Find out Whether a Value Exists in a List of Values

You can use a normal SELECT query joined with a bunch of AND statements to determine if a certain value exists, but this can become cumbersome and tedious. Enter the IN statement. You could use it like this:

SELECT *  FROM 

   TABLE

 WHERE STUDENTID  IN

(

STU123,

STU456,

STU789,

STU1003,

STU10

)
