Sinus tachycardia is recognized on an ECG with a normal upright P wave in lead II preceding every QRS complex. This indicates that the pacemaker is coming from the sinus node and not elsewhere in the atria, with an atrial rate of greater than 100 beats per minute.

The index is.

JPA allows the use of SQL by taking advantage of the entity model and the management of server transactions. The JPQL language and the CriteriaAPI are independent of the underlying database and can be used to query.

The first is based on text strings and the second on objects and methods.

It is a note.

The chapters of JPQL assume that the reader knows how to use a database. I am not going to give a lot of detail about how a query works.

The Jakarta Persistence Query Language is also known as JPQL. It is based on the ideal language for these tasks and that all programmers know how to use it. The novelty of JPQL is that it does not use tables and columns.

The data model of the application is completely abstract from the table structure. We can define JPQL as an entity query language. The JPA implementation will translate the JPQL statements into a database language so that they can be executed in the database.

HQL is a standard of query language. The JPA entity manager and its associated classes are used to execute the queries. HQL has features that are not covered by the standard, so the opposite is not always correct. Some of them will make our lives simpler.

The test entity model was taken from examples in the previous chapters.

Below is a query that will show all expenses sorted by the amount of currency they are in.

This is the same as the JPQL.

The structure is the same, but we already appreciate differences. The FROM clause does not apply to the table.

The name of an entity is the same as the name of the class, unless otherwise specified in the @Entity annotations. If we want the whole entity, we indicate its alias in the projection. You have to respect the name of the entity and attribute in JPQL. I will follow the usual practice of using reserved words and functions.

In IntelliJ, the JPA Buddy helps us build queries.

In the next two chapters, the execution of JPQLHQL queries will be covered. I think the ones we are going to see can be done like this.

The query execution consoles are created from a persistence.xml file and a database connection, and we will have to set them up. We have it in the persistence view in IntelliJ.

The basic features of SQL are provided by JPQL. Let's see what we can and can't do.

It is possible to return complete entities, or a combination of both. The result of certain functions, including aggregation functions, can be called scallers.

When the projection consists of the FROM variable, the SELECT clause is optional.

I will use it in all of the examples to make sure they are compatible with the standard.

The operator will not result in duplicate results.

Combining the name attribute with the "dot" operator can help navigate relationships.

In the next part of the course, we will see this "magic" in more detail because it involves the meeting or joining of entities.

The case selection structure is also supported. It behaves like a switch statement or if-else structure

The conditions are evaluated in order. The rest are not checked as soon as a scalar is returned. The result of the else clause is returned if neither is true.

The case-when clause does not support subqueries.

This query gets a list of expenses and a text with the amount in it's value.

The condition has been indicated. It can be used to perform an "is equal to" check on a value.

Return a calculated logical value is a typical use.

We can find out the existence of an expense without actually paying it.

When we need to evaluate for null values, CoaleSCE is a simplified way to write a case when block. Receives a list of arguments and returns the first one that is not null. The concept is returned if the expense comment is null.

This one is equivalent to it.

There is a particular case of evaluation called NULLIF.

If the two values it gets are equal, then returns zero. The first one is returned if it isn't already returned.

If it doesn't match its description, this example will get its concept for each expense. When both are equal, return a null number.

The following is the same as it is.

We don't need to retrieve entities if they are incomplete, or if they have all their attributes. Sometimes we need a class tailored to our query.

Projected values can be encapsulated in an object using a constructor. Data transfer objects, classes that are limited to containing data and that must ensure that they are immutable, are some of the topics we are discussing.

They don't have any functions apart from providing getters. Since Java 14, they can be replaced with records.

The ExpenseDTO class is very simple.

The only annotations that could be applied are the ones in the DataAnnotation.

We should only return entities if we need to work with them in a persistence context. It is more efficient to collect the information that is necessary at all times in DTOs or records using the constructor technique in other cases. We incur a cost if we recover entities.

DTOs are general-purpose data stores, so they can be sent to any layer or module of the application, for example to classes with the services of a REST API. If we do the same with entities, we will be spreading code from the persistence classes throughout the system because they have JPA Hibernate annotations. If we want to build flexible and maintainable systems, we need to avoid this.

The usual solution to avoid exposing entities outside their natural environment is to dump their data with mapper methods in DTOs.

If we make the queries return the DTOs when the entities are not essential, it will be a tedious task.

In this clause, we assign the entities with which we are going to work a variable or aliases to be able to reference them in the projections, theWHERE or even from itself.

We can find individual declarations or meetings of entities with JOIN. I will dedicate a chapter of these meetings.

The JPQL WHERE clause is similar to the SQL one. It is used to define selection conditions based on the results produced by the collections of entities defined in the FROM.

We always select expenses of at least one hundred currency units in this query.

If we want to apply any other amount? We need a variable to which we will give a value each time the query is executed.

The only way to distinguish the values from the code is to use the order of declaration.

The code is hard to read because it is prone to errors. JPQL allows for the identification of each distinct parameter with an index, which makes it more convenient.

Better still, with a descriptive name.

The assignment of the values to the parameters in code is done by the same person, so we don't have to worry about following any particular order.

We will see in the next chapter

The attributes of the entities and some operators from the database do not need to be introduced to the selection expressions.

UNION will probably be available in HQL in Hibernate 6.

We can navigate relationships as well.

Four unique operators are added by JPQL.

Whether a collection has elements or not is the subject of a report. The categories with a budget list are not empty.

The EXISTS operator is used to translate these operators into the database to check for results for a sub query. If the list is not empty, it is because at least one budget exists.

The possible membership of an entity in a collection is checked by the member of and not member of operators. The categories that are not part of the list of categories of the budget are indicated with a parameter.

The non-collection membership condition has been implemented.

budget is an entity that we must provide, but it is not enough that its object contains the identifier.

Subqueries support the WHERE selection in the above two SQLs. A sub query is a normal query enclosed in parentheses and placed inside another parent or main call. The sub query can access the parent query's data if it is necessary.

The result of the sub query is used in a variety of ways. The possibilities will be dependent on the database.

Subqueries can be found in JPQL, but they can only be seen inside where, hogging, and the SET that accompanies the update.

The two JPQL queries that were in the previous section should be rewritten.
