Hello, I am creating a pipeline with a Copy activity to get a table from SQL databse to Synapse and I am getting this error : Column '' has a data type that cannot participate in a columnstore index. How can I fix this in ADF ? Thank you

    Hi Wajih Arfaoui,

    Thanks for reaching out to Microsoft Q&A.

    Disable Columnstore Index:

    • Try disabling the columnstore index on the target table before running the copy activity. To do this, drop the columnstore index using the following command. Once done try to rerun and check if you face the same issue.
      DROP INDEX [index_name] ON [table_name]
    • If the above is not possible, try Merge method instead of upsert(if you use them).

    • Did you try using the clustered index?
