Question

I have a MySQL table which has a product_id field (big integer)

1102330008
1102330025
1102330070
1103010009
1103010010
1103020006
…

I want to select rows which have product_id = 110301****. I tried to use this query:

SELECT * FROM `product` WHERE (product_id/10000)=110301  

but it does not return any values with this message:

MySQL returned an empty result set (i.e. zero rows). ( Query took 0.0005 sec )

Answer 1

MySQL documentation says that LIKE also uses indexes so I think you could also use:

SELECT *
FROM `product`
WHERE product_id LIKE '110301____' -- four undersores as biziclop suggested

edit: to fix your own query you would need to use FLOOR() (documentation) because it results something like:

1103010006 / 10000

which results 110301,0006 and it’s not equal to 110301
