实现Oracle的字符串分割(split)[摘录]

创建 Table Type

CREATE OR REPLACE TYPE type_splitStr IS TABLE OF VARCHAR2 (4000);

Split函数（splitStr）

 1 create or replace function splitStr(p_list varchar2,p_sep varchar2 := ',') return type_splitStr pipelined 
 2  IS 
 3  l_idx pls_integer;
 4  v_list varchar2(50) := p_list; 
 5  begin 
 6       loop 
 7            l_idx := instr(v_list,p_sep); 
 8            if l_idx > 0 then 
 9                pipe row(substr(v_list,1,l_idx-1)); 
10                v_list := substr(v_list,l_idx+length(p_sep)); 
11            else 
12                 pipe row(v_list); 
13                 exit; 
14            end if; 
15       end loop; 
16 
17       return; 
18  end splitStr;

测试：

select * from table(splitStr('971FA4W3006586|971FA4W3006686','|'))
