I have the following query:
SELECT * FROM main_creditperson WHERE name="Irene Olga López"
This will reutrn:
id name
366354 Irene Olga López
Is there a simple way to do this in the query so the result is removed of all accents?
id name
366354 Irene Olga Lopez
You can try to create a function to replace accents to a normal word.
Schema (MySQL v5.6)
CREATE TABLE main_creditperson(id int,name Nvarchar(50));
INSERT INTO main_creditperson VALUES (366354,N'Irene Olga López');
ALTER TABLE main_creditperson
MODIFY name VARCHAR(50) CHARACTER SET utf8mb4
COLLATE utf8mb4_bin;
DROP FUNCTION IF EXISTS fn_remove_accents;
DELIMITER |
CREATE FUNCTION fn_remove_accents( textvalue VARCHAR(10000) ) RETURNS VARCHAR(10000)
BEGIN
SET @textvalue = textvalue;
-- ACCENTS
SET @withaccents = 'ŠšŽžÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÑÒÓÔÕÖØÙÚÛÜÝŸÞàáâãäåæçèéêëìíîïñòóôõöøùúûüýÿþƒ';
SET @withoutaccents = 'SsZzAAAAAAACEEEEIIIINOOOOOOUUUUYYBaaaaaaaceeeeiiiinoooooouuuuyybf';
SET @count = LENGTH(@withaccents);
WHILE @count > 0 DO
SET @textvalue = REPLACE(@textvalue, SUBSTRING(@withaccents, @count, 1), SUBSTRING(@withoutaccents, @count, 1));
SET @count = @count - 1;
END WHILE;
SET @special = '!@#$%¨&*()_+=§¹²³£¢¬"`´{[^~}]<,>.:;?/°ºª+*|\\''';
SET @count = LENGTH(@special);
WHILE @count > 0 do
SET @textvalue = REPLACE(@textvalue, SUBSTRING(@special, @count, 1), '');
SET @count = @count - 1;
END WHILE;
RETURN @textvalue;
END

If the COLLATION is any of the ..._ci variants, then accents are ignored when comparing. That is, no accent-stripping code is needed.
