更改SQL列的数据类型时更新SSIS包

Question

We have to update the datatype for a column in SQL table which is used a source in a SSIS package. But when I run the SSIS package after updating the data type it fails due to datatype mismatch.

How can I have SSIS package recompile/revalidate the sourcecode so it doesn't fail?

Answer 1

You will need to open the SSIS package itself. From this point, go to any component that uses this object, right-click this and select Show Advanced Editor... then press the Refresh button on the Connection Manager pane to update the metadata. I'd also recommend double-checking any column mappings to verify that the data types and lengths are compatible.

Answer 2

You can open the existing package and run a data conversion or simply create a new one and overwrite the existing one with the conversion.
