MySQL subquery to delete rows -

-

To delete some specific rows in my application, I'm having trouble executing a subquery. Here is my wrong SQL: 

  Remove from player_news_items where id in (select player id_imes id, where player_id is not (choose id from player);

What is the correct way to write this query?

In MySQL, you can enter a update or delete join . However, I think you want it: 

  remove player_news_items from pni, where player_id is not (select id from player);

As a note, I recommend it to be written with : 

  player_news_items pni Does not exist (choose from players 1 where p.player_id = pni.player_id);

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
