Data Type Conversion in Delimited File Data Source

Hi, I am trying to create a Selection View in order to convert text value columns in a delimited file based data source to other data types, based on : https://community.denodo.com/docs/html/browse/7.0/vdp/administration/creating_data_sources_and_base_views/excel_sources/excel_sources Initially, I was attempting to convert data strings, using to_timestampz() function, but this always results in a <null> value. I then tried to convert simple numeric strings to decimal/int/float types, but again, this always results in <null> Now, I appreciated that this is specifically for Excel files – but was assuming this would also work for delimited file sources. However, having revisited the documentation for Delimited File Sources, I do not see any such information on conversion. Does this mean, it is simply not possible to convert text values in a delimited file source?

Hi, When you create a base view over a text file (or any other source) you have the opportunity to change the data type There is a drop down against the field type and you can change text to a numeric data type, as long as the data itself supports the new data type. You can edit your base views and make any changes you need. Regards...
