DELIMITER ;

但是错误：您的SQL语法有错误；查看与您的MariaDB服务器版本相对应的手册，以在'DECLARE v_RT LONGTEXT附近使用正确的语法；

最后一次：我要使用： fNonUnicode（“ Xinchàocácbạn”） return Xin chao cac ban

MySQL删除重音符号和特殊字符的功能

 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;

请尝试以下代码

DROP FUNCTION IF EXISTS fn_remove_accents;
DELIMITER //
CREATE FUNCTION fn_remove_accents(textvalue TEXT)
    RETURNS TEXT

BEGIN
    SET @textvalue = textvalue;

    -- ACCENTS
    SET @withaccents = 'ăâđêôơưàảãạáằẳẵặắầẩẫậấèẻẽẹéềểễệếìỉĩịíòỏõọóồổỗộốờởỡợớùủũụúừửữựứỳỷỹỵýĂÂĐÊÔƠƯÀẢÃẠÁẰẲẴẶẮẦẨẪẬẤÈẺẼẸÉỀỂỄỆẾÌỈĨỊÍÒỎÕỌÓỒỔỖỘỐỜỞỠỢỚÙỦŨỤÚỪỬỮỰỨỲỶỸỴÝ';
    SET @withoutaccents = 'aadeoouaaaaaaaaaaaaaaaeeeeeeeeeeiiiiiooooooooooooooouuuuuuuuuuyyyyyAADEOOUAAAAAAAAAAAAAAAEEEEEEEEEEIIIIIOOOOOOOOOOOOOOOUUUUUUUUUUYYYYY';
    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;

    RETURN @textvalue;
END
//
