QueryBuilder lastInsertId()

Question

我想要条目的最后一个UID。mysql为"insertId()“。这在Extbase中是如何工作的？

$queryBuilder = GeneralUtility::makeInstance(ConnectionPool::class)->getQueryBuilderForTable($table);
$queryBuilder
   ->insert($table)
   ->values([
       'test_id'          => 1,
       'test2_id'         => 2,
   ]);

$queryBuilder->execute();

$queryBuilder = GeneralUtility::makeInstance(ConnectionPool::class)->getQueryBuilderForTable($table2);
$queryBuilder
   ->insert($table2)
   ->values([
       'uid_local'         => ?, // uid from $table
       'uid_foreign'       => 1
   ]);
$queryBuilder->execute();

您可以使用$queryBuilder->getConnection()->lastInsertId();获取最后一个插入id

因此，这将使它：

$queryBuilder = GeneralUtility::makeInstance(ConnectionPool::class)->getQueryBuilderForTable($table);
$queryBuilder
   ->insert($table)
   ->values([
       'test_id'          => 1,
       'test2_id'         => 2,
   ]);

$queryBuilder->execute();
$tableUid = $queryBuilder->getConnection()->lastInsertId();

$queryBuilder = GeneralUtility::makeInstance(ConnectionPool::class)->getQueryBuilderForTable($table2);
$queryBuilder
   ->insert($table2)
   ->values([
       'uid_local'         => $tableUid,
       'uid_foreign'       => 1
   ]);
$queryBuilder->execute();

我有点不确定在使用QueryBuilder插入新记录时它是否可用，但是Docs中的迁移指南解释了如何在新的TYPO3数据库层中迁移sql_insert_id()方法

https://docs.typo3.org/typo3cms/CoreApiReference/ApiOverview/Database/Migration/Index.html#sql-insert-id

提示：

(int)$databaseConnectionForPages->lastInsertId('pages');
