What Is SELECT (Databases)?

The SELECT statement is comparable to the ideal best friend you have always dreamed of. Being consistent, explicit, and clear is essential, and you would agree that these are the very qualities we seek in our friends. Therefore, let us split it down like this: To begin, you must start with a keyword; in this example, SELECT will serve as the term. The next step is to the columns you intend to incorporate into your query. Use an asterisk (*) after the name of each column to indicate to SQL Server which columns have been selected. This will allow you to structure your data in a specific and consistent manner. As soon as all of the columns you have chosen to include in the statement have been incorporated, we can move on to the FROM clause, where we will list all the data sources (aka our friends). These data sources could be single or composite tables; alternatively, they could be views or subqueries! Hold on—there is more! You can also add an ORDER BY clause at the end of your query so that when you run your SELECT statement against those data sources (also known as friends), it will return the results in a particular order based on the criteria that you specify within the parentheses that follow ORDER. This can be accomplished by adding the clause after your query. Indeed, you have it correct! You are free to include any number of optional provisions. If you do not include a WHERE clause in the query, the results will consist of all data in the table. Your results will be sorted using the default ordering associated with each column if you do not add an ORDER BY clause in your query. The use of optional clauses is analogous to having amazing friends who are never present at your parties. It is wonderful to know they are there even if you are aware that you can invite them and that they will enjoy themselves regardless of whether or not you do so.
