Often, it is good database design practice to split a many-to-many relationship between two tables into two one-to-many relationships involving three tables. You do this by creating a third table, called a junction table or a relationship table, that has a primary key and a foreign key for each of the other tables.


How do I create multiple tables into one database?

Using the "CREATE SCHEMA" command you can combine multiple DDL steps into a single statement. As a result, the failure of a single part causes all commands within the "CREATE SCHEMA" to be rolled back. CREATE SCHEMA is limited to creating tables, views and issuing grants.

Can a database have multiple tables with same name?

You simply can't. You must prefix your table or find a different name.

Is it better to have multiple tables?

In many cases, it may be best to split information into multiple related tables, so that there is less redundant data and fewer places to update.

Can you have multiple tables in from SQL?

In SQL we can retrieve data from multiple tables also by using SELECT with multiple tables which actually results in CROSS JOIN of all the tables. The resulting table occurring from CROSS JOIN of two contains all the row combinations of the 2nd table which is a Cartesian product of tables.
