According to: https://adodb.org/dokuwiki/doku.php?id=v5:userguide:portable_sql#prepare_execute
$stmt = $db->prepare("SELECT * FROM customers WHERE custid=? AND state=?");
$rs = $db->execute($stmt, array(999,'New York'));
How does one preview the SQL that ADOdb prepares without Executing, first? Namely:
"SELECT * FROM customers WHERE custid=999 AND state='New York'"
This class provides a solution:
https://github.com/jasny/dbquery-mysql/blob/master/src/Jasny/DB/MySQL/QuerySplitter.php
$stmt = "SELECT * FROM customers WHERE custid=? AND state=?";
$params = array(999,'New York');
$split = new QuerySplitter;
$query = $split->bind($stmt , $params);
die($query);
//SELECT * FROM customers WHERE custid=99 AND state='New York'
