Question

我正在尝试连接并从PostgreSQL服务器中选择数据。我能够连接到服务器，但我的选择查询似乎运行错误。有什么建议吗？

<?php

$conn = "host=#### port=5432 dbname=consolidated user=#### password=####";

if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 
echo "Connected successfully";

$dbconn = pg_connect($conn);

$result = pg_query($dbconn, "SELECT id FROM retailer_retailer;");
if (!$result) {
  echo "An error occurred.\n";
  exit;
}

while ($row = pg_fetch_row($result)) {
  echo "ID: $row[0]";
  echo "<br />\n";
}

?>

你错过了这里的模式名称，我假设你在公共模式中有表，你的查询应该是 -

$result = pg_query($dbconn, "SELECT id FROM public.retailer_retailer;");

如果您有其他架构，则可以将public替换为其他架构名称
