I have got two Tables as shown above
The area column is common for both the tables .
From User Interface area and phone_number will be passed .
How to write a query to display the data from both the tables based on phone_number and area ??
I tried this way but i am not sure and its giving error
select c.phone_number
from customer_delivery_loc c
where c.area in (select locality , address , area from vendor_home_delivery )
where c.phone_number = '9848032919';
- MySQL Database Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'where c.phone_number = '9848032919'' at line 1

Answer 1

You need
and c.phone_number
in place of
where c.phone_number
in your query.

Answer 2

As one mistake pointed by already by #Ollie Jones for another error Operand should contain 1 column(s) error you can rewrite your query by using join
select c.phone_number
from customer_delivery_loc c
join vendor_home_delivery v
on(c.area = v.locality or c.area=v.address or c.area=v.area)
where c.phone_number = '9848032919';
Cause of this error is because you are comparing single column area with 3 columns using in()
