Question

我有一个庞大的数据库，需要一个查询来更新数据库中的不同表。我相信这应该很容易，因为我正在改变的列在每个表中是相同的。这是我到目前为止所拥有的;

我不确定为什么这不会起作用，因为所有表都在更新他们的计划列。当这个运行时，我得到一个：ILLEGAL SYMBOL“令牌”。一些可能是法律的符号是：令牌列表。

查询中需要更改的内容才能使所有表都使用相同的数据进行更新。

Answer 1

您无法在单个更新语句中更新多个表。 [Update multiple tables in SQL Server using INNER JOIN

Answer 2

为什么要在一个语句中更新所有表？假设您使用的是最新版本的LUW，您实际上可以通过转换表和cte根据以下内容进行更新：

with t1 (n) as ( select count(1) 
                 from new table (
                     update a_assets 
                         set planer = ?
                     where planer = ?
                 )
               )
    , t2 (n) as ( ...

               )
    , ...

    , tn (n) as ( ...

               )
 select n from t1
 union all
 select n from t2
 ...
 select n from tn

但我怀疑这不是你想要的。

我建议您创建一个循环遍历表的过程，然后使用execute immediate来触发语句
