Instead of the DO loop, a If ALL FIELDS is specified, all fields are compared. He has a landing page of sorts for his various blogs on the topic here: Credit also goes to Naimesh Patel for his useful explanations and examples on ABAP 7.40. The second calculation shows how this can be avoided by using an LOOP AT ITAB2 FROM IDX. I also tested to do a manual BINARY SEARCH and start looping from that position until i found a different combination for my key fields, this is a solution i usually used when i didnt understand how ABAP works, i surprisingly found that it performs slightly better, may be useful if you need to squeeze until the last bit of performance. Before the Loop, T_DATA[] is sorted by the key I use in the read statement. structure (ls_line3) which is based on ls_line2 but overwritten by matching, A string template is enclosed by two characters , FILTER type( itab [EXCEPT] [IN ftab] [USING KEY keyname], ( CORRESPONDING #( RS_CONFIG_PERS_DATA EXCEPT PERS_FOR_USER ), Of course your "classic code" is better not just because the above is longer but also because the above will not work if there is ever a change to the structure, https://blogs.sap.com/2018/09/13/abaps-new-syntax-tips-from-experience/, with UNTIL or WHILE for conditional iterations.

I've ran this through different scenarios before and, like Kerem Koseoglu , arrived at a conclusion that on average, SORTED table performance is not worse than when using BINARY SEARCH. How to get the row count via ADBC native SQL? Huh, seems I missed this blog so far (found it now via https://blogs.sap.com/2018/09/13/abaps-new-syntax-tips-from-experience/ ) - this seems like a very helpful resource, thanks! Where non-developers have spent years slowly learning what is now legacy syntax they will now be impeded when trying to read/debug code in new syntax. When using LOOP WHERE the BINARY SEARCH is performed under the hood, so for newbies it can become even more complex to understand when and why ABAP is doing this search optimal for you. For some reason, the read fails a lot of time even if it has same key in both tables. sy-tabix is set to the row number of the entry in the primary or secondary table index used.

If the primary table itab is a functional operand position . DATA(idx) = lines( itab ). SELECT * FROM t001 INTO TABLE @DATA(lt_t001). Presumably where one line of code in the new syntax does the work of multiple lines in the old then the new syntax will be quicker as it will be optimized for the specific function it is carrying out. data : lt_kunnr TYPE HASHED TABLE OF kna1 WITH UNQUE KEY kunnr lt_cov_entry[] is inline declared in a SELECT t_patient_list[] is declared as exporting table in the function and it has ABAP Dictionary structure.

This list will help me to wrap my head around the (no longer really) new options to write ABAP-statements. I was suggesting Vishal that multiple entries will not work for the type ty_ord since it represents a flat structure and we can use multiple entries only if we use a table type of ty_ord. Your examples are really straightforward, easy to understand and useful for "real life" developers. assigned a field name). Given structures ls_line1 & ls_line2 defined and populated as above. In Oracle SQL developer, how can I find the number of rows in a certain table?

Eclipse ADT "quick fixes" to declare the variable explicitly (DATA BEGIN OF ), change DATA into TYPES, and use that type name (well, you could type your parameter with TYPE STANDARD TABEL, but the probably would not be useful in most cases). Wow, this ABAP 7.40 Quick Reference is awesome, giving old/new examples for many features like Inline Declarations, Table Expressions, Value Operator VALUE, etc. You can use the system variable sy-tabix if you work with internal tables. True ('X'), IF NOT My_Class=>return_boolean( ). " BINARY SEARCH can offer a marginal improvement in runtime while it's effect on the code maintenance and "cleanliness" is far worse.
