The BETWEEN operator is often used in the WHERE clause of the SELECT statement to form the search condition for the rows returned by a query. The LIKE operator is used in a WHERE clause to search for a specified pattern in a column. Use the following wildcard characters to search for and list DB2 objects: _ (underscore) matches any single character. % (percent sign) or * (asterisk) matches a string of zero or more characters. Example 1: Assume that FIRSTNME is a VARCHAR(12) column that contains 'ETHEL' for employee 280. The following query returns the value 5: SELECT LENGTH(FIRSTNME) FROM DSN8A10.EMP WHERE EMPNO = '000280'; We simply don't know what it is, so almost all comparisons will fail. You can use IS NULL and IS NOT NULL, two special operators designed to work with NULL.
