在 ArangoDB 中的 collections 之间移动文档

Question

Is there a simple way to move documents between collections in ArangoDB? I tried the cheap approach to just alter the _id , but as feared that's not supposed to be done or possible:

FOR i IN collection_A
UPDATE { _key: i._key, _id: CONCAT('collection_B/',i._key) } IN collection_A

Are there useful ways how I can move my document from collection_A to collection_B with AQL?

Answer 1

You could try something like

FOR i IN collection_A
    LET i_b = UNSET(i, "_id") // Remove the id that is not valid before insert
    INSERT i_b INTO collection_B
    REMOVE i IN collection_A

Answer 2

Just do an insert instead of an update For I in collection_A Insert into collection_B

FOR u IN collection_A
   INSERT u IN collection_B
