    <p>I have a file(this file actually has tab separated values) which has to be written into one of the database tables. This file can contain duplicate entries as well. I am processing the records in the file in set of 5000, so I first parse these first 5000 records in the file if they contain any duplicate entries I simply ignore the duplicates and write the unique records among them to the database and again process next 5000 records in the similar fashion till EOF is reached. Now while writing these 5000 records it is possible that there are duplicates between the sets of 5000 records and if so happens(then database throws the DomainObjectExistsException) then I catch the exception and simply update the record. I am performing the update operation like this:</p> <pre><code>getHibernateTemplate().saveOrUpdate(femtoFactoryData); </code></pre> <p>Where femtoFactoryData is a java Object(POJO) which has to be written into the database table constructed from the tab-separated values in the file. The Primary Key of the table is nothing but the ID of the Femto and the state(Temporary/Permanent).</p> <p>But while performing this update operation I am getting:</p> <pre><code>org.hibernate.exception.ConstraintViolationException </code></pre> <p>Here is the stacktrace from my program:</p> <pre><code>org.hibernate.exception.ConstraintViolationException: could not insert: [com.airvana.anp.model.db.domainobjects.FemtoFactoryData] at com.airvana.anp.model.db.impl.DbManagerGlobalUtils.convertException(DbManagerGlobalUtils.java:68) at com.airvana.anp.model.db.impl.FemtoFactoryDataDAOImplHelper.updateFemtoFactoryData(FemtoFactoryDataDAOImplHelper.java:302) at com.airvana.anp.model.db.impl.FemtoFactoryDataDAOImpl.updateFemtoFactoryData(FemtoFactoryDataDAOImpl.java:149) at com.airvana.anp.model.oss.imports.common.DataRecordDAOHelperImpl.updateRecord(DataRecordDAOHelperImpl.java:725) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:310) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:198) at $Proxy89.updateRecord(Unknown Source) at com.airvana.anp.model.oss.imports.parser.ParseControllerImpl.saveDupFactoryRecordsInDb(ParseControllerImpl.java:477) at com.airvana.anp.model.oss.imports.parser.ParseControllerImpl.parseFile(ParseControllerImpl.java:111) at com.airvana.anp.model.oss.imports.FactoryOperationsManagerImpl.onAllocation(FactoryOperationsManagerImpl.java:192) at com.airvana.anp.model.resource.impl.CallbackWorkerJob.run(CallbackWorkerJob.java:43) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:650) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:675) at java.lang.Thread.run(Thread.java:595) Caused by: org.springframework.dao.DataIntegrityViolationException: could not insert: [com.airvana.anp.model.db.domainobjects.FemtoFactoryData];

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
