Moreover it helps us keep a track on our query just in case if we ever want to change or modify it. These in turn will get substituted accordingly during the runtime. We already know that we can easily control the context switches through the use of bulk data processing. Again it is an Optional Clause. But to use this way, the datatype and number of variable that to be used at a run time need to be known before. All legitimate Oracle experts publish their.
Furthermore if your statement returns more than one row of results then there are other ways. Thereafter return its result if there is any.

Follow the link for additional information on. I like the later approach of assigning the query into the variable. It will be used for referencing the nested table in our program. And later used that variable with Execute Immediate. If the output is aggregated, it can be placed into a regular variable.
You can also watch the detailed explanation of the above syntax in the corresponding video Example of Execute Immediate statement. It returns the number of records processed.
