Pt-online-schema-change is a tool for Perona company, which solves the problem of not locking tables when changing tables, and does not affect the business, which is the principle:
If there is a foreign key, the foreign key related table is detected according to the value of the Alter-foreign-keys-method parameter, and the corresponding setting is processed.

The JNDI schema provides a standard set of APIs that are independent of the naming system, which are built on the drivers associated with the naming system. This layer helps separate the app from the actual data source, so regardless of whether the app accesses LDAP, RMI, DNS, or other directory services. In other words, Jndi is independent of the specific implementation of the directory service, and the directory can be used as long as there is a dir

Developers have a requirement to move all objects in a schema to another shema. After thinking about it, simply change the schema name? In this way, you do not need to move the data. You are prepared to directly change the data using DDL statements:

This statement was not found at all. After I checked it online, I found that Oracle itself did not provide this function, but
Using rename table in MySQL to quickly and efficiently RENAME a database (schema)
Once a new database (schema) is created in MySQL, it cannot be renamed, therefore, if you need to rename a database, the general practice is to dump the data in the target database and import it to the new database you want to rename. A large number of insert statements are used in MySQL import, DML is widely used. If it is a

When a project is under development, the database should be divided into at least two environments: The Development (TEST) database and the formal database. Some projects are even divided into three databases, such as Dev, Stg, and PRD ), how to synchronize Schemas between several databases is a big challenge.
The replication function of SQL Server 2005 can synchronize data between databases, but it is difficult to synchronize DDL or schema.
