SQL PL stands for Structured Query Language Procedural Language and was developed by IBM as a set of commands that extend the use of SQL in the IBM DB2 (DB2 UDB Version 7) database system.[1] It provides procedural programmability in addition to the querying commands of SQL. It is a subset of the SQL Persistent Stored Modules (SQL/PSM) language standard. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces.[citation needed]

As of DB2 version 9, SQL PL stored procedures can run natively inside the DB2 process (inside the DBM1 address space, more precisely) instead of being fenced in an external process.[2] In DB2 version 9.7 IBM also added a PL/SQL front-end to this infrastructure (called "SQL Unified Runtime Engine"), meaning that procedural SQL using either the ISO standard or Oracle's syntax compile to bytecode running on the same engine in DB2.[3]
