- command
- String
A command to execute that is specific to a data source.
- commandType
- 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
- IVsDataParameter[]
An array of IVsDataParameter objects representing the command parameters for the specified command type.
- commandTimeout
- 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.
Returns
An IVsDataReader object, which provides a forward-only, read-only stream from the data source.
Implements
Exceptions
The command parameter is null.
The commandTimeout parameter is less than -1.
Applies to
Execute(String, DataCommandType, IVsDataParameter[])
Executes a specified command, optionally with parameters, and returns read-only results.
