So what i need is a query or some tip on how to turn all titles on a wordpress powered website into capitalized case.

What i have now is something like this:

AAAAA BBBBB CCCCC

I want it to be like this:

Aaaaa Bbbbb Ccccc

I did try googling and searching here, but have failed at that task so any help is much appreciated!

UPDATE:

I need to update titles inside the database. Just to be clear. 🙂

    There is no function in MySQL for this, but you can create one like this:

    DROP FUNCTION IF EXISTS proper;
    SET GLOBAL  log_bin_trust_function_creators=TRUE;
    DELIMITER |
    CREATE FUNCTION proper( str VARCHAR(128) )
    RETURNS VARCHAR(128)
    BEGIN
      DECLARE c CHAR(1);
      DECLARE s VARCHAR(128);
      DECLARE i INT DEFAULT 1;
      DECLARE BOOL INT DEFAULT 1;
      DECLARE punct CHAR(17) DEFAULT ' ()[]{},.-_!@;:?/';
      SET s = LCASE( str );
      WHILE i < LENGTH( str ) DO 
        BEGIN
          SET c = SUBSTRING( s, i, 1 );
          IF LOCATE( c, punct ) > 0 THEN
            SET BOOL = 1;
          ELSEIF BOOL=1 THEN 
            BEGIN
              IF c >= 'a' AND c <= 'z' THEN 
                BEGIN
                  SET s = CONCAT(LEFT(s,i-1),UCASE(c),SUBSTRING(s,i+1));
                  SET BOOL = 0;
                END;
              ELSEIF c >= '0' AND c <= '9' THEN
                SET BOOL = 0;
              END IF;
            END;
          END IF;
          SET i = i+1;
        END;
      END WHILE;
      RETURN s;
    END;
    |
    DELIMITER ;
    

    From here.

    The you can update easily by running:

    Update wp_posts
    Set post_title = proper(post_title)
