Retrieving data from 3 tables using dynamic query
I have 3 tables user_, userTracker, userTrackerPath
user_ has userId as Pk. which is Fk in userTracker userTracker has UserTrackerId as pk, which is Fk in userTrackerPath and userTrackerPath has userTrackerPathId as Pk.
user_ tables have fields firstName, LastName, loginIp, lastLoginIp userTracker has fields remoteAddr, remoteHost userTrackerPath has fields path_, pathDate
These are all the ones that I need.
I wrote a sql query and it works for me successfully, but I want to get the result using a dynamic query.
Here is my sql query.
select concat(U.firstName," ",U.lastName) as FullName,U.loginIp,U.lastLoginIp,UT.remoteAddr,substring(UT.modifiedDate,1,10) as Date,UTP.path_ from demo.User_ U, demo.UserTracker UT, demo.UserTrackerPath UTP where ((U.userId=UT.userId) and (UT.userTrackerId=UTP.userTrackerId));
I wrote a dynamic query with projections, I'm confused as to how I will attach them.
//Dynamic Query For User Class
DynamicQuery dynamicQuery_user = DynamicQueryFactoryUtil.forClass(User.class,PortalClassLoaderUtil.getClassLoader())
.setProjection(ProjectionFactoryUtil.property("userId"))
.setProjection(ProjectionFactoryUtil.property("firstName"))
.setProjection(ProjectionFactoryUtil.property("lastName"))
.setProjection(ProjectionFactoryUtil.property("loginIp"))
.setProjection(ProjectionFactoryUtil.property("lastLoginIp"));
//Dynamic Query For User and UserTracker Class
DynamicQuery dynamicQuery_userTracker = DynamicQueryFactoryUtil.forClass(UserTracker.class,PortalClassLoaderUtil.getClassLoader())
.setProjection(ProjectionFactoryUtil.property("modifiedDate"))
.setProjection(ProjectionFactoryUtil.property("remoteAddr"));
//Dynamic Query for UserTracker and UserTrackerPath
DynamicQuery dynamicQuery_userTrackerPath = DynamicQueryFactoryUtil.forClass(UserTrackerPath.class,PortalClassLoaderUtil.getClassLoader())
.setProjection(ProjectionFactoryUtil.property("path_"))
.setProjection(ProjectionFactoryUtil.property("pathDate"));
And I tried ..
dynamicQuery_userTracker.add(PropertyFactoryUtil.forName("userId").in(dynamicQuery_user));
dynamicQuery_userTrackerPath.add(PropertyFactoryUtil.forName("userTrackerId").in(dynamicQuery_userTracker));
I know my method is wrong. Any kinds or suggestions.
Thank.

Jay I think you cannot join the DynamicQuery API. You can make subqueries using the in and notin methods.
