I've changed all database command such as select delete alter, ... to yes into my MySQL database manager. I am using directAdmin v1.41.1.
I would try to GRANT permissions to that user ID and client IP and see if that helps.

I have two tables, first called list_city contain list of city in Europe, example:
=========================
= ID = CITY = COUNTRY =
=========================
= 1 = LONDON = UK =
= 2 = PARIS = France =
= 3 = ROME = Italy =
=========================
and the second one is data_customer, contain id_cust and city (but in mess typing)
====================
= ID_CUST = CITY =
====================
= 012AGH = paris =
= 2X4BV = London =
= M3RT45 = romE =
= 1F546 = Lndon =
= 345GC = PArs =
= 54A78 = roma =
====================
How I can matching in the city in the second table with the city in the first table in mysql so the output will be:
====================
= ID_CUST = CITY =
====================
= 012AGH = PARIS =
= 2X4BV = LONDON =
= M3RT45 = ROME =
= 1F546 = LONDON =
= 345GC = PARIS =
= 54A78 = ROME =
====================
I tried
SELECT c1.ID_CUST, c2.CITY FROM data_customer c1 INNER JOIN list_city c2
ON c1.CITY LIKE concat('%',c2.CITY,'%');
But, It's seem not work as Iexpected. It's possible do it only in mysql? If not can anyone give me another solution? Thank you very much I really appreciate your time to help me.
Use Levenshtein distance.
SELECT DISTINCT
data_customer.id_cust,
FIRST_VALUE(list_city.city) OVER ( PARTITION BY data_customer.id_cust
ORDER BY levenshtein(UPPER(list_city.city), UPPER(data_customer.city))) city
FROM list_city
CROSS JOIN data_customer;
Of course you must create user-defined function:
CREATE FUNCTION levenshtein( s1 VARCHAR(255), s2 VARCHAR(255) )

c = 0;
IF s1 = s2 THEN
RETURN 0;
ELSEIF s1_len = 0 THEN
RETURN s2_len;
ELSEIF s2_len = 0 THEN
RETURN s1_len;
ELSE
WHILE j <= s2_len DO
SET cv1 = CONCAT(cv1, UNHEX(HEX(j))),

END WHILE;
WHILE i <= s1_len DO
SET s1_char = SUBSTRING(s1, i, 1),
c = i,
cv0 = UNHEX(HEX(i)),
j = 1;
WHILE j <= s2_len DO
SET c = c + 1;
IF s1_char = SUBSTRING(s2, j, 1) THEN
SET cost = 0;
ELSE
SET cost = 1;
END IF;
SET c_temp = CONV(HEX(SUBSTRING(cv1, j, 1)), 16, 10) + cost;
IF c > c_temp THEN
SET c = c_temp;
END IF;
SET c_temp = CONV(HEX(SUBSTRING(cv1, j+1, 1)), 16, 10) + 1;

tagName1, tagName2, tagname3
when 'M'
tagName1, tagName2, tagname3
when 'Y'
tagName1, tagName2, tagname3
But it didn't worked....
Below is the code that I wrote, while I play it only once.
Any advice, please..
DECLARE tagList varchar(255) DEFAULT 'tagName1,tagName2,tagName3';
DECLARE tagTypeList varchar(150) DEFAULT 'H,D,M,Y';
WHILE tagTypeList != '' DO
WHILE tagList != '' DO
SET tagNameArray = SUBSTRING_INDEX(tagList, ',', 1);
SET tagTypeArray = SUBSTRING_INDEX(tagTypeList, ',', 1);
IF(tagTypeArray = 'H') THEN
SET aDate = (SELECT (DATE_ADD(nDateTime, INTERVAL -1 HOUR)));
SET ago_Y = (SELECT DATE_FORMAT(aDate,'%Y'));
SET ago_M = (SELECT DATE_FORMAT(aDate,'%m'));
SET ago_D = (SELECT DATE_FORMAT(aDate,'%d'));
SET ago_H = (SELECT DATE_FORMAT(aDate,'%H'));
SET ago_W = (SELECT DATE_FORMAT(aDate,'%w'));
ELSEIF(tagTypeArray = 'D') THEN
SET aDate = (SELECT (DATE_ADD(nDateTime, INTERVAL -1 DAY)));
SET ago_Y = (SELECT DATE_FORMAT(aDate,'%Y'));
SET ago_M = (SELECT DATE_FORMAT(aDate,'%m'));
SET ago_D = (SELECT DATE_FORMAT(aDate,'%d'));
SET ago_H = 0;
SET ago_W = 0;
ELSEIF(tagTypeArray = 'M') THEN
SET aDate = (SELECT (DATE_ADD(nDateTime, INTERVAL -1 MONTH)));
SET ago_Y = (SELECT DATE_FORMAT(aDate,'%Y'));
SET ago_M = (SELECT DATE_FORMAT(aDate,'%m'));
SET ago_D = 0;
SET ago_H = 0;
SET ago_W = 0;
ELSEIF(tagTypeArray = 'Y') THEN
SET aDate = (SELECT (DATE_ADD(nDateTime, INTERVAL -1 YEAR)));
SET ago_Y = (SELECT DATE_FORMAT(aDate,'%Y'));
SET ago_M = 0;
SET ago_D = 0;
SET ago_H = 0;
SET ago_W = 0;
END IF;
SET selectValue = (SELECT tagvalue FROM datasource WHERE tagname = tagNameArray and tagtype = tagTypeArray and y=ago_Y and m=ago_M and d=ago_D and h=ago_H);
IF(selectValue IS NULL OR selectValue = '')
THEN
SET old_Value_3M = (Select LastValue from BwAnalogTable where TagName = tagNameArray and LogDate >= ago_3M order by LogDate desc, LogTime desc limit 1);
# Here Insert Querty
END IF;
IF LOCATE(',', tagList) > 0 THEN
SET tagList = SUBSTRING(tagList, LOCATE(',', tagList) + 1);
ELSE
SET tagList = '';
END IF;
END WHILE;
IF LOCATE(',', tagTypeList) > 0 THEN
SET tagTypeList = SUBSTRING(tagTypeList, LOCATE(',', tagTypeList) + 1);
ELSE
SET tagTypeList = '';
END IF;
END WHILE;
I have modified the code as shown below.
DECLARE done INT DEFAULT FALSE;
DECLARE tagType2 VARCHAR(255) DEFAULT '';
DECLARE tagName2 VARCHAR(255) DEFAULT '';
DECLARE tagType_Cur CURSOR for select tagType from tbtagtype;
DECLARE tagName_Cur CURSOR for select tagName from tbtaglist;
OPEN tagType_Cur;
LOOP1: LOOP
FETCH tagType_Cur INTO tagType2;
IF done THEN
CLOSE tagType_Cur;
LEAVE LOOP1;
END IF;
########## here insert your core query ###############
OPEN tagName_Cur;
LOOP2: LOOP
FETCH tagName_Cur INTO tagName2;
IF done THEN
CLOSE tagName_Cur;
SET done = FALSE;
LEAVE LOOP2;
END IF;
########## here insert your core query ###############
END LOOP LOOP2;
END LOOP LOOP1;
I'm not an SQL Expert but I want to know the query that searches at the same time passes these rules
# they differ only by one symbol;
# user's input has one extra symbol;
# user's input has one missing symbol.
# Note that the comparison should be case-insensitive.
Something like:
SELECT `name` FROM `table` WHERE `name` = 'frd'
| name |
--------
ford <---- # user's input has one missing symbol.
crd <----- # they differ only by one symbol
fr <------ # user's input has one extra symbol;
FRD <----- # Note that the comparison should be case-insensitive.
You need an implementation of Levenshtein. Like this one: http://www.artfulsoftware.com/infotree/qrytip.php?id=552
DELIMITER //
CREATE FUNCTION levenshtein( s1 VARCHAR(255), s2 VARCHAR(255) )
RETURNS INT
DETERMINISTIC
BEGIN
DECLARE s1_len, s2_len, i, j, c, c_temp, cost INT;
DECLARE s1_char CHAR;
-- max strlen=255
DECLARE cv0, cv1 VARBINARY(256);
SET s1_len = CHAR_LENGTH(s1), s2_len = CHAR_LENGTH(s2), cv1 = 0x00, j = 1, i = 1, c = 0;
IF s1 = s2 THEN
RETURN 0;
ELSEIF s1_len = 0 THEN
RETURN s2_len;
ELSEIF s2_len = 0 THEN
RETURN s1_len;
ELSE
WHILE j <= s2_len DO
SET cv1 = CONCAT(cv1, UNHEX(HEX(j))), j = j + 1;
END WHILE;
WHILE i <= s1_len DO
SET s1_char = SUBSTRING(s1, i, 1), c = i, cv0 = UNHEX(HEX(i)), j = 1;
WHILE j <= s2_len DO
SET c = c + 1;
IF s1_char = SUBSTRING(s2, j, 1) THEN
SET cost = 0; ELSE SET cost = 1;
END IF;
SET c_temp = CONV(HEX(SUBSTRING(cv1, j, 1)), 16, 10) + cost;
IF c > c_temp THEN SET c = c_temp; END IF;
SET c_temp = CONV(HEX(SUBSTRING(cv1, j+1, 1)), 16, 10) + 1;
IF c > c_temp THEN
SET c = c_temp;
END IF;
SET cv0 = CONCAT(cv0, UNHEX(HEX(c))), j = j + 1;
END WHILE;
SET cv1 = cv0, i = i + 1;
END WHILE;
END IF;
RETURN c;
END; //
Then you can use it like this:
SELECT * FROM yourTable WHERE levenshtein(yourColumn, 'word') <= 1
DELIMITER IS NEEDED FOR IT TO WORK

Hi please help me to solve this problem thanks in advance
I defined these functions in database

ELSEIF s1_len = 0 THEN

My chat table has only two columns Varchar(250) "soru" and "cevap"
I get following error when I execute my query
