Topic Last Modified: 2010-02-11

Removes a data connection library from Excel Services Application.

Remove-SPExcelDataConnectionLibrary [-Identity] <SPExcelDCLPipeBind> -ExcelServiceApplication <SPExcelServiceApplicationPipeBind> [-AssignmentCollection <SPAssignmentCollection>] [-Confirm [<SwitchParameter>]] [-WhatIf [<SwitchParameter>]]

The Remove-SPExcelDataConnectionLibrary cmdlet removes a library from the Excel Services Application trusted data connection libraries list. Excel Services Application loads data connection files only if they are stored in a data connection library that is on the trusted data connection libraries list.

 

Parameter Required Type Description

Identity

Optional

Microsoft.Office.Excel.Server.Cmdlet.SPExcelDCLPipeBind

Specifies the data connection library to remove.

The type must be a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh; a valid name of a data connection library (for example, DataConnectionLib1); a valid URL, in the form http://server_name; or an instance of a valid SPExcelDCL object.

ExcelServiceApplication

Required

Microsoft.Office.Excel.Server.Cmdlet.SPExcelServiceApplicationPipeBind

Specifies the Excel Services Application Web service application that contains the SPExcelDataConnectionLibrary list object.

The type must be a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh; a valid name of an Excel Services Application Web service application in the farm (for example, MyExcelService1); or an instance of a valid SPExcelServiceApplication object.

AssignmentCollection

Optional

Microsoft.SharePoint.PowerShell.SPAssignmentCollection

Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

noteNote
When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.

Confirm

Optional

System.Management.Automation.SwitchParameter

Prompts you for confirmation before executing the command. For more information, type the following command: get-help about_commonparameters

WhatIf

Optional

System.Management.Automation.SwitchParameter

Displays a message that describes the effect of the command instead of executing the command. For more information, type the following command: get-help about_commonparameters
