Flex Extractor Functions Reference

The following extractor scalar functions process polystructured data: 

• MAPDELIMITEDEXTRACTOR
• MAPJSONEXTRACTOR
• MAPREGEXEXTRACTOR

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.
