Anyway, the main point is, the difference between the two syntax variants is lost during the parsing/query-rewriting phase, it does not even reach the query planning and execution phase. So, there’s no question about whether they are equivalent in terms of performance, they become identical long before they reach the execution phase. While the CROSS JOIN is useful in certain scenarios, most of the time, you want to join tables based on a specific condition.
- Using search in Jira Software can help you gain key project insights and answer questions that are relevant to the team.
- Search for issues that are assigned to a particular affects version(s).
- Connect and share knowledge within a single location that is structured and easy to search.
- In addition, we learned how to use these queries and the advantages and disadvantages of each approach.
Use “w”, “d”, “h” and “m” to specify weeks, days, hours, or minutes. Search for issues where the summary contains specific text using Jira text-search syntax. Search for issues that are assigned to a particular sprint. The search is based on either the sprint name or the sprint ID (i.e. the number that Jira automatically allocates to a sprint). Search and sort through your requests to ensure that you’re hitting your SLA goals. You can search for requests whose SLAs are in a certain state of completion, or that have a certain amount of time on their SLA clock.

The three flavors of search in Jira software — quick, basic, and advanced — can help you find important information about your projects. The engine takes the JQL.QUERY string (VARCHAR) from the WHERE condition and passes it to the JQL table which resolves it against the Atlassian’s public Java API for Jira. Then the JQL is populated with the records, one per returned issue id along with the Issue Lucene document in the JQ.ISSUE column. This is extremely helpful for organizations that have service level agreements (SLA) with their customer base. A JQL query can easily find the issues that are not meeting that SLA.
SQL is a declarative language that focuses on specifying what needs to be done without specifying how. Users write SQL queries that specify the desired result set, while the database management system handles any necessary underlying processes or optimizations. A simple query in JQL (also known as a “clause”) consists of a field, followed by an operator, followed by one or more values or functions.
Criteria Queries
It’s safer to search by status ID than status name since it’s possible for your Jira administrator to change the name of a status, which would break any saved filter that relies on that name. Search for requests that were created on, before, or after a particular date (or date range). Search results are relative to your configured time zone (which is by default the Jira server’s time zone). You can search by project name, by project key or by project ID (i.e. the number that Jira automatically allocates to a project). In the rare case where there is a project whose project key is the same as another project’s name, then the project key takes preference and hides results from the second project.
It is also possible for your Jira administrator to change the name of a version, which could break any saved filters that rely on that name. Note that you don’t invoke the persist method for the retrieved PurchaseOrder instance, nor for its related OrderLineItem instance being modified here. In spite of this fact, the changes made to the first line item in the order will be persisted to the database upon committing the what are JQL queries and how to use them transaction. This happens because both the retrieved entity instances and their associations are automatically attached to the current persistence context. As mentioned earlier, the former become managed when they are retrieved, and the latter are attached to the context as you access them. Conversely, JavaScript is a general-purpose programming language that can be employed for numerous tasks beyond data management.
The “CHANGED” operator is used to find issues that have a value that had changed for the specified field. This page describes information about operators that are used for advanced searching. I wanted to create a advanced search but at the end I fail everytime at the JQL. The “in” keyword will include any item that matches any item in the list. In the above example it will return all of the blocker and critical bugs in projects A, B, and C. If I read that correctly the grammar defines three predicates solely for use with the boolean datatype IS TRUE, IS FALSE, IS UNKNOWN.
Search for issues that belong to a particular epic in company-managed projects. The search is based on either the epic’s name, issue key, or issue ID (i.e. the number that Jira automatically allocates to an issue). In contrast, JavaScript is a procedural and object-oriented programming language. Developers write code in an organized fashion, specifying how tasks should be carried out.
