Microsoft Ole Db Provider For Odbc Drivers Download Install Update
Although increasingly more database vendors are implementing OLE DB interfaces, some data sources are not yet exposed this way. The provider is free-threaded and Unicode enabled. The provider supports transactions, although different DBMS engines offer different types of transaction support. For example, Microsoft Access supports nested transactions up to five levels deep. Reading the Provider property will return this string as well.
The provider does not support any specific connection parameters in addition to those defined by ADO. Because you can omit the Provider parameter, you can therefore compose an ADO connection string that is identical to an ODBC connection string for the same data source. Although a DSN definition already specifies a database, you can specify a database parameter in addition to a DSN to connect to a different database.
It is a good idea to always include the database parameter when you use a DSN. This will ensure that you connect to the proper database in the event that another user changed the default database parameter since you last checked the DSN definition.
The following table lists these properties with the corresponding OLE DB property name in parentheses. Indicates which numeric functions are supported by the ODBC driver. For a listing of function names and the associated values used in this bitmask, see Appendix E: Indicates which string functions are supported by the ODBC driver. Indicates which system functions are supported by the ODBC driver. Indicates which time and date functions are supported by the ODBC driver.
Indicates the method used to reduce potential problems caused by two users attempting to access the same data from the data source simultaneously. Indicates that after a new record has been inserted in a table, the last row in the table will be come the current row. Indicates whether the IRowsetChange interface provides extended information support.
How you use the Command object largely depends on the data source, and what type of query or command statement it will accept. ODBC provides a specific syntax for calling stored procedures. For the CommandText property of a Command object, the CommandText argument to the Execute method on a Connection object, or the Source argument to the Open method on a Recordset object, passes in a string with this syntax:.
The parameter references are optional and depend on the structure of the stored procedure. If you want to call a stored procedure that defines no parameters, your string would look like this:. If the stored procedure will return a value, the return value is treated as another parameter. If you have no query parameters but you do have a return value, your string would look like this:. The following tables list the standard ADO methods and properties available on a Recordset object opened with this provider.
For more detailed information about Recordset behavior for your provider configuration, run the Supports method and enumerate the Properties collection of the Recordset to determine whether provider-specific dynamic properties are present. 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.
Typical Connection String A typical connection string for this provider is: DSN Specifies the data source name. UID Specifies the user name. PWD Specifies the user password. For the CommandText property of a Command object, the CommandText argument to the Execute method on a Connection object, or the Source argument to the Open method on a Recordset object, passes in a string with this syntax: If you want to call a stored procedure that defines no parameters, your string would look like this: If you have no query parameters but you do have a return value, your string would look like this: Availability of standard ADO Recordset properties: Availability of standard ADO Recordset methods: Connection Dynamic Properties The following properties are added to the Connection object's Properties collection.
Can't use the Access ODBC driver or OLEDB provider outside Office Click-to-Run applications
To create a new DSN in Access, follow these steps: You must install an MSI installation of the Microsoft Access Database Engine from one of the following sources so that the calling application can locate the driver and provider. Microsoft Access Database Engine Redistributable https: Note If Office is already installed, side-by-side detection will prevent the installation from proceeding.
