Dynamic SQL and Dynamic PL/SQL

Dynamic SQL refers to SQL statements that are constructed and executed at run-time. Dynamic is the opposite of static. Static SQL refers to SQL statements that are fixed at the time a program is compiled. Dynamic PL/SQL refers to entire PL/SQL blocks of code that are constructed dynamically, then compiled and executed.

Ever since Oracle7 Release 1, we PL/SQL developers have been able to use the built-in DBMS_SQL package to execute dynamic SQL . In Oracle8i Database, we were given a second option for executing dynamically constructed SQL statements: native dynamic SQL (NDS). NDS is a native part of the PL/SQL language; it is much easier to use than DBMS_SQL, and, for many applications, it will execute more efficiently.
