Database objects include tables, views, sequences, indexes, and synonyms. The tables and views are learned in the previous notes. Database objects, that is, sequences, indexes, and synonyms. Sequence: provides regular values. Database objects that can be used by multiple users to generate unique values are mainly used to provide primary key values. Index: Improves query efficiency. Synonym: alias for the object. In MYSQL and SQL SERVER databases, the

Most customers have their own database servers to manage some of their key data. So what if we need to use this data in our project and the customer is not allowed to insert that data into our project database server? One solution is to create a synonym for some tables or views on the Project database server based on the customer's critical data server. Let me introduce the process I made in the project based on how the remote server view creates syno

You can use multiple methods to back up synonyms. For example, you can directly generate a synonym creation script or use dbms_metadata.get_ddl to extract the definition of synonyms.

OracleSynonymsOracle synonym for (synonyms) similar to view features, but more powerful. Most database objects in an Oracle database, such as tables, views, materialized views, sequences, functions, stored procedures, packages, synonyms, and so on, can be synonyms. There are 2 main purposes: to simplify object access and improve the security of object access .Here's a quick demo:Sql> Conn Scott/tigerConnected.Sql> CREATE TABLE test1 (ID number);Table

Guide: SynonymIt is an alias for database solution objects and is often used to simplify object access and improve object access security. When using synonyms,Oracle DatabaseTranslate it into the name of the corresponding solution object. Similar to a view, synonyms do not occupy the actual storage space. Only the definition of synonyms is saved in the data dictionary. In Oracle databases, most database objects, such as tables, views, synonyms, sequences, stored procedures, functions, JAVA class
