Question: I wished to import a CSV file representing nulls as empty strings (nothing between the commas). I observed that the .import command by default imports those as empty strings.
A minimalistic example: Let's create a table T with a single column (c) and a file containing only one new line (\n) which I named "onenewline". If you then attempt to import that using the usual import command, the table will receive an empty string: create table T(c); .mode csv .import onenewline T select *,typeof(c) from T; "",text A workaround is to add a view with an instead of trigger and target that with the import instead: create view V as select c from T; create trigger T instead of insert on V begin insert into T select nullif(new.c,''); end; .mode csv .import onenewline V select *,typeof(c) from T; ,null So that works, but I wish there was a more direct method. Am I missing something, or is this the only way? Thanks, Jean
