Valeur de propriété

true if the task bypasses preparation of the SQL command; false if the RDBMS prepares the statement before execution.

Notes

Texte mis à jour :5 décembre 2005

This property provides the ability to bypass the prepare command for OLE DB connections, because prepare does not support some Transact-SQL keywords, such as restore. This property, when set to true, lets the command run without preparing.

Exemple

The following example creates an ExecuteSQLTask, then shows the default settings of the properties, including the BypassPrepare, using the TaskHost. It then sets the value of some properties to show how to set property values.

using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Tasks.ExecuteSQLTask;

            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));
