Question

我正在我的Doctrine迁移中执行手动准备的语句。我正在这样做，因为我需要最后插入的ID来构建进一步的相关查询。使用标准addSql方法不允许这样做，因为它的性质＆＃34;排队＆＃34;查询然后在最后执行它们。

有没有办法阻止显示以下错误消息？

Migration 20151102112832 was executed but did not result in any SQL statements.

执行了很多SQL语句，但是在调用我的这个方法时它们是执行的：

/**
 * @param string $sql
 *
 * @throws DBALException
 */
private function runSql($sql)
{
    $this->write($sql);
    $stmt = $this->connection->prepare($sql);
    $stmt->execute();
}

Answer 1

你可以创建一个＆＃34;什么都不做＆＃34; SQL：

public function up(Schema $schema)
{
    $this->addSql('SELECT 1');
}

Answer 3

我认为这里是显示您的迁移工作的最佳选择。您可以执行此操作，并通过发送带注释字符串的sql请求来抑制警告消息。例如：

public function up(Schema $schema)
{
    // Do not show warning on migrations.
    $this->addSql('# Updating entities.');
}

Answer 4

我使用时，Doctrine迁移版本3在MySQL5.7上引发了一个错误：

public function up(Schema $schema)
{
    $this->addSql('SELECT 1');
}

错误消息：

[error] Migration DoctrineMigrations\Version20190823142208 failed during Post-Checks. Error: "An exception occurred while executing 'SHOW FULL TABLES WHERE Table_type = 'BASE TABLE'':

SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active.  Consider using PDOStatement::fetchAll().  Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute."

使用注释可以解决此错误：

public function up(Schema $schema)
{
    $this->addSql('#prevent warning' ); //Prevent “Migration executed but did not result in any SQL statements”
}

阻止＆＃34;迁移已执行但未导致任何SQL语句＆＃34;在Doctrine迁移中运行自定义SQL时的消息
