MySQL pangani tebulo la data

Kupanga tebulo la data la MySQL kumafunikira izi:

• Dzina latebulo
• dzina lamunda wa tebulo
• fotokozani gawo lililonse la tebulo

galamala

Zotsatirazi ndizomwe zili mu SQL syntax popanga matebulo a data a MySQL:

CREATE TABLE table_name (column_name column_type);

Muchitsanzo chotsatirachi tipanga tebulo la data chenweiliang_tbl mu nkhokwe ya chenweiliang:

CREATE TABLE IF NOT EXISTS `chenweiliang_tbl`(
   `chenweiliang_id` INT UNSIGNED AUTO_INCREMENT,
   `chenweiliang_title` VARCHAR(100) NOT NULL,
   `chenweiliang_author` VARCHAR(40) NOT NULL,
   `submission_date` DATE,
   PRIMARY KEY ( `chenweiliang_id` )
)ENGINE=InnoDB DEFAULT CHARSET=utf8;

Kusanthula kwachitsanzo:

• Ngati simukufuna kuti munda ukhale NULL Zomwe zili m'munda zitha kukhazikitsidwa ngati OSAKHALA, pogwiritsira ntchito nkhokwe, ngati deta yomwe yalowetsedwa m'munda uno ndiNULL , cholakwika chidzanenedwa.
• AUTO_INCREMENT imatanthauzidwa ngati chiwonjezero chodziwonjezera chokha, chomwe chimagwiritsidwa ntchito ngati kiyi yoyamba, ndipo mtengo wake umangowonjezereka ndi 1.
• Mawu ofunikira a PRIMARY KEY amagwiritsidwa ntchito kutanthauzira gawo ngati kiyi yoyamba.Mutha kugwiritsa ntchito magawo angapo kutanthauzira makiyi oyamba, olekanitsidwa ndi koma.
• ENGINE imayika injini yosungira, ndipo CHARSET imayika encoding.

Pangani tebulo kuchokera ku Command Prompt

Matebulo a data a MySQL amatha kupangidwa mosavuta kudzera pawindo la mysql>.Mutha kugwiritsa ntchito mawu a SQL Pangani MITU kupanga tebulo la data.

Chitsanzo

Chotsatira ndi chitsanzo chopanga tebulo la data chenweiliang_tbl:

root@host# mysql -u root -p
Enter password:*******
mysql> use chenweiliang;
Database changed
mysql> CREATE TABLE chenweiliang_tbl(
   -> chenweiliang_id INT NOT NULL AUTO_INCREMENT,
   -> chenweiliang_title VARCHAR(100) NOT NULL,
   -> chenweiliang_author VARCHAR(40) NOT NULL,
   -> submission_date DATE,
   -> PRIMARY KEY ( chenweiliang_id )
   -> )ENGINE=InnoDB DEFAULT CHARSET=utf8;
Query OK, 0 rows affected (0.16 sec)
mysql>

Chidziwitso:MySQL command terminator ndi semicolon (;).

Pangani tebulo la data pogwiritsa ntchito PHP script

Mutha kugwiritsa ntchito ma PHP mysqli_query() ntchito kupanga tebulo la data kuchokera ku database yomwe ilipo.

Ntchitoyi ili ndi magawo awiri ndipo imabweretsanso TRUE ngati ntchitoyo ikuyenda bwino, apo ayi imabwezeretsa FALSE.

galamala

mysqli_query(connection,query,resultmode);

Chitsanzo

Chitsanzo chotsatirachi chimagwiritsa ntchito PHP script kupanga tebulo la deta:

<?
 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<br />';
 $sql = "CREATE TABLE chenweiliang_tbl( ".
 "chenweiliang_id INT NOT NULL AUTO_INCREMENT, ".

 "PRIMARY KEY ( chenweiliang_id ))ENGINE=InnoDB DEFAULT CHARSET=utf8; ";
 mysqli_select_db( $conn, 'chenweiliang' );
 $retval = mysqli_query( $conn, $sql );
 if(! $retval )
 {
