Formal pseudo-language for documentation can be embedded in SQL and PL/pgSQL scripts. This documentation is then processed by a documentation generator—an external tool which extracts data and generates hypertext. Since PL/SQL: supports some of these tools, PL/pgSQL is expected to provide full or partial support as well.
PL/SQL is the extended SQL language used by Oracle Database. 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).

Where the injection occurs within a PL/SQL block, an attacker can inject an arbitrary number of queries or statements to execute; escaping special characters and using bind variables ensures the reduced likelihood of XSS and SQL injection vulnerabilities. XSS vulnerabilities arise in APEX applications just like other web application languages ...
The Server Manager Command Line — a replacement of SQL*DBA — is obsolete and SQL Plus 8i and later allows the user to issue statements like STARTUP and SHUTDOWN when connected as SYSDBA. Server Manager 7.1 introduced the command CONNECT / AS SYSDBA to replace CONNECT INTERNAL. [8] SQL Plus 8i and later allows the use of CONNECT / AS SYSDBA
Stored procedure parameters will be treated as data even if an attacker inserts SQL commands. Also, some DBMS will check the parameter's type. However, a stored procedure that in turn generates dynamic SQL using the input is still vulnerable to SQL injections unless proper precautions are taken.
