As Cognite provides APIs to access RAW tables from database, is there any way to get the actual datatype (text/bool/timestamp etc.) of the table’s column.

In RAW, all columns are stored as a string.

The documentation says:

The columns object is a key value object, where the key corresponds to the column name while the value is the column value. It supports all the valid types of values in JSON, so number, string, array, and even nested JSON structure (see payload example to the right).

I think the correct answer to the question is that there is no enforced schema, so you can write data with different types to the same column.
