Flex functions

This section contains helper functions for use in working with flex tables and flexible columns for complex types. You can use these functions with flex tables, their associated flex_table_keys tables and flex_table_view views, and flexible columns in external tables. These functions do not apply to other tables.

For more information about flex tables, see Flex tables. For more information about flexible columns for complex types, see Flexible complex types.

Flex functions allow you to manage and query flex tables. You can also use the map functions to query flexible complex-type columns in non-flex tables.
