[Option] /SQ[L] package_path [Description] 
Loads a package that is stored in SQL Server. The package_path argument specifies the name of the package to retrieve. If folders are included in the path, they are terminated with backslashes ("\"). The package_path value can be quoted. If the path or file name specified in the package_path argument contains a space, you must put quotation marks around the package_path argument. You can use the /User, /Password, and /Server options together with the /SQL option. If you omit the /User option, Windows Authentication is used to access the package. If you use the /User option, the /User login name specified is associated with SQL Server Authentication. The /Password option is used only together with the /User option. If you use the /Password option, the package is accessed with the user name and password information provided. If you omit the /Password option, a blank password is used. Security Note When possible, use Windows Authentication. If the /Server option is omitted, the default local instance of SQL Server is assumed. The /SQL option cannot be used together with the /DTS or /File option. If multiple options are specified, dtexec fails.
