i was querying the ssis catlog to find out the name of all the packages in the catalog.
There are only 6 packages in the Folder1 project,but the query gives 9 records
1. SELECT P.NAME FROM SSISDB.internal.projects PRJ INNER JOIN
SSISDB.internal.packages P ON
P.project_version_lsn=PRJ.object_version_lsn WHERE
PRJ.NAME='Folder1'
Does it show the deleted packages from the project as well.
They aren't deleted, that's part of the historical tracking. You likely wanted a query more similar to
SELECT
F.name AS FolderName
, P.name AS ProjectName
, PKG.name AS PackageName
FROM
ssisdb.catalog.folders AS F
INNER JOIN
SSISDB.catalog.projects AS P
ON P.folder_id = F.folder_id
INNER JOIN
SSISDB.catalog.packages AS PKG
ON PKG.project_id = P.project_id
ORDER BY
F.name
, P.name
, PKG.name;
This reflects that Folders contain Projects and Projects contain Packages so that will provide the exact "address" for a given package.
