However, none of the rows is actually retrieved at this point. That will be done by the FETCH statement

What is Embedded SQL in DBMS? Embedded SQL in DBMS is a technique which allows SQL statements to be directly included within the programming languages such as C, C, Java, Python, etc. Basically, the general-purpose programming logic is combined with database operations in a single application. Database management System or DBMS provides some API calls or special syntax that allows developers

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.

Main features of Embedded SQL . Embedded SQL provides several advantages over a call-level interface Embedded SQL is easy to use because it is simply Transact-SQL with some added features that facilitate using it in an application. It is an ANSIISO-standard programming language. It requires less coding to achieve the same results as a call

A SQP environment is the framework under which data exists and SQL operations are executed. Think of a SQL environment as a DBMS running at some installation. So tables, triggers, views, etc are defined within a SQL environment Database servers maintain some number of connections, so app servers can ask queries or perform modifications.

In what order should tables be accessed? What constraints should be checked? Decisions are based on schema, table sizes, etc. Result is a query execution plan.

Programs that contain embedded dynamic SQL statements must be precompiled like those that contain static SQL, but unlike static SQL, the dynamic statements are constructed and prepared at run time. The source form of a dynamic statement is a character string that is passed to Db2 by the program using the static SQL PREPARE or EXECUTE IMMEDIATE
