逗号分隔的字符串转换为行数据(collection) CREATE OR REPLACE FUNCTION "GET_STR_TAB" (v_str in varchar2) return table_str pipelined as v_new_str varchar2(8000); begin if v_str is null then pipe row(-1); else v_new_str:=replace(replace(v_str,chr(10),‘‘),chr(9),‘‘); while 1=1 loop if instr(v_new_str,‘,‘)=0 then pipe row(to_number(v_new_str)); exit; else pipe row(to_number(substr(v_new_str,1,instr(v_new_str,‘,‘)-1))); v_new_str:=substr(v_new_str,instr(v_new_str,‘,‘)+1); end if; end loop; end if; return; end; 另还要有一个type类型 CREATE OR REPLACE TYPE "TABLE_STR" as table of number
