ExecuteOptionEnum-Werte
| Constant | Value | Description |
|---|---|---|
| adOptionUnspecified | -1 | Unspecified command |
| adAsyncExecute | 16 | The command should execute asynchronously. Cannot be combined with the CommandTypeEnum value adCmdTableDirect |
| adAsyncFetch | 32 | The remaining rows after the initial quantity specified in the CacheSize property should be retrieved asynchronously |
| adAsyncFetchNonBlocking | 64 | The main thread never blocks while retrieving. If the requested row has not been retrieved, the current row automatically moves to the end of the file. If you open a Recordset from a Stream containing a persistently stored Recordset, adAsyncFetchNonBlocking will not have an effect; the operation will be synchronous and blocking. adAsynchFetchNonBlocking has no effect when the adCmdTableDirect option is used to open the Recordset |
| adExecuteRecord | 512 | The CommandText is a command or stored procedure that returns a single row which should be returned as a Record object |
