Namespace:  Microsoft.VisualStudio.Data.Services.SupportEntities
Assembly:  Microsoft.VisualStudio.Data.Services (in Microsoft.VisualStudio.Data.Services.dll)

Syntax

Sub DeriveSchemaAsync ( _
    command As String, _
    commandType As DataCommandType, _
    parameters As IVsDataParameter(), _
    commandTimeout As Integer, _
    userState As Object _
)

Dim instance As IVsDataAsyncCommand
Dim command As String
Dim commandType As DataCommandType
Dim parameters As IVsDataParameter()
Dim commandTimeout As Integer
Dim userState As Object

instance.DeriveSchemaAsync(command, commandType, _
    parameters, commandTimeout, userState)

void DeriveSchemaAsync(
    string command,
    DataCommandType commandType,
    IVsDataParameter[] parameters,
    int commandTimeout,
    Object userState
)

void DeriveSchemaAsync(
    String^ command, 
    DataCommandType commandType, 
    array<IVsDataParameter^>^ parameters, 
    int commandTimeout, 
    Object^ userState
)

function DeriveSchemaAsync(
    command : String, 
    commandType : DataCommandType, 
    parameters : IVsDataParameter[], 
    commandTimeout : int, 
    userState : Object
)

Parameters

  Type: System.String

  The command for which the schema is derived.

• commandType
  Type: Microsoft.VisualStudio.Data.Services.SupportEntities.DataCommandType

  A value from the DataCommandType enumeration representing the command type for the indicated command, specifying how to interpret the contents of the command parameter.

• parameters
  Type: array<Microsoft.VisualStudio.Data.Services.SupportEntities.IVsDataParameter[]

  A list of parameters to pass with the command.

• commandTimeout
  Type: System.Int32

  Amount of time, in seconds, before which the command times out.

• userState
  Type: System.Object
