java 7 - net.sf.hibernate.PropertyValueException: not-null property references a null or transient value -

-

I am trying to set the 'level' with some values ​​but I get an exception. Below is the version and code.

Hibernate Version: 2.1

Server: Weblogic 11g

Mapping Document: 

  & lt; Property name = "level" type = "java.lang.Integer" & gt; & Lt; Meta attribute = "default-value" & gt; New java.lang.Integer (0) & lt; / Meta & gt; & Lt; Column name = "level" no-null = "true" length = "3" /> & Lt; / Property & gt;

Code: 

  Public poll filled (throws as a result) throws SQLException {POL p = new pol (); P.setLevel (new integer (rs.getInt ("setLevel")); If (rs.IsNull ()) {p.SetLevel (null); } Return p; }

Exception I get 

  by: net.sf.hibernate.PropertyValueException: Not-null property references a blank or transient value

Please help.

That's because you have DB < -> Java DataTip Mismatch

To fix this check:

  • DB column if it is allowed for zero values ​​
  • Java type if it is the initial type or not .

Try the following: 

  Public poll filled (throws as a result) throws SQLException {POL p = new pol (); P.setLevel (new integer (rs.getInt ("setLevel")); If (rs.IsNull ()) {p.setLevel (Integer.valueOf (0)); // According to the mapping you are not emptying it, but return zero; }

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...
