今天学习一下内表的READ TABLE 表达式在ABAP 7.4之后的语法: SELECT * FROM mara INTO TABLE @DATA(gt_mara) UP TO 10 ROWS. DATA gt_mara_sort TYPE SORTED TABLE OF mara WITH UNIQUE KEY primary_key COMPONENTS matnr. "旧语法 DATA LV_MATKL TYPE MARA-MATKL. READ TABLE GT_MARA INDEX 1 INTO D...
READ TABLE itab "根据第二索引进行搜索,会比上面程序快 WITH TABLE KEY second_key COMPONENTS col3 = ... col4 = ... ASSIGNING ... ... "在循环内表的Where条件中,如果内表不是排序内表,则不会使用二分搜索,如果使用SORTED KEY,则循环时,是否会用到二分搜索?LOOP AT itab USING KEY second_key...
可以在READ TABLE itab, LOOP AT itab, MODIFY itab, DELETE itab内表操作语句中通过WITH [TABLE] KEY … COMPONENTS或者USING KEY选项指定key_name来使用第二索引 可以在INSERT itab与APPEND语句中通过USING KEY选项来使用源内表的第二索引 DATA itab TYPE HASHED TABLE OF dbtab WITH UNIQUE KEY col1 col...
DATA sflight_tab TYPE STANDARD TABLE OF sflight WITH EMPTY KEY WITH UNIQUE SORTED KEY dbkey COMPONENTS carrid connid fldate. ... READ TABLE sflight_tab WITH KEY dbkey COMPONENTS carrid = '...' connid = '...' fldate = '...' ...
WITH NON-UNIQUE SORTED KEY sort_key COMPONENTS table_line. itab = VALUE #( ( 2 ) ( 5 ) ( 1 ) ( 3 ) ( 4 ) ). DATA(output) = ``. DATA(idx) = lines( itab ). WHILE idx > 0. READ TABLE itab INDEX idx USING KEY sort_key ...
ABAP READ TABLE使用BINARY SEARCH如题,read table使用binary search,with key有多个字段的时候,寻找数据的内部逻辑是怎样的比如有内表(按A,B已排好序)T_DATAA B C1 1 11 2 22 1 32 2 42 3 53 1 63 2 73 3 8现在用如下语句查找READ TABLE T_DATA INTO W_DATA WITH KEY A='2' B = '3' BINA...
Specifying Components, with the restriction that after TRANSPORTING, no attributes of classes can be addressed using the object component selector. ABAP_EXAMPLE_VX5 The READ statement uses a WHILE loop to read all lines of the table sflight_tab one after the other using the primary table...
Example 4 – Reading table entry with components As you see here, you can read the entry and access the component of the result workarea directly, no need of temporary work area. * Multiple ComponentsTYPES:BEGIN OFty_data,kunnrTYPEkunnr,name1TYPEname1,ort01TYPEort01,land1TYPEland1,END OF...
DESCRIBE FIELD <f> [LENGTH <l>] [TYPE <t> [COMPONENTS <n>]][OUTPUT-LENGTH <o>] [DECIMALS <d>][EDIT MASK <m>]. 将由语句的参数指定的数据对象<f>的属性写入参数后的变量。 DESCRIBE FIELDS 语句具有下列参数: 1.3.1 确定字段长度
Any controller having added the name of the static component usage to the list of used controllers / components can then create additional usages of the same component. Each component usage must have a unique name. I will reuse the component created in the blog Step by Step to create UI ...
