Question

我有一个包含以下数据的表

<?php
interface ISanitizedValue {
    public function value();
}

class CSanitizedLogin implements ISanitizedValue {
    private $_rawValue;

    public function __construct($value){
        $this->_rawValue = $value;
    }

    public function value(){
        // sanitizing
    }
}

class CSomeClass {
    // force to use ISanitizedValue
    public function __construct(ISanitizedValue $login){}
}

$login = new CSanitizedLogin($_GET['login']);
$example1 = new CSomeClass($login);
$example2 = new CSomeClass($login);
?>

我希望将其转换为如下表所示

SKU     Site  Code    Value
0890    50    BRAND   OMH
0890    50    CSBC    0763440890
0890    50    DWPS    0763440890
0890    50    DWS     0763440890
0890    50    DWSG    *
0890    50    EA      1

我们拥有的Oracle数据库版本是10G，所以PIVOT还没用。

请帮忙。

Oracle 10没有数据透视表，因此您可以使用条件聚合：

select sku,
       max(case when code = 'BRAND' then value end) as brand,
       max(case when code = 'CSBC' then value end) as CSBC,
       max(case when code = 'DWPS' then value end) as DWPS,
       max(case when code = 'DWS' then value end) as DWS,
       max(case when code = 'DWSG' then value end) as DWSG,
       max(case when code = 'EA' then value end) as ea
from t
group by sku;

Oracle 10g中的PIVOT功能
