Do you want sql? You can use update
and exists
as follows:
Update employees
Set dept_name = 'dept3'
Where exists (select 1 from New_depts_employees_id n where n.emp_id = employees.emp_id)
Open new query constructor.
Add both tables to it.
Drag Employees.empid
and drop it onto New_depts_employees_id.empid
- a link occures. Not needed if the link is created automatically.
Change query type to UPDATE.
Set "Column to update" to Employees.deptname
.
Set "Value to set" to 'dept3'
.
Click "Execute".
You may save this query and convert static 'dept3'
value to query parameter for future use from external application. Or you may open query constructor in SQL Mode and copy query text from it for external use.
