Custom Schema Example

This section contains an example of a complete schema that has been automatically generated using the driver's CreateDriverSchema stored procedure. The schema consists of the following parts:

  • The info section enables a relational view of a HarperDB table. For more details, see Custom Schema Definitions.

  • The GET, POST, MERGE, and DELETE methods allow SELECT, INSERT, UPDATE, and DELETE commands to this table. The coreExecOperation operation is an internal implementation and can be copied as-is to your own custom schema file.
