I am willing to implement a batch update feature by using QueryBuilder to get a result set from database, then change the in the result set and update to database again. However, I get null exception when trying to set value to the result data. Is it not possible to set value in the result set of QueryBuilder?
Exception in thread "main" com.mysql.clusterj.ClusterJDatastoreException: For field data column data valueDelegate object String, error executing objectSetValue. Caused by java.lang.NullPointerException:null
