What does an EXEC SQL stmt do in ABAP? What is the disadvantage of using it?

Ans      To use a Native SQL statement, you must precede it with the EXEC SQL statement, and follow it with the ENDEXEC statement as follows:

EXEC SQL [PERFORMING <form>].
<Native SQL statement>
ENDEXEC.

There is no period after Native SQL statements. Furthermore, using inverted commas (”) or an asterisk (*) at the beginning of a line in a native SQL statement does not introduce a comment as it would in normal ABAP syntax. You need to know whether table and field names are case-sensitive in your chosen database.
