Parameters
command
Type: System.StringThe command to be executed.
commandType
Type: System.Int32Format of the command string.
parameters
Type: array<Microsoft.VisualStudio.Data.DataParameter[]A list of parameters to pass with the command.
commandTimeout
Type: System.Int32Amount of time, in seconds, before which the command times out.
asyncCommandEvents
Type: Microsoft.VisualStudio.Data.DataAsyncCommandEventsThe object on which this method calls back as the command progresses.
Exceptions
| Exception | Condition |
|---|---|
| ArgumentNullException | The command or asyncCommandEvents are null. |
| ArgumentException | The commandType specifies an invalid type. |
| ArgumentOutOfRangeException | The commandTimeout is less than -1. |
| NotSupportedException | The provider does not support this method. |
Remarks
This method performs the same operation as the Execute method, but in an asynchronous manner.
If the value of the commandTimeout parameter is 0, there is no timeout (or, timeout is infinite); if the value is -1, the timeout period is that set by the data provider.
Note
Other exceptions that occur indicate that the parameter derivation failed for a provider-specified reason.
