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

Notas
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.
Ejemplos
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.
