MySQL faʻapipiʻi faʻamatalaga

MySQL laulau fa'aoga IA FAI totonu SQL faʻamatalaga e faʻapipiʻi ai faʻamatalaga.

E mafai ona e fa'aofi fa'amaumauga i totonu o le laulau fa'amaumauga e ala ile mysql> fa'amalama fa'atonu, po'o le PHP script e fa'aofi ai fa'amatalaga.

O mea nei e masani mo le faʻaofiina o faʻamatalaga i totonu o laulau faʻamaumauga MySQL IA FAI totonu SQL syntax:

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

Afai o faʻamaumauga o le ituaiga tagata, e tatau ona e faʻaogaina upusii tasi poʻo upusii faalua, pei o le: "taua".

Fa'aofi fa'amatalaga e ala ile fa'amalama fa'atonu

Lalo o le a matou faʻaaogaina SQL IA FAI totonu O le faʻamatalaga faʻapipiʻi faʻamatalaga i le MySQL data table chenweiliang_tbl

Fa'ata'ita'iga

I le faʻataʻitaʻiga o loʻo mulimuli mai o le a matou faʻaofiina ni fasipepa se tolu i le laulau 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());

Manatua: Faailoga i aū -> E le o se vaega o le faʻamatalaga SQL, e naʻo le sui o se laina fou. Afai o se faʻamatalaga SQL e umi tele, e mafai ona tatou fatuina se laina fou e tusi ai le faʻamatalaga SQL e ala i le faʻaogaina o le Enter key. semikona ;.

I le faʻataʻitaʻiga o loʻo i luga, matou te leʻi tuʻuina atu faʻamatalaga o chenweiliang_id, ona o lenei fanua ua setiina o le AUTO_INCREMENT uiga ina ua matou fatuina le laulau.O le mea lea, o le fanua o le a otometi lava ona faʻaopoopo e aunoa ma le manaʻomia ona matou setiina.I le faʻataʻitaʻiga NOW () o se MySQL galuega e toe faʻafoʻi ai se aso ma le taimi.

Ma le isi, e mafai ona tatou vaʻai i faʻamatalaga laulau faʻamaumauga ma le faʻamatalaga lea:

Fa'aofi fa'amaumauga e fa'aaoga ai le PHP script

E mafai ona e fa'aogaina le PHP mysqli_query() galuega e fai SQL FA'aofi I totonufa'atonuga e fa'aofi fa'amaumauga.

O le galuega e lua taʻiala ma toe faʻafoʻi le TRUE pe a manuia le faʻatinoga, a leai e toe foʻi mai le FALSE.

O le polokalame i le faʻataʻitaʻiga o loʻo i lalo e mauaina ni vaega se tolu o faʻamatalaga na tuʻuina atu e le tagata faʻaoga ma faʻaofi i totonu o le laulau faʻamaumauga:
