Mastering SQL Fundamentals for Oracle Database
To fully use the Oracle Database, knowing SQL basics is key. This part will cover the main ideas of SQL data types, operators, query syntax, and key clauses. It will help you manage and change data in the Oracle system well.
SQL Data Types and Operators
SQL data types are the basics for storing info in the database. They range from VARCHAR2 for text to NUMBER for numbers. Knowing these types is vital for keeping data right and making it run fast. SQL operators like +, -, *, /, =, >, =, != are also key. They let you do math, compare, and logical stuff with your data.
SQL Query Syntax and Clauses
SQL is all about getting, changing, and managing data efficiently. The query syntax, with clauses like SELECT, FROM, WHERE, GROUP BY, ORDER BY, JOIN,, lets you make strong queries. These queries can pull, filter, and group data from the Oracle Database. Learning these SQL clauses is key to using the Data Manipulation Language (DML), Data Definition Language (DDL), and Data Control Language (DCL) in Oracle.
| SQL Fundamental Concept | Description |
|---|---|
| SQL Data Types | Diverse data types like VARCHAR2, NUMBER, DATE, etc. for storing information |
| SQL Operators | Arithmetic, comparison, and logical operators for data manipulation |
| SQL Query Syntax | The structure of SQL queries, including clauses like SELECT, FROM, WHERE, etc. |
| Data Manipulation Language (DML) | Statements for inserting, updating, deleting, and querying data |
| Data Definition Language (DDL) | Statements for creating, modifying, and dropping database objects |
| Data Control Language (DCL) | Statements for managing user permissions and access control |
