I have a syntax error when updating list of items when using room ( (1) near "?": syntax error ) [closed]

Question

my error:

databaseE/SQLiteLog: (1) near "?": syntax error in "update posts_table set list = ?,? where id= ?"

my code:

@Query("update posts_table set list = :list where id= :id")
    Completable updatePost(int id, ArrayList<Integer> list);

Answer 1

write like this

@Query("update posts_table set list = :list where id= :id")

void updatePost(ArrayList list,int id);

I recommend you to convert the arraylist into string and then add the data in db don't add direct the arraylist into it
