获取或设置包含执行 SQL 任务运行的 SQL 语句的源的名称。
public:
property System::String ^ SqlStatementSource { System::String ^ get(); void set(System::String ^ value); };
public string SqlStatementSource { get; set; }
member this.SqlStatementSource : string with get, set
Public Property SqlStatementSource As String
属性值
一个字符串,指示包含执行 SQL 任务运行的 SQL 语句的源的名称。
实现
示例
The following example creates an ExecuteSQLTask, then shows the default settings of the properties, including the SqlStatementSource, using the TaskHost. 然后,它设置除某些属性之外的值 SqlStatementSource ,以显示如何设置属性值。
using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Tasks.ExecuteSQLTask;
namespace Microsoft.SqlServer.SSIS.Samples
{
class Program
{
static void Main(string[] args)
{
Package pkg = new Package();
Executable exec1 = pkg.Executables.Add("STOCK:SQLTask");
TaskHost th = exec1 as TaskHost;
// List the default values of the Execute SQL task
// by using the Properties collection of the TaskHost.
Console.WriteLine("BypassPrepare {0}", th.Properties["BypassPrepare"].GetValue(th));
Console.WriteLine("CodePage {0}", th.Properties["CodePage"].GetValue(th));
Console.WriteLine("Connection {0}", th.Properties["Connection"].GetValue(th));
Console.WriteLine("ExecutionValue {0}", th.Properties["ExecutionValue"].GetValue(th));
Console.WriteLine("IsStoredProcedure {0}", th.Properties["IsStoredProcedure"].GetValue(th));
Console.WriteLine("ParameterBindings {0}", th.Properties["ParameterBindings"].GetValue(th));

Console.WriteLine("SqlStatementSourceType {0}", th.Properties["SqlStatementSourceType"].GetValue(th));
Console.WriteLine("TimeOut {0}", th.Properties["TimeOut"].GetValue(th));
Console.WriteLine("--------------------------");
// Show how to set a property by using the TaskHost properties.
Variable myVar = pkg.Variables.Add("myVar", false, "User", 100);
th.Properties["SqlStatementSourceType"].SetValue(th, SqlStatementSourceType.Variable);
th.Properties["SqlStatementSource"].SetValue(th, "myVar");
th.Properties["ResultSetType"].SetValue(th, ResultSetType.ResultSetType_XML);
Console.WriteLine("New value of Source and SourceType: {0}, {1}", th.Properties["SqlStatementSource"].GetValue(th), th.Properties["SqlStatementSourceType"].GetValue(th));
Console.WriteLine("New value of ResultSetType: {0}", th.Properties["ResultSetType"].GetValue(th), th.Properties["SqlStatementSourceType"].GetValue(th));
Console.WriteLine();
}
}

注解
源字符串可以是 SQL 语句本身、具有 SQL 语句的文件的连接管理器,也可以是包含 SQL 语句的变量的名称,具体取决于枚举的设置 SqlStatementSourceType 。
