How to Efficiently Retrieve Column Names for All Tables in MySQL?

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>
Copy after login

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.
