错误 ORA-00907：调用 command.ExecuteReader() 时缺少右括号

Question

调用方法时，会发生错误。开括号和闭括号的数量相同。我无法理解错误是什么。

多么丑陋的代码！难怪你不能发现错误。

我删除了双引号和+ 符号。格式化程序然后显示：

<snip>
                       || DECODE (hs.ora3,
                                  NULL, NULL,
                                  ', ' || udmurtneft_n.dg_sdes (hs.ora3))
--> error          FROM udmurtneft_n.well_stock_hist_ext hs || decode(hs.ora3, null, null, ', ' || 

您正在将一个表别名 (hs) 与另一个 DECODE 连接 - 这不起作用。

如果我们完全删除 FROM 子句，那么代码就会被格式化：
