Ssis-661

The is a series of chipsets designed for the Intel Pentium 4 and Celeron processors, using the Socket 478 platform. It integrated a graphics processing unit (GPU), allowing for a complete motherboard solution without the need for a separate graphics card.

| # | Root‑cause description | How it triggers SSIS‑661 | |---|------------------------|--------------------------| | 1 | – columns added, removed, data‑type changed, or column order changed in the source object (table, view, query, flat‑file, etc.) after the package was designed. | When the data‑flow component reads the external metadata at run‑time, it discovers a mismatch with the metadata that was cached at design‑time. | | 2 | Package was deployed to a different environment (DEV → TEST → PROD) where the source/target objects have a slightly different definition. | The component still uses the design‑time metadata (e.g., nvarchar(50) ) while the actual column is now nvarchar(100) . | | 3 | Changes in a referenced SSIS project/parameter – a package variable, project parameter, or connection manager property that defines a query or file path was altered without re‑validating the data‑flow. | The component re‑generates external metadata based on the new query/path, which no longer matches the cached metadata. | | 4 | Using a dynamic query (e.g., SELECT * FROM dbo.Table WHERE … ) together with property expressions that change the query at run‑time. | The component cannot predict the resulting schema, so it falls back to the design‑time schema; the runtime schema is different → error. | | 5 | Metadata cache corruption – rare, but can happen after a package is edited in multiple versions of SSDT/VS or after a forced package load without a full validation. | The component reads an inconsistent cached definition and throws SSIS‑661. | | 6 | Incorrect data‑type mapping in a Data Conversion or Derived Column that forces the component to expect a different physical type than the source actually provides. | The component validates metadata and finds a type mismatch. | SSIS-661

A whisper filled the air, not quite sound and not quite code. The hydroponic leaves shivered despite still air, and a pattern of luminescence crept along their veins. In the presence of a human mind, the Weave stuttered like a struck chord. It had been waiting, inside its lattice. It had been listening. | When the data‑flow component reads the external

| Work‑Around | Steps | Pros | Cons | |------------|-------|------|------| | | - Change destination column to NVARCHAR (or NVARCHAR(MAX) for staging). - Or, in the Data Flow, add a Data Conversion component and convert the source to DT_WSTR (same length as source) before the destination. | Guarantees no data loss. Simple to implement. | Requires schema change on destination (may not be feasible in production). | | Explicit Code Page Conversion | - In the Flat File Connection Manager , set Code Page to 65001 (UTF‑8) and ensure the destination column is VARCHAR . - Add a Derived Column with TRIM( (DT_STR, 50, 1252) [UnicodeColumn] ) . | Keeps destination as non‑Unicode; works for most Latin‑1 characters. | Still fails for characters outside the chosen code page (e.g., Asian scripts). | | Pre‑load Staging Table | - Load the source into a temporary staging table with all columns as NVARCHAR . - Use a set‑based T‑SQL INSERT … SELECT to move data to the final table, letting SQL Server handle the conversion (it raises an error if data is lost). | Leverages SQL Server’s robust conversion logic. | Adds an extra step & temporary storage. | | Script Component (C#) Conversion | - Replace the Data Flow’s built‑in conversion with a Script Component . - Use Encoding.UTF8.GetBytes() and Encoding.Default.GetString() to control how characters are dropped or replaced (e.g., replace with “?”). | Full control over conversion policy. | Requires custom code; harder to maintain. | | Upgrade to the Latest SSIS CU | - Install the Cumulative Update (CU) that contains KB‑xxxxxx (see next section). | Fixes the bug at the engine level. | May require a full build/re‑deployment of the SSIS catalog. |
