In a loop, a statement block is executed several times in succession. There are four kinds of loops in ABAP:· Unconditional loops using the DO statement.· Conditional loops using the WHILE statement.· Loops
When we develop Sap abap applications, it is hard to avoid to use 'Loop' key words to implement our business requirments, even it is very often to use two loops or using 'read table' in a loop. Under this condition, many loops or using 'read table' in loops could occur very bad pe...
In ABAP coding many performance problems are related to the handling of internal tables. Especially in the case of nested loops on two large tables, it is important for the runtime of the inner operation to scale faster than linear, otherwise the complete nested loop would show a quadratic sc...
SPFLI on miniSAP). My times, in microseconds:Select: 96439Nested: 31Indexed: 59Other: 31This was for 6 SCARR and 10 SPFLI records.So this test would show that a Nested loop was the best option. (James's 'Other' logic does not include the required sort).I tried to find ...
f4abap "...both being just an iteration over pointers." That is not fully correct. Fields-symbols are dereferenced during the assignment and not with every call and do not support polymorphism like references. Therefore they are fast in loops. ...
In this tutorial, you shall learn about loops in PHP, different loop statements available in PHP, and tutorials for each of them.

This reads the lines of the table one by one as specified in the result part of the LOOP statement. You can then process them in the statements within the LOOP - ENDLOOP control structure. You can either run the loop for all entries in the internal table, or restrict the number of ...
