![]() ![]() The query will match both lowercase and uppercase records. By default, the LIKE query returns case-insensitive results. In MySQL, the LIKE statement is used to find records with incomplete strings. To find case sensitive or insensitive data, add a new collation to your select query. NOT LIKE is similar to LIKE in that it excludes data rather than incorporating it.įor instance, if we wanted to observe all the non-brown cats that came through the center, we could construct a query like this: The NOT LIKE operator can also be used to locate records that do not fit the pattern you specify. For example, the following query matches companies like 'DataCamp', 'DataComp', and so on: SELECT name The _ wildcard will match a single character. The underscore _ which can be used singularly or in multiples to represent a certain number of characters, is a wildcard for indicating the presence of a single character.Įxample 1: If we wanted to see the outcome data for all the wolfhounds and wolfhound mix dogs that passed through the animal center we could write the query like this: SELECT monthyear,Įxample 2: following query matches companies like 'Data', 'DataC' 'DataCamp', 'DataMind', and so on: SELECT name The wildcard % is used to replace all potential strings in the search string at its location. LIKE accepts two wildcards, and _ which denote all characters or a single character, respectively. With LIKE, you have two wildcard options: ![]() To do so, you utilise a wildcard as a placeholder for certain additional variables. To find a pattern in a column in SQL, use the LIKE operator in the WHERE clause. Case is unimportant in LIKE and NOT LIKE searches. The LIKE and NOT LIKE expressions allow you to declare a list of comparable values that should be returned or excluded from the results of a query. Similarly, you may wish to exclude data from a query yet want to exclude it in numerous distinct ways in the original table. Data is frequently untidy and inconsistent, yet you still want to be able to identify and use it, even if values that represent the same thing are written somewhat differently and thus do not match perfectly from row to row in a table.
