A personal query is defined and saved by you, and then stored in the Personal folder. If you use the same query over and over again, save it with your preferred format to create a report in your Personal folder.
If you have many different queries to manage, you can create folders in your personal folder. For example, if you construct prompting queries, you can save them in a separate folder named Prompting in your personal folder. Saving queries in your personal folder makes them easier to find and manage.
A shared query is created by one user and is available to all users through the Shared folder (or subfolder).
A system query is either defined and shipped as part of the product, or was customized at your site and stored in the System folder. You can run these queries as is, or you can make a personal copy based off the System query. Any query you save is saved in your Personal folder (or Subfolder).
A custom query has prompts that you must respond to before you can run the query. After making selections as required, you can proceed with the query process. Custom queries are stored in the Custom folder.
A CM build query is defined and shipped as part of the product. These queries are stored in the CM Build Queries folder.
After generating a query, you can easily modify it by changing the fields that are queried for. Additionally, you can change the look of the output by using a different format. You can also share a query with others.
If you are logged on to the central CR database, you can query or report on CRs only. The central CR database does not contain tasks. Tasks that are found using a top-level task query exist in the current development database only.
