Hello All,

Finally i got the answer we can use dynamic query using the OR operator as follows.

String[] centerTypesArray = { "Leaderboard", "LearningCentre", "CSRCentre", "SocialCentre", "CommunicationCentre" , "PolicyCentre" , "Idea Centre" , "AppreciationCentre" ,"Public Page"};

DynamicQuery activityQuery=DynamicQueryFactoryUtil.forClass(ActivityData.class,(ClassLoader)PortletBeanLocatorUtil.locate(ClpSerializer.getServletContextName(),"portletClassLoader"))
.add(RestrictionsFactoryUtil.between("publicationliveDate", actdate,curdate))
.add(PropertyFactoryUtil.forName("centretype").in(centerTypesArray))
.addOrder(OrderFactoryUtil.desc("publicationliveDate"));

when we use such kind of query it will search records from the Leaderboard or CSRCentre or others as specified in centerTypesArray .
I am Thankful to all for replying me.

Hi,
you can use use disjunction to put OR conditions as follows.

    DynamicQuery activityQuery=DynamicQueryFactoryUtil.forClass(ActivityData.class,    (ClassLoader)PortletBeanLocatorUtil.locate(ClpSerializer.getServletContextName(),"portletClassLoader"));
		 
		 Disjunction disjunction = RestrictionsFactoryUtil.disjunction();
		 disjunction.add(PropertyFactoryUtil.forName("propertyName1").eq("value1"));
		 disjunction.add(PropertyFactoryUtil.forName("propertyName2").eq("value2"));
		 activityQuery.add(disjunction);

i hope it may help you.

Regards

HI Pradip Gadewar,
As far as i can see your approach towards the dynamic query is wrong . its same as in hibernate .
Here is a sample where you can find your solution

DynamicQuery dynamicQuery = DynamicQueryFactoryUtil.forClass(MyCustomTable.class);
Criterion criterion = null;
criterion = RestrictionsFactoryUtil.like("subject", StringPool.PERCENT + "Test Subject"+ StringPool.PERCENT);
criterion = RestrictionsFactoryUtil.and(criterion, RestrictionsFactoryUtil.between("create_date",10/02/2012,10/03/2012));
criterion = RestrictionsFactoryUtil.or(criterion , RestrictionsFactoryUtil.eq("status", "Pending"));
dynamicQuery.add(criterion);

Hi Ahmad,

Thanks for your Reply, I have checked your link but it will be worked for only 2 names but when i have to compare with 8 to 10 names in or conditions more clearly my DynamicQuery is as follows

DynamicQuery activityQuery=DynamicQueryFactoryUtil.forClass(ActivityData.class,(ClassLoader)PortletBeanLocatorUtil.locate(ClpSerializer.getServletContextName(),"portletClassLoader"))
.add(RestrictionsFactoryUtil.between("publicationliveDate", actdate,curdate))
.add(PropertyFactoryUtil.forName("centretype").eq("LearningCentre"))
.add(PropertyFactoryUtil.forName("centretype").eq("SocialCentre"))
.add(PropertyFactoryUtil.forName("centretype").eq("CSRCentre"))
.add(PropertyFactoryUtil.forName("centretype").eq("CommunicationCentre"))
.add(PropertyFactoryUtil.forName("centretype").eq("PolicyCentre"))
.add(PropertyFactoryUtil.forName("centretype").eq("Leaderboard"))
.add(PropertyFactoryUtil.forName("centretype").eq("Idea Centre"))
.add(PropertyFactoryUtil.forName("centretype").eq("AppreciationCentre"))
.add(PropertyFactoryUtil.forName("centretype").eq("Public Page"))
.addOrder(OrderFactoryUtil.desc("publicationliveDate"));

I have to select a records from the ActivityData Table whose centretypes are LearningCentre or SocialCentre or CSRCentre or CommunicationCentre or PolicyCentre or Leaderboard or AppreciationCentre or Public Page.

In such case I am not able to use Or operator Please Reply me as early as possible....

Hello All,

I am new to liferay, I just build the service layer and now I have to retrieving list of records from table. I just want to write Sql Statement
for following Query.

"Select EmpName from Emp
where EmpName ='Pradip' OR EmpName = 'Ravi' OR EmpName ='Roshan' OR EmpName ='Sushil' ";

I have to write DynamicQuery in Liferay for the above Query.
Consider that i have to give OR condition for 8 to 10 Names.

Can Anybody know how to do this??
