存储过程示例代码

一、返回结果集

ParamsHelperOracle paramHelper = new ParamsHelperOracle();

paramHelper.Add("UserName", "sys");

paramHelper.Add("returnResult", OracleType.Cursor, ParameterDirection.Output);

--包头
CREATE OR REPLACE PACKAGE Package_TEST IS
TYPE RESULT IS REF CURSOR;
PROCEDURE Select_Test(UserName VARCHAR2,returnResult OUT RESULT);
END Package_TEST;

--包体
CREATE OR REPLACE PACKAGE BODY Package_TEST IS
PROCEDURE Select_Test(UserName VARCHAR2,returnResult OUT RESULT)
AS
sqlstr VARCHAR2(1000);
BEGIN
sqlstr:='select * from all_tables';
IF UserName IS NOT NULL THEN
sqlstr:=sqlstr||' WHERE owner=UPPER('''||UserName||''')';
END IF;

OPEN returnResult FOR sqlstr; --返回结果集

END Select_Test;
END Package_TEST;

二、使用游标

CREATE OR REPLACE PROCEDURE TEST123 AS

CURSOR cur IS SELECT pp.Note FROM Phoneinfo pp;

BEGIN

FOR pi IN cur LOOP

BEGIN

dbms_output.put_line(pi.Note);

END;

END LOOP;

END TEST123;

--执行存储过程

BEGIN

TEST123();

END;
