Select from Describe SQL

As a programmer, you may encounter the need to describe a table in SQL. The SELECT FROM DESCRIBE statement allows you to retrieve the column names and their datatypes for a specified table. This information can be useful when developing queries or applications that query the database.

Syntax

SELECT column_name, data_type
FROM information_schema.columns
WHERE table_name = 'your_table_name';

• column_name: The name of the column in the specified table.
• data_type: The datatype of the column.

Example

Suppose you have a table named employees. You can use the SELECT FROM DESCRIBE statement to retrieve information about the columns in the table.

SELECT column_name, data_type
FROM information_schema.columns
WHERE table_name = 'employees';

| Column Name | Data Type | |-------------|-----------| | id | INT | | first_name | VARCHAR | | last_name | VARCHAR | | email | VARCHAR | | phone | VARCHAR | | hire_date | DATE | | job_title | VARCHAR | | salary | INT |

Conclusion

In summary, the SELECT FROM DESCRIBE statement can be used to retrieve information about the columns in a specified table. This can be useful when developing queries or applications that query the database.
