It's pretty easy to create your own string functions for many examples listed here## Count substrings CREATE FUNCTION substr Count(x varchar(255), delim varchar(12)) returns intreturn (length(x)-length(REPLACE(x, delim, '')))/length(delim); SELECT substr Count('/this/is/a/path', '/') as count;## Split delimited strings CREATE FUNCTION str Split(x varchar(255), delim varchar(12), pos int) returns varchar(255)return replace(substring(substring_index(x, delim, pos), length(substring_index(x, delim, pos - 1)) 1), delim, '');select str Split("aaa,b,cc,d", ',', 2) as second;##Or a more complicated example, this will repeat an insert after every nth position.drop function insert2; DELIMITER //CREATE FUNCTION insert2(str text, pos int, delimit varchar(124)) RETURNS text DETERMINISTICBEGIN DECLARE i INT DEFAULT 1; DECLARE str_len INT; DECLARE out_str text default ''; SET str_len=length(str); WHILE(i SET out_str=CONCAT(out_str, SUBSTR(str, i,pos), delimit); SET i=i pos; END WHILE; -- trim delimiter from end of string SET out_str=TRIM(trailing delimit from out_str); RETURN(out_str); END//DELIMITER ;select insert2("ATGCATACAGTTATTTGA", 3, " ") as seq2; NULL) returns 0 (zero) if the field is not null and 1 (one) if the field is null.DELIMITER //DROP FUNCTION IF EXISTS get_mcv; CREATE FUNCTION get_mcv (list text(10000)) RETURNS text(1000)BEGIN DECLARE cnt int(10); DECLARE iter_cnt int(10); DECLARE item text(100); DECLARE f_item text(100); DECLARE prv_cnt int(10) default 0; DECLARE nxt_cnt int(10) default 0; IF list=' ' THEN RETURN list; END IF; select substr Count(list,',') 1 into cnt; SET iter_cnt = 1; while cnt --------------------------------------------------- | get_mcv("dsfds,dsfds,fdfds,dfdsf,sd,df,df,df,df") | --------------------------------------------------- | df | --------------------------------------------------- A field may contain delimited values that may be used with ' IN' operator in a where clause.

You may use my solution from below which is also keeping the order of substring occurance:(input string is stored in "input" variable) CREATE TEMPORARY TABLE temp (id TINYINT NOT NULL auto_increment, val CHAR(20), PRIMARY KEY(id)); SET input=REPLACE(input, ",", "'),('"); SET @dyn_sql=CONCAT("INSERT INTO temp (val) VALUES ('",input,"');"); PREPARE s1 FROM @dyn_sql; EXECUTE s1; SELECT * FROM temp; Hope this would help someone :) In response to Denis Roy on November 15 2007 pm That is a great example.

Here is how I used a very similar example to find a contact's last name from a contacts database by sub string on the last instance of the space: SELECT @string:=Full_Name, SUBSTRING(@string, LENGTH(SUBSTRING(REVERSE(@string), LOCATE(" ", REVERSE(@string))-1))) AS Last_Name FROM contacts; Something that would more elegant would be to have the LOCATE function include a direction option, like: SELECT SUBSTRING(foo, LOCATE(" ", foo, RIGHT)) AS bar; dudes & dudettes,if you want to find the last occurrence of a particular string, use the tools mysql provides for you:select reverse( substring( reverse( field ), locate( 'xyz', reverse( field ) ) 1 ) )---this is way easier to implement and debug As i was in charge to support soundex compatible string comparison i had made following first mysql function.

This function implements the original Soundex algorithm, not the more popular enhanced version (also described by D. The difference is that original version discards vowels first and duplicates second, whereas the enhanced version discards duplicates first and vowels second.

Reverses the reverse and returns 'domain.com'. Perhaps there is a better/fast/easier way, however it's not easily found. [name withheld], you could extract the domain in two simpler ways: SELECT SUBSTRING_INDEX(email,'@',-1) AS domain FROM TABLE -- returns everything to the right of the rightmost @SELECT SUBSTRING(email, INSTR(email,'@') 1) AS domain FROM TABLE -- returns everything to the right of the leftmost @Both will return identical results on email addresses, since they only have one @ in them.

CREATE FUNCTION substr Count(s VARCHAR(255), ss VARCHAR(255)) RETURNS TINYINT(3) UNSIGNED LANGUAGE SQL NOT DETERMINISTIC READS SQL DATABEGIN DECLARE count TINYINT(3) UNSIGNED; DECLARE offset TINYINT(3) UNSIGNED; DECLARE CONTINUE HANDLER FOR SQLSTATE '02000' SET s = NULL; SET count = 0; SET offset = 1; REPEAT IF NOT ISNULL(s) AND offset delimiter ; Use like this: SELECT substr Count('/this/is/a/path', '/') `count`;`count` would return 4 in this case.Can be used in such cases where you might want to find the "depth" of a path, or for many other uses.This function uses string Split and substr Count - thanks to Chris Stubben.
