Public Function Prepare (command As String, commandType As DataCommandType, parameters As IVsDataParameter()) As String

Parameters

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.

Returns

String

An identifier of the prepared command that can later be passed to the Execute(String, DataCommandType, IVsDataParameter[], Int32) or ExecuteWithoutResults(String, DataCommandType, IVsDataParameter[], Int32) method by using the command type Prepared.

Implements

Prepare(String, DataCommandType, IVsDataParameter[])

Exceptions

ArgumentNullException

The command parameter is null.

ArgumentOutOfRangeException

The commandTimeout parameter is less than -1.

Prepare(String)

Prepares the specified command on the data source to be executed; the command can then be executed multiple times, with varying parameters.

Public Function Prepare (command As String) As String

Parameters

command

String

Returns

String

An identifier of the prepared command that can later be passed to the Execute(String, DataCommandType, IVsDataParameter[], Int32) or ExecuteWithoutResults(String, DataCommandType, IVsDataParameter[], Int32) method by using the command type Prepared.

Implements

Prepare(String)

Exceptions

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.

Returns

String

An identifier of the prepared command that can later be passed to the Execute(String, DataCommandType, IVsDataParameter[], Int32) or ExecuteWithoutResults(String, DataCommandType, IVsDataParameter[], Int32) method by using the command type Prepared.

Implements

Prepare(String, DataCommandType)

Exceptions

Public Overridable Function Prepare (command As String, commandType As DataCommandType, parameters As IVsDataParameter(), commandTimeout As Integer) As String

Parameters

command

String

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