Parameters

command
Type: System.String

A command to execute that is specific to a data source.

commandType
Type: Microsoft.VisualStudio.Data.Services.SupportEntities.DataCommandType

The type of the command that specifies how to interpret the contents of the command parameter. The command type could either be a value from the DataCommandType enumeration or a custom command type defined by a provider, which can be passed in by forcing a cast from an integer to the DataCommandType enumeration.

parameters
Type: []

An array of IVsDataParameter objects representing the command parameters for the specified command type.

commandTimeout
Type: System.Int32

The length of time, in seconds, to block the client before canceling the execution and returning to the caller. A value of 0 indicates infinite time-out; a value of -1 indicates a provider default.

Return Value

Type: System.Int32

A DDEX provider–specific integer status code.

Implements

IVsDataCommand.ExecuteWithoutResults(String, DataCommandType, [], Int32)

Exceptions

Exception	Condition
ArgumentNullException	The command parameter is a null reference (Nothing in Visual Basic).
ArgumentOutOfRangeException	The commandTimeout parameter is less than -1.

Remarks

In many cases, the outcome of the call to this method will indicate the number of rows affected.

You can still set out and return value parameters by using this call. They are not considered part of the results.

注意

Other exceptions that occur indicate that the execution failed for a provider-specified reason.
