Self-Instruct
Dynamic SQL and Embedded SQL are two different types of Structured Query Language (SQL) statements. Dynamic SQL is a type of SQL statement that is created and executed at runtime, while Embedded SQL is a type of SQL statement that is embedded into an application program.
Dynamic SQL is used when the SQL statement is not known until runtime, and can be used to create and execute SQL statements on the fly. It is often used in applications where the user needs to be able to create their own SQL queries. Dynamic SQL is also used in situations where the SQL statement needs to be generated based on user input.
Embedded SQL is used when the SQL statement is known at compile time, and is embedded into the application program. It is often used in applications where the SQL statement is fixed, and the user does not need to be able to create their own SQL queries. Embedded SQL is also used in situations where the SQL statement needs to be generated based on application logic.
Dynamic SQL is more flexible than Embedded SQL, as it allows the user to generate and execute SQL statements on the fly. However, it is more difficult to debug and maintain than Embedded SQL, as the SQL statement is not known until runtime.
Embedded SQL is less flexible than Dynamic SQL, as the SQL statement is known at compile time. However, it is easier to debug and maintain than Dynamic SQL, as the SQL statement is known at compile time.
In summary, Dynamic SQL is used when the SQL statement is not known until runtime, and Embedded SQL is used when the SQL statement is known at compile time. Dynamic SQL is more flexible than Embedded SQL, but is more difficult to debug and maintain. Embedded SQL is less flexible than Dynamic SQL, but is easier to debug and maintain.
