MySQL Full-Text Search with JOIN and Solution

Using Full-Text Search with a JOIN Query

Write a MySQL query to perform a full-text search for "blockchain" in the "Content" column of the Articles table and join with the Authors table to retrieve author details.

Solution:

-- Perform a full-text search for the term 'blockchain' in the Content column of the Articles table.
-- Join the Articles table with the Authors table to retrieve additional author details.
SELECT A.*, AU.AuthorName
-- Select all columns from the Articles table (aliased as A) and the AuthorName column from the Authors table (aliased as AU).
FROM Articles A
-- Use an INNER JOIN to combine the Articles table (A) with the Authors table (AU) based on the matching AuthorID column.
JOIN Authors AU ON A.AuthorID = AU.AuthorID
-- Filter the results to include only rows where the Content column matches the full-text search term 'blockchain'.
WHERE MATCH(A.Content) AGAINST('blockchain');

Explanation:

• Purpose of the Query:
• To retrieve articles about "blockchain" along with the corresponding author information.
• Demonstrates combining full-text search with JOIN operations.
• Key Components:
• JOIN Authors ON A.AuthorID = AU.AuthorID : Links articles with their authors.
• MATCH(A.Content) AGAINST('blockchain') : Filters articles using full-text search.
• Real-World Application:
• Enhances content platforms by integrating search with related metadata.

Notes:

• Ensure both tables have appropriate indexes for JOIN and full-text search operations.
• JOINs may affect performance; optimize queries accordingly.
