Insert new data with e.insert.
e.insert(e.Movie, {
title: e.str("Spider-Man: No Way Home"),
release_year: e.int64(2021)
});For convenience, the second argument of e.insert function can also accept
plain JS data or a named tuple.
e.insert(e.Movie, {
title: "Spider-Man: No Way Home",
actors: e.select(e.Person, person => ({
filter: e.op(person.name, "=", "Robert Downey Jr."),
'@character_name': e.str("Iron Man")
}))
});e.params({
movie: e.tuple({
title: e.str,
release_year: e.int64
})
}, $ =>
e.insert(e.Movie, $.movie)
);As in EdgeQL, link properties are inserted inside the shape of a subquery.
const query = e.insert(e.Movie, {
title: "Iron Man",
actors: e.select(e.Person, person => ({
filter_single: {name: "Robert Downey Jr."},
"@character_name": e.str("Tony Stark")
// link props must correspond to expressions
"@character_name": "Tony Stark" // invalid
))
});For technical reasons, link properties must correspond to query builder expressions, not plain JS data.
Similarly you can directly include link properties inside nested e.insert
queries:
const query = e.insert(e.Movie, {
title: "Iron Man",
release_year: 2008,
actors: e.insert(e.Person, {
name: "Robert Downey Jr.",
"@character_name": e.str("Tony Start")
}),
});In EdgeQL, “upsert” functionality is achieved by handling conflicts on
insert statements with the unless conflict clause. In the query
builder, this is possible with the .unlessConflict method (available only
on insert expressions).
In the simplest case, adding .unlessConflict (no arguments) will prevent
EdgeDB from throwing an error if the insertion would violate an exclusivity
contstraint. Instead, the query returns an empty set (null).
e.insert(e.Movie, {
title: "Spider-Man: No Way Home",
release_year: 2021
}).unlessConflict();
// => nullProvide an on clause to “catch” conflicts only on a specific property/link.
e.insert(e.Movie, {
title: "Spider-Man: No Way Home",
release_year: 2021
}).unlessConflict(movie => ({
on: movie.title, // can be any expression
}));You can also provide an else expression which will be executed and returned
in case of a conflict. You must specify an on clause in order to use else.
The following query simply returns the pre-existing (conflicting) object.
e.insert(e.Movie, {
title: "Spider-Man: Homecoming",
release_year: 2021
}).unlessConflict(movie => ({
on: movie.title,
else: movie
}));Or you can perform an upsert operation with an e.update in the else.
e.insert(e.Movie, {
title: "Spider-Man: Homecoming",
release_year: 2021
}).unlessConflict(movie => ({
on: movie.title,
else: e.update(movie, () => ({
set: {
release_year: 2021
}
})),
}));You can use a for loop to perform bulk inserts.
