Kedu otu esi etinye data na tebụl nchekwa data MySQL ? Ihe atụ nke nkwupụta PHP maka itinye data na MySQL.

MySQL tinye data

Na MySQL, a na-eji nkwupụta INSERT INTO SQL etinye data n'ime tebụl.

Ị nwere ike itinye data na tebụl data site na mysql> windo ngwa ngwa, ma ọ bụ site na ederede PHP iji tinye data.

ụtọ asụsụ

Ihe ndị a bụ usoro nhazi INSERT INTO SQL maka itinye data na tebụl MySQL :

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

Ọ bụrụ na data ahụ bụ ụdị agwa, ị ga-ejirịrị otu nkwuputa ma ọ bụ nhụta okpukpu abụọ, dịka: "uru".

Tinye data site na windo ngwa ngwa

N'okpuru ebe a, anyị ga-eji nkwupụta SQL INSERT INTO tinye data n'ime tebụl MySQL chenweiliang_tbl.

ihe atụ

N'ihe atụ na-esonụ, anyị ga-etinye data atọ n'ime tebụl 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

Rịba ama: Akụ -> abụghị akụkụ nke nkwupụta SQL; ọ na-egosi naanị ahịrị ọhụrụ. Ọ bụrụ na nkwupụta SQL dị ogologo, anyị nwere ike ịmepụta ahịrị ọhụrụ site na ịpị Enter. Ihe njedebe iwu maka nkwupụta SQL bụ semicolon ;.

N'ihe atụ a dị n'elu, anyị enyeghị data nke chenweiliang_id, n'ihi na edobere mpaghara a ka àgwà AUTO_INCREMENT mgbe anyị mepụtara tebụl.Ya mere, ubi ga-akpaghị aka na-abawanye na-enweghị anyị mkpa ịtọ ya.Na ihe atụ UGBUA() bụ ọrụ MySQL na-eweghachi ụbọchị na oge.

Ọzọ, anyị nwere ike ịlele data tebụl data na nkwupụta ndị a:

Jiri script PHP tinye data

I nwere ike iji ọrụ mysqli_query() nke PHP mee iwu SQL INSERT INTO iji tinye data.

Ọrụ ahụ nwere parampat abụọ wee weghachi TRUE ma ọ bụrụ na ogbugbu ahụ gara nke ọma, ma ọ bụghị ya, ọ ga-alaghachi FALSE.

ụtọ asụsụ

mysqli_query(connection,query,resultmode);

ihe atụ

Ihe omume dị na ihe atụ a na-enweta mpaghara data atọ nke onye ọrụ tinyere wee tinye ha na tebụl data:
