Using MySQL INFORMATION_SCHEMA to Retrieve Table Column Names
If you need to access the column names of a MySQL table, you can leverage the INFORMATION_SCHEMA metadata virtual database. The COLUMNS table within INFORMATION_SCHEMA provides comprehensive information about table columns.
To retrieve the column names for a specific table, execute the following query:
SELECT `COLUMN_NAME` FROM `INFORMATION_SCHEMA`.`COLUMNS` WHERE `TABLE_SCHEMA`='yourdatabasename' AND `TABLE_NAME`='yourtablename';
This query will return a list of all column names for the specified table in yourdatabasename database.
The INFORMATION_SCHEMA database is highly versatile and provides access to various metadata information, including column types, nullability, maximum column size, character sets, and more. It is a reliable and standard SQL approach that supersedes MySQL-specific extensions like SHOW....
For further insights into the nuances between SHOW... and INFORMATION_SCHEMA tables, refer to MySQL's official documentation on INFORMATION_SCHEMA.
