속성 값

true if the VSA script is compiled when the package is saved; otherwise, false. The default value is true.

주의

VSA scripts must be compiled before the package runs. The Script task includes the option to pre-compile script into binary code when the package is saved. When script is precompiled, the language engine is not loaded at run time and the package runs more quickly; however, compiled binary files consume significant disk space. Script that is not precompiled is compiled at run time, which slows package execution but consumes less disk space. When storing large packages is not a problem, you should pre-compile your VSA scripts.

예

The following code sample, implemented in a console application, adds a ScriptTask to the package and displays the default values of some of its properties, including the PreCompile property.

using System;
using Microsoft.SqlServer.Dts.Runtime;

namespace ScriptTaskCS
{
  class Program
  {
    static void Main(string[] args)
    {
      Package pkg = new Package();
      string newLine = System.Environment.NewLine;

      Executable exe = pkg.Executables.Add("STOCK:ScriptTask");
      TaskHost thTask = (TaskHost)exe;

      string taskInfo;
      taskInfo = 
        "Project name: " + 
        thTask.Properties["VsaProjectName"].GetValue(thTask) + newLine + 
        "Entry point: " + 
        thTask.Properties["EntryPoint"].GetValue(thTask) + newLine + 
        "Script Language: " + 
        thTask.Properties["ScriptLanguage"].GetValue(thTask) + newLine + 
        "Precompiled?: " + 
        thTask.Properties["PreCompile"].GetValue(thTask) + newLine + 
        "ReadOnlyVariables: " + 
        thTask.Properties["ReadOnlyVariables"].GetValue(thTask) + newLine + 
        "ReadWriteVariables: " + 
        thTask.Properties["ReadWriteVariables"].GetValue(thTask);

      Console.WriteLine(taskInfo);
      Console.Read();
    }
  }
}

Imports Microsoft.SqlServer.Dts.Runtime

Module Module1

  Sub Main()

    Dim pkg As New Package
    Dim newLine As String = System.Environment.NewLine

    Dim exe As Executable = pkg.Executables.Add("STOCK:ScriptTask")
    Dim thTask As TaskHost = CType(exe, TaskHost)

    Dim taskInfo As String
    taskInfo = "Project name: " & _
      thTask.Properties("VsaProjectName").GetValue(thTask) & newLine & _
      "Entry point: " & _
      thTask.Properties("EntryPoint").GetValue(thTask) & newLine & _
      "Script Language: " & _
      thTask.Properties("ScriptLanguage").GetValue(thTask) & newLine & _
      "Precompiled?: " & _
      thTask.Properties("PreCompile").GetValue(thTask) & newLine & _
      "ReadOnlyVariables: " & _
      thTask.Properties("ReadOnlyVariables").GetValue(thTask) & newLine & _
      "ReadWriteVariables: " & _
      thTask.Properties("ReadWriteVariables").GetValue(thTask)

    Console.WriteLine(taskInfo)
    Console.Read()

  End Sub

End Module
