Get All Column Names from a Table in SQL Server, MySQL, and Oracle Methods and Best Practices

To get the column names from a table in SQL Server, MySQL, and Oracle, you can use the following commands:

SQL Server:

SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'your_table_name'

MySQL:

SHOW COLUMNS FROM your_table_name;

Oracle:

SELECT COLUMN_NAME 
FROM ALL_TAB_COLUMNS 
WHERE TABLE_NAME = 'your_table_name'

Note that in all three cases, you will need to replace “your_table_name” with the actual name of the table you are querying.
