Remarks
An ODBC connection can be stored in an Excel workbook. When Micrososft Excel opens the workbook, Excel creates an in-memory copy of the ODBC connection known as the ODBCConnection object.
An ODBCConnection object contains information related to the connection, such as the name of the server to connect to and the name of the objects to be opened on that server. Optionally, the ODBCConnection object may also include authentication credential information, or a command that is to be passed to the server and executed (for example, a SELECT statement to be executed by SQL Server).
Properties
| AlwaysUseConnectionFile |
True if the connection file is always used to establish connection to the data source. Read/write Boolean. |
| Application |
When used without an object qualifier, this property returns an _Application object that represents the Microsoft Office Excel application. When used with an object qualifier, this property returns an Application object that represents the creator of the specified object. Read-only. |

| CommandType |
Returns or sets one of the XlCmdType constants. Read/write XlCmdType. |
| Connection |
Returns or sets a string that contains ODBC settings that enable Microsoft Excel to connect to an ODBC data source. Read/write Object. |
| Creator |
Returns a constant in the XlCreator enumeration that indicates the application in which this object was created. Read-only. |
| EnableRefresh |
True if the connection can be refreshed by the user. The default value is True. Read/write Boolean. |

| Refreshing |
True if a background ODBC query is in progress for the specified ODBC connection. Read/write Boolean. |
| RefreshOnFileOpen |
True if the connection is automatically updated each time the workbook is opened. The default value is False. Read/write Boolean. |
| RefreshPeriod |
Returns or sets the number of minutes between refreshes. Read/write Integer. |
| RobustConnect |
Returns or sets how ODBC connection connects to its data source. Read/write XlRobustConnect. |

| ServerCredentialsMethod |
Returns or sets the type of credentials that should be used for server authentication. Read/write XlCredentialsMethod. |

Returns or sets a single sign-on application (SSO) identifier that is used to do a lookup in the SSO database for credentials. Read/write String. |
| SourceConnectionFile |
Returns or sets a String indicating the Microsoft Office Data Connection file or similar file that was used to create the connection. Read/write. |
| SourceData |
Returns the data source for the ODBC connection, as shown in the table. Read/write Object. |
