Question

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)
