BypassPrepare 属性

Gets or sets a Boolean that indicates whether the Execute SQL task skips preparation of the statement when sending the SQL statement to the relational database management system (RDBMS).

命名空间:  Microsoft.SqlServer.Dts.Tasks.ExecuteSQLTask
程序集:  Microsoft.SqlServer.SQLTask(在 Microsoft.SqlServer.SQLTask.dll 中)

语法

声明
Public Property BypassPrepare As Boolean
    Get
    Set
用法
Dim instance As ExecuteSQLTask
Dim value As Boolean

value = instance.BypassPrepare

instance.BypassPrepare = value
public bool BypassPrepare { get; set; }
public:
virtual property bool BypassPrepare {
    bool get () sealed;
    void set (bool value) sealed;
}
abstract BypassPrepare : bool with get, set
override BypassPrepare : bool with get, set
final function get BypassPrepare () : boolean
final function set BypassPrepare (value : boolean)

属性值

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

实现

IDTSExecuteSQL. . :: . .BypassPrepare

注释

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.

示例

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.

            // List the default values of the Execute SQL task
