Sql

An overview of the benefits and limitations of using Relational Database Management Systems (RDBMS).

The DELETE statement is your SQL cleanup crew, removing unwanted rows from a table with precision! 🧹 Use the WHERE clause to target specific rows or wipe out everything (while keeping the table structure intact). Perfect for maintaining data, clearing outdated records, or enforcing business rules. Dive in for a sample query to see DELETE in action! 💥

SQL data types define the kind of values that can be stored in a column and determine how the data is stored, processed, and retrieved. 📊 Discover common types like numeric, character, date/time, binary, and boolean, and learn why choosing the right type is key to optimizing storage and boosting query performance! 🔍

The INSERT statement is your ticket to adding new data to a database table! 🚀 Whether using INSERT INTO for a full row or specifying columns with INSERT INTO table_name (column1, column2, ...), it’s the key to growing your data. Dive in for a sample query to see it in action! 💾

SQL keywords are reserved words that have special meanings within SQL statements. These include commands (like SELECT, INSERT, UPDATE), clauses (such as WHERE, GROUP BY, HAVING), and other syntax elements that form the structure of SQL queries. Understanding SQL keywords is fundamental to writing correct and effective database queries.
