but it returns nothing when the passed value is null and I do have null in the table!
here is my stored procedure:
JOIN assets$status ON `assets$status`.status_id = assets$audit.audit_status
LEFTJOIN assets$conditions ON `assets$conditions`.condition_id = assets$audit.audit_condition
WHERE item_id = param_item_id
AND location = param_loaction
AND floor = param_floor
AND room = param_room
AND department = param_department
AND employee = param_employee
ORDERBY audit_date DESC, created_date DESC;
Read and understand this visual explanation of sql joins[^] then you will have an idea of what is happening.
You may not have a null value in the table but you certainly have a left join which will return nulls if there is no corresponding row on the right side of the join.
