Where col = null

Hello

Sqlite3 expects the following syntax when when checking for NULL:

SELECT 1 FROM items WHERE col is NULL;

The query where "col = NULL" ( with equal sign ) is used, returns no records.

Hello,

Do we have query like that somewhere, or are you asking about adding code that will replace queries like this with is null?

For example:

sqlite3_lib:read_sql(Tbl, Key, Value) ->
["SELECT * FROM ", to_iolist(Tbl), " WHERE ", to_iolist(Key),
" = ", value_to_sql(Value), ";"].

if Value is null, an equal sign will be used in SQL query, when it seems sqlite3 expects "is" operator.

Ok, i see. Those functions are just for convenience, we expect that for more complex stuff you will need to use sql directly, but i may be able to add handling for this case.
