Simple MySQL select taking too much time

Question

I am having following simple query, but its taking too much time (.5 seconds/half of a second), I am unable to find the reason. I want to improve the performance of Search.

Title

VARCHAR (50), Collation = latin1_general_ci, NULL allowed, MySQL Engine: MyISAM

Number of record in Product table: 163129

CatID

Foreign Key (int) From Category table

I already have tried this Optimize statement

---

OPTIMIZE table Product

---

Here is the simple query.

---

SELECT COUNT(*)
FROM 
Product
WHERE 
CatID=123 
AND Title = 'abc xyz'

---

Please help. Thanks in advance.

Answer 1

Taking more time meaning the table is not properly indexed and probably doing full table scan.

For this particular query a covering index would be useful

alter table Product add index cat_title_idx(CatID,Title);

Make sure to take a backup of the table before applying the index.
