Report queries are stored in the sql/report_queries folder of the repository. Comments can appear throughout the query to provide instructions or clarifications. Additional keywords may appear after the WHERE keyword to further customize the output of the report. The keyword WHERE specifies the filters that should be applied to limit the rows in the report. After the keyword FROM, there is a list of the tables the fields are coming from. Under the keyword SELECT, you will see a list of the fields that will show up in the final report. The main query determines the final look of the report. Calling them subqueries is meant to emphasize the role they play in the larger query.) (Note: The official term for these parts of the query is common table expressions, or CTEs. These subqueries help simplify and rearrange different parts of the database to make the final query easier. Queries may include several groups of smaller queries, which may be referred to as subqueries. To make things easier for the user, queries typically include a “parameters” section at the top that allows one to easily specify the values needed for filtering on a field. These “comments” often describe basic components of the query and give a brief description of the purpose. Queries may start with a short block of text that is not part of the query. Report queries in the FOLIO Analytics repository are laid out in a particular structure that will make it easy for you to find the various areas you need as you build your knowledge of SQL. Please refere to the version matrix for compatibility. *Releases of FOLIO Analytics are tied to a specific flower release. Using queries from the FOLIO Analytics repository Other sections of the documentation cover administration of derived tables and use of derived tables for ad hoc querying.

The first section below outlines how to make use of the report queries in the FOLIO Analytics repository to generate reports on FOLIO data. How the queries are organized in the repository.

Examples of the software queries can be run in.
These queries are managed behind the scenes through LDP administration so that they run automatically and generate the derived tables in the database. A derived table is simply a table created using data from one or more other tables.

Reports developed for FOLIO are stored as code written in Structured Query Language (SQL). The FOLIO Analytics repository contains reports and other analytics developed for FOLIO and designed to run on the Library Data Platform. FOLIO Analytics What is the FOLIO Analytics repository
