I have a column saved as LONGTEXT on mysql. This text saves rich text. I'm currently reading all the text then fixing it using javascript to get the first 100 characters in a way not to split the word in its middle.
Yet this way don't seem the best way to do it. I want to select a summary directly using the query, yet I also want to be careful not to include characters that are html tags.
The function below seems working fine to strip the html.
SET GLOBAL log_bin_trust_function_creators=1;
DROP FUNCTION IF EXISTS fnStripTags;
DELIMITER |
CREATE FUNCTION fnStripTags( Dirty varchar(4000) )
RETURNS varchar(4000)
DETERMINISTIC
BEGIN
DECLARE iStart, iEnd, iLength int;
WHILE Locate( '<', Dirty ) > 0 And Locate( '>', Dirty, Locate( '<', Dirty )) > 0 DO
BEGIN
SET iStart = Locate( '<', Dirty ), iEnd = Locate( '>', Dirty, Locate('<', Dirty ));
SET iLength = ( iEnd - iStart) + 1;
IF iLength > 0 THEN
BEGIN
SET Dirty = Insert( Dirty, iStart, iLength, '');
END;
END IF;
END;
END WHILE;
RETURN Dirty;
END;
