CSV file format

The first line of the CSV file is the header of the table. You can optionally to add a symbol : and a type name after each field name as a type signature to mark the data type. The available type signature is:

• TextNotNull : The data will be surrounded by ' to represent the string type. The empty item will be replaced by ''.
• Text : Similar with TextNotNull but the empty item will be replaced by NULL.
• Other type signature such as Number, Bool, etc : The data will be directly what it is except emtpy item will be replaced by NULL.

If there's no type signature for one field, it would be TextNotNull. See the format of the file example.csv and the result below.
