Bit shifts with ABAP

阅读更多关于 Bit shifts with ABAP

问题 I'm trying to port some Java code, which requires arithmetic and logical bit shifts, to ABAP. As far as I know, ABAP only supports the bitwise NOT, AND, OR and XOR operations. Does anyone know another way to implement these kind of shifts with ABAP? Is there perhaps a way to get the same result as the shifts, by using just the NOT, AND, OR and XOR operations? 回答1: Disclaimer: I am not specifically familiar with ABAP, hence this answer is given on a more general level. Assuming that what you

sap hana - select top expression

阅读更多关于 sap hana - select top expression

问题 I have a problem with a stored procedure. The procedure gets as an argument the number of rows needed, but the following does not work in HANA: SELECT TOP :NUM_OF_ROWS * FROM TABLE_NAME I read that TOP in HANA only receives a number, not an expression. Is there another way to do this? My solution for the moment is to select everything and delete the unneeded records on the service, but it's not very efficient. 回答1: Instead of TOP n you can use the LIMIT n option. That one can bind variables.

更多内容关注公众号：SAP Technical 各位可以关注我的公众号：SAP Technical 其实自建SE16N功能，并让它可以直接修改数据库表数据，其原理与在SE16N中DEBUG修改EDIT参数的原理一样，只是在调用标准的函数组时把入参稍作修改即可。实现代码如下： REPORT zse16n. PARAMETERS:p_tabnm TYPE dd02l-tabname OBLIGATORY. AT SELECTION-SCREEN. SELECT COUNT(*) FROM dd02l WHERE tabname = p_tabnm. IF sy-subrc <> 0. MESSAGE '表不存在' TYPE 'E'. ENDIF. START-OF-SELECTION. CALL FUNCTION 'SE16N_INTERFACE' EXPORTING i_tab = p_tabnm i_edit = 'X' "参数修改 i_sapedit = 'X' "参数修改 EXCEPTIONS no_values = 1 OTHERS = 2. IF sy-subrc <> 0.

阅读更多关于 XML parsing with SAX | how to handle special characters?

问题 We have a JAVA application that pulls the data from SAP, parses it and renders to the users. The data is pulled using JCO connector. Recently we were thrown an exception: org.xml.sax.SAXParseException: Character reference "&#00" is an invalid XML character. So, we are planning to write a new level of indirection where ALL special/illegal characters are replaced BEFORE parsing the XML. My questions here are : Is there any existing(open source) utility that does this job of replacing illegal
