null Standard SQL boolean operator IS vs equals = operator

In most cases, however, you will have to deal with queries that receive an instance or a list of instances of a certain entity. Note, it is safer to search by custom field ID than by custom field name. It is possible for a custom field to have the same name as what are JQL queries and how to use them a built-in Jira system field; in which case, Jira will search for the system field (not your custom field). It is also possible for your Jira administrator to change the name of a custom field, which could break any saved filters that rely on that name.

  • Search for issues that were last updated on, before, or after a particular date (or date range).
  • Spring Data provides multiple ways to create and execute a query, and JPQL is one of these.
  • The “WAS” operator is used to find issues that currently have or previously had the specified value for the specified field.
  • Using similar code and a native query casting to a Customer won’t work, a ClassCastException will be raised.
  • In many cases, using SQL and JavaScript is the optimal solution, particularly in web development.

In addition, we learned how to use these queries and the advantages and disadvantages of each approach. The main advantage of Criteria Queries over HQL is the nice, clean, object-oriented API. As a result, we can detect errors in Criteria API during the compile time. For the latter query above, the name method argument is passed as the query parameter with respect to index 1, and the salary argument is passed as the index 2 query parameter. Before we dive in, we should note that the Hibernate Criteria API has been deprecated since Hibernate 5.2. Therefore, we’ll be using the JPA Criteria API in our examples, as it’s the new and preferred tool for writing Criteria queries.

This field is only available if time tracking has been enabled by your Jira administrator, and can only support the CONTAINS operator (“~”). Search for issues where the remaining estimate is set to a particular value (i.e. a number, not a date or date range). Search for issues where the original estimate is set to a particular value (i.e. a number, not a date or date range). Only available if issue level security has been enabled by your Jira administrator. For example, add a red stripe to issues that have some blockers, and keep all other issues green.

jql vs sql

JavaScript, however, is an incredibly versatile and powerful programming language commonly used in web development. Front-end developers, full-stack developers, and web application engineers will find JavaScript invaluable when creating responsive and user-friendly applications. JavaScript is your best bet if your project involves creating dynamic interactive web applications or server-side programming.

In this article, you will learn some interesting ways of using JPQL, as well as native SQL to query over entities utilized within a Java application. Learn how to take advantage of the Java Persistence query language and native SQL when querying over JPA entities. You can search by status name or status ID (i.e. the number that Jira automatically allocates to a status). You can search by resolution name or resolution ID (i.e. the number that Jira automatically allocates to a resolution). You can search by priority name or priority ID (i.e. the number that Jira automatically allocates to a priority). You can search by filter name or filter ID (i.e. the number that Jira automatically allocates to a saved filter).
