CREATE MACRO Statement 10316
The CREATE MACRO statement defines a named, callable SQL expression as a database schema object. Macros may declare parameters, which can be referenced by its expression. Once a macro is created, it may be called by referencing its name and ... from one another with a comma. Overloading Macros support overloading: A single CREATE MACRO statement can define multiple implementations (sometimes called 'overloads'), each having its own parameter list, AS keyword, and expression. Note that all of the impl ... ementations are defined in the same CREATE MACRO statement: it is not possible to add, remove, or alter individual implementations after the macro is created. Multiple implementations are separated from one another by a comma. Each implementation must ... have a unique parameter-type signature: that is, in one CREATE MACRO statement, all implementations having the same number of parameters must each have a unique sequence of parameter types - regardless of the parameter na ...

ICU Extension 8951
The icu extension provides collation, time zone, and calendar support. New In DuckDB 2.0, the dependency on the external ICU library was removed. The icu extension now implements collations, time zones, and calendars natively, with time zon ... e data built directly from the IANA Time Zone Database . Behavior is unchanged, and the native implementation is smaller and faster. If you ship a custom build, note that ICU is no longer bundled. Installing and Loading The icu exte ...

Load Extensions 8577
Overview DuckDB-Wasm's (dynamic) extension loading is modeled after regular DuckDB's extension loading, with a few relevant differences due to the difference in platform. A growing subset of core, community, and external extensions is suppo ... he LOAD operation will fetch (and decompress on the fly), perform signature checks and dynamically load via the Emscripten implementation of dlopen . Autoloading Autoloading , i.e., the possibility for DuckDB to add extension functionality on-the-fly, is enabl ... er, which adds both differences and some restrictions relative to native. Instead, DuckDB-Wasm ships a separate JavaScript implementation of the same functionality. Running LOAD httpfs; opts into this re-implemented HTTP stack, which is interchangeable with th ...
