To elaborate, Jira is a popular issue & project tracking software built by Atlassian, which is similar to a database with contains details about issues. In this database, looking for specific information will be quite hard as looking for your beloved’s ring in the ocean. Then you probably will have stumbled upon the search function in Jira.
Here are some practical tips to help you enhance your Jira advanced search abilities. Simple, check the entire query below & notice how we have added the OR keyword, used brackets to combine two seemingly different criteria together. The list of JQL keywords is actually small & pretty much self-explanatory. Following keywords are available to use in Jira – AND, OR, NOT, EMPTY, NULL, ORDER BY. Since the purpose of JQL queries is to retrieve information from Jira based on advanced user needs, it needs to follow a certain pattern or structure. This detailed guide about JQL or Jira Query Language will set you on the path to success with sufficient breadth & depth of knowledge.
Use advanced search with Jira Query Language (JQL)
Constructor references are a good projection for read-only use cases. They’re more comfortable to use than scalar value projections and avoid the overhead of managed entities. As you can see, I use the ‘.’ operator to navigate via the publisher attribute of the Book entity b to the related Publisher entities. That creates an implicit join between the Book and Publisher entity which will be translated into an additional join statement in the SQL query. Path expressions create implicit joins and are one of the benefits provided by the entity model.
It is, therefore, a good practice to activate the logging of the SQL statements during development to check the generated SQL statements. 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. Mastering JQL is the key that unlocks the hidden vaults of productivity and efficiency within Jira, propelling your project management endeavors to unprecedented heights.
Make Jira do as much work as possible
JIRA gives suggestions at each step of the way for each of the three components of our query. When you see the value you’d like to select, you can use the arrow keys or mouse to select it. That’s why we have developed an app for Jira cloud that lets you search any such entities on your Jira instance. And the good thing is that it takes all its structure from the Jira JQL. Advanced JQL queries section led the discussion with the nuances & then dived deeper into practical examples. These examples illustrated how you can tackle real-world scenarios.
- The initial part of this guide was focused on the basic concepts.
- It includes the most commonly used functions, operators, and syntax examples, making it easier for you to construct queries without having to memorize everything.
- For example, as you search with an assignee, issues allocated to that particular assignee appear on the board.
- This will do two things – it will be easier for you to build the query in small pieces & it will also control the order of operations.
- But there is an important difference that I want to point out before I walk you through the different parts of a JPQL query.

null when it looks for the value for
“ID”. JPQL supports a set of basic operators to define comparison expressions. Most of them are identical to the comparison operators supported by SQL, and you can combine them with the logical operators AND, OR and NOT into more complex expressions. The next important part of a JPQL query is the WHERE clause which you can use to restrict the selected entities to the ones you need for your use case. The syntax is very similar to SQL, but JPQL supports only a small subset of the SQL features. If you need more sophisticated features for your query, you can use a native SQL query.
Any known limitations of JQL?
In this example the person filing the bug is stored in the reporter field. Again, we can set up multiple conditions joined by the AND keyword. Effective project management requires specific metrics from the issue tracker relevant to your project. Continuous learning and hands-on practice are key to mastering this SQL like query language and becoming more proficient in searching Jira issues.
Development managers often have to find areas of risk in their programs. Good queries often take a bit of refinement as they get developed. In this query the “is empty” statement tells JIRA to return only issues where the value of the assignee field is blank. The value -1d evaluates to 1 day behind the current date when the query is run. As a result, the above query will return all issues that do not have an assignee and haven’t been updated in the past day. By implementing these tips and tricks, you can make the most of Jira advanced search and significantly improve your ability to manage and track issues in Jira.
JPQL – How to Define Queries in JPA and Hibernate
Using similar code and a native query casting to a Customer won’t work, a ClassCastException will be raised.
For example, if you wanted to see all the critical bugs created in the last 30 days from project AR that are not fixed – this is what the basic search would look like. JPQL is a powerful query language that allows you to define database queries based on your entity model. But there is an important difference that I want to point out before I walk you through the different parts of a JPQL query. In all the queries we’ve discussed so far, the data is reflective of the current time the query was run. But values for fields like assignee, priority, fix version, and status often change over the course of an issue’s lifecycle. JIRA stores each update an issue goes through, known as an issue’s change history.
JQL: the most flexible way to search Jira
Having a JQL cheat sheet can be incredibly helpful for quick references. Download our comprehensive PDF cheat sheet below and keep it handy. It includes the most commonly used functions, operators, and syntax examples, making it easier for you to construct queries without having to memorize everything. Hibernate uses the mapping information of the selected entities to determine the database columns it has to retrieve from the database.
They have made this SQL like query language as popular as it is today. That’s the primary role of keywords in the context of Jira query language. For example, the default priority field has possible values of Blocker, Critical, Major, Minor, Trivial. Similarly, assignee field will have the users as possible values. When you have hundreds of columns and tens of thousands of rows, it’s much easier to use a database to store information and use Structured Query Language (SQL) to access the data.
The identification variable is often called alias and is similar to a variable in your Java code. It is used in all other parts of the query to reference this entity. 5) Keyword – Words/phrases that add specific conditions jira query examples to your queries. And, or, not, empty, null, order by, is and more can be counted as keywords. JQL is widely adopted by project managers, software development teams, support teams, and other Jira users.
