What is a Select Statement for SQL?
SELECT statement for SQL, sometimes referred to as a Query, allows you to retrieve the records you want from the database so that you can manipulate or analyze them further. In this article, we’ll cover how to write a SELECT statement in SQL and look at some examples of how they are used. When writing your own SELECT statement for SQL, it’s important to consider two factors as mentioned below:
- the source (where you are pulling your data from) and
- the columns (which data fields you want).
These can both be changed using clauses in your statement.
What is Select Query
A select query is used to get data from a database. In simple terms, we use it when we need some information from our tables, for example, if we want to view all records of employees who were hired after December 2016 or if we want to see customers who have made more than 10 orders last year. In addition, using Select Query will help us when we need only specific columns from SQL table.
For example, let’s say that we have an Orders table with five columns: OrderDate, CustomerID, EmployeeID, ProductID, and Quantity. Now let’s assume that we only want to display records where EmployeeID = 2; thanks to Select Query we will be able to do just that without displaying other four fields.
SELECT * FROM Table
This is used to retrieve all of your data from your database. If you want to only get certain columns you would put SELECT columnname1, columnname2, etc.
