SqlCommandSELECT

SqlCommandSELECT is a fundamental operation in SQL (Structured Query Language), used to retrieve data from a database. It is part of the Data Manipulation Language (DML) and is executed using the SELECT statement. The basic syntax of a SELECT statement is as follows: SELECT column1, column2, ... FROM table_name WHERE condition;. This statement retrieves specified columns from a table where the condition is met. If no condition is specified, all rows are retrieved. The SELECT statement can also include clauses such as ORDER BY to sort the results, GROUP BY to group rows that have the same values in specified columns, and HAVING to filter groups based on a condition. Additionally, the DISTINCT keyword can be used to return only distinct (different) values. SqlCommandSELECT is widely used in various applications, including web development, data analysis, and reporting, to fetch and manipulate data efficiently.
