PSQLQueryTool Glossary

Description

In order to make the most of the MSFF PSQL Mars database, you must be familiar with the schema and table layout of the database. The examples, provided here allow you to access to descriptions of the tables and columns available for you to query.

There are two sources for this information in the reference schema:

1. [reference.]pubmars_glossary

   This is a VIEW based on joining several of the postgres control tables which define the actual Mars data tables; this includes tables in the public schema. Field descriptions will be null, if the table author did not populate a descriptive comment about the column.

   Suggested selection-list fields: schema_name, table_name, column_name, datatype_name, description

2. [reference.]glossary

   This is a hand-updated table describing all of the tables under the control of THEMIS Mission-Operations; the descriptions provided here may be more verbose than those in the pubmars_glossary

   Suggested selection-list fields: table_name, field_name, value_type, description

   Suggested constraints: schema_name='thmpub'

The examples provided will get you started; you should refine the constraints-list and the order-by-list according to your needs.
