ABAP学习（9）：时间日期操作

ABAP的时间日期操作

    ABAP的日期类型D,是一个8位字符串；时间类型T，是6位字符串。日期实际是一个字符串，格式；‘YYYYMMDD’，可以通过字符串截取获取年月日字符子串。

示例：使用字符串截取出年份、月份等

"日期

DATA:temp_date(8) TYPE C.

temp_date = sy-datum.

WRITE:/ temp_date.

temp_date = temp_date+2(2).

WRITE:/ temp_date.

1、判断日期是否在指定范围

示例：

WRITE:/'测试日期是否在一个时间段中'.

DATA:date1 type d,

     date2 type d.

date1 = '20181201'.

date2 = '20191221'.

 

if sy-datum > date1 and sy-datum < date2.

  WRITE:/ sy-datum,'在范围内'.

else.

  WRITE:/ sy-datum,'不在范围内'.

ENDIF.

2、判断日期是星期几

使用function,’DAY_IN_WEEK’判断一个日期是星期几

示例：

WRITE:'根据日期获取日期星期几'.

DATA: wotnr type p.

CALL FUNCTION 'DAY_IN_WEEK'

  EXPORTING

    DATUM         = sy-datum

 IMPORTING

   WOTNR         = wotnr.

WRITE:/ sy-datum,'是星期',wotnr.

3、根据日期获取日期所在周数

使用function,’DATE_GET_WEEK’,获取日期所在周数

示例：

CALL FUNCTION 'DATE_GET_WEEK'

  EXPORTING

    DATE               = sy-datum

 IMPORTING

   WEEK               = week

4、根据周数获取本周第一天日期

示例：

WRITE:/ '测试WEEK_GET_FIRST_DAY ,通过周数获取，本周第一天'.

DATA: date3 type d.

CALL FUNCTION 'WEEK_GET_FIRST_DAY'

  EXPORTING

    WEEK               = week

 IMPORTING

   DATE               = date3

5、检查日期格式是否正确

示例：

WRITE:/ '测试DATE_CHECK_FAILED ,检查日期是否正确'.

data: date4 type d.

data: date5 type d.

data: date6 type d.

 

date4 = '20101231'.    "需要这种格式日期

date5 = '12/23/2019'.  "不能识别

date6 = '12312010'.    "不能识别

CALL FUNCTION 'DATE_CHECK_PLAUSIBILITY'

  EXPORTING

    DATE                            = date6

 EXCEPTIONS

   PLAUSIBILITY_CHECK_FAILED       = 1

   OTHERS                          = 2.

6、根据输入日期获取所在月最后一天

示例：

WRITE:/ '测试RP_LAST_DAY_OF_MONTHS,获取输入日期所在月最后一天日期'.

data:date7 type d.

CALL FUNCTION 'RP_LAST_DAY_OF_MONTHS'

  EXPORTING

    DAY_IN                  = sy-datum

 IMPORTING

   LAST_DAY_OF_MONTH       = date7

 EXCEPTIONS

    DAY_IN_NO_DATE          = 1.

*   OTHERS                  = 2

7、将输入日期进行计算

示例：

WRITE:/'测试RP_CALC_DATE_IN_INTERVAL ,日期加减 年，月，日 计算'.

data: date8 type d value '20181201'.

data: date9 type d.

CALL FUNCTION 'RP_CALC_DATE_IN_INTERVAL'

  EXPORTING

    DATE            = date8

    DAYS            = 20   "天

    MONTHS          = 0    "月

    SIGNUM          = '-'  "运算符号

    YEARS           = 1    "年

 IMPORTING

   CALC_DATE       = date9.

WRITE:/ date9.

8、获取时间和日期之差

示例：

WRITE:/ '测试SD_DATETIME_DIFFERENCE,获取日期，和时间之间差'.

DATA:date10 type d value '20180911'.

data:date11 type d value '20180922'.

DATA:date12 type p.

data:timediff type p.

 

CALL FUNCTION 'SD_DATETIME_DIFFERENCE'

  EXPORTING

    DATE1                  = date10

    TIME1                  = '080000'   "必须为 hhmmss格式

    DATE2                  = date11

    TIME2                  = '120000'

 IMPORTING

   DATEDIFF               = date12

   TIMEDIFF               = timediff.

9、获取每个月名字

示例：

WRITE:/ '获取每个月的名字'.

DATA: month_name like t247 OCCURS 0 WITH HEADER LINE.

CALL FUNCTION 'MONTH_NAMES_GET'

* EXPORTING

*   LANGUAGE                    = SY-LANGU

* IMPORTING

*   RETURN_CODE                 =

  TABLES

    MONTH_NAMES                 = month_name.

10、获取一段时间内节日日期

示例：

WRITE:/'获取节日表'.

DATA: holidays like iscal_day OCCURS 0 WITH HEADER LINE.

DATA: valid_year_from like SCAL-YEAR.

DATA: valid_year_to like SCAL-YEAR.

DATA: return_code like sy-subrc.

CALL FUNCTION 'HOLIDAY_GET'

 EXPORTING

    HOLIDAY_CALENDAR                 = 'CN'    "获取holiday  calendar id, tcode:scal

    FACTORY_CALENDAR                 = 'CN'   "获取工厂 calendar id ,通过tcode :SCAL

    DATE_FROM                        = '20180102'

    DATE_TO                          = '20181111'
