使用临时表的存储过程表现不佳

时间：2013-07-09 15:30:45

标签： sql sql-server performance stored-procedures temp-tables

我正在使用基于MS SQL Server的ERP系统。 它有一个货件提交过程，使用99个临时表来执行其工作。这项工作需要是原子的 - 所有这一切都需要发生，或者不应该发生。 此特定存储过程会影响数据库中的最大表。编写过程的方式不能很好地扩展。在我下午所有承诺大量发货的大客户中，SQL Server严重放缓。当没有负载时，该过程需要<1秒。当许多用户（15-30）正在发货时，该过程需要＆gt; 1分钟。

我有兴趣重新编写流程，使其在负载下更具性能。

所有临时表都有索引和/或聚簇索引。

我一直致力于使用过程中使用的永久表的索引进行性能调优。

我正在寻找一种更好的架构，使整个过程保持原子性，但使其更好地扩展。看来有些临时表只能保存少量记录（<100），而有些记录表会保留更多记录（> 10,000但<100,000）（我还没有完成确定的工作）这在经验上这一点）。我看到的替代方案如下：

  • 将一些临时表移动到表变量中以将数据保存在内存中
  • 将部分进程移出到从SQL调用的基于CLR的过程（可能某些逻辑在过程代码中比在t-sql中执行得更快）

请告诉我更多有助于推动此问题的具体信息。

附加信息（John Puttman - 2013年7月9日）

我跟踪执行以查看在此proc的运行中启动和提交的user_transactions - 在处理SP时启动并提交了多个事务 - 大多数事务嵌套在调用堆栈的SP中。调用堆栈最多嵌套9个级别（包括触发器时）。大约有27个不同的事务已启动并已提交。事务不是嵌套的。在执行存储过程时，系统使用逻辑锁定表来防止其他用户（进程）编辑与“出货”记录相关的记录。

以下是存储的主存储过程的片段，以了解代码的味道（注意一些错误记录代码已被删除）：

答案 0 :(得分：1)

当你需要“原子”时，你需要TRANS（BEGIN TRAN，COMMIT TRAN）。

在BEGIN TRAN语句之前，将所有“Shredding”或“Parsing”放入#temp表中。

Aka，在你调用BEGIN TRAN之前，应该设置所有的多米诺骨牌。 Aka，BEGIN TRAN / COMMIT TRAN中的所有内容都应尽可能精益。

查看Tran中Insert / Update /（Merge / Upsert）/ Delete Statements的顺序。 确保它们有意义....特别注意一些可能导致阻塞问题（死锁问题）与另一个通常称为存储过程的问题。
