我尝试在 PDO SELECT 查询中使用 TRIM() 并收到一条语法错误消息“语法错误或访问冲突：1064 你的 SQL 语法有错误；”。我应该怎么做才能纠正这个错误？
D B：
tblrecord (firstname, lastname, score)
PHP：
$firstname = trim('Mary');
$lastname = trim('Lamb');
$sql = "SELECT * FROM tblrecord WHERE TRIM(firstname) AS firstname = ? AND TRIM(lastname) AS lastname = ?";
$stmt = $connection->prepare($sql);
$stmt->execute( array($firstname, $lastname) );
不要在上面使用别名 WHERE
$sql = "SELECT * FROM tblrecord WHERE TRIM(firstname) = ? AND TRIM(lastname) = ?";
