Query Overview

Queries give you an unprecedented level of power and control over your data. Because of Open Dental’s MySQL database, you have access to all of your data and can create custom queries to generate reports in any format and export any data you want. Your data is no longer locked inside a proprietary black box. If you can imagine it, Open Dental can do it.

Open Dental has a few built in queries to list tables and hundreds of Query Examples that can be copied and pasted for use. You can also write your own queries, or we can write Custom Queries for you. Save your Favorite Queries for quick access.

See Run a Query for detailed how-to instructions.

To combine multiple queries together or to query multiple databases at once, Excel Queries can be used.

How Queries Work
Open Dental uses an SQL (Structured Query Language) database. The simplest query statement looks like this: SELECT * FROM fee; In English, this statement means "show all columns from the table called fee". The result looks similar to a spreadsheet document. The query returns only the information you specify (select) in your query statement. 

In Open Dental, most tables are named in the singular rather than plural because they describe the data a single row holds. So the 'fee' table is not named 'fees' because 'fee' is a more accurate description of the information contained in one row.

Using SQL for querying data allows the user to perform many built-in functions, including:

  • Specify the columns to display and the order and names of columns.
  • Filter out rows that do not fit your criteria.
  • Order the rows by whichever column you wish
  • Add columns that are formed using mathematical formulas that operate on other columns.
  • Get aggregated results from multiple tables at once.
