给出一个员工工资表,列 EmployeeID, Salary, 和 DepartmentID,写一个SQL查询,以找到每个部门的最低工资.
You can use the 'GROUP BY' clause and the 'MIN' function to find the minimum salary for each department. The query would be:

```
SELECT DepartmentID, MIN(Salary)
FROM EmployeeSalaries
GROUP BY DepartmentID;
```

This will group the salaries by DepartmentID, and return the minimum salary for each group.
