我被分配为SSRS报告创建Oracle存储过程。 我想出了以下代码来检索数据：
SELECT DISTINCT
b.branch_name,
cu.unit_name,
c.CLAIM_DESC,
dp.legal_name,
c.claim_number,
c.date_of_loss,
FN_FORMAT_NAME(s.first_name, s.last_name, s.middle_name) AS staff_name,
c.state,
c.county,
cc.first_modified,
dp.policy_search_nbr,
c.city,
col.cause_name,
CASE trim(SUBSTR (cp.last_name || ', ' || cp.first_name, 1, 78))
WHEN ',' THEN SUBSTR (cp.business_name, 1, 78)
ELSE trim(SUBSTR (cp.last_name || ', ' || cp.first_name, 1, 78))
END

--Basically, the code filters for results that fulfill the LIKE criteria for any items in the list

当我在开发数据库的SQL工作表中运行此代码时，它按预期工作，没有错误。 Results from query 但是，当我将代码打包到存储过程中并运行它时， 存储过程不返回任何数据，而是输出以下错误消息：
<html><font color=red>ORA-20000: ORU-10027: buffer overflow, limit of 20000 bytes

出于测试目的，我编写了如下存储过程：
（PG_REPORTS.sps）：

我在网上搜索了一下可能导致这个问题的原因并且空手而归。 同样，我可以让这段代码在SQL工作表中工作，我只是无法让它在存储过程中工作。
我应该解释为什么我按照我的方式实现了以下代码：
JOIN (
SELECT (branch_search_term.COLUMN_VALUE) branch_name
FROM (
TABLE(FN_STRING_SPLITTER('Claim Service Center,Home Office,Northern Region,Property Claims Branch,Property Claim Service Center,Southern Region',','))
) branch_search_term
) branch_search_filter
ON b.branch_name like ('%' || branch_search_filter.branch_name || '%')
基本上，这是我试图实现'LIKE IN'语句的尝试，该语句在Oracle中没有本机实现。数据库中有多个实例，其中分支名称与列表中的项目不完全匹配。
