no its in ABAP

In ABAP, the fastest way to move one internal table to another internal table is to use the ASSIGNING clause of the LOOP statement. This method avoids the overhead of copying data row by row, and directly assigns the internal table reference to the new table. Here is an example code snippet:

DATA: lt_table1 TYPE TABLE OF <data_type>,
      lt_table2 TYPE TABLE OF <data_type>.

" Fill the first table with data

" Move the data from table1 to table2
LOOP AT lt_table1 ASSIGNING FIELD-SYMBOL(<fs>).
  APPEND <fs> TO lt_table2.
ENDLOOP.

In this code, the "LOOP AT lt_table1 ASSIGNING FIELD-SYMBOL(<fs>)" statement assigns a field symbol <fs> to each row of the internal table lt_table1. The "APPEND <fs> TO lt_table2" statement then directly appends the row pointed to by <fs> to the new internal table lt_table2. This method is faster and more efficient than using a separate loop to copy each row of the table.
