In this case, % is referred to as a "wildcard." In the type of SQL that Mode uses, LIKE is case-sensitive, meaning that the above query will only capture matches that start with a capital "S" and lower-case "noop. The % used above represents any character or set of characters. In general, putting double quotes around a word or phrase will indicate that you are referring to that column name. One significant difference between LIKE / RLIKE and the full-text search predicates is that the former act on exact fields while the latter also work on analyzed fields. The underscore sign () represents one, single character. There are two wildcards often used in conjunction with the LIKE operator: The percent sign () represents zero, one, or multiple characters. Their syntax is identical, but LIKE is case-sensitive, while ILIKE is case-insensitive. The LIKE operator is used in a WHERE clause to search for a specified pattern in a column. The double quotes (as opposed to single: ') are a way of indicating that you are referring to the column name "group", not the SQL function. LIKE and ILIKE allow pattern matching within character-based column data. By including the LIKE keyword in a WHERE clause, you can search for specific string patterns. You can use these SQL commands via phpMyAdmin on our Cloudways Alternative hosting plans. LIKE is case sensitive, ILIKE is case insensitive. Note: "group" appears in quotations above because GROUP is actually the name of a function in SQL. The LIKE keyword has been a top Azure Cosmos DB feature request and many use cases will see tremendous value from new string search options in Azure Cosmos DB. The predicates LIKE and ILIKE are used to search for strings that match a given pattern, so you can search or for a single word (or string) in a long text field. Run the code to see which results are returned. In this example, the results from the Billboard Music Charts dataset will include rows for which "group" starts with "Snoop" and is followed by any number and selection of characters. LIKE is a logical operator in SQL that allows you to match on similar values rather than exact ones. This is intended as a general, academic question, and so should not matter which DB, but it arose using SQL Server 2005. In this case it would seem to me that 'like' would have an advantage, all other things being equal. Starting here? This lesson is part of a full-length tutorial in using SQL for Data Analysis. 'Like' should only need to test the first three chars to find a match, whereas '' must compare the entire string.
