I have the following Query:
query {
table1(where: {table2: {id: {}}}) {
id
}
}
There is a relationship between table1 and table2 via a foreign key. That is, in table2 I have a column named table1_id and so I can access table2 from table1. I want to query all rows from table1 that have no related rows in table2. That is, if I do the following query:
query {
table1 {
table2 {
id
}
}
}
I want the rows in table1 where this query returns an empty array. I have tried the following:
query {
table1(where: {table2: {id: {_in: []}}}) {
id
}
}
And
query {
table1(where: {table2: {id: {_is_null: true}}}) {
id
}
}
But nothing seems to work (I get back an empty array). What am I doing wrong?
query {
table1(where: {_not: { table2: {} } }) {
id
}
}
Should work to return the records from table1 that don't have a relationship with table2
The selected answer is actually incorrect. It should be the following:
query {
table1(where: {_not: { table2: {} } }) {
id
}
}
Edit: The selected answer is good now :)
