Parameter
Description
Basic Information
On the Basic Information Page, you need to set the table name, add remarks (optional), choose the storage engine (default is InnoDB; for other engines, refer to the actual console), set the character set, set validation rules, set row format, set average row length, set minimum row length, and set maximum row length.
Column Information
On the Column Information Page, you can use add, delete, insert, move up, and move down operations to configure the table's columns.
Index
On the Index Page, you can add new indexes. It helps quickly locate data rows with specific data values. Refer to the console for the specific supported index types and indexing methods.
Foreign Key
On the Foreign Key Page, you can add new foreign keys. Foreign keys are used to establish constraints on relationships between tables. A foreign key constraint specifies a column in one table whose values must match the values in a column of another table. This matched column is usually the primary key of the other table.
Partition
On the Partition Page, you can improve query performance and simplify data maintenance and management by dividing table data into multiple partitions.
Note:
For more information on the character set and sorting rule, see MySQL documentation.
