MyISAM permits data and index files to grow up to 256TB by default, but this limit can be changed up to the maximum permissible size of 65,536TB (2567 − 1 bytes)."
You can create up to 2,147,483,647 tables in a database, with up to 1024 columns in each table.
The MySQL maximum row size limit of 65,535 bytes is demonstrated in the following InnoDB and MyISAM examples. The limit is enforced regardless of storage engine, even though the storage engine may be capable of supporting larger rows.
The sum of the number of all objects in a database can't exceed 2,147,483,647. Objects include tables, views, stored procedures, user-defined functions, triggers, rules, defaults, and constraints. The sum of the number of all objects in a database can't exceed 2,147,483,647.
How many tables can be created in a mysql database ?
MySQL has no limit on the number of databases. The underlying file system may have a limit on the number of tables. Individual storage engines may impose engine-specific constraints. InnoDB permits up to 4 billion tables.
And how many columns can be created in a mysql table ?
There is a hard limit of 4096 columns per table, but the effective maximum may be less for a given table. The exact limit depends on several interacting factors.
How many rows can be inserted into a mysql table ?
The number of rows is limited by the maximum size allowed for a table. This is OS-dependent. You can impose a limit on the number of rows by setting MAX_ROWS at table creation time.
