CMS Application - Execute - Fatal Error - Delete Snapshot - Error while executing procedure - More than one row returned by a subquery used as an expression

Mon, 01 Jan 0001 00:00:00 +0000

Purpose (problem description)

The purpose of this page is to troubleshoot the error in snapshot deletion Error while executing procedure - More than one row returned by a subquery used as an expression

See the Cast-MS log file to check the error and sql statement.

 ERROR: more than one row returned by a subquery used as an expression
 Where: SQL statement "Update ADG_DELTA_SNAPSHOTS
 set FIRST_SNAPSHOT_ID = (select s.SNAPSHOT_ID
 from ADG_DELTA_SNAPSHOTS s
 where s.APPLICATION_ID = ADG_DELTA_SNAPSHOTS.APPLICATION_ID
 and s.TEXT_DATE = ADG_DELTA_SNAPSHOTS.FIRST_TEXT_DATE
 )"

 PL/pgSQL function adg_compute_delta_snapshots(integer) line 69 at SQL statement
 SQL statement "select ADG_COMPUTE_DELTA_SNAPSHOTS (13)"
 PL/pgSQL function dss_execute_named_side_process(integer,character varying,integer) line 64 at EXECUTE statement
 SQL statement "select DSS_EXECUTE_NAMED_SIDE_PROCESS(I_SNAPSHOT_ID, 'ALL', I_SIDE)"
 PL/pgSQL function dss_execute_side_process(integer,integer) line 5 at SQL statement
 SQL statement "select DSS_EXECUTE_SIDE_PROCESS(I_SNAPSHOT_ID, -1)"
 PL/pgSQL function dss_purge_snapshot(integer) line 139 at SQL statement

If the CAST-MS log contains the same failing sql statement, then the issue is due to more than one snapshot bearing the same functional date.
After deletion of a snapshot, CAST-MS will re-consolidate the previous and the next snapshots and compute the added/deleted artifacts, then it fails as it finds more than one snapshot with the same date.
It is not possible to generate two snapshots with same functional date from CAST-MS., but the check is not done in CAST-MS-CLI : this is a known issue that will be fixed in 8.2.7

CMS Application - Execute - Fatal Error - Failed to run ADG_COMPUTE_DELTA_SNAPSHOTS

Mon, 01 Jan 0001 00:00:00 +0000

Problem Description

This page describes the solution for the following Error which occurs while uploading results to the measurement base:

Failed to run ADG_COMPUTE_DELTA_SNAPSHOTS (ERROR: more than one row returned by a subquery used as an expression
Where: SQL statement “Update ADG_DELTA_SNAPSHOTS dd set PREV_SNAPSHOT_ID = (……)
PL/pgSQL function adg_compute_delta_snapshots(integer) line 43 at SQL statement)

Applicable in CAST Version

Release	Yes/No
8.3.x	✅

Action Panel

This error often comes when two or more snapshots coming from different centrals have the same functional date.
When the update query is executed the sub-query fetches more the one row with the same functional date of snapshot as a result the upload fails.
To avoid such situation, we need to check for the central bases with the snapshots on the central and update them to have a unique functional date.
