调用方法时，会发生错误。括号的数量与打开括号和关闭括号相同。我不明白错误是什么。

多么丑陋的代码！难怪您找不到错误。
我删除了双引号和+符号。然后，格式化程序将显示以下内容：
<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, ', ' ||
您正在将表别名（hs）与另一个DECODE串联-无法使用。
如果我们完全删除该FROM子句，则代码将被格式化：
