With SQL, how do you select all the records from a table named "Persons" where the value of the column "FirstName" starts with an "a"?
The SQL LIKE clause is used to compare a value to similar values using wildcard operators. It is used in a WHERE clause to search for a specified pattern in a column.
There are two wildcards often used in conjunction with the LIKE operator:
% - The percent sign represents zero, one, or multiple characters
_ - The underscore represents a single character
LIKE Syntax is as follows:
SELECT column1, column2, column3,... FROM table_name WHERE column P LIKE pattern;
Tip: You can also combine any number or the multiple numbers of conditions using AND or OR operators.
SQL LIKE Examples:
The following SQL statement selects all Slightbook with a CourseName starting with "H",
SELECT * FROM Slightbook WHERE CourseName LIKE 'H%';
