Question

如果查询有错误，我正在尝试输出错误消息，这是我的代码：

class app {

    private $db;
    private $con;
    private $err;
    ...

public function addNewRelative($parentId, $name, $relationCode, $relation, $phone, $email) {

    $sql = "BEGIN XXDM_DSQUARE_PKG.CREATE_CONTACTS(
                :P_SUBJECT_PARTY_ID,
                :P_OBJECT_PARTY_NAME',
                :P_RELATIONSHIP_CODE,
                :P_RELATIONSHIP_TYPE,
                :P_MOBILE_NUMBER,
                :P_EMAIL_ADDRESS,
                :X_ERROR_MSG
            ); END;";            

    //Statement does not change
    $stmt = oci_parse($this->con, $sql);

    oci_bind_by_name($stmt, ':P_SUBJECT_PARTY_ID', $parentId);
    oci_bind_by_name($stmt, ':P_OBJECT_PARTY_NAME', $name);
    oci_bind_by_name($stmt, ':P_RELATIONSHIP_CODE', $relationCode);
    oci_bind_by_name($stmt, ':P_RELATIONSHIP_TYPE', $relation);
    oci_bind_by_name($stmt, ':P_MOBILE_NUMBER', $phone);
    oci_bind_by_name($stmt, ':P_EMAIL_ADDRESS', $email);
    oci_bind_by_name($stmt, ':X_ERROR_MSG', $this->err);

    // Execute the statement as in your first try
    if (oci_execute($stmt)) {
        return json_encode(["response"=>1]);
    } else {
        return json_encode(["response"=>0]);
    }
}

但是出现以下错误：

Warning: oci_execute(): ORA-06550: line 8, column 6: PLS-00363: expression '&lt;null&gt;' cannot be used as an assignment target ORA-06550: line 1, column 7: PL/SQL: Statement ignored in D:\Server\wamp\www\dmg-dsquares-bk\app.php on line 94

问题出在“ X_ERROR_MSG”参数，因为它是OUT参数，我不知道如何绑定它。

处理绑定变量Oracle / PHP中的错误
