本文介绍了如何在单个url参数中传递多个值，并通过示例代码展示了在Oracle过程内处理这种参数的方法，包括创建用户定义类型并在where子句中应用。
为单个url参数传递多个值
下面的示例代码旨在显示在单个参数中接受值列表的用法，并在过程内的where子句中对其进行处理。
步骤1：-首先创建用户定义的类型。
CREATE OR REPLACE TYPE SPLIT_TBL AS TABLE OF VARCHAR2(32767);CREATE OR REPLACE FUNCTION SPLIT
(
P_LIST VARCHAR2,
P_DEL VARCHAR2 := ','
) RETURN SPLIT_TBL PIPELINED
IS
L_IDX PLS_INTEGER;
L_LIST VARCHAR2(32767) := P_LIST;
L_VALUE VARCHAR2(32767);
BEGIN
LOOP
L_IDX := INSTR(L_LIST,P_DEL);
IF L_IDX > 0 THEN
PIPE ROW(SUBSTR(L_LIST,1,L_IDX-1));
L_LIST := SUBSTR(L_LIST,L_IDX+LENGTH(P_DEL));
ELSE
PIPE ROW(L_LIST);
EXIT;
END IF;
END LOOP;
RETURN;
END SPLIT;
