如何测试以下查询是否成功执行?

How can I test to see if the following query executed successfully?

$STH = $this->_db->prepare("UPDATE UserCreds SET VerificationString=:newVerificationString, ExpiryDate=:expiryDate WHERE UserID = :userID;"); $STH->execute($params);

我知道添加新行时可以使用lastInsertId()，但是UPDATE和SELECT呢?

I know I can use lastInsertId() when I'm adding new rows, but what about UPDATEs and SELECTs?

推荐答案

execute成功返回true，失败返回false.

The execute returns true on success and false on failure.

来自文档:

成功返回TRUE，失败返回FALSE.

Returns TRUE on success or FALSE on failure.

因此，您可以确保查询成功运行，如:

So you can make sure query ran successfully like:

if ($STH->execute($params)) { // success } else { // failure }
