Dynamic SQL
If everything is known about a SQL statement when the application is compiled, the statement is known as a static SQL statement.In some cases, however, the full text of a SQL statement may not be known when an application is written. For example, you may need to allow the end-user of the application to enter a SQL statement. In this case, the statement needs to be constructed at run-time. This is called a dynamic SQL statement.
