[英]PHP MySQL INSERT data from another table using the where clause and insert unique values to the same rows
I want to insert data from one table into another where one field equals another in both tables. 我想将一个表中的数据插入到另一个表中,其中一个字段等于两个表中的另一个字段。 So far this works. 到目前为止这个工作。 The problem is, I also need to insert additional data into those same rows that is not included on the first table. 问题是,我还需要将其他数据插入到第一个表中未包含的相同行中。
//enter rows into database
foreach($_POST['sku'] as $row=>$sku)
{
//this is the data that needs to be added to the table
$item_sku=$sku;
$image="/$item_sku.jpg";
$small_image="/$item_sku.jpg";
$thumbnail="/$item_sku.jpg";
//currently this is what is working to import data from one table to the other
$sql= "INSERT INTO magento_import (sku, description, price)
SELECT PR_SKU, PR_Description, PR_UnitPrice
FROM products
WHERE PR_SKU = '$sku'";
//I need something here to add the above variables to the same row where PR_SKU = '$sku'
if (!mysql_query($sql))
{
die('Error: '.mysql_error());
}
echo "$row record added";
}
The columns for the missing data on magento_table are called 'image', 'small_image', and 'thumbnail'. magento_table上缺少数据的列称为“image”,“small_image”和“thumbnail”。 This is simple a hack to put data from an old product table into a new product table, export as a CSV, and run a profile in Magento. 将旧产品表中的数据放入新产品表,导出为CSV并在Magento中运行配置文件,这很简单。 I don't need to worry about SQL injections. 我不需要担心SQL注入。 It's something I'm running off of a local machine. 这是我在本地机器上运行的东西。 I'm trying to avoid as much manual data entry as possible while switching products over to a new ecommerce system. 在将产品切换到新的电子商务系统时,我试图避免尽可能多的手动数据输入。 Thanks for any help you can give. 谢谢你提供的所有帮助。
Selecting literal values should do what you intend: 选择文字值应该按照您的意图执行:
$sql= "INSERT INTO magento_import (sku, description, price, image, small_image, thumbnail)
SELECT PR_SKU, PR_Description, PR_UnitPrice, \"$image\", \"$small_image\", \"$thumbnail\"
FROM products
WHERE PR_SKU = '$sku'";
You can use another update statement to do this. 您可以使用另一个更新语句来执行此操作。 I doubt if you can do this with one single query 我怀疑你是否可以用一个查询来做到这一点
foreach($_POST['sku'] as $row=>$sku)
{
//this is the data that needs to be added to the table
$item_sku=$sku;
$image="/$item_sku.jpg";
$small_image="/$item_sku.jpg";
$thumbnail="/$item_sku.jpg";
//currently this is what is working to import data from one table to the other
$sql= "INSERT INTO magento_import (sku, description, price)
SELECT PR_SKU, PR_Description, PR_UnitPrice
FROM products
WHERE PR_SKU = '$sku'";
//I need something here to add the above variables to the same row where PR_SKU = '$sku'
if (!mysql_query($sql))
{
die('Error: '.mysql_error());
}else {
$sql = "UPDATE magento_import SET item='$item',image='$image',small_image='$small_image',thumbnail='$thumbnail' WHERE PR_SKU = '$sku'";
echo "$row record added";
}
}
You can just add the variables directly to the query. 您只需将变量直接添加到查询中即可。 As long as they are quoted they will work as simple values. 只要他们被引用,他们就会像简单的价值观一样工作。
$sql= "INSERT INTO magento_import (sku, description, price, x, y, z)
SELECT PR_SKU, PR_Description, PR_UnitPrice, '$x' AS x, '$y' AS y, '$z' AS z
FROM products
WHERE PR_SKU = '$sku'";
