如何在执行多个查询时让PDO抛出异常?
如果我自己运行错误的sql:
$execute($ddl_partial);
$execute($insert);
然后我得到了预期的错误:
PHP致命错误:未捕获PDOException:SQLSTATE [42S22]:找不到列:207 [Microsoft] [SQL Server的ODBC驱动程序13] [SQL Server]无效的列名称“其他”。 (SQLExecute [207] at /build/php7.0-41GaEn/php7.0-7.0.8/ext/pdo_odbc/odbc_stmt.c:260)>
但是,如果我首先运行一些好的SQL并使用坏的跟进,那么它只是吞下错误并且一切正常。但之后查看数据库确认所有查询在错误语句后失败。
$execute($ddl_full);
$execute($insert);
$execute($drop);
$execute($ddl_partial);
$execute($insert);
我正在使用while ($statement->nextRowset())
重复所有返回的行集demonstrated in this answer,但它只打印了8次:
array(4) { [0] => string(5) "00000" [1] => int(0) [2] => string(24) " ((null)[0] at (null):0)" [3] => string(0) "" }
加起来:
为什么我没有从错误的声明中收到错误消息?
<?php
$hostname = 'microsoftsql.example.com';
$database = 'mydb';
$username = 'user';
$password = 'P@55w0rd';
// https://www.microsoft.com/en-us/download/details.aspx?id=50419
$driver = 'ODBC Driver 13 for SQL Server';
$pdo = new PDO("odbc:Driver=$driver;
Server=$hostname;
Database=$database",
$username,
$password
);
$pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
$pdo->setAttribute( PDO::ATTR_EMULATE_PREPARES, false );
$drop = "DROP TABLE testerino;";
$ddl_full = "
CREATE TABLE testerino (
value VARCHAR(10),
other VARCHAR(10)
);
";
$ddl_partial = "
CREATE TABLE testerino (
value VARCHAR(10)
);
";
$insert = "
INSERT INTO testerino (value)
VALUES ('first');
INSERT INTO testerino (value, other)
VALUES ('second', 'another');
INSERT INTO testerino (value)
VALUES ('third');
";
$execute = function (String $sql) use ($pdo) {
$pdo->beginTransaction();
try {
$statement = $pdo->prepare($sql);
$statement->execute();
do {
/* https://bugs.php.net/bug.php?id=61613 */
var_dump($statement->errorInfo());
} while ($statement->nextRowset());
$pdo->commit();
} catch (PDOException $e) {
$pdo->rollBack();
throw $e;
} finally {
$statement->closeCursor();
}
};
$execute($drop); // not needed first time
$execute($ddl_full);
$execute($insert);
$execute($drop);
$execute($ddl_partial);
$execute($insert);
这对我来说是个大问题,因为永远不会抛出异常,因此事务不会回滚,最终只会插入1/3记录。我需要全部或全部。
