PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation’s procedural extension language for SQL and the Oracle relational database. PL/SQL’s general syntax resembles that of Ada or Pascal. PL/SQL is one of three key programming languages embedded in the Oracle Database, along with SQL itself and Java.
PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7). Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation.
