Hi Dmitry,
I would like to iterate through the database (currently SQL Server) to retrieve some tables (the table name comes as a parameter in an Excel file) and save each one into Parquet files. Iteration works perfectly with QVD files, but since I have to manually check each field and set the datatype to export into Parquet, EM raises an error and the process stops.
Additionally, there are issues with datatypes. When exporting, I receive an error: "Error: Column [xxx] contains cells that do not match export type. Source: action 'Export to Apache Parquet', table 'yyy'."
Is there a way to achieve this, and is there a way to force the text datatype on error? I know I can force to text and check the 'Write null option', but doing this removes the error without showing what's wrong, and it requires quite a number of clicks if I have many columns (4 clicks per column).
Or maybe something that could check the datatype errors and filter the involved fields (because right now it's a trial-and-error method field by field).
Cheers and regards,
Chris
