(June 2010) () The specification defines what an 'SQL schema' is; however, databases implement it differently. To compound this confusion the functionality can overlap with that of a parent database. An SQL schema is simply a within a database; things within this namespace are addressed using the member dot '.'

This seems to be a universal among all of the implementations. Serials 2000 Encrypted S2k Update there. A true query is exemplified as such: SELECT * FROM database.schema.table Both a schema and a database can be used to isolate one table, 'foo', from another like-named table 'foo'. Download Chinese Simplified Microsoft Pinyin New Experience Input Style. The following is pseudo code: • SELECT * FROM database1.foo vs. SELECT * FROM database2.foo (no explicit schema between database and table) • SELECT * FROM [database1.]default.foo vs. SELECT * FROM [database1.]alternate.foo (no explicit database prefix) The problem that arises is that former users will create multiple databases for one project. In this context, MySQL databases are analogous in function to PostgreSQL-schemas, insomuch as PostgreSQL lacks off-the-shelf cross-database functionality that MySQL has. Conversely, has applied more of the specification implementing cross-table, cross-schema, and then left room for future cross-database functionality.

MySQL aliases schema with database behind the scenes, such that CREATE SCHEMA and CREATE DATABASE are analogs. It can therefore be said that MySQL has implemented cross-database functionality, skipped schema functionality entirely, and provided similar functionality into their implementation of a database. In summary, PostgreSQL fully supports schemas but lacks some functionality MySQL has with databases, while MySQL does not even attempt to support standard schemas. Oracle has its own spin where creating a user is synonymous with creating a schema. Thus a database administrator can create a user called PROJECT and then create a table PROJECT.TABLE. Users can exist without schema objects, but an object is always associated with an owner (though that owner may not have privileges to connect to the database). With the 'shared-everything' architecture, the same database can be opened by multiple servers concurrently.

This is independent of replication, which can also be used, whereby the data is copied for use by different servers. In the Oracle implementation, a 'database' is a set of files which contains the data while the 'instance' is a set of processes (and memory) through which a database is accessed. Informix supports multiple databases in a server instance like MySQL. It supports the CREATE SCHEMA syntax as a way to group DDL statements into a single unit creating all objects created as a part of the schema as a single owner.
