Line 1: {{Primary sources\|date=November 2009}} '''SQL PL''' stands for [[SQL\|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]] (DB2 UDB Version 7) database system.<ref>[https://www.ibm.com/support/knowledgecenter/en/SSEPGG_11.1.0/com.ibm.db2.luw.apdv.sqlpl.doc/doc/c0011916.html IBM Knowledge Center]</ref> It provides [[procedural programming\|procedural programmability]] in addition to the querying commands of SQL. It is a subset of the SQL Persistent Stored Modules ([[SQL/PSM]]) language standard. As of DB2 version 9, SQL PL [[stored procedure]]s can run natively inside the DB2 process (inside the DBM1 address space, more precisely) instead of being fenced in an external process.<ref name="Mullins2012">{{cite book\|author=Craig S.
