Listing all Data Sources and their Dependencies (r

Question

I am new to SQL Server, and I am sorry if there is an obvious solution to my question but I can't seem to find it.

I am looking to generate a report (or list) of all the data sources and their individual dependencies on an SQL Server 2008 R2 (reporting server).

I know that I can access each individual data source to get a list of all the items that are dependent on it. I have done this in the past but it is time consuming.

Is there a way to get a report that would display all the data sources and their dependent items?

Thanks in advance,

Marwan

This query should be run against the ReportServer database

SELECT
    DS.Name AS DatasourceName,
    C.Name AS DependentItemName, 
    C.Path AS DependentItemPath
FROM
    ReportServer.dbo.Catalog AS C 
        INNER JOIN
    ReportServer.dbo.Users AS CU
        ON C.CreatedByID = CU.UserID
        INNER JOIN
    ReportServer.dbo.Users AS MU
        ON C.ModifiedByID = MU.UserID
        LEFT OUTER JOIN
    ReportServer.dbo.SecData AS SD
        ON C.PolicyID = SD.PolicyID AND SD.AuthType = 1
        INNER JOIN
    ReportServer.dbo.DataSource AS DS
        ON C.ItemID = DS.ItemID
WHERE
    DS.Name IS NOT NULL
ORDER BY
    DS.Name;

The dependent items page in Report Manager executes the dbo.FindItemsByDataSource stored procedure, supplying these parameters: ItemID = <data source item ID> and AuthType = 1. The above query is a hacked version of the query used by this stored procedure to remove the data source specific ID. This allows dependent items to be returned for all data sources. I removed the data sources themselves from the results with DS.Name IS NOT NULL

You might also consider using Powershell:

    $dependentReports = $dependencies.Count

    if($dependencies.Count -eq 0){
        [string]$itemName = $item.Path
        if($WhatIf){

            Write-Host "Item $itemName would be deleted."
            Add-Content $outFile "Item $itemName would be deleted."
        } else {
            try {
                $ssrs.DeleteItem($item.Path)
                Write-Host "Item $itemName deleted."
                Add-Content $outFile "Deleted item $itemName ."
            } catch [System.Exception] {

        }
    }
}

The following (which was modified from what beargle posted earlier) does what I was looking for. This will list all the data sources by their actual name, and all their dependent items:

SELECT
    C2.Name AS Data_Source_Name,
    C.Name AS Dependent_Item_Name,
    C.Path AS Dependent_Item_Path
FROM
    ReportServer.dbo.DataSource AS DS
        INNER JOIN
    ReportServer.dbo.Catalog AS C
        ON
            DS.ItemID = C.ItemID
                AND
            DS.Link IN (SELECT ItemID FROM ReportServer.dbo.Catalog
                        WHERE Type = 5) --Type 5 identifies data sources
        FULL OUTER JOIN
    ReportServer.dbo.Catalog C2
        ON
            DS.Link = C2.ItemID
WHERE
    C2.Type = 5
ORDER BY
    C2.Name ASC,
    C.Name ASC;
