私のコード:

DECLARE report_date DATETIME;
set report_date='2013-01-17 00:00:00';

SELECT  *
  FROM `NMPP`.`capacitypersecond` 
  WHERE `StreamDT` >=report_date and `StreamDT` < '2013-01-18 00:00:00'  ;

SELECT  *
  FROM `NMPP`.`capacityperHr` 
  WHERE `StreamDT` >=report_date and `StreamDT` < '2013-01-18 00:00:00'  ;

SELECT  *
  FROM `NMPP`.`capacityperDay` 
  WHERE `TJLDate` >=report_date and `TJLDate` < '2013-01-18 00:00:00'  ;
