求个物集345搭建需要的数据库函数
搭建需要的数据库函数谁有啊 ----------------------------------------------------------1

CREATE OR REPLACE TYPE "WJTEST"."TABLETYPE" as table of varchar2(32676);

CREATE OR REPLACE FUNCTION "WJTEST"."SPLIT" (p_list CLOB, p_sep VARCHAR2 := '|')
RETURN tabletype
PIPELINED
/**************************************
* Name: split
* Author: Sean Zhang.
* Date: 2012-09-03.
* Function: 返回字符串被指定字符分割后的表类型。
* Parameters: p_list: 待分割的字符串。
p_sep: 分隔符，默认逗号，也可以指定字符或字符串。
* Example: SELECT *
FROM users
WHERE u_id IN (SELECT COLUMN_VALUE
FROM table (split ('1,2')))
返回u_id为1和2的两行数据。
**************************************/

--DDL for Function SPLITSTR

/**************************************
52* Name: splitstr
53* Author: Sean Zhang.
54* Date: 2012-09-03.
55* Function: 返回字符串被指定字符分割后的指定节点字符串。
56* Parameters:str: 待分割的字符串。
57 i: 返回第几个节点。当i为0返回str中的所有字符，当i 超过可被分割的个数时返回空。
58 sep: 分隔符，默认逗号，也可以指定字符或字符串。当指定的分隔符不存在于str中时返回sep中的字符。
59* Example: select splitstr('abc,def', 1) as str from dual;得到 abc
60 select splitstr('abc,def', 3) as str from dual;得到 空

感谢大佬: 345族导入数据库后， 不需要配置函数就可以用了
