SQL 23c

Oracle Database 23c introduces a powerful enhancement to the RETURNING clause for DML statements, enabling developers to retrieve both old and new values directly within UPDATE statements. This feature streamlines application development, improves performance, and simplifies tasks like auditing and change data capture (CDC).

Oracle Database 23c introduces significant enhancements to the simple CASE statement and expression, offering increased flexibility and alignment with the SQL:2003 standard. These enhancements include: Dangling Predicates and Multiple Choices or Conditions in a Single WHEN Clause. We will demonstrate those enhancements in this article.

Oracle 23c introduces a powerful extension to the VALUES keyword, enabling you to materialize rows of data directly within various SQL statements. This streamlines code, improves readability, and offers flexibility in data manipulation.

Prior to Oracle Database 23c, representing logical values like TRUE and FALSE in tables was, well, less than straightforward. We resorted to creative juggling acts, employing numbers, characters, or even entire table structures to mimic binary states. The result? Code shrouded in cryptic workarounds, data prone to misinterpretations, and performance begging for optimization. With 23c, Oracle finally embraces

Oracle Database 23c introduces enhancements to GROUP BY and HAVING clauses, empowering developers to write more concise, readable, and maintainable SQL queries. These improvements include: Pre-23c Restrictions: Oracle 23c Empowers Simplicity: Column Aliases in Action: Column Positions in GROUP BY: HAVING with Aliases: Conclusion The advancements in GROUP BY and HAVING clauses within Oracle 23c offer benefits for

Oracle Database 23c introduces a powerful new feature that empowers developers and DBAs to maintain data integrity and simplify application logic: the ability to define columns as DEFAULT ON NULL for update operations. This enhancement builds upon the existing DEFAULT ON NULL functionality for insert operations, extending its benefits to update scenarios as well.

In Oracle database 23c, you can pass INTERVAL data types to the SUM and AVG aggregate and analytic functions. This feature streamlines operations involving time intervals, making it more convenient for developers and data analysts. In addition to that, this feature avoids potentially performance-intensive conversions, leading to faster query execution. In Oracle Database, INTERVAL data types represent a
