Getting MySQL Column Names into an Array Using a Query

Question:

How can I retrieve all column names from a MySQL table into an array in PHP using a query?

Answer:

The most effective way to accomplish this is by utilizing the INFORMATION_SCHEMA metadata virtual database. Specifically, the INFORMATION_SCHEMA.COLUMNS table provides detailed information about table columns.

Query:

SELECT `COLUMN_NAME` 
FROM `INFORMATION_SCHEMA`.`COLUMNS` 
WHERE `TABLE_SCHEMA`='yourdatabasename' 
    AND `TABLE_NAME`='yourtablename';

This query retrieves the column names of the specified table from the information_schema database.

Advantages of Using INFORMATION_SCHEMA:

• Provides a standardized SQL approach across different database systems.
• Delivers ample information about columns, including type, nullability, size, and character set.
• Eliminates the need for manual text parsing.
• Offers a robust and versatile way to access metadata about your tables.

For further exploration, refer to the MySQL documentation on INFORMATION_SCHEMA for a comprehensive understanding of its capabilities.
