List SQL statements allowed and not allowed in a PL/SQL block.
What will be an ideal response?
PL/SQL supports all the Data Manipulation Language (DML) statements such as
INSERT, UPDATE, and DELETE. It also supports the Transaction Control Language
statements ROLLBACK, COMMIT, and SAVEPOINT. You can retrieve data using the
data retrieval statement SELECT. A row of data can be used to assign values to
variables. More than one row can be retrieved and processed using cursors (covered in
the next chapter). PL/SQL statements can use single-row functions, but group functions
are not available for PL/SQL statements. SQL statements in PL/SQL block can still
utilize those group functions.
PL/SQL does not support Data Definition Language (DDL) statements such as CREATE,
ALTER, and DROP. The Data Control Language (DCL) statements GRANT and
REVOKE are not available in PL/SQL either.
