java 调用 Oracle包后 执行成功 但是要修改的东西没有变
Oracle package

CREATE OR REPLACE PACKAGE PKG_REPORT AS

FUNCTION GET_VALUE RETURN VARCHAR2;

PROCEDURE SET_VALUE(PS_TIME IN VARCHAR2);

END PKG_REPORT;


CREATE OR REPLACE PACKAGE BODY PKG_REPORT IS

M_V VARCHAR2(50);

PROCEDURE SET_VALUE(PS_TIME IN VARCHAR2) IS BEGIN M_V:=PS_TIME; END;

FUNCTION GET_VALUE RETURN VARCHAR2 IS BEGIN RETURN M_V; END;

END PKG_REPORT;



[code=Java][/code]
String sDBDriver="oracle.jdbc.driver.OracleDriver";
String sConnStr="jdbc:oracle:thin:@192.168.0.50:1521:dtcloud1";
Class.forName(sDBDriver);
Connection conn=DriverManager.getConnection(sConnStr,"dsm","dsm");
CallableStatement call=conn.prepareCall("{call pkg_report.SET_VALUE(?)}");
call.setString(1, "135546546545");
call.executeQuery();


这个执行成功了，但是M_V VARCHAR2 的值没改掉

求解~

修改时用的update（）方法，executequery()只是查询不是修改
