How to create a macro for creating a symbol in Julia -

-

I am trying to create one in Julia to create a symbol so that S is equal to "x" is : x . It does not work: 

  Julia & gt; Macro S_St (P) Symbol (P) and Julia & gt; S'x 'error: s not defined Julia & gt; S "X" error: x Not defined

The reason is that you

< The pre- macro s_str (p) coat symbol ($ p) can end and

, which is easy to read or more complex, but equivalent. 

  macro s_str (p) esc (: (symbol ($ p)) end

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...
