Procedural SQL Reference

This section contains information about SingleStore Procedural SQL (PSQL), which encompasses stored procedures, user-defined scalar-value functions (UDFs), user-defined table-valued functions (TVFs), and user-defined aggregate functions (UDAFs).

SingleStore also supports Wasm-based functions. Refer to Code Engine - Powered by Wasm for information on creating Wasm-based UDFs and TVFs. To create Wasm-based UDAFs, refer to CREATE AGGREGATE. If your logic and data structures can be implemented in PSQL with reasonable effort in a way that performs well, use PSQL. For integrating more complex logic and data structures, or using existing C/C++ or Rust code, SingleStore recommends using Wasm-based functions.
