CREATE proc p_upAppPda(

as
Begin
set @gettime=convert(varchar(10),getdate(),120)
Begin tran t_test
if exists (select a.upNo from v_sumUpQty a left join v_factNum b on a.upNo=b.upNo where convert(decimal(19,0),a.upQty)-convert(decimal(19,0),b.factNum)< 0 and a.upNo=@upNo)

执行方法：一：
Connection conn = db.createConnection();
CallableStatement call = null;
call=conn.prepareCall("{call p_upAppPda(?,?,?,?)}");
call.setString(1, upNo);
call.setString(2, whCode);
call.setString(3, instockNo);
call.registerOutParameter(4,java.sql.Types.INTEGER);
call.executeUpdate();
System.out.println(call.getInt(4)); // 获取存储过程的返回值
方法二（看过没用过，不知道怎么样）：
Connection conn = db.createConnection();
Statement statement = conn.createStatement();
statement = conn.prepareStatement("exec p_upAppPda'" + sql + "'," + 1+ "," + 2);
rs = statement.executeQuery();
