The IVsDataCommand type exposes the following members.

Methods

  Name Description
Public method CreateParameter When implemented by a class, creates a parameter object that can be passed into one of the following methods: DeriveSchema, Execute, or ExecuteWithoutResults.
Public method DeriveParameters(String) When implemented by a class, derives the parameters that can be specified for a given command.
Public method DeriveParameters(String, DataCommandType) When implemented by a class, derives the parameters that can be specified for a given command.
Public method DeriveParameters(String, DataCommandType, Int32) When implemented by a class, derives the parameters that can be specified for a given command.
Public method DeriveSchema(String) When implemented by a class, derives the schema returned from a specified command. The schema indicates the layout of items and blocks in a data reader.
Public method DeriveSchema(String, DataCommandType) When implemented by a class, derives the schema returned from a specified command. The schema indicates the layout of items and blocks in a data reader.
Public method DeriveSchema(String, DataCommandType, array<IVsDataParameter[]) When implemented by a class, derives the schema returned from a specified command. The schema indicates the layout of items and blocks in a data reader.
Public method DeriveSchema(String, DataCommandType, array<IVsDataParameter[], Int32) When implemented by a class, derives the schema returned from a specified command. The schema indicates the layout of items and blocks in a data reader.
Public method Execute(String) When implemented by a class, executes a specified command and returns read-only results.
Public method Execute(String, DataCommandType) When implemented by a class, executes a specified command and returns read-only results.
Public method Execute(String, DataCommandType, array<IVsDataParameter[]) When implemented by a class, executes a specified command and returns read-only results.
Public method Execute(String, DataCommandType, array<IVsDataParameter[], Int32) When implemented by a class, executes a specified command and returns read-only results.
Public method ExecuteWithoutResults(String) When implemented by a class, executes a command but does not request results, instead returning an integer indicating the outcome of the call.
Public method ExecuteWithoutResults(String, DataCommandType) When implemented by a class, executes a command but does not request results, instead returning an integer indicating the outcome of the call.
Public method ExecuteWithoutResults(String, DataCommandType, array<IVsDataParameter[]) When implemented by a class, executes a command, optionally with parameters, but does not request results, instead returning an integer indicating the outcome of the call.
Public method ExecuteWithoutResults(String, DataCommandType, array<IVsDataParameter[], Int32) When implemented by a class, executes a command, optionally with parameters, but does not request results, instead returning an integer indicating the outcome of the call.
Public method Prepare(String) When implemented by a class, prepares the specified command on the data source to be executed; the command may then be executed multiple times, with varying parameters.
Public method Prepare(String, DataCommandType) When implemented by a class, prepares the specified command on the data source to be executed; the command may then be executed multiple times, with varying parameters.
Public method Prepare(String, DataCommandType, array<IVsDataParameter[]) When implemented by a class, prepares the specified command on the data source to be executed; the command may then be executed multiple times, with varying parameters.
Public method Prepare(String, DataCommandType, array<IVsDataParameter[], Int32) When implemented by a class, prepares the specified command on the data source to be executed; the command may then be executed multiple times, with varying parameters.
