如何使用带有firebird数据库的C＃中的两个datetimepicker过滤datagridview？

Question

我在Visual Studio 2012中使用C＃，firebird是我的数据库。

在DataGridView中搜索和显示日期范围的代码是什么？ 我的数据库程序可能是错误的。请修复我的程序的这行代码。

 CREATE PROCEDURE LEAVETRANS_DATESRCH(
  BEGIN_DAY SMALLINT,
  BEGIN_MONTH SMALLINT,
  BEGIN_YEAR SMALLINT,
  END_DAY SMALLINT,
  END_MONTH SMALLINT,
  END_YEAR SMALLINT)
RETURNS(
  LEAVETRANS_EMPNAME VARCHAR(50) CHARACTER SET ISO8859_1 COLLATE ISO8859_1,
  LEAVETRANS_LEAVENAME VARCHAR(50) CHARACTER SET ISO8859_1 COLLATE ISO8859_1,
  LEAVETRANS_DAYS DECIMAL(12, 2),
  LEAVETRANS_TIME TIME,
  LEAVETRANS_REASON VARCHAR(500) CHARACTER SET ISO8859_1 COLLATE ISO8859_1)
