在PostgreSQL中执行INSERT语句时出错？

我正在尝试在PostgreSQL数据库中运行以下DML语句：

INSERT INTO HMS_RESERVE_CANCEL_DTL
(DIVISION_CODE,         
  UNIT_CODE,            
  RESERVATION_NO,       
  RESERVATION_DATE,     
  CANCELLATION_NO,
  CANCELLATION_DATE,
  CANCELLED_AT_UNIT,
  CANCELLATION_AMOUNT,
  CANCELLED_BY,
  CANCELLATION_REASON,
  REFUND_AMOUNT,
  POSTED_TO_FAS,
  CANCEL_PER,
  room_type,
  no_of_rooms,
  taxes ) 
values(
  '103',
  '10303',
  'GHA1314HTLRS000157',
  case trim('') when trim('08-05-2013') then null else to_date('08-05-2013','DD-MM-YYYY HH24:MI:SS') end,
  'GHA1314HTLCL000002',
  current_date,
  '10303',
  5200.0,
  '001721',
  'my parsanal',
  '53260.00',
  'N',
  10.0,
  '02',
  '10',
  '10320.0')

上述语句开始执行，但很快就失败，并显示以下错误消息：

ERROR: numeric field overflow
SQL state: 22003
Detail: The absolute value is greater than or equal to 10^4 for field with precision 6, scale 2.

请帮我摆脱这个错误，或者至少给我指出正确的方向。我的表格hms_rserve_cancel_dtl的表格结构如下：

CREATE TABLE hms_reserve_cancel_dtl
(
  division_code character varying(3) NOT NULL,
  unit_code character varying(5) NOT NULL,
  reservation_no character varying(20) NOT NULL,
  reservation_date date NOT NULL,
  cancellation_no character varying(20) NOT NULL,
  cancellation_date date NOT NULL,
  cancelled_at_unit character varying(15) NOT NULL,
  cancellation_amount numeric(7,2),
  cancelled_by character varying(35),
  cancellation_reason character varying(200),
  refund_amount numeric(7,2),
  posted_to_fas character(1) DEFAULT 'N'::bpchar,

  CONSTRAINT hms_reserve_cancel_dtl_div_unit_code_fkey FOREIGN KEY (division_code, unit_code)
      REFERENCES aptdc_units_mst (division_code, unit_code) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE NO ACTION,
  CONSTRAINT hms_reserve_cancel_dtl_reservation_no_fkey FOREIGN KEY (reservation_no, room_type)
      REFERENCES hms_reservation_mst (reservation_no, room_type) MATCH SIMPLE
      ON UPDATE RESTRICT ON DELETE RESTRICT
) 
WITHOUT OIDS;
ALTER TABLE hms_reserve_cancel_dtl OWNER TO postgres;
GRANT ALL ON TABLE hms_reserve_cancel_dtl TO postgres;

数字的小数位数是小数点右侧小数部分的小数位数计数。数字的精度是整数中有效位数的总数，即小数点两侧的位数。所以数字23.5141的精度为6，刻度为4

例如，10123.435不适用于数字4,2

您的taxes字段设计为numeric6，2，这意味着总共有6位数字。小数点前4位，小数点后2位。您提供的值在小数点前有5位，因此不适合使用。

您已将税定义为最多6位，其中2位在小数部分，这意味着9999.99是您可以插入的最大值。在insert中，您尝试插入10320.0，该列太大。

对于精度为6的字段，比例2的绝对值大于或等于10^4意味着什么？如果您尝试将10人插入智能卡，会发生什么情况？没错，这是个例外！我不想被嘲笑，但乍一看，我认为模式需要比插入查询更多的帮助。@DilipReddy请确保。对于所有你问过的问题，你都应该这样做，因为你已经得到了一个可以接受的答案。

create table tmp (
   a numeric (8,5)
   );

/* ok */ insert into tmp values (123.12345); 
/* ok */ insert into tmp values (1.1); 
-- this will result in 1.12346, because precicion is set to 5!
insert into tmp values (1.123456); 

/* owerflow */ insert into tmp values (1000); 
-- because of number gets rounded to 5 decimal numbers:
/* owerflow */ insert into tmp values (999.99999999999999999999);
