What request for specific data from a database?
A query is a request for specific data from a database. It is written in a structured query language (SQL) and is used to retrieve information based on specific criteria or conditions defined in the query. The query command searches the database for records that match the criteria specified in the query and returns the results in a structured format.
What is the purpose of generating Reports?
If you want a report to only use certain fields, and particularly if you want it to work with only some records that meet a criteria, it is better to create a query to extract what you want first and base the report on that. You can also include multiple tables and calculated fields in a query easier than trying to do it in a report. It is better to get a query to do the work of extracting fields, records and using criteria than trying to do it in a report. So it is a common thing to create queries for the purpose of extracting the data you want for a report.
