Upgrading compiled objects with dbcc upgrade_object

• dbid – specifies the database ID. If you do not specify dbid, all compiled objects in the current database are upgraded.

• dbname – specifies the database name. If you do not specify dbname, all compiled objects in the current database are upgraded.

• compiled_object_name – is the name of a specific compiled object you want to upgrade. If you use the fully qualified name, dbname and database must match, and you must enclose the fully qualified name in quotes. If the database contains more than one compiled object of the same name, use the fully qualified name. Otherwise, all objects with the same name are parsed, and if no errors are found, upgraded.

 

•

check – upgrades all check constraints and rules. Referential constraints

 

 

are not compiled objects and do not require upgrading.

 

•

default – upgrades all declarative defaults and the defaults created with the

 

 

create default command.

 

•

procedure – upgrades all stored procedures.

 

•

rule – upgrades all rules and check constraints.

 

•

trigger – upgrades all triggers.

 

•

view – upgrades all views.

 

 

The keywords check, default, procedure, rule, trigger, and view specify the

 

 

classes of compiled objects to be upgraded. When you specify a class, all

 

 

objects in that class, in the specified database, are upgraded, provided that

 

 

dbcc upgrade_object finds no errors or potential problem areas.

 

•

force specifies that you want to upgrade the specified object even if it

 

 

contains a select * clause. Do not use force unless you have confirmed that

 

 

the select * statement will not return unexpected results. The force option

 

 

does not upgrade objects that contain reserved words, contain truncated or

 

 

missing source text, refer to nonexistent temporary tables, or do not match

 

 

the quoted identifier setting. You must fix these objects before they can be

 

 

upgraded.

 

 

 

Note If set quoted identifiers is on, use single quotes around the keywords. If

 

set quoted identifiers is off, you can use either double quotes or single quotes.

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.
