How to search multiple columns in MySQL?
If it is just for searching then you may be able to use CONCATENATE_WS.This would allow wild card searching.There may be performance issues depending on the size of the table.
SELECT * FROM pages WHERE CONCAT_WS('', column1, column2, column3) LIKE '%keyword%'
You can use the AND or OR operators, depending on what you want the search to return.
SELECT title FROM pages WHERE my_col LIKE %$param1% AND another_col LIKE %$param2%;Both clauses have to match for a record to be returned. Alternatively:
SELECT title FROM pages WHERE my_col LIKE %$param1% OR another_col LIKE %$param2%;If either clause matches then the record will be returned.
For more about what you can do with MySQL SELECT queries, try the documentation.
If your table is MyISAM:
SELECT *FROM pagesWHERE MATCH(title, content) AGAINST ('keyword' IN BOOLEAN MODE)This will be much faster if you create a FULLTEXT index on your columns:
CREATE FULLTEXT INDEX fx_pages_title_content ON pages (title, content), but will work even without the index.
