Efficiently Retrieving Column Names for All Tables in MySQL

Retrieving all column names across all tables in MySQL can be a time-consuming task, but there is a swift solution to bypass listing each table individually.

Solution:

Utilizing the information_schema.columns table, you can effortlessly access column names for all tables within your database. The following SQL query accomplishes this:

<code class="sql">select column_name
from information_schema.columns
where table_schema = 'your_db'
order by table_name,ordinal_position</code>

By replacing 'your_db' with the desired database name, this query will retrieve all column names, ordered by table name and column position.

Additional Notes:

• The table_schema filter limits the results to tables within the specified database.
• The ordinal_position ordering ensures that columns are returned in the same order as they appear in the tables.
