Procedural Data Manipulation Languages (DML) are programming languages used to perform operations on data within a database. Unlike declarative languages, which specify what data to retrieve or manipulate, procedural DML focuses on how to accomplish these tasks through a series of commands or procedures. Examples include SQL procedural extensions like PL/SQL and T-SQL, which allow for control structures, loops, and variables to manage data effectively. This approach enables developers to write complex logic and automate data manipulation tasks within their applications.

What is the difference between procedural and non-procedural languages?
AnswerProcedural languages are used in the traditional programming that is based on algorithms or a logical step-by-step process for solving a problem.A procedural programming language provides a programmer a means to define precisely each step in the performance of a task Non-procedural programming languages allow users and professional programmers to specify the results they want without specifying how to solve the problem. examples are FORTRAN,C++,COBOL,ALGOL etcOR we can put it this way:Procedural language determines WHAT & HOW a process should be done, Non-procedural language is concerned with the WHAT not the HOW. Non-proc languages are those languages where you specify what conditions the answer should satisfy, but not how to obtain it.
What is the significance of considering the size of types in programming languages?
Considering the size of types in programming languages is important because it affects how much memory is used and how data is stored. It can impact the efficiency and performance of a program, as well as the range of values that can be represented. By understanding and managing type sizes, programmers can optimize their code and prevent errors related to data storage and manipulation.
Is processing the manipulation by which a computer transforms data into information?
yes
What are the drawbacks of procedure oriented programming languages?
Procedural programming is when an application executes a series of procedures. In procedural programming, the user is unable to choose what the program does next. In OOP (Object oriented), the user can click on any button they want, but in procedural, it just executed the pre-set procedures, then ends.
Involves the manipulation of data to eliminate rows according to certain criteria?
Selecting
What is the difference between Procedural DMLs and Declarative DMLs?
Procedural DMLs (Data Manipulation Languages) require the user to specify a sequence of operations to manipulate data, allowing for more control and flexibility in how tasks are executed. In contrast, Declarative DMLs focus on what data to retrieve or manipulate without detailing the steps to achieve it, making them generally easier to use. Examples include SQL for Declarative DMLs, while Procedural DMLs can include languages like PL/SQL or T-SQL. The choice between them often depends on the complexity of the operations and the level of control needed by the developer.
Is a query language a procedural language?
No, a query language is not a procedural language. Query languages are used to retrieve specific information from databases or other data sources by defining and executing queries, while procedural languages are used to write algorithms and executable instructions to solve problems.

The types of languages a database system?
Database systems can support multiple types of languages, including data definition language (DDL) for defining database schema, data manipulation language (DML) for querying and updating data, and data control language (DCL) for managing access and permissions. Additionally, some database systems support procedural languages like PL/SQL or T-SQL for writing stored procedures and triggers.
What is the difference between a procedural and a non-procedural language IN DBMS?
In a procedural language, like PL/SQL, the programmer specifies the steps to be taken to accomplish a task, while in a non-procedural language, like SQL, the programmer specifies what needs to be done rather than how to do it. In the context of a DBMS, procedural languages are used for developing complex logic and operations within the database, while non-procedural languages are used for querying and manipulating data.
What is the difference between Procedural DMLs and Declarative DMLs.?
Procedural DMLs (Data Manipulation Languages) allow users to specify how to perform operations on data, providing control over the execution process through programming constructs like loops and conditionals. In contrast, Declarative DMLs focus on what data to retrieve or manipulate without detailing how to achieve it, allowing the database management system to determine the best execution plan. Essentially, procedural DMLs require explicit instructions for processing, while declarative DMLs emphasize the desired outcome. Examples include SQL as a declarative language, and PL/SQL as a procedural extension of SQL.
What are the three languages were adopted by the DBTG?
The three languages adopted by the Database Task Group (DBTG) were Data Definition Language (DDL), Data Manipulation Language (DML), and Data Control Language (DCL). These languages formed the basis for standardized data management within the DBTG framework.
What is sql and plsql?
SQL stands for Structured Query Language, and is a computer language designed for writing data manipulation or data management statements against a relational database. PL/SQL stands for Procedural Language/Structured Query Language which is Oracle's proprietary procedural extensions to the SQL language.
What statement belong in a procedural languages but not in a non procedural language?
Assignment operator
What are the 3 languages adopted by DBTG?
The three languages adopted by the Database Task Group (DBTG) are Data Definition Language (DDL), Data Manipulation Language (DML), and Data Control Language (DCL). These languages help define the structure of databases, manipulate data within databases, and control access permissions to the data.
What is data manipulation called?
Data manipulation refers to the process of adjusting, organizing, or transforming data to make it more useful for analysis or visualization. This can involve operations such as sorting, filtering, aggregating, or modifying data. In the context of databases, it is often performed using languages like SQL, which facilitate the retrieval and modification of data. Overall, effective data manipulation is essential for deriving insights and making informed decisions.
WHAT ARE Declarative DMLs?
Declarative Data Manipulation Languages (DMLs) are programming languages that allow users to specify what data to manipulate without detailing how to perform the operations. They focus on the desired outcome rather than the procedure, enabling simpler and more intuitive data interactions. SQL (Structured Query Language) is a prime example, where users can execute commands like SELECT, INSERT, UPDATE, and DELETE to manage data in relational databases. This contrasts with imperative DMLs, which require detailed procedural steps to achieve the same results.
