SQL SELECT statement
The SQL SELECT statement is used to retrieve data from a database. The SELECT statement is one of the most commonly used SQL commands, and it is the foundation for many data analysis and reporting tasks.
SELECT statement Syntax
1SELECT column1, column2, ... columnN 2FROM table_name;
In this syntax,
column1, column2, ... columnN are the names of the columns that you want to retrieve, and
table_name is the name of the table from which you want to retrieve the data.
To select all columns from a table, use the
1SELECT * 2FROM table_name;
SELECT SPECIFIC COLUMN
To select specific columns, simply list the columns you want to retrieve:
1SELECT column1, column2 2FROM table_name;
It's important to note that the order of the columns in the SELECT statement determines the order in which the columns will be displayed in the result set.
The SELECT statement can also be used in combination with various clauses, such as WHERE, GROUP BY, HAVING, and ORDER BY, to further refine the data that is retrieved.
