As with the UPPER function, you can use the LOWER function in a WHERE clause when you aren t sure about the case of the text you are trying to match. List movies that have the word of in the title, regardless of whether it is capitalized or not. Note the combined use of the LIKE operator and LOWER function. Also note that you must handle special cases where the word of could be the rst word or last word in the title (that is, where it might not have a space before it or after it). These cases don t actually exist in the sample database, but they could, and you cannot simply use LIKE %of% or you might select a title because it had a word like often in it. The lesson here is that you have to know something about what might be in the data in order to write SQL that will always produce the expected result.

The SUBSTR function appears in most SQL implementations, but it sometimes has a somewhat different name. For example, the function is named SUBSTRING in Microsoft SQL Server, Sybase Adaptive Server, and MySQL, while the name SUBSTR is used in Oracle and DB2. It returns a portion of a string as determined by the parameters, which provide the name of the column, rst (starting) position of the column data to be returned, and the number of characters (length) to be returned. And, while it s an unusual use of SUBSTR, a literal string can be provided instead of a column name. The general form of the function is shown rst, followed by an example:

Some people have full middle names in the PERSON table, while others have only a rst initial. List the full name of each person whose last name begins with the letter B in the form of a single string that contains the given ( rst) name, middle initial, and family (last) name. Here is the solution using Oracle:

SELECT PERSON_GIVEN_NAME || ' ' || SUBSTR(PERSON_MIDDLE_NAME, 1, 1) || '. ' || PERSON_FAMILY_NAME AS FULL_NAME FROM PERSON WHERE SUBSTR(PERSON_FAMILY_NAME, 1, 1) = 'B' FULL_NAME ---------------------Beverly V. Baker Gerald M. Bernstein Rose B. Bernstein Steven R. Bernstein 4 rows selected.
Note the use of SUBSTR in the WHERE clause to lter out people with a family name that doesn t begin with B . By now you should be able to think of other ways to do this, including the LIKE operator. Here is the Microsoft SQL Server version of the previous example:
SELECT PERSON_GIVEN_NAME + ' ' + SUBSTRING(PERSON_MIDDLE_NAME, 1, 1) + '. ' + PERSON_FAMILY_NAME AS FULL_NAME FROM PERSON WHERE SUBSTRING(PERSON_FAMILY_NAME, 1, 1) = 'B'

FULL_NAME ---------------------Beverly V. Baker Gerald M. Bernstein Rose B. Bernstein Steven R. Bernstein (4 row(s) affected)
LENGTH
The LENGTH function returns the length of a character string. However, Microsoft SQL Server and Sybase Adaptive Server use the name LEN for their version of the function. Here are some examples: List the length of the movie title for the movie with a MOVIE_ID of 1. Assume an Oracle, DB2, or MySQL database.
SELECT MOVIE_TITLE, LENGTH(MOVIE_TITLE) AS LENGTH FROM MOVIE WHERE MOVIE_ID = 1; MOVIE_TITLE LENGTH ----------------- ---------Mystic River 12
List all movie titles that are shorter than 10 characters in length. Assume a Microsoft SQL Server database.
SELECT MOVIE_TITLE, LEN(MOVIE_TITLE) AS LENGTH FROM MOVIE WHERE LEN(MOVIE_TITLE) < 10; MOVIE_TITLE LENGTH ------------ ---------Big Fish 8 Das Boot 8 Monster 7
