dbcc upgrade_object

Upgrading compiled objects with dbcc upgrade_object

For example, if you have a user-defined stored procedure named list_proc, the presence of source text for list_proc is verified when you upgrade to Adaptive Server 15.0. The first time list_proc is invoked after the upgrade, Adaptive Server detects that the list_proc compiled object has not been upgraded. Adaptive Server recompiles list_proc, based on the source text in syscomments. The newly compiled object is then executed.

Upgraded objects retain the same object ID and permissions that they used before being upgraded.

Compiled objects for which the source text was hidden using sp_hidetext are upgraded in the same manner as objects for which the source text is not hidden. For information on sp_hidetext, see the Reference Manual:Procedures.

Note If you are upgrading from 32-bit installations to use a 64-bit Adaptive Server, the size of each 64-bit compiled object in the sysprocedures table in each database increases by approximately 55 percent when the object is upgraded. The pre-upgrade process calculates the exact size. Increase your upgraded database size accordingly.

To ensure that compiled objects have been upgraded successfully before they are invoked, you can upgrade them manually using the

command. For details, see “Finding compiled object errors before production” on page 110.

Finding compiled object errors before production

Changes made in earlier versions of Adaptive Server may cause compiled objects to work differently in version 12.5.x and later. You can use dbcc upgrade_object to find the following errors and potential problem areas that may require manual changes to achieve the correct behavior:

•Reserved word errors

•Missing, truncated, or corrupted source text

•Quoted identifier errors

•Temporary table references

•select * potential problem areas

15.0.2 specifications

Sybase 15.0.2, a product of the Sybase corporation (now SAP), is a relational database management system (RDBMS) that provides robust solutions for data management, security, and performance. This version builds upon its predecessors, offering improved features and enhancements that cater to both enterprises and developers.

One of the standout features of Sybase 15.0.2 is its advanced performance capabilities. The version introduces optimization enhancements such as the Query Optimizer, which is designed to ensure efficient execution of complex queries. This optimizer analyzes SQL statements and tables to choose the most efficient means of retrieval, thus reducing execution time and improving the overall performance of the database.

Sybase 15.0.2 supports improved scalability, allowing organizations to handle increased workloads without significant changes to their infrastructure. This scalability is crucial for businesses experiencing growth, as it ensures that performance remains consistent and reliable.

Another notable characteristic is the robust security architecture integrated within Sybase 15.0.2. The system includes features like data encryption, user authentication, and authorization mechanisms, making it suitable for environments that handle sensitive information. Database administrators can implement fine-grained access controls to manage user permissions effectively.

Moreover, Sybase 15.0.2 boasts support for a wide range of programming languages and frameworks. This versatility allows developers to build applications using their preferred tools, promoting productivity and ease of integration into existing systems. The database management system also supports various platforms, including Windows and UNIX, enabling diverse deployments across different environments.

In addition to these technological enhancements, Sybase 15.0.2 emphasizes data integrity through its robust transaction management system. It implements the ACID properties (Atomicity, Consistency, Isolation, Durability) to ensure that all database transactions are processed reliably, thereby maintaining the integrity of data even in high-transaction scenarios.

In conclusion, Sybase 15.0.2 is a feature-rich RDBMS that combines performance, scalability, security, and flexibility. Its advanced capabilities not only enhance data management for organizations but also provide a solid foundation for developers seeking to create efficient and secure applications. The improvements in this version make it a compelling choice for enterprises looking to optimize their database operations in an increasingly data-driven world.
