The IVsDataCommand type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
.gif "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. |
|
DeriveParameters(String) | When implemented by a class, derives the parameters that can be specified for a given command. |
|
DeriveParameters(String, DataCommandType) | When implemented by a class, derives the parameters that can be specified for a given command. |
|
DeriveParameters(String, DataCommandType, Int32) | When implemented by a class, derives the parameters that can be specified for a given command. |
|
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. |
|
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. |
|
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. |
|
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. |
|
Execute(String) | When implemented by a class, executes a specified command and returns read-only results. |
|
Execute(String, DataCommandType) | When implemented by a class, executes a specified command and returns read-only results. |
|
Execute(String, DataCommandType, array<IVsDataParameter[]) | When implemented by a class, executes a specified command and returns read-only results. |
|
Execute(String, DataCommandType, array<IVsDataParameter[], Int32) | When implemented by a class, executes a specified command and returns read-only results. |
|
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. |
|
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. |
|
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. |
|
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. |
|
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. |
|
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. |
|
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. |
|
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. |
