Jenna needed to understand why ShipDate was NULL for a handful of rows. She queried the operational system that fed the staging table:
SELECT *
FROM dbo.OrderEvents
WHERE OrderID = 457812;
The result set revealed that the order was in “Pending” status and the shipping process had not yet been triggered. The ETL pipeline had been pulling every row with LoadDate = today, regardless of completion status.
In other words, the source system was exposing incomplete transactions that the data warehouse was not prepared to handle.
Jenna opened the SSIS catalog in SQL Server Management Studio and inspected the execution logs for the last three days. The pattern was clear:
| Date | Rows Processed | Rows Failed (SSIS‑948) | |------------|----------------|------------------------| | 2026‑04‑13 | 1,245,678 | 12 | | 2026‑04‑12 | 1,247,011 | 0 | | 2026‑04‑11 | 1,246,532 | 7 |
Only a handful of rows were being rejected, but each failure stopped the entire package because the FailPackageOnFailure flag was set on the OLE DB Destination. ssis-948
She pulled the source query from the Data Flow:
SELECT
OrderID,
CustomerID,
OrderDate,
ShipDate,
TotalAmount
FROM dbo.StagingOrders
WHERE LoadDate = CAST(GETDATE() AS DATE);
The destination table dbo.FactSales defined OrderDate as NOT NULL and had a CHECK constraint that the date must be on or after 1900‑01‑01. Nothing seemed wrong at first glance.
Jenna then ran a quick ad‑hoc query to see if any rows actually had a NULL OrderDate:
SELECT TOP 10 *
FROM dbo.StagingOrders
WHERE LoadDate = CAST(GETDATE() AS DATE)
AND OrderDate IS NULL;
The result set was empty. Yet the error insisted a NULL was trying to sneak through.
If you want, I can draft the DB schema for the watermark store and a sample SSIS control-flow using the new tasks. Jenna needed to understand why ShipDate was NULL
Jenna remembered that the package contained a Derived Column transformation that calculated a “CorrectedOrderDate”:
CorrectedOrderDate = ISNULL(OrderDate, DATEADD(DAY, -1, ShipDate))
The logic was meant to back‑fill missing dates with the previous day’s ship date. The derived column was then mapped to the destination column OrderDate.
She opened the data viewer on the Data Flow, set a breakpoint after the Derived Column, and ran the package in debug mode. As rows streamed by, everything looked perfect—CorrectedOrderDate always held a value.
But then, a breakpoint hit on row # 5,932. The viewer showed:
| OrderID | CustomerID | OrderDate | ShipDate | TotalAmount | CorrectedOrderDate | |---------|------------|-----------|------------|-------------|--------------------| | 457812 | 1023 | NULL | 2026‑04‑15 | 1250.00 | NULL | The result set revealed that the order was
The derived column had failed to compute a value! The ShipDate for that row was also NULL (a rare but possible scenario when an order was still being processed). The expression ISNULL(OrderDate, DATEADD(DAY, -1, ShipDate)) returned NULL because both arguments were NULL.
That was the culprit. The package’s defensive logic was incomplete.
Upon its initial release, SSIS-948 topped several sales charts within its distribution networks. More impressively, it maintained a high position in "repeat rental" and digital download metrics for over six months—indicating a title viewers return to, rather than one consumed and forgotten.
On review aggregator sites dedicated to Asian cinema, SSIS-948 holds a rating of 4.7/5 across more than 1,200 user-submitted reviews (as of early 2025). Praise centers on:
However, not all feedback is glowing. Some detractors argue that the slow pacing betrays genre expectations, and that the philosophical ambitions outstrip the script's reach. Nevertheless, even negative reviews tend to acknowledge the film's craftsmanship.
A nightly package loads CSV files from a shared folder into a SQL Server table. The package fails with:
Error: 0xC020901C at Data Flow Task, OLE DB Destination [1]: SSIS Error Code 0xC020901C.
The component "OLE DB Destination" (1) failed because the connection manager "AdventureWorksDW2019" failed to acquire a connection.
