SELECT WHERE LIKE Mysql Query

Discussion in 'MySQL' started by Weirfire, Mar 8, 2006.

  1. #1
    Using the following example table;
    SEMrush
    tablea

    field1 - roger rabbit
    field2 - cartoon

    I want to extract all the rows from table a where field 1 contains the name roger. At the moment I have a query set up like this

    SELECT * FROM tablea WHERE "roger" LIKE '%field2%'

    but this returns nothing.

    Only when I set field 1 to just "roger" do I get it to return any rows.

    What am I doing wrong with my query? :)

    Show us the column headings and one or two rows of sample data. You're confusing me with the way you posted it.

    "SELECT * FROM tablea WHERE field2 LIKE '%roger%'"
    
    PHP:
    It looks like you just had your query backwards

    But then is that not effectively saying

    SELECT * FROM tablea WHERE "roger rabbit" LIKE '%roger%' which would give no results because "roger rabbit" doesnt exist within the LIKE variable.

    I'll try and explain it more clearly for T0PS benefit :)


    I have a table which has several fields;

    e.g.

    cartoon_characters
    ----------------------------------------------------
    |name | age | description |
    ----------------------------------------------------
    |roger rabbit | 12 | a silly rabbit |
    ----------------------------------------------------
    |donald duck | 13 | a quacky duck |
    -----------------------------------------------------

    And basically I want all the cartoon characters that have the name "roger" somewhere in the table which is why I would like to use the LIKE option.

    So if I have a query;

    SELECT * FROM cartoon_characters WHERE "roger" LIKE '%name%'

    what am I doing wrong with the query?

    You should use it the way jestep suggested it. It should work then.

    I think I know what your saying and you can't do it the way you're trying. You'll need to split your where clause a bit like
    
    SELECT 
         * 
    FROM 
        cartoon_characters 
    WHERE 
         "name" LIKE '%roger%' or "name" LIKE '%robert%'
    
    Code (sql):
    So in your PHP you'll build the where clause depending on how many words you need. You may also want to look at full text indexing for both performance and ease. I'm getting a strong sense of deja vu here :)

    Yeah I love that full text index with MySQL v5

    Unfortunately the server uses MySQL v4 and won't upgrade. :mad:


    Thanks for the help :)

    Hi savani,
    You want to retrieve all names that contain "y"
    try this
    select * from Table1 where name like '%y%'
