| Pitfall | Why It Happens | Fix | |---------|----------------|-----| | in connection strings | Deploying to another environment (Dev → Prod) where the login does not exist. | Use SSIS Package Configurations or Project Parameters + SSIS Catalog environments to inject credentials at runtime. | | Running the package as a 32‑bit process when the provider is 64‑bit only | Provider fails to load, sometimes surfaces as 927. | Set Run64BitRuntime = False only when you truly need the 32‑bit provider (e.g., Access, Excel). | | Database in RECOVERY or SUSPECT | SQL Server cannot open the DB, so any login is denied. | Bring the DB online before running the package. | | Missing EXECUTE AS clause in stored procedures that the package calls | The stored procedure runs under the caller’s context, which may lack rights. | Add WITH EXECUTE AS OWNER (or a specific user) to the procedure, or grant the caller rights directly. |

| Transformation | When to Use | Tips | |----------------|------------|------| | | Small reference tables (≤ 2 M rows). | Set Cache mode = Full for fastest performance. | | Lookup (Partial/No Cache) | Large tables, memory‑constrained. | Use Partial and set CacheSize appropriately. | | Merge Join | Joining two sorted streams. | Sort upstream to avoid spool; use Inner Join for performance. | | Script Component (Transformation) | Complex row‑level logic (e.g., regex, custom hashing). | Write in C#; expose ReadOnly and ReadWrite columns via Inputs and Outputs . | | Conditional Split | Route rows based on expression. | Combine multiple predicates in one split to reduce downstream components. | | Data Conversion | Convert data types before loading to destination. | Prefer native source conversions where possible (e.g., set DataType on OLE DB Source). | | Multicast | Duplicate a data stream to several branches. | Use sparingly; each branch adds a buffer copy. | | Recordset Destination | Store rows in an ADO.NET Recordset for later use in a Script Task. | Not recommended for large rowsets (use staging tables instead). | | Pitfall | Why It Happens | Fix
