Faka idatha ye-MySQL

Ukusetshenziswa kwethebula le-MySQL FAKA FAKA Isitatimende se-SQL sokufaka idatha.

Ungafaka idatha kuthebula ledatha ngefasitela le-mysql> lomyalo, noma ngeskripthi se-PHP ukuze ufake idatha.

uhlelo lolimi

Okulandelayo kuvamile ekufakeni idatha kumathebula edatha ye-MySQL FAKA FAKA I-syntax ye-SQL:

INSERT INTO table_name ( field1, field2,...fieldN )
                       VALUES
                       ( value1, value2,...valueN );

Uma idatha iwuhlobo lohlamvu, kufanele usebenzise izingcaphuno ezizodwa noma izingcaphuno ezimbili, njengokuthi: "value".

Faka idatha ngewindi lomyalo womyalo

Ngezansi sizosebenzisa i-SQL FAKA FAKA Isitatimende sifaka idatha kuthebula ledatha le-MySQL elithi chenweiliang_tbl

Isibonelo

Esibonelweni esilandelayo sizofaka izingcezu ezintathu zedatha kuthebula le-chenweiliang_tbl:

root@host# mysql -u root -p password;
Enter password:*******
mysql> use chenweiliang;
Database changed
mysql> INSERT INTO chenweiliang_tbl 
    -> (chenweiliang_title, chenweiliang_author, submission_date)
    -> VALUES
    -> ("学习 PHP", "菜鸟教程", NOW());
Query OK, 1 rows affected, 1 warnings (0.01 sec)
mysql> INSERT INTO chenweiliang_tbl
    -> (chenweiliang_title, chenweiliang_author, submission_date)
    -> VALUES
    -> ("学习 MySQL", "菜鸟教程", NOW());
Query OK, 1 rows affected, 1 warnings (0.01 sec)
mysql> INSERT INTO chenweiliang_tbl
    -> (chenweiliang_title, chenweiliang_author, submission_date)
    -> VALUES
    -> ("JAVA 教程", "chenweiliang.com", '2016-05-06');
Query OK, 1 rows affected (0.00 sec)
mysql>

Qaphela: Maka ngemicibisholo -> Ayiyona ingxenye yesitatimende se-SQL, imane imele umugqa omusha. Uma isitatimende se-SQL siside kakhulu, singakha umugqa omusha ukuze sibhale isitatimende se-SQL ngokusebenzisa ukhiye othi Enter. Isinqamuli somyalo sesitatimende se-SQL isemikholoni ;,

Esibonelweni esingenhla, asizange sinikeze idatha ye-chenweiliang_id, ngoba le nkambu isethwe njengesibaluli esingu-AUTO_INCREMENT ngenkathi sidala ithebula.Ngakho-ke, inkambu izokwengezwa ngokuzenzakalelayo ngaphandle kokuthi sidinge ukuyisetha.Esibonelweni MANJE () kuwumsebenzi we-MySQL obuyisela usuku nesikhathi.

Okulandelayo, singabuka idatha yethebula ledatha nesitatimende esilandelayo:

Faka idatha usebenzisa umbhalo we-PHP

Ungasebenzisa umsebenzi we-PHP's mysqli_query() ukwenza I-SQL FAKA KUumyalo wokufaka idatha.

Umsebenzi unamapharamitha amabili futhi ubuyisela TRUE uma ukwenza kuphumelele, ngaphandle kwalokho ubuyisela FALSE.

uhlelo lolimi

mysqli_query(connection,query,resultmode);

Isibonelo

Uhlelo olusesibonelweni esilandelayo luthola izinkambu ezintathu zedatha efakwe umsebenzisi bese izifaka kuthebula ledatha:

<?
php
$dbhost = 'localhost:3306'; // mysql服务器主机地址
$dbuser = 'root'; // mysql用户名
$dbpass = '123456'; // mysql用户名密码
$conn = mysqli_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
 die('连接失败: ' . mysqli_error($conn));
}
echo '连接成功
';
// 设置编码，防止中文乱码
mysqli_query($conn , "set names utf8");
 
$chenweiliang_title = '学习 Python';
$chenweiliang_author = 'chenweiliang.com';
$submission_date = '2016-03-06';
 
$sql = "INSERT INTO chenweiliang_tbl ".
 "(chenweiliang_title,chenweiliang_author, submission_date) ".
 "VALUES ".
 "('$chenweiliang_title','$chenweiliang_author','$submission_date')";
 
 
 
mysqli_select_db( $conn, 'chenweiliang' );
$retval = mysqli_query( $conn, $sql );
if(! $retval )
{
 die('无法插入数据: ' . mysqli_error($conn));
}
echo "数据插入成功\n";
mysqli_close($conn);
?>

Okulandelayo, singabuka idatha yethebula ledatha nesitatimende esilandelayo:
