如何使用非英语(孟加拉语)语言将数据输入到此数据库表中?

As pointed out by @Tim you need to change the collation of your table/database/column to UTF-8. First check the collation of your database/table/column.

检查整理:

如何检查DATABASE的排序:

SELECT
    default_character_set_name
FROM
    information_schema.SCHEMATA
WHERE
    schema_name = "YOUR_DATABASE_NAME";

如何检查TABLE的排序规则:

SELECT
    CCSA.character_set_name
FROM
    information_schema.`TABLES` T,
    information_schema.`COLLATION_CHARACTER_SET_APPLICABILITY` CCSA
WHERE
    CCSA.collation_name = T.table_collation
AND T.table_schema = "YOUR_DATABASE_NAME"
AND T.table_name = "YOUR_TABLE_NAME";

如何检查 COLUMN 的排序规则:

SELECT
    character_set_name
FROM
    information_schema.`COLUMNS`
WHERE
    table_schema = "YOUR_DATABASE_NAME"
AND table_name = "YOUR_TABLE_NAME"
AND column_name = "YOUR_COLUMN_NAME";

更改排序规则:

如何更改数据库排序规则:

ALTER DATABASE YOUR_DATABASE_NAME CHARACTER SET utf8 COLLATE utf8_unicode_ci;

如何更改表格排序规则:

ALTER TABLE YOUR_TABLE_NAME CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;

如何更改列排序规则:

ALTER TABLE YOUR_TABLE_NAME MODIFY YOUR_COLUMN_NAME VARCHAR(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci;

示例:

DROP TABLE IF EXISTS `sample_table`;
CREATE TABLE `sample_table` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) DEFAULT NULL,
  `language` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

INSERT INTO sample_table(name,language) VALUES('Ed Sheeran','English');
INSERT INTO sample_table(name,language) VALUES('আয়েশা খাতুন সুজানা','আমার সোনার বাংলা');

看，表定义中使用的CHARSET是utf8.因此，您可以在表中存储 unicode 字符.

| id |               name |         language |
|----|--------------------|------------------|
|  1 |         Ed Sheeran |          English |
|  2 |    আয়েশা খাতুন সুজানা |  আমার সোনার বাংলা |
