To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) A stored procedure is typically written in SQL. - This option is incorrect because a stored procedure can be written in various programming languages, not just SQL. However, it is true that SQL is commonly used for writing stored procedures.
Option B) A stored procedure is a named PL/SQL block that can accept parameters. - This option is correct because a stored procedure is a named block of code that can be executed with specified input parameters. It is not limited to PL/SQL; it can be written in other programming languages as well.
Option C) A stored procedure is a type of PL/SQL subprogram that performs an action. - This option is correct because a stored procedure is a type of subprogram that performs a specific action or set of actions. It is not limited to PL/SQL and can be written in other programming languages.
Option D) A stored procedure has three parts: the specification, the body, and the exception handler part. - This option is incorrect because the three-part structure described here is specific to PL/SQL procedures, not stored procedures in general. Stored procedures can have different structures depending on the programming language.
Option E) The executable section of a stored procedure contains statements that assign values, control execution, and return values to the calling environment. - This option is incorrect because it describes the functionality of the executable section of a stored procedure, but it does not fully describe a stored procedure as a whole.
The correct answer is B) A stored procedure is a named PL/SQL block that can accept parameters. and C) A stored procedure is a type of PL/SQL subprogram that performs an action. These options accurately describe the characteristics of a stored procedure.
