一、返回一个值
--创建存储过程create or replace procedure sp_hu_test(spcode in varchar2,spname out varchar2)isbeginselect cname into spname from gb_customerinfo where ccode = spcode;end;
//java代码调用和接受返回值public static void main(String[] arg) {try {Class.forName("oracle.jdbc.driver.OracleDriver");Connection cnn = DriverManager.getConnection("jdbc:oracle:thin:@192.168.1.116:1521:cwerp","hu_gbxt", "hu_gbxt");//创建CallableStatementCallableStatement cs = cnn.prepareCall("{call sp_hu_test(?,?)}");cs.setString(1, "082");cs.registerOutParameter(2, oracle.jdbc.OracleTypes.VARCHAR);cs.execute();String cname = cs.getString(2);System.out.println("名字：" + cname);cs.close();cnn.close();} catch (Exception e) {e.printStackTrace();}}}
二、返回多个值
--创建一个包，包里有个游标变量create or replace package mypackage astype sp_cursor is ref cursor;end mypackage;--创建存储过程create or replace procedure sp_proc(carcode in varchar2,sp_coesor out mypackage.sp_cursor)isbeginopen sp_coesor for select * from gb_truck where cardcode = carcode;end;
//注解，这里面的输出参数是个游标类型//java调用存储过程public static void main(String[] arg) {try {Class.forName("oracle.jdbc.driver.OracleDriver");Connection cnn = DriverManager.getConnection("jdbc:oracle:thin:@192.168.1.116:1521:cwerp","hu_gbxt", "hu_gbxt");//创建CallableStatementCallableStatement cs = cnn.prepareCall("{call sp_proc(?,?)}");cs.setString(1, "皖1958707");cs.registerOutParameter(2, oracle.jdbc.OracleTypes.CURSOR);cs.execute();ResultSet rs = (ResultSet)cs.getObject(2);while(rs.next()){System.out.println(rs.getString(1) + " " + rs.getString(2) + " " + rs.getString(4));//关闭 cs.close();cnn.close();} catch (Exception e) {e.printStackTrace();}}}
