(The internal H2 database and Custom Report feature have been removed from Synthea for performance reasons. This page is left for historical reference only)

Synthea allows for the creation of custom reports each time a population is generated, using the CustomSqlReport class. This class uses the internal H2 data store to run arbitrary SQL queries against. These queries are defined in a configurable SQL file, and the results are exported in CSV format to ./output/reports/. Currently only SELECT statements are allowed in the SQL.

The Synthea DataStore uses an H2 database under the hood, so any queries must be valid H2-style syntax. See H2 Database Functions for more information on what functions are available.

Configuration Settings

• generate.database_type : REQUIRED: Set to in-memory or file to enable the database against which the queries will be run
• exporter.custom_report : Set to true to enable the custom reports. Defaults to false.
• exporter.custom_report_queries_file : Set this to the location of an SQL file (relative to src/main/resources) containing queries to run at each population generation. Defaults to custom_queries.sql (aka src/main/resources/custom_queries.sql)

Sample Queries

(Note: these queries have been formatted for readability. Currently the report generator requires that all queries be contained on a single line.)

Sample Query 1: select everything from the "person" table.

select * from person;

Sample Query 2: select the number of living people.

select count(*) from person where person.DATE_OF_DEATH is null;

Sample Query 3: select the people that have an active diagnosis of diabetes, along with the age of diagnosis

SELECT p.name, p.gender, 
  DATEADD('MILLISECOND', p.DATE_OF_BIRTH, DATE '1970-01-01') DOB, 
  DATEADD('MILLISECOND', c.start , DATE '1970-01-01') onset_date, 
  DATEDIFF('YEAR', 
      DATEADD('MILLISECOND', p.DATE_OF_BIRTH, DATE '1970-01-01'), 
      DATEADD('MILLISECOND', c.start, DATE '1970-01-01')) age_at_diagnosis
FROM PERSON p, CONDITION c 
WHERE p.ID = c.PERSON_ID 
AND c.code = '44054006';
