“查询处理器耗尽内部资源，无法为MERGE生成查询计划”，包含2,600条记录和一个关键字段

标签： sql sql-server sql-merge

所以我正在为现有数据库编写Visual Studio SQL数据库项目。

我正在为每个表生成简单的合并脚本，用于站立数据，现有数据等等。直到我来到一个特定的桌子，这给了我标题中的错误，这是相对直接的。

现在，如果这是一个我理解的复杂查询，但事实并非如此，它有一个带有聚簇索引的关键字段，没有复杂的操作。我已经尝试在第一个AND之后从MATCHED检查中删除所有ISNULL检查，它仍然给我相同的错误。我不明白！

它们的关键是[my_table_code]，第一列。为清晰起见，这是查询的大部分内容，只有第一行。

编辑：好的，这样就可以在几秒钟内删除2508行。我对合并脚本知之甚少，不知道为什么行数会影响这个。

1 个答案:

答案 0 :(得分：0)

首先将值插入临时表并在合并中引用它来修复它。

另外，将NULLIF的长列表替换为：

WHEN MATCHED AND EXISTS
(
SELECT Source.*
EXCEPT
SELECT Target.*
)

努力加快速度。
