Retrieving SELECT Statement Results within PL/SQL Blocks
Accessing and displaying the output of a SELECT statement embedded within a PL/SQL block requires specific methods. Prior to Oracle 12.1, the standard approach involved using ref cursor variables. This technique necessitates declaring a ref cursor within the PL/SQL block and assigning the SELECT statement's results to it. External tools, such as SQL*Plus, then facilitate the retrieval and display of the data held within the ref cursor.
Oracle 12.1 introduced a more streamlined solution: dbms_sql.return_result()
. This function enables the direct return of an implicit result set from a PL/SQL block, simplifying the process of retrieving and presenting SELECT statement results within PL/SQL procedures.
For a thorough understanding of implicit result sets and the application of dbms_sql.return_result()
, consult the Oracle 12.1 New Features Guide, Oracle Base documentation, and other pertinent resources. These methods empower PL/SQL developers to efficiently manage and display SELECT statement results, mirroring the behavior of standalone SELECT queries.
