What is dynamic SQL, and how does it differ from static SQL?

Program Plan Intro

SQL:

  • The full form of SQL is “Structured Query Language”.
  • SQL is not a programming language. It is text-based and it is also called as data sublanguage.
    • In order to get SQL as a complete programming language, it should be included in scripting languages like Java, C#, and so on.
  • Some of the DBMS products provide GUI tools in order to perform tasks are as follows:
    •  SQL Server
    • Oracle Database
    • MySQL

Importance of SQL:

  • SQL language is used to work with database like defining and processing it. They are executed using DBMS-supplied command prompt.
  • They can control redundant data and also it can restrict unauthorized access.

Explanation of Solution

Dynamic SQL:

  • When the SQL statements get generated at the runtime is called as dynamic SQL.
  • The ad hoc queries are being responded when the SQL statements are generated at the run time by the program.
  • Since the SQL statements are generated at the dynamic SQL environment that is at the run time, the programmer or the end user will not exactly know in which way the queries are generated and how they are being structured.
  • Creation of general purpose and flexible application are made using dynamic SQL because the SQL statement is generated at run time and their complete structure of SQL statements are not known.
  • The attribute and condition values are not known until the user specifies its value.
  • The input is built by the end user and the same program multiple times in generating different outputs...
