SQLSERVER errorlog讲解

很多时候诊断SQLSERVER问题都需要看SQLSERVER的错误日志

日志里面很多内容没有书本专门讲解，今天我就讲一下，可能里面的日志信息是从我个人的机器

里抓出来的，跟大家的机器环境会有所不同，但是SQLSERVER启动部分的日志大家都是一样的

特别的说一下：2013-02-12 17:53:29.29 spid29s

这些spid指的是SQLSERVER内部的进程，因为SQLSERVER内部有SQL OS，所以称呼他自己内部的线程为“进程”

所以在Windows的任务管理器里是看不到这些“进程ID的”的，这些进程ID也会跟会话关联的，例如你在

SSMS里新建一个查询，SQLSERVER就会新建一个会话ID（SPID），这些“进程”可以kill的

<span>1</span> <span>KILL</span> spid <span>--</span><span>相应的spid</span>

相当于在cmd下运行：TASKKILL notepad.exe（进程ID）

不过这些kill命令是发给SQLSERVER去执行

在启动的时候，SQLSERVER会创建很多线程来进行初始化数据库或者其他工作，所以会看到下面的，但是spid会不同

2013-02-12 17:53:29.29 spid29s

<span>12</span> <span>--</span><span>包括命名管道，共享内存，TCP/IP</span>
<span>13</span> <span>--</span><span>因为开启了SQL BROSWER服务，所以会侦听1434端口</span>
<span>14</span> <span>--</span><span>SQL BROSWER的作用可以看MSDN</span>
<span>15</span> <span>--</span><span>专用管理员连接支持已经建立，也是侦听1434端口</span>
<span>16</span> <span>--</span><span>专用管理员连接DAC是当遇到数据库连接不上或者某些原因</span>
<span>17</span> <span>--</span><span>登录不了数据库而使用的，侦听1434的原因估计是因为</span>

<span>5</span> <span>--</span><span>所以手动打开了1222和1204跟踪标志</span>

就这麽多了，SQL ErrorLog不会很多，所以有时候遇到SQL问题先查找SQL ErrorLog里的记录会比较好

当然了，在SSMS里也能看到SQL ErrorLog，SSMS里还包括筛选和搜索功能，但是有时候如果连SQLSERVER服务都启动不了

那只能到SQL ErrorLog的目录里面，用记事本或者其他编辑器打开找问题原因了

MySQLのライセンスは、他のデータベースシステムと比較してどうですか？Apr 25, 2025 am 12:26 AM

MySQLはGPLライセンスを使用します。 1）GPLライセンスにより、MySQLの無料使用、変更、分布が可能になりますが、変更された分布はGPLに準拠する必要があります。 2）商業ライセンスは、公的な変更を回避でき、機密性を必要とする商用アプリケーションに適しています。

MyisamよりもInnodbを選びますか？Apr 25, 2025 am 12:22 AM

Myisamの代わりにInnoDBを選択する場合の状況には、次のものが含まれます。1）トランザクションサポート、2）高い並行性環境、3）高いデータの一貫性。逆に、Myisamを選択する際の状況には、1）主に操作を読む、2）トランザクションサポートは必要ありません。 INNODBは、eコマースプラットフォームなどの高いデータの一貫性とトランザクション処理を必要とするアプリケーションに適していますが、Myisamはブログシステムなどの読み取り集約型およびトランザクションのないアプリケーションに適しています。

MySQLの外国キーの目的を説明してください。Apr 25, 2025 am 12:17 AM

MySQLでは、外部キーの機能は、テーブル間の関係を確立し、データの一貫性と整合性を確保することです。外部キーは、参照整合性チェックとカスケード操作を通じてデータの有効性を維持します。パフォーマンスの最適化に注意し、それらを使用するときに一般的なエラーを避けてください。

MySQLのインデックスのさまざまなタイプは何ですか？Apr 25, 2025 am 12:12 AM

MySQLには、B-Treeインデックス、ハッシュインデックス、フルテキストインデックス、空間インデックスの4つのメインインデックスタイプがあります。 1.B-Treeインデックスは、範囲クエリ、ソート、グループ化に適しており、従業員テーブルの名前列の作成に適しています。 2。HASHインデックスは、同等のクエリに適しており、メモリストレージエンジンのHASH_TABLEテーブルのID列の作成に適しています。 3。フルテキストインデックスは、記事テーブルのコンテンツ列の作成に適したテキスト検索に使用されます。 4.空間インデックスは、地理空間クエリに使用され、場所テーブルのGEOM列での作成に適しています。

MySQLでインデックスをどのように作成しますか？Apr 25, 2025 am 12:06 AM

tocreateanindexinmysql、usethecreateindexstatement.1）forasinglecolumn、 "createdexidx_lastnameonemployees（lastname）;" 2）foracompositeindexを使用して、 "createindexidx_nameonemployees（lastname、firstname）;" 3）; "3）、" 3）を使用します

MySQLはSQLiteとどのように違いますか？Apr 24, 2025 am 12:12 AM

MySQLとSQLiteの主な違いは、設計コンセプトと使用法のシナリオです。1。MySQLは、大規模なアプリケーションとエンタープライズレベルのソリューションに適しており、高性能と高い並行性をサポートしています。 2。SQLiteは、モバイルアプリケーションとデスクトップソフトウェアに適しており、軽量で埋め込みやすいです。

MySQLのインデックスとは何ですか？また、パフォーマンスをどのように改善しますか？Apr 24, 2025 am 12:09 AM

MySQLのインデックスは、データの取得をスピードアップするために使用されるデータベーステーブル内の1つ以上の列の順序付けられた構造です。 1）インデックスは、スキャンされたデータの量を減らすことにより、クエリ速度を改善します。 2）B-Tree Indexは、バランスの取れたツリー構造を使用します。これは、範囲クエリとソートに適しています。 3）CreateIndexステートメントを使用して、createIndexidx_customer_idonorders（customer_id）などのインデックスを作成します。 4）Composite Indexesは、createIndexIDX_CUSTOMER_ORDERONORDERS（Customer_Id、Order_date）などのマルチコラムクエリを最適化できます。 5）説明を使用してクエリ計画を分析し、回避します

データの一貫性を確保するために、MySQLでトランザクションを使用する方法を説明します。Apr 24, 2025 am 12:09 AM

MySQLでトランザクションを使用すると、データの一貫性が保証されます。 1）StartTransactionを介してトランザクションを開始し、SQL操作を実行して、コミットまたはロールバックで送信します。 2）SavePointを使用してSave Pointを設定して、部分的なロールバックを許可します。 3）パフォーマンスの最適化の提案には、トランザクション時間の短縮、大規模なクエリの回避、分離レベルの使用が合理的に含まれます。
