Oracle SQL Queries: A Beginner’s Guide

To execute a query in the Oracle database, you can use SQL statements. Here is a simple example:

SELECT * FROM table_name;

In this query, “table_name” is the name of the table you want to query. This will return all the columns and data in the table.

You can also use conditions to filter the results of the query, for example:

SELECT * FROM table_name WHERE column_name = 'value';

This will return the rows in the table that meet the condition where “column_name” is the name of the column you want to filter on, and “value” is the value you want to match.

In addition to the SELECT statement, you can also use other SQL statements such as INSERT, UPDATE, and DELETE to perform different operations.

Please note that before executing the query, you need to make sure you have the proper permissions to access the database and tables.
