SELECT Command in SQL
The SELECT command in SQL is used to retrieve data from a database. It is one of the most commonly used SQL commands and allows users to extract specific information from one or more tables in a database.
Key Points:
- The SELECT command is followed by a list of columns or '*' to indicate all columns to be retrieved.
- Users can specify conditions using the WHERE clause to filter the data that is returned.
- The SELECT command can also be used with functions like COUNT, SUM, AVG, etc., to perform calculations on the retrieved data.
- It is important to note that the SELECT command does not modify the data in the database; it only retrieves it for viewing or further processing.
Using the SELECT command in SQL is essential for querying databases to extract the required information for analysis, reporting, or any other data-related tasks.
