ABAP语法
新语法~* 可以用来取值一个表中的所有数据和一个表中的部分数据 示例如下 REPORT ZSQL. TYPES: BEGIN OF TY_VBAP, MATNR TYPE VBAP-MATNR, MAKTX TYPE MAKT-MAKTX. INCLUDE STRUCTURE VBAK. TYPES END OF TY_VBAP. DATA : GT_VBAP TYPE TABLE OF TY_VBAP, GW_VBAP TYPE TY_VBAP. SELECT VBAP~MATNR, MAKT~MAKTX, VBAK~* FROM VBAK INNER JOIN VBAP ON VBAK~VBELN = VBAP~VBELN INNER JOIN MAKT ON VBAP~MATNR = VBAP~MATNR AND SPRAS = @SY-LANGU UP TO 10 ROWS INTO CORRESPONDING FIELDS OF TABLE @GT_VBAP. LOOP AT GT_VBAP INTO GW_VBAP . WRITE: GW_VBAP-VBELN ,GW_VBAP-MATNR, GW_VBAP-MAKTX. SKIP 1 . ENDLOOP.
2018.03.31 “取域值
SELECT SINGLE ddtext INTO p_sczt FROM dd07t WHERE domname = p_domname AND domvalue_l = p_domvalue_l.
2018.04.07 取值AL11 的文件目录
DATA:FILE TYPE ESEFTAPPL VALUE 'gettabledata.txt'. CALL 'C_SAPGPARAM' ID 'NAME' FIELD 'DIR_HOME' ID 'VALUE' FIELD FILE.
Append lines of itab1 [ from n1 ] [ to n2 ] to itab2.
WRITE WA-MATNR .
ENDLOOP.
LOOP AT ITAB1 ASSIGNING FIELD-SYMBOL(<FS>). ENDLOOP.

根据一个内表的某个或某几个字段,取出其他内表的数据
REPORT YTEST_FILTER. TYPES:BEGIN OF TY_SPFLI, CARRID TYPE spfli-CARRID, END OF TY_SPFLI. ****需要定义为排序表或者哈希表 因为需要主键 DATA IT_TAB TYPE SORTED TABLE OF TY_SPFLI WITH UNIQUE KEY CARRID. DATA IT_SPLFI TYPE TABLE OF SPFLI . DATA IT_SPLF1 TYPE TABLE OF SPFLI . DATA IT_SPLF2 TYPE TABLE OF SPFLI . ****定义参考表的实际数据 IT_TAB = VALUE #( ( CARRID = 'AA' ) ( CARRID = 'UA' ) ) . SELECT * FROM spfli INTO CORRESPONDING FIELDS OF TABLE IT_SPLFI. ****取到实际表中的数据 IT_SPLF1 = FILTER #( IT_SPLFI IN IT_TAB WHERE CARRID = CARRID ) . ****显示 CL_DEMO_OUTPUT=>DISPLAY( IT_TAB ) . CL_DEMO_OUTPUT=>DISPLAY( IT_SPLFI ). CL_DEMO_OUTPUT=>DISPLAY( IT_SPLF1 ).
********ADD BY CHENHD 20180731 关于 WITH KEY 与 WITH TABLE KEY 的区别。
对于标准表 两者是相同的,对于排序表,前者是线性查找,后者是二分法查找。
1) READ TABLE <ITAB> WITH KEY
This statement always search in linear fashion.
You can use this syntax for any type of table(standard, sorted, hased)
2) READ TABLE <ITAB> WITH TABLE KEY
you can use this syntax only for internal table with primary keys defined
For standard table - Linear search will be used
For sorted table - Binary search will be used.
For Hashed table - Hashing algorithm will be used.
