Methods

CreateParameter()	Creates a parameter object that can be passed into the DeriveSchema(String, Int32, DataParameter[], Int32), DeriveSchema(String, Int32, DataParameter[], Int32), Execute(String, Int32, DataParameter[], Int32), or ExecuteWithoutResults(String, DataCommandType, IVsDataParameter[]) methods on a DataCommand instance.
DeriveParameters(String, DataCommandType, Int32)	Derives the parameters that can be specified for a given command.
DeriveParameters(String, DataCommandType)	Derives the parameters that can be specified for a given command.
DeriveParameters(String)	Derives the parameters that can be specified for a given command.
DeriveSchema(String, DataCommandType, IVsDataParameter[], Int32)	Derives the schema returned from a specified command. The schema indicates the layout of items and blocks in a data reader.
DeriveSchema(String, DataCommandType, IVsDataParameter[])	Derives the schema returned from a specified command. The schema indicates the layout of items and blocks in a data reader.
DeriveSchema(String, DataCommandType)	Derives the schema returned from a specified command. The schema indicates the layout of items and blocks in a data reader.
DeriveSchema(String)	Derives the schema returned from a specified command. The schema indicates the layout of items and blocks in a data reader.
Execute(String, DataCommandType, IVsDataParameter[], Int32)	Executes a specified command, optionally with parameters, and returns read-only results.
Execute(String, DataCommandType, IVsDataParameter[])	Executes a specified command, optionally with parameters, and returns read-only results.
Execute(String, DataCommandType)	Executes a specified command and returns read-only results.
Execute(String)	Executes a specified command and returns read-only results.
ExecuteWithoutResults(String, DataCommandType, IVsDataParameter[], Int32)	Executes a command, optionally with parameters, but does not request results, instead returning an integer indicating the outcome of the call.
ExecuteWithoutResults(String, DataCommandType, IVsDataParameter[])	Executes a command, optionally with parameters, but does not request results, instead returning an integer indicating the outcome of the call.
ExecuteWithoutResults(String, DataCommandType)	Executes a command but does not request results, instead returning an integer indicating the outcome of the call.
ExecuteWithoutResults(String)	Executes a command but does not request results, instead returning an integer indicating the outcome of the call.
OnSiteChanged(EventArgs)	Raises the SiteChanged event. (Inherited from DataSiteableObject<T>)
Prepare(String, DataCommandType, IVsDataParameter[], Int32)	Prepares the specified command on the data source to be executed; the command can then be executed multiple times, with varying parameters.
Prepare(String, DataCommandType, IVsDataParameter[])	Prepares the specified command on the data source to be executed; the command can then be executed multiple times, with varying parameters.
Prepare(String, DataCommandType)	Prepares the specified command on the data source to be executed; the command can then be executed multiple times, with varying parameters.
Prepare(String)	Prepares the specified command on the data source to be executed; the command can then be executed multiple times, with varying parameters.
