.net - Finding parent records with children in LINQ -

-

I have several foreign key related tables from 1 and I'm wondering how to query a SQL Server in an entity framework What can be the only LINQ query to find the original archived archives? 

  SELECT p.ParentId, p.ParentName FROM Parent p. JOIN Child C. p.ParentId = c.ParentId GROUP BY p.ParentId, P.ParentName Hosting COUNT (c.ParentId) & gt; Internal entries already limit their resultset to those lines where both parents and children are present, then do some work as follows: 
 
 
  Children with different parents = (parent- Parents should join the parents on the parents in the parents. Parents are equal to the child. Parents, new parents (parent) RentId, parent.ParentName}). Specific ();

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...
