一 Oracle版本: 10g PLSQL: 8.0

二 具体代码如下:

1 类型

CREATE OR REPLACE TYPE ty_str_split IS TABLE OF VARCHAR2 (4000)

2 函数

CREATE OR REPLACE FUNCTION fn_split (p_str IN VARCHAR2, p_delimiter IN VARCHAR2)

RETURN ty_str_split

IS

j INT := 0;

i INT := 1;

len INT := 0;

len1 INT := 0;

str VARCHAR2 (4000);

str_split ty_str_split := ty_str_split ();

BEGIN

len := LENGTH (p_str);

len1 := LENGTH (p_delimiter);

WHILE j < len

LOOP

j := INSTR (p_str, p_delimiter, i);

IF j = 0

THEN

j := len;

str := SUBSTR (p_str, i);

str_split.EXTEND;

str_split (str_split.COUNT) := str;

IF i >= len

THEN

EXIT;

END IF;

ELSE

str := SUBSTR (p_str, i, j - i);

i := j + len1;

str_split.EXTEND;

str_split (str_split.COUNT) := str;

END IF;

END LOOP;

RETURN str_split;

END fn_split;

3 具体应用

CREATE OR REPLACE procedure testsplit(objids in varchar2,message out varchar2)

as

objid varchar2(32);

begin

for x in (select column_value as objid from (SELECT * FROM TABLE (CAST (fn_split (objids, ',') AS ty_str_split)))t) loop

objid := x.objid;

--执行删除或者有关与ID相关的操作

--delete t wher id=objid;

--commit;

message := message || ' ID:' || objid;

end loop;

EXCEPTION

WHEN OTHERS THEN

message :='测试split函数失败...';

end testsplit;

其它运用如下：

select t.column_value,rownum row_ from

table(

cast (

fn_split ('1,2,3,4,5,,7,,', ',') as ty_str_split

)

) t
