ON pa.OBJECT_ID = ta.OBJECT_ID
INNER JOIN sys.schemas sc
ON ta.schema_id = sc.schema_id
WHERE ta.is_ms_shipped = 0 AND pa.index_id IN (1,0)
GROUP BY sc.name,ta.name
ORDER BY SUM(pa.rows) DESC

[T-SQL] Transport Level Error

This is the error which i encountered now a days very much:

A transport-level error has occurred when sending the request to the
server.

Here is the reason for it:

You used to have an open connection to a server but you don’t any more. It was closed or killed from the server side. Maybe the server rebooted (or failed-over to another cluster node). You’re talking into one tin can, but nobody’s on the tin can on the other end of the string.

Annoying, but not a problem… open a new connection and try again. If you see this error message from inside SQL Server Management Studio, just hit F5 again (or Alt-X or Ctrl-E depending on preference).
