Introduction Data types in Dremio fall into two categories: primitive types such as INT and VARCHAR that hold single values, and semi-structured types like LIST, STRUCT, and MAP that hold complex values. Arrays are lists of arbitrary size of any single type, indexed by non-negative integers, and are useful for holding sparse data. Note: LIST […]
Introduction User-defined functions (UDFs) are callable routines that make it easier for you to write and reuse SQL logic across queries. In Dremio, you can use UDFs as row-access and column-masking policies. Dremio Cloud and Dremio Software v24.1+ allow you to run subqueries from UDFs. Subqueries are queries nested inside other queries and are often […]
Introduction User-defined functions (UDFs) are callable routines that make it easier for you to write and reuse SQL logic across queries. In addition, UDFs let you extend the capabilities of Dremio SQL, provide a layer of abstraction to simplify query construction, and encapsulate business logic. UDFs can also serve as row and column policies for […]
