Retrieving Table Schema in MySQL
When working with tables in a MySQL database, it's often necessary to view their schema. Fortunately, there are two convenient commands for this purpose:
1. describe
The describe command displays a formatted table showing the following information for each column:
- Name
- Data type
- Default value
- Null constraint
- Key constraint
- Extra information (e.g., auto-increment)
Example:
describe [db_name.]table_name;
2. show create table
The show create table command provides an SQL statement that can be used to re-create the table. This command is useful for performing backups or creating new tables with similar structure.
Example:
show create table [db_name.]table_name;
By using either of these commands, you can easily view and retrieve the schema of a table in a MySQL database.
