MySQL inogadzira tafura yedata

Kugadzira tafura yedata yeMySQL inoda ruzivo runotevera:

• 表名
• tafura munda zita
• Tsanangura ndima yega yega yetafura

girama

Inotevera ndiyo yakajairika SQL syntax yekugadzira MySQL data matafura:

CREATE TABLE table_name (column_name column_type);

Mumuenzaniso unotevera tichagadzira iyo data tafura chenweiliang_tbl mune chenweiliang dhatabhesi:

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;

Muenzaniso ongororo:

• Kana iwe usingadi kuti minda ive null Unogona kuseta zvivakwa zvemunda HAPANA, paunenge uchishanda dhatabhesi, kana iyo data yakapinda mundima iyi irinull , kukanganisa kuchaziviswa.
• AUTO_INCREMENT inotsanangurwa seauto-incrementing hunhu, inowanzo shandiswa makiyi ekutanga, uye kukosha kunozowedzera ne1.
• PRIMARY KEY keyword inoshandiswa kutsanangura koramu sekiyi yekutanga. Unogona kushandisa makoramu akawanda kutsanangura kiyi yekutanga, yakaparadzaniswa nemakoma.
• ENGINE inoseta injini yekuchengetera uye CHARSET inoseta iyo encoding.

Gadzira tafura kuburikidza nekuraira nekukurumidza

MySQL data matafura anogona kugadzirwa nyore kuburikidza ne mysql> command window. Unogona kushandisa SQL statements Gadzira tafura kugadzira tafura yedata.

muenzaniso

Unotevera muenzaniso wekugadzira iyo data tafura 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>

Ongorora:The MySQL command terminator is a semicolon (;).

Gadzira tafura yedata uchishandisa PHP script

Unogona kushandisa PHP mysqli_query() Basa rekugadzira tafura yedata kubva kune iripo database.

Basa racho rine maparamendi maviri uye rinodzorera TRUE kana kuurayiwa kwabudirira, zvikasadaro inodzorera FALSE.

girama

mysqli_query(connection,query,resultmode);

muenzaniso

Muenzaniso unotevera unoshandisa PHP script kugadzira tafura yedata:
