'[^,]+', 1, LEVEL) IS NOT NULL;

这给出了 ORA-01704: string literal too long。

我理解传递的字符串超过 4000 个字符的原因，但我想在 PL/SQL 块中处理这么多记录。字符串只不过是从 UI 传递到 oracle 过程的逗号分隔值。

例如：

00102034334:15:11-JUN-13 ~ ord_no:order_line_no:Date (1 order can have many order lines , parent-child relationship)

当我在 SQL 上使用 into 子句时，在 PL/SQL 表类型变量中。

这对我来说是个错误。

我该怎么走？在这种情况下，是否有任何其他方式可以将参数从 UI 传递到 Oracle。

PL/SQL 字符串最多可以包含 32767 个字符，如果要使用 PL/SQL 处理字符串，请在过程中使用 varchar2(32767)。如果 32767 个字符仍然太短，只需将您的字符串作为 clob 传递，CLOB 的长度是无限的。

declare
  long_varchar varchar2( 32767 );
  v_clob clob;
begin
  long_varchar :=

对于非常长的字符串，将要处理的数据存储在 CLOB 类型变量中，并通过传递 CLOB 类型变量使用 REGEXP_SUBSTR 解析数据。

declare
v_clob clob;
