If you see the SSIS 275 error in your SSISDB deployment logs, follow this rigorous troubleshooting checklist.
Note: I assume you mean "SSIS 275" as a course or module code (commonly a university/college course title) about SQL Server Integration Services (SSIS) or a particular SSIS-related topic. If you meant something else (a product model, regulation, or specific component), tell me and I’ll adapt.
Run this T-SQL query on your SQL Server instance to check the SSISDB catalog version: ssis 275
SELECT major_version, minor_version, build_number
FROM catalog.catalog_properties;
On your development machine, check the version of Microsoft.SQLServer.IntegrationServices.dll (usually in C:\Windows\Microsoft.NET\assembly\GAC_MSIL).
| Step | Action |
|------|--------|
| 1 | Read the full error message – note the component name and column. |
| 2 | Enable Event Handlers for OnError to capture the exact row data. |
| 3 | Temporarily set MaximumErrorCount to a high number (e.g., 100) to let the package finish and see all failing rows. |
| 4 | Use a Derived Column to test for problematic values (e.g., ISNULL(MyColumn) ? "NULL" : (DT_WSTR,50)MyColumn). |
| 5 | Run the query directly in SSMS with SET FMTONLY OFF (for OLE DB source). | If you see the SSIS 275 error in
A column in the source contains a value that cannot be converted to the destination column’s data type – e.g., a varchar date '2023-02-30' into a datetime column.
In SSIS, error code 275 is typically associated with: On your development machine, check the version of Microsoft
The key point: The component cannot produce data as expected. This usually happens during the first batch of rows (prime output) due to:
