PHP Fetch data with two different function - php

Question

I have a question for this, maybe I am doing the wrong way
as I have created a two different search function which they have own different function search
as one is SKU and one is Date
I have created a code for MySQL and Workbench and it working fine as I'm using
SELECT
settlement_id, sku
FROM
settlements
WHERE
sku LIKE 'ISCE%'
AND settlement_id LIKE '7072432852'
GROUP BY sku
HAVING sku IS NOT NULL AND LENGTH(sku) > 0
ORDER BY sku
and it displayed fine
I use this same function for the PHP pages
$output = '';
if (isset($_POST["query"])) {
$search = mysqli_real_escape_string($conn, $_POST["query"]);
$queryskulist = "
SELECT
settlement_id,
sku,
FROM settlements
WHERE sku LIKE '%" . $search . "%' and settlement_id LIKE '%" . $search . "%'
GROUP BY sku
HAVING sku IS NOT NULL AND LENGTH(sku) > 0
ORDER BY sku
";
} else {
$queryskulist = "
SELECT
settlement_id,
sku,
FROM settlements
GROUP BY sku
HAVING sku IS NOT NULL AND LENGTH(sku) > 0
ORDER BY sku ";
}
as you can see
WHERE sku LIKE '%" . $search . "%' and settlement_id LIKE '%" . $search . "%'
that's where I am getting an error as I am able to get data from only one function like this
WHERE sku LIKE '%" . $search . "%'
but I am unable to get two different search result, should I use two different query $_POST["query"]?
Any advice would be great, or Sample/Example demo PHP site would be great, it would help me a big picture on it.

Answer 1

You can fix this by using the following
SELECT
settlement_id,
sku
FROM
settlements
WHERE
(CONCAT(sku, settlement_id) LIKE '%" . $search . "%')
AND
sku IS NOT NULL AND LENGTH(sku) > 0
ORDER BY
sku
Alternatively you should be able to wrap in parenthesis
WHERE (sku LIKE '%" . $search . "%') OR (settlement_id LIKE '%" . $search . "%')

Answer 2

do the fact you have not aggregation function you should use where
SELECT
settlement_id
, sku
FROM settlements
WHERE sku LIKE 'ISCE%'
AND settlement_id LIKE '7072432852'
WHERE sku IS NOT NULL AND LENGTH(sku) > 0
ORDER BY sku
the use of group by without aggreagtion function is deprecated in SQL .. and in the most recent version of mysql is not allowed .. (by default)
using group by without aggregation function you could obtain unpredictable result

Answer 3

Thank for the update, I have fixed this issue as I have decided to remove 'Sku' and keep the rest of it, so here is what happened.
'Settlement_id' is used an options dropdown value on the PHP pages which they are pulling data from MySQL and the 'SKU' search box are using on the input box. and the input box is using Javascript Ajax Filters to get data which it displayed result from 'Settlement_Id' data
here is a demo
