Iv. synonyms(a) What are synonymsA synonym is essentially an alias for a specified schema object. Synonyms provide a degree of security by masking the names and owners of objects and providing location transparency for remote objects in a distributed database. At the same time, the use of synonyms is better, which reduces the complexity of SQL statements of database users. Synonyms allow a base object to be renamed or moved, at which point a

CREATE VIEW statement, Oracle creates the view even if there is a series of cases.The query for a view definition references a table that does not exist.The query for the view definition references columns that are not valid in an existing table.The owner of the view does not have the required permissions.In these cases, Oracle only checks for syntax errors in the CREATE VIEW statement. If the syntax is correct, the view is created and the definition of the view exists in the data dictionary. H

Oracle Database provides the synonym management function. Oracle synonyms are aliases of database solution objects. They are often used to simplify object access and improve object access security. In Oracle databases, most database objects, such as tables, views, synonyms, sequences, stored procedures, functions, JAVA classes, packages, and so on, can be defined by the database administrator as needed.

Tags: lap update set for TIME range Dex minimum PreMany applications require a unique number to be used as the primary key value, so you can build code in your application to handle this requirement, or you can use a sequence to produce a unique number. If you want to improve the performance of some queries, you should consider creating an index, or you can enforce uniqueness on the collection of columns or columns with an index. You can use synonyms to provide an alternative name for the object

1. Synonyms: In a distributed database environment, to identify a database object, you must specify the host name, the server name, the owner of the object, and the object name. This undoubtedly increases the access difficulty of the visitor. You can create synonyms for database objects to provide a simple, unique name that identifies the database object in order to use the database object for different users. For example, let's say that we have a table table in the database for a user, so whe

Questions raised In my new job, I faced the problem of archiving the tables that were created in the product database, because as the database grows, it needs to be moved now. At the same time, these archived tables are used for several tasks and are invoked in the application's code. Moving them in this way is a very complicated process. I want to find a way to minimize the amount of work that developers have to do, because they have very limited time. Can you tell me the best way to file the

synonymous names 1. Introduction Just like using a view to perform operations without directly relying on a base table, you can use a synonym name to achieve this purpose. Unlike a view, a synonym name can be applied not only to table naming, but also to views, sequences, stored procedures, functions, and packages, therefore, it is widely used. The inconvenience of using a synonymous name is that it cannot

Today, let's take a look at how to manage database objects in the orcale database. I. Synonyms 1. Solution The solution is a collection of database objects. The solution contains various objects (tables, views, indexes, synonyms, sequences, database connections, etc ). Generally, a user corresponds to a solution. Of course, the user can have other solutions. 2. Synonyms Synonyms are the aliases of solution objects. They are commonly used to simplify objects and improve Object Access
