How to Store and Retrieve Hindi Language Data in MySQL Using Unicode?

Storing Unicode Data for Hindi Language in MySQL

When dealing with data that includes non-English characters, such as Hindi, it becomes crucial to store and retrieve it accurately in Unicode format to maintain its readability.

Choosing the Right Character Set and Collation

To ensure compatibility with Hindi characters, opt for the 'utf8' character set and 'utf8_general_ci' collation. This allows MySQL to store and manipulate Unicode data correctly.

Altering Table Field for Unicode Support

If you have a table with an existing field that needs to accommodate Hindi text, modify its definition using the following syntax:

ALTER TABLE `<table_name>` CHANGE `<field_name>` `<field_name>` VARCHAR(100) CHARSET utf8 COLLATE utf8_general_ci DEFAULT '' NOT NULL;

Setting Character Set for Connection

Before interacting with the database, establish the 'utf8' character set to ensure proper encoding:

mysql_set_charset('utf8');

Inserting and Retrieving Hindi Text

With the character set set, insert Hindi text into your database:

mysql_query("INSERT INTO ...."); // Replace with your query

Retrieve the inserted text by executing:

mysql_query("SELECT * FROM ...."); // Replace with your query

Handling Unicode Output

To display Hindi text correctly in a web browser, set the content type of the page using a meta tag:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

Example

The following code snippet demonstrates the storage and retrieval of Hindi text in the database:

// Set character set
mysql_set_charset('utf8');

// Insert Hindi text
mysql_query("INSERT INTO `hindi_text` (`text`) VALUES ('नवीन खेतिहर उपकरण')");

// Retrieve Hindi text
$result = mysql_query("SELECT `text` FROM `hindi_text`");
$hindiText = mysql_fetch_assoc($result)['text'];

// Output Hindi text with proper content type
echo '<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
' . $hindiText . '
';

By following these steps, you can ensure the accurate storage and readability of Hindi language data in MySQL.
