the format looks ok but perhaps you mean to group all the ors together with the last and. In that case put an open parentheses after the key word AND and a close parentheses at the end of the last or condition

1. Based on your requirement use parenthesis between and & or conditions

2. cust_key is not to be used multiple times it can be used like below

WHERE d.customer flag = 0
AND d.customer_type = 'Individual'
AND ( (c.cust_key in (select custkey from employee where Location IN (''italy',germany')
union Select abc.custkey from vw_test Where delete_flag = 0
union Select custkey from vw_client_location where email not in (select email from vw_expired )

or emp_country in (select country from Lookup_countries)
)
