To indicate the ABAP processor that the following statement is native SQL statement and hence to bypass R/3 database interface, we need to precede such statement by EXEC SQL and followed by ENDEXEC as shown below: The addition PERFORMING is applicable only with the SELECT native SQL statement (also, not applicable in OO ABAP context) and calls the routine ABAP_ROUTINE after each successful call of SELECT statement.
This addition is further explained in section “Selecting data from a table”.
An implicit cursor FOR loop has a SELECT statement querying a table or a view instead of lower bound and upper bound values in the case of the traditional FOR loops.
The cursor index of the FOR loop acts as a pointer to the result set processed by the associated SELECT statement in the private memory area known as the context area in the PGA.
When a variable is used with dbs, it should be preceded by a colon ‘:’.
This representation of variable in EXEC SQL statement is called as Host Variable.

Open SQL is used to access database table defined in ABAP dictionary irrespective of the database platform the R/3 system is based.
In contrast, native SQL statements are used to access database tables not defined in ABAP dictionary and hence allow us to integrate data not part of R/3 system.
They say they used row-by-row processing the lock being held on these row for long ? Is this an acceptable justification to use cursor ?
