带有 MySQL 插入 PDO 请求的错误 HY093

Question

After reading all others questions about the HY093, I open this one to figure out why I've got this message too.

Here is my table :

And here is my request : (Where $conn is my PDO connection)

$sql = $conn->prepare("INSERT INTO Sites (Email,URL,Title,Description,PageRank,Rewrite,MetaDesc,Origin,BackLink,nbBackLink,RssTitle,RssAddress,SocAddress,SocPostalCode,SocCity,SocCountry,SocTel,Offer,Status,nbHit)
                         VALUES (:Email,:URL,:Title,:Description,:PageRank,:Rewrite,:MetaDesc,:Origin,:BackLink,0,:RssTitle,:RssAddress,:SocAddress,:SocPostalCode,:SocCity,:SocCountry,:SocTel,:Offer,:Status,0)");
$sql->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );

$pageRank = new GooglePageRank($_POST["site_url"]);

$sql->bindParam(":Email",$_POST["submail"],PDO::PARAM_STR);
$sql->bindParam(":URL",$_POST["site_url"],PDO::PARAM_STR);
$sql->bindParam(":Title",$_POST["site_title"],PDO::PARAM_STR);
$sql->bindParam(":Description",$_POST["site_desc"],PDO::PARAM_STR);
$sql->bindParam(":PageRank",$pageRank->PageRank,PDO::PARAM_INT);
$sql->bindParam(":Rewrite",stringToRewrite($_POST["site_title"]),PDO::PARAM_STR);
$sql->bindParam(":MetaDesc",$_POST["site_desc"],PDO::PARAM_STR);
$sql->bindParam(":Origin",$_POST["site_country"],PDO::PARAM_STR);
$sql->bindParam(":BackLink",$_POST["site_backlink"],PDO::PARAM_STR);
$sql->bindParam(":RssTitle",$_POST["site_rss_title"],PDO::PARAM_STR);
$sql->bindParam(":RssAddress",$_POST["site_rss_addr"],PDO::PARAM_STR);
$sql->bindParam(":SocAddress",$_POST["soc_addr"],PDO::PARAM_STR);
$sql->bindParam(":SocPostalCode",$_POST["soc_cp"],PDO::PARAM_STR);
$sql->bindParam(":SocCity",$_POST["soc_city"],PDO::PARAM_STR);
$sql->bindParam(":SocCoutry",$_POST["soc_pays"],PDO::PARAM_STR);
$sql->bindParam(":SocTel",$_POST["soc_tel"],PDO::PARAM_STR);

$offer = $_POST["offer"] == "premium" ? 1 : 0;
$status = $_POST["offer"] == "premium" ? 2 : 0;

$sql->bindParam(":Offer",$offer,PDO::PARAM_INT);
$sql->bindParam(":Status",$status,PDO::PARAM_INT);

$sql->execute();
var_dump($sql->errorInfo());
var_dump($sql->errorCode());

Any idea why I keep have an HY093 error?

Answer 1

You have a typo in one of your bindParams, which means you have a mismatch in parameters:

$sql->bindParam(":SocCoutry",$_POST["soc_pays"],PDO::PARAM_STR);

should be

$sql->bindParam(":SocCountry",$_POST["soc_pays"],PDO::PARAM_STR);

Answer 2

Here's an interesting case I found:

Running this query:

INSERT INTO videosubmissions (member_login, submission_date) VALUES (":login", ":submission-date")

Bound with:

[ ':login',           $info['login'],   PDO::PARAM_STR ],
[ ':submission-date', $submission_date, PDO::PARAM_STR ]

works... but

INSERT INTO videosubmissions (member_login, submission_date) VALUES (:login, :submission-date)

fails with an HY093 error. I suspected this was caused by the implicit conversion from string to date but trying an explicit STR_TO_DATE(format, sDate) didn't fix it. However if I quote all my placeholders in other queries with PDO::PARAM_STR value, it caused problems.

I know this doesn't really answer the Q but it adds another case to the mix to help figure out what's up.

Answer 3

My issue was number of parameters didn't match number of placeholders. Might be worth adding this to @aynber's answer
