如何使用PDO / php从具有相同id的第二个表中提取数据？

Question

DESCRIPTION

I use the script below to displays all rows in my floradstable. I have a second table florinvtable that has identical columns. The Price column in floradstable = 0.00 whereas the Price column in florinvtable contains the real price.

$result = $pdo->prepare(
"SELECT floradstable.Brand, florinvtable.Price
FROM   floradstable INNER JOIN florinvtable
ON     floradstable.Barcode=florinvtable.Barcode
ORDER BY Brand");

$result->execute();

while ($row = $result->fetch(PDO::FETCH_ASSOC))
{
echo $row['Brand']." ";
echo $row['florinvtable.Price']." ";
echo "<a href='submit-ads-florida.php?deleteid=".$row['Barcode']."'>DELETE</a><br>";
}

OBJECTIVE

I would like to echo the price from florinvtable using the unique id(Barcode) both tables share.

PROBLEM

florinvtable.Price does not echo which leads me to believe it is echo(ing) from floradstable verses florinvtable.

NOTE

The current script works as is, without an error but does not pull Price FROM florinvtable

Answer 1

With the select you defined:

$result = $pdo->prepare(
"SELECT floradstable.Brand, florinvtable.Price
FROM   floradstable INNER JOIN florinvtable
ON     floradstable.Barcode=florinvtable.Barcode
ORDER BY Brand");

the columns in the result set are just called Brand and Price . The table reference is to fetch the correct one, not part of the name.

Try

echo $row['Price']." ";

Edit: I see you also use $row['Barcode'] , which would not be defined by that query! You would need

$result = $pdo->prepare(
"SELECT floradstable.Brand, florinvtable.Price, floradstable.Barcode
FROM   floradstable INNER JOIN florinvtable
ON     floradstable.Barcode=florinvtable.Barcode
ORDER BY Brand");
