how to create criteria query for this native query?
SELECT u FROM Users u WHERE u.userStatus = 0 AND u.firstName LIKE " + "'" + username + "%" + "'"
Am I doing right?
CriteriaBuilder criteriaBuilder = entityManager.getCriteriaBuilder();
CriteriaQuery<Users> criteriaQuery = criteriaBuilder.createQuery(Users.class);
Root<Users> root = criteriaQuery.from(Users.class);
List<String> names = Arrays.asList("Manager", "Sr. Manager");
Predicate predicate1=criteriaBuilder.like((root.get("firstName")), username+"%");
criteriaQuery.select(root).where(predicate1).where(root.get("designation").in(names));
Result:
System considering last where condition.

Here I want to pass a list of Ids and date as a parameter to the database query and I want the query to return data in a Map so the key is the id and List is the data against that id.
Query<Data> query = rdsSession.createNativeQuery(DBQueries.DATA_QUERY,
Data.class).setParameterList("performance_id", listOfIds).setParameter("fromdate", fromDate);
List<Data> listDBRecords = null;
Map<String, List<Data> records=listDBRecords.stream().collect(Collectors.groupingBy(Data::getId));
So how can I achieve this result by passing multiple values(ie. ids) in the query and return that data? This is the query I have written
public static final String SELECT_PORTFOLIO_SECURITY_DATA = "select capl.corporate_action_portfolio_level_id, " +
"capl.performance_id, capl.forwardlooking_sequence_no, " +
"capl.as_of_date, capl.price, casl.currency, capl.exchange_rate, " +
"capl.gross_dividend, capl.net_dividend, capl.sub_portfolio_guid, capl.effective_date, capl.adjustment_weighted_factor, capl.price_adjustment_factor, " +
"casl.share_adjustment_factor, casl.float_adjustment_factor, capl.index_shares, capl.input_tos_live, casl.input_float_live, capl.prediction_type from " +
ConfigurationManager.getProperties().getProperty("rdsConnection.schema") +
".corporate_action_portfolio_level capl inner join " +
ConfigurationManager.getProperties().getProperty("rdsConnection.schema") +
".corporate_action_security_level casl " +
"on capl.performance_id = casl.performance_id and capl.as_of_date = casl.as_of_date and capl.prediction_type = casl.prediction_type and " +
"capl.forwardlooking_sequence_no = casl.forwardlooking_sequence_no " +
"where capl.performance_id = :performance_id and capl.as_of_date = :as_of_date and capl.prediction_type = 'PREDICTED' or capl.prediction_type = 'LIVE'";
Can someone tell what is the right way?
As the title suggests, i'm currently trying to add parts to the JPQL-query using collection-valued named parameters (:queryLst).
Function call:
List<PanelSet> psetLst = setRepository.getMaxZchnrGroupByLeftEight(p.getCustomerNumber(), p.getDrawingNumber(), queryLst);
queryLst:
// Is used to store values from scanned and convert them into parts of a query
ArrayList<String> queryLst = new ArrayList<>();
for (int i = 0; i < size1; i++) {
scanEdvRev = scanned.get(i).toString();
queryLst.set(i, "and left(a.drawingnumber, 8) != left('" + scanEdvRev + "', 8)");
}
SetRepository:
public interface SetRepository extends CrudRepository<PanelSet, Integer> {
#Query("select distinct max(a.drawingNumber) from PanelSet a "
+ "where a.customerNumber = :customerNumber "
+ "and a.drawingNumber != :drawingNumber (:queryLst) "
+ "group by left(a.drawingNumber, 8)")
List<PanelSet> getMaxZchnrGroupByLeftEight(#Param("customerNumber") String customerNumber,
#Param("drawingNumber") String drawingNumber,
#Param("queryLst") ArrayList<String> queryLst);
}
When i run the project i get the following exception:
org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: ( near line 1, column 159 [select distinct max(a.drawingNumber) from com.asetronics.qis2.model.PanelSet a where a.customerNumber = :customerNumber and a.drawingNumber != :drawingNumber (:queryLst) group by left(a.drawingNumber, 8)]
I'm unsure whether my approach to this problem is the correct way of doing this and whether this exception is caused by a simple syntax error or by my usage of collection-valued named parameters.
I've followed this guide trying to solve the problem.
EDIT: I'm basically trying to add each String from ArrayList<String> queryLst to the parametrized query inside setRepository.
#Query("select distinct max(a.drawingNumber) from PanelSet a "
+ "where a.customerNumber = :customerNumber "
+ "and a.drawingNumber != :drawingNumber (:queryLst) "
+ "group by left(a.drawingNumber, 8)")
If successful, the query behind the function
List<PanelSet> getMaxZchnrGroupByLeftEight(#Param("customerNumber") String customerNumber,
#Param("drawingNumber") String drawingNumber,
#Param("queryLst") ArrayList<String> queryLst);
should look like this:
queryStr = "select distinct max(a.drawingNumber) from PanelSet a "
+ "where a.customerNumber = " + customerNumber + ""
+ "and a.drawingNumber != " + drawingNumber + "";
for (String s : queryLst) {
queryStr = queryStr + s;
}
queryStr = queryStr + " group by left(a.drawingNumber, 8)";
I hope this clarifies what i'm trying to do with queryLst.
It can't be done using your approach of passing in a list of query chunks.
The closest you'll get is by adding every possible condition to the query and provide values for all those conditions in a way that allows conditions to be ignored, typically by providing a null.
You code might look like this:
#Query("select distinct max(a.drawingNumber) from PanelSet a "
+ "where a.customerNumber = :customerNumber "
+ "and a.drawingNumber != :drawingNumber "
+ "and a.myTextColumn = coalesce(:myTextColumn, a.myTextColumn) "
+ "and a.myIntegerColumn = coalesce(:myIntegerColumn, a.myIntegerColumn) "
// etc for all possible runtime conditions
+ "group by left(a.drawingNumber, 8)")
List<PanelSet> getMaxZchnrGroupByLeftEight(
#Param("customerNumber") String customerNumber,
#Param("drawingNumber") String drawingNumber,
#Param("myTextColumn") String myTextColumn,
#Param("myIntegerColumn") Integer myIntegerColumn);
Passing null for myTextColumn or myIntegerColumn will allow that column to be any value (except null).
You'll have to find SQL that works for the type of conditions you have and the data type of the columns involved and whether nulls are allowed.
If passing nulls doesn't work, use a special value, perhaps blank for text columns and some "impossible" date like 2999-01-01 fir date columns etc and code the condition like:
and (a.myCol = :myCol or :myCol = '2999-01-01')
Trying to pass column name as parameter but JPA sets it as a value surrounding it with single quotes.
#NamedNativeQueries({
#NamedNativeQuery(
name = "Genre.findAllLocalized",
query = "SELECT "
+ " CASE "
+ " WHEN ? IS NULL THEN genre_default"
+ " ELSE ? "
+ " END localized_genre "
+ "FROM genre ORDER BY localized_genre")
})
Then:
List<String> res = em.createNamedQuery("Genre.findAllLocalized")
.setParameter(1, colName)
.setParameter(2, colName)
.getResultList();
The problem is that the column names being passed are taken as values so the result will return result list with repeated values of "col_name" instead of selecting the value of the column passed as parameter.
Is this achievable?
Basically it makes no sense to create a prepared query like this, how would you name that query anyway: "*"? So the short answer is: no.
But you could create named queries dynamically if this matches your requirement:
String colName = "colName";
String query = "SELECT WHEN " + colName + " IS NULL THEN genre_default";
Query query = entitymanager.createQuery(query);
Probably using a criteria builder is more the way you want to use JPA (code from https://en.wikibooks.org/wiki/Java_Persistence/Criteria):
// Select the employees and the mailing addresses that have the same address.
CriteriaBuilder criteriaBuilder = entityManager.getCriteriaBuilder();
CriteriaQuery criteriaQuery = criteriaBuilder.createQuery();
Root employee = criteriaQuery.from(Employee.class);
Root address = criteriaQuery.from(MailingAddress.class);
criteriaQuery.multiselect(employee, address);
criteriaQuery.where( criteriaBuilder.equal(employee.get("address"), address.get("address"));
Query query = entityManager.createQuery(criteriaQuery);
List<Object[]> result = query.getResultList();
Hi i have the following Query:
String hql = "UPDATE Raumreservierung as rr " +
"set VON = :begin " +
"where VON = :Von " +
"and Raum_ID IN (SELECT r.ID FROM Raum r " +
"inner join r.Panel as pl with pl.ID = " + clientId + "";
IQuery query = CurrentSession.CreateQuery(hql);
query.SetParameter("begin", DateTime.Now);
query.SetParameter("Von", v.Von);
int result = query.ExecuteUpdate();
The Query do an Update on "VON". That works fine, but the rest of the Query is not working. It seems that the rest of the query is not working. But did not get any Error.
With the rest of the Query i mean the following part of the query:
"and Raum_ID IN (SELECT r.ID FROM Raum r " +
"inner join r.Panel as pl with pl.ID = " + clientId + "";
Because it should happen only a Update on the column "VON" for example when "clientId" is "AT2"
But that part is not working. Because the update happens also on other clientId.
You forgot to close your parentheses.
(Also, you should use a parameter for clientId too)
I have a question about Entity Framework. Please answer if you know answer on this. I have such query :
String queryRaw =
"SELECT " +
"p.ProductName AS ProductName " +
"FROM ProductEntities.Products AS p " +
"INNER JOIN CategoryEntities.Categories AS c " +
"ON p.CategoryID = c.CategoryID ";
ObjectQuery<DbDataRecord> query = new ObjectQuery<DbDataRecord>(queryRaw, entityContext);
GridView1.DataSource = query;
GridView1.DataBind();
Particularly I want to join few tables in one query, but I can NOT use LINQ and can NOT use ObjectQuery with objects mapped to DB fields inside my query. Because each entity creates dynamically. So this is what i can NOT use :
msdn.microsoft.com/en-us/library/bb425822.aspx#linqtosql_topic12
msdn.microsoft.com/en-us/library/bb896339%28v=VS.90%29.aspx
The question is can I use something like this instead of using objects?
query.Join ("INNER JOIN CategoryEntities.Category ON p.CategoryID = c.CategoryID ");
The purpose is to use Join method of ObjectQuery with syntax as in Where method :
msdn.microsoft.com/en-us/library/bb338811%28v=VS.90%29.aspx
Thanks, Artem
Any decision i see right now is to temporary convert ObjectQuery to string, add joined table as string and then convert it back to ObjectQuery :
RoutesEntities routesModel = new RoutesEntities(entityConnection);
String queryRaw = "SELECT " +
"rs.RouteID AS RouteID, " +
"rs.LocaleID AS LocaleID, " +
"rs.IsSystem AS IsSystem " +
"FROM RoutesEntities.Routes AS rs ";
_queryData = new ObjectQuery<DbDataRecord>(queryRaw, routesModel);
var queryJoin = _queryData.CommandText + " INNER JOIN LocalesEntities.Locales AS ls ON ls.LocaleID = rs.LocaleID ";
_queryData = new ObjectQuery<DbDataRecord>(queryJoin, routesModel);
Maybe someone has more consistent suggestions?
Finally I Found a better solution for this, we can use Sub Query inside main Query. For example :
var db = CustomEntity();
ObjectQuery<Categories> query1 = db.Categories.Where("it.CategoryName='Demo'").Select ("it.CategoryID");
var categorySQL = query1.ToTraceString().Replace("dbo", "CustomEntity"); // E-SQL need this syntax
ObjectQuery<Products> query2 = db.Categories.Where("it.CategoryID = (" + categorySQL + ")");
Some example is here :

Good luck!
