That is, it is used to search for issues where the specified field has a value. That is, it is used to search for issues where the specified field has no value. The result of the above sentence is a text string that will be executed and resolved by the JQL what are JQL queries and how to use them table returning all the issues in that project version. Then, the engine will check whether the assignee is John Smith for all the fetched issues. If the currentUser() reported N issues, checking the assignee by the SQL+JQL engine will occur N times.

Note when i used the following named query (mentioning the fields/column) the performance have not increased. It is interesting to note that using a SELECT JPQL statement is not the only way to go when it comes to retrieving a single entity instance. Alternatively, you might utilize the EntityManager’s find method, which lets you retrieve a single entity instance based on the entity’s id passed in as the parameter. Of special interest here are the createQuery method of the EntityManager instance and the getResultList method of the Query instance.

Common Applications for JavaScript include:

The “WAS” operator is used to find issues that currently have or previously had the specified value for the specified field. Note that not all fields are compatible with this operator; see the individual field reference for details. The JQL table is the most convenient way to perform JQL queries and transforms JQL results into SQL records.

The createCriteria() method from the Hibernate Session returns the persistence object instance for running a criteria query in the application. Simply put, the Criteria API builds up a criteria query that applies different filters and logical conditions. Donald D. Chamberlin and Raymond F. Boyce explicitly created SQL for working with relational databases, where data is organized in tables with predefined relationships between them. However, its primary function is managing, querying, and manipulating this structured information – making it highly specialized in database-related tasks. Advanced search allows you to build structured queries using Jira Query Language (JQL) to search for issues within and across projects. Query results can be saved and used as filters and views across Jira (including boards).

Basic and Advanced Searches

The code snippets discussed in the article are taken from the Java source files used in the sample application accompanying the article. Looking through the sample archive, you may notice that this is a simple Web application based on the Java Servlet and Java Persistence API technologies. For simplicity, it doesn’t use enterprise beans, issuing JPQL queries directly from within servlets. It doesn’t mean, however, that you won’t be able to utilize the JPQL queries discussed here in enterprise beans—you can define JPQL queries in any Java EE components. You can search by issue type name or issue type ID (i.e. the number that Jira automatically allocates to an issue type).

This is (IMHO) utterly confusing to a human, and it’s very easy to forget to link table1 to anything (because the “driver” table doesn’t have an “on” clause), but it’s legal. However, IMHO, I think it’s much clearer to use the ON clause when performing joins. That way you have a specific section of you query that dictates how the join is handled versus intermixed with the rest of the WHERE clauses. An INNER JOIN statement can be rewritten as a CROSS JOIN with a WHERE clause matching the same condition you used in the ON clause of the INNER JOIN query.

Joining SQL tables via dynamic JQL

While it can interact with databases (through APIs), its primary use is creating and controlling web application logic, user interfaces, and server-side applications. As such, JavaScript offers greater versatility and is suitable for an array of projects. Note, it is safer to search by component ID than by component name. Different projects may have components with the same name, so searching by component name may return issues from multiple projects. It is also possible for your Jira administrator to change the name of a component, which could break any saved filters that rely on that name. Search for issues that are assigned to a particular affects version(s).

Note, it is safer to search by resolution ID than by resolution name. It is possible for your Jira administrator to change the name of a resolution, which could break any saved filter that rely on that name. Note, it is safer to search by priority ID than by priority name. It is possible for your Jira administrator to change the name of a priority, which could break any saved filter that rely on that name.

You can search by issue level security name or issue level security ID (i.e. the number that Jira automatically allocates to an issue level security). If you need to be able to search specifically for issues with an outward description of “blocks”, for example, a Jira administrator must change the name of the link type to something else. If you’re a Jira admin, take a look at Configuring issue linking for more info. Note that the Lucene value for Customer Request Type, is portal-key/request-type-key. While the portal key cannot be changed after a service project portal is created, the project key can be changed.
