sql - How to set projection for concatenated result of two columns in Hibernate Criteria -

-

I have trouble bringing the consensual result of two columns to the Hibernate criteria in a single result.

SQL query: 

  choose first name {||] '' || How to set the projection for the inclusion of two columns in the hibernation criteria?  
 
 
   post-text "itemprop =" text "> 
  / benchmarking option (eg expression (coxet ( First name, '', last name), input); // a SQL-like function? Criteria. ("Context (first name, 'last name)", input); / perhaps a database-dependent concatenator? ("First name +" + "last name"); criteria ("first name" 'last name ");

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...
