Suppose you have to retrieve some records based on whether a column contains a certain group of characters. As you know, in SQL the WHERE clause filters SELECT results. By itself, WHEREfinds exact matches. But what if you need to find something using a partial match? In that case, you can use LIKE in SQL. This operator searches strings or substring...
If you don’t know the exact pattern you’re searching for, you can use wildcards to help you find it. Wildcards are text symbols that denote how many characters will be in a certain place within the string. The SQL ANSI standard uses two wildcards, percent (%) and underscore (_), which are used in different ways. When using wildcards, you perform a ...
Now we will discuss how to use LIKE in SQL with text-only strings and no wildcards. In some circumstances, you may find that there are better options than using LIKEin SQL pattern matching. But for now, let’s see how this works. We’ll start by looking at the complete table of animal names and ID numbers, as shown below: Note: . ..denotes two spaces...
You can also test for strings that do not match a pattern. To do this, we combine the LIKE and NOToperators. It is another way of performing the SQL pattern matching. In the example below, we want to find all animal names that don’t have an “a” character: Result:
The WHERE clause can include more than one condition. Therefore, LIKE and NOT LIKEcan be used with other operators. Let’s look at another example: Result: It returned all the animal names that start with an “s” character or end with a “g” character.

As you can see, the syntax is quite similar: Let’s see how we can use LIKEto change some animal names. Ready? There is only one record that matches the LIKE %key% condition: monkey. After this update, “ti...
SQL pattern matching is very useful for searching text substrings. LIKE and its close relative NOT LIKE make this quite easy to do. If you are interested in learning more about pattern matching and the LIKE operator, check out the SQL Basics course. It will show you how to build queries from scratch, but it will also introduce practical skills like...
A surprisingly simple and yet powerful one: values without insert. The following select statement can thus be implemented as a standard-conforming values without insert: Instead of a non-conforming select without from: SELECT CURRENT_DATE. the standard allows the use of values without insert: VALUES (CURRENT_DATE)
The SQL WHERE Clause. The WHERE clause is used to filter records. It is used to extract only those records that fulfill a specified condition. Example. Select all customers from Mexico: SELECT * FROM Customers. WHERE Country='Mexico'; Try it Yourself » Syntax. SELECT column1, column2, ... FROM table_name. WHERE condition;
