ODBC data source.
methodgetCredentials()
method
           Specifies the authentication method to be used when establishing (or re-establishing) the connection. The value of the property is CredentialsMethodType integer constant.
methodgetCredentialsMethodType()
method
           Specifies the authentication method to be used when establishing (or re-establishing) the connection. The value of the property is CredentialsMethodType integer constant.
methodgetId()
Gets the id of the connection.
methodisDeleted()
method
setDeleted(value)
           Indicates whether the associated workbook connection has been deleted. true if the connection has been deleted; otherwise, false.
methodisNew()
method
setNew(value)
           True if the connection has not been refreshed for the first time; otherwise, false. This state can happen when the user saves the file before a query has finished returning.
methodgetKeepAlive()
method
           True when the spreadsheet application should make efforts to keep the connection open. When false, the application should close the connection after retrieving the information.
methodgetName()
method
setName(value)
           Specifies the name of the connection. Each connection must have a unique name.
methodgetOdcFile()
method
setOdcFile(value)
           Specifies the full path to external connection file from which this connection was created. If a connection fails during an attempt to refresh data, and reconnectionMethod=1, then the spreadsheet application will try again using information from the external connection file instead of the connection object embedded within the workbook.
methodgetOnlyUseConnectionFile()
method
           Indicates whether the spreadsheet application should always and only use the connection information in the external connection file indicated by the odcFile attribute when the connection is refreshed. If false, then the spreadsheet application should follow the procedure indicated by the reconnectionMethod attribute
methodgetParameters()
Gets ConnectionParameterCollection for an ODBC or web query.
methodgetPowerQueryFormula()
Gets the definition of power query formula.
methodgetReconnectionMethod()
method
           Specifies what the spreadsheet application should do when a connection fails. The default value is ReConnectionMethodType.Required. The value of the property is ReConnectionMethodType integer constant.
methodgetReconnectionMethodType()
method
           Specifies what the spreadsheet application should do when a connection fails. The default value is ReConnectionMethodType.Required. The value of the property is ReConnectionMethodType integer constant.
methodgetRefreshInternal()
method
           Specifies the number of minutes between automatic refreshes of the connection.
methodgetRefreshOnLoad()
method
           True if this connection should be refreshed when opening the file; otherwise, false.
methodgetSaveData()
method
           True if the external data fetched over the connection to populate a table is to be saved with the workbook; otherwise, false.
methodgetSavePassword()
method
           True if the password is to be saved as part of the connection string; otherwise, False.
methodgetSeverCommand()
method
           Specifies a second command text string that is persisted when PivotTable server-based page fields are in use. For ODBC connections, serverCommand is usually a broader query than command (no WHERE clause is present in the former). Based on these 2 commands(Command and ServerCommand), parameter UI can be populated and parameterized queries can be constructed
methodgetSourceFile()
method
           Used when the external data source is file-based. When a connection to such a data source fails, the spreadsheet application attempts to connect directly to this file. May be expressed in URI or system-specific file path notation.
methodgetSSOId()
method
setSSOId(value)
           Identifier for Single Sign On (SSO) used for authentication between an intermediate spreadsheetML server and the external data source.
methodgetType()
Gets or Sets the external connection DataSource type.
