What type of SQL statement must you use execute immediate?
dynamic SQL statement

Can we use execute immediate in forall?
You can put an EXECUTE IMMEDIATE statement with the RETURNING BULK COLLECT INTO inside a FORALL statement. You can store the results of all the INSERT , UPDATE , or DELETE statements in a set of collections.
Which of the following packages would you use to set profile for the running program in PL SQL code?
DBMS_PROFILER
The DBMS_PROFILER package was introduced in Oracle 8i to allow developers to profile the run-time behaviour of PL/SQL code, making it easier to identify performance bottlenecks which can then be investigated more closely.
What is bulk bind in Oracle?
Bulk Binds are a PL/SQL technique where, instead of multiple individual SELECT, INSERT, UPDATE or DELETE statements are executed to retrieve from, or store data in, at table, all of the operations are carried out at once, in bulk.
Can we use execute immediate cursor?
You can’t execute DML or PL/SQL code insight of a CURSOR declaration. Only a SELECT Statement is valid for a CURSOR declaration.
How Bulk collect improves performance?
Since the BULK COLLECT fetches the record in BULK, the INTO clause should always contain a collection type variable. The main advantage of using BULK COLLECT is it increases the performance by reducing the interaction between database and PL/SQL engine.
Why We Use execute immediate in Oracle?
EXECUTE IMMEDIATE enables execution of a DML or DDL statement which is held as a string and only evaluated at runtime. This enables one to dynamically create the statement based on program logic. EXECUTE IMMEDIATE is also the only way you can execute DDL within a PL/SQL block.
Why do we use execute immediate in Oracle?

How does bulk collect into with execute immediate work?

How does bulk collect work in PL / SQL?
A cursor loop in Oracle 10g and later may force the PL/SQL engine to bulk collect 100 rows at a time, allowing your code to handle rows without having to set up and run the bulk collect procedure.
How to use execute immediate and fetch in SQL?
Both the EXECUTE IMMEDIATE and the FETCH statements can be used populate collections from dynamic queries using the BULK COLLECT clause, as shown in the dynamic_bulk_collect.sql script listed below. The results of the dynamic_bulk_collect.sql script show that both the FETCH and the EXECUTE IMMEDIATE methods return the same results.
What are the limitations of bulk collect in SQL 8i?
A well-documented limitation of BULK COLLECT in 8i was that each column fetched from a SQL statement or cursor required its own index-by table or collection. This meant that many types needed to be declared and many index-by tables or collections maintained, which could be very code-intensive.
