Flex Extractor Functions Reference

The extractor scalar functions process polystructured data:

Each function accepts input data that is:

  • Existing database content
  • A table
  • Returned from an expression
  • Entered directly

These functions do not parse data from an external file source. All functions return a single VMap value. The extractor functions can return data with NULL-specified columns.

This section describes each extractor function.
