"cannot infer the type of the placeholder"
dawkot opened this issue · comments
Basically this code errors at compile-time, and I don't know why:
let categoryName = "Cars"
let s = query:
select product(name, img, price)
join prod_cat(prod, cat) on product.id == prod_cat.prod
join category(name) on category.id == prod_cat.cat
where category.name == ?categoryName # cannot infer the type of the placeholder
This is the sqlite model:
create table product(
id integer primary key,
name varchar not null,
img varchar not null,
price integer not null,
views integer not null default 0,
created timestamp not null default (DATETIME('now')),
modified timestamp not null default (DATETIME('now')));
create table category(
id integer primary key,
name varchar not null,
img varchar not null);
create table prod_cat(
prod integer not null references product(id),
cat integer not null references category(id));
