Whenever more than one line needs to be read, inserted or deleted from a database table, it is more efficient to work with an internal table than to read, insert or delete the lines one by one inside a loop.


== Noncompliant Code Example

----
LOOP AT TAB INTO TAB_WA.
  INSERT INTO CUSTOMERS VALUES TAB_WA.
ENDLOOP.
----


== Compliant Solution

----
INSERT CUSTOMERS FROM TABLE TAB.
