Dynamic SQL is a technique for building and executing SQL statements as strings, while embedded SQL integrates high-level programming languages with database management systems (DBMS) to simplify database interactions. Embedded SQL enhances ease of use, security, frontend-backend integration, and error prevention for developers. Popular DBMS supporting embedded SQL include IBM DB2, Oracle Database, and Microsoft SQL Server.

1. Dynamic SQL

2. • Dynamic SQL is a programming technique you can use to build
SQL statements as textual strings and execute them later. This
technique could prove to be useful in some cases and therefore
it’s good to know we have it as an option.

4. Embedded SQL

5. • Embedded SQL is a powerful method that allows the
integration of high−level programming languages with
database management systems (DBMS).
• It acts as a bridge between applications and databases
which helps in data manipulation and communication.
Various database management systems offer embedded
SQL, giving developers the freedom to select the one that
best serves their requirements.
• Popular DBMS that support Embedded SQL are Altibase,
IBM Db2, Microsoft SQL Server, Mimer SQL, Oracle
Database, PostgreSQL, and SAP Sybase.

6. Need of Embedded SQL
• The goal to make database interactions simpler for
application developers and end users determines the
demand for embedded SQL.
• Users often enter values or submit requests while
interacting with an application, which requires accessing
and changing data contained in a database.
• Developers may conduct these database tasks without
burdening the user with SQL complexities by integrating
SQL queries directly into the application code.

7. Structure of Embedded SQL

8. Advantages of Embedded SQL
• Ease of Database Usage
• Accessing databases is made simple with embedded
SQL, which eliminates the need for lengthy coding or
other programs. It offers a simple method for getting
data by feeding it into the database, doing away with
the need for complex and complicated programming.

9. • Security and authorization
• With embedded SQL, developers may specify and
implement appropriate authorization procedures for
database access. This helps prevent unauthorized
access to sensitive data and ensures that only users
with the proper authorization can execute certain tasks.

10. • Integration of Frontend and Backend
• By permitting a direct connection between the user interface and
the database, embedded SQL makes it easier to integrate the
front end and back end of an application. This improves the
overall user experience by enabling real−time data retrieval and
changes.
• Error prevention
• Developers can prevent logical mistakes from happening when
processing database transactions by integrating SQL queries into
the application code. The integration of SQL with the host
language guarantees security and improves the application's
dependability.
