使用PHP更新mysql中的多行

Question

I have folliwing PHP file

which is creating this table:

Table createb by PHP with MySQL data

Every row have two inputs. My DB table has AUTO_INCREMENT 'ID' field.

How can I update my DB Table and make sure that rows will be updated accordingly to the ID's (auto incremented field)?

I'm must admit that SQL with PHP is very new to me and I don't know is this correct way of doing it?

            $news_SQLupdate = "UPDATE news SET ";   // table name is 'news'     
            $news_SQLupdate .=  "LIVE= '".$LIVE."', ";
            $news_SQLupdate .=  "CONTENT= '".$CONTENT."', ";
            $news_SQLupdate .=  "WHERE ID = '".$ID."' "; 

Answer 1

通过在WHERE子句中包含id？

UPDATE <someTable> SET ... WHERE id = <someId>

Answer 2

I tried this one state above:

UPDATE table_name 
SET column_name1=' value[$array]', 
    column_name2=' value[$array]' 
WHERE column_name=' value[$array]' ; 

Just confirming that it worked for me perfectly.

Answer 3

In your update statement, you will need a where id=(the id number)

Simple example:

UPDATE table_name set field1=value1 where id=1

Answer 4

UPDATE `tblContent` SET `On/Off` = true WHERE (`ID` = 1 OR `ID` = 2)

动态地在where子句中添加OR ID = X以将更改应用于另一个记录。

Answer 5

“UPDATE table_name SET column_name1 ='value [$ array]'，column_name2 ='value [$ array]'WHERE column_name ='value [$ array]'”;
