Sql Server Metadata Corruption After Importing Data From Excel File

In Microsoft SQL Server, you can import or export data through Import/Export Wizard. This wizard offers simplest way to create an Integration Services package, which copies data from a source to destination. The MS SQL Server Import/Export Wizard could copy data from and to a data source for which a native OLE DB provider or a managed .NET Framework data provider is available. Microsoft Excel is one such application. But sometimes, after importing data from Excel spreadsheet, the database may not be accessed. This behavior can occur due to corruption and lead to critical data loss situations. At this point, you need to opt for solutions to retrieve business-critical data from damaged database.

In a practical scenario, when you try to open a SQL Server database after importing data from an Excel spreadsheet that was originally created using data from SQL resultset, following errors may occur and prevent you to access the database:

The component has detected potential metadata corruption during validation.
Error at Update Counterparty Table with new counterparties [DTS.Pipeline]:
The package contains two objects with the duplicate name of ‘output column’

And

It may not be possible to recover to a valid state using a component-specific editor. Do you want to use the Advanced Editor dialog box for editing this component?

When this issue occurs, MS SQL Server database become inaccessible. In order to sort out this problem, you need to find out the cause of this issue and go for SQL Repair by resolving it.

Root of the issue

The metadata are used for easily accessing data from database. When they gets damaged, SQL Server can not find the required data and thus you come across data loss situations.

To retrieve data in such scenario, repair and restore damaged database through third party SQL Recovery applications. These software are particularly designed to thoroughly scan the affected database and retrieve all of its damaged and inaccessible objects such as stored procedures, triggers, tables, reports and forms. These tools are completely safe and easy to perform in all database corruption circumstances.

SQL Recovery is the best ever made and the most advanced application that repairs and restores all of the SQL Server database objects. It supports recovery from Microsoft SQL Server 2008, 2005 and 2000. This software is compatible with Microsoft Windows Vista, 2003, XP, 2000 and NT.
