Requisite snarky comment: if a join depends on only _part_ of the value of another field, the data is not normalized.
Are the DeptNum fields really literally question marks and digits, as if they were wildcards? If so, you could write some UDF to convert DOS wildcards of * and? to SQL wildcards of % and _ It's a bit unholy but it ought to get the job done: SELECT Employee.*, Dept.* from Employee JOIN Dept ON Employee.Dept LIKE MyUDF(Dept.DeptNum) On Tue, Jul 2, 2019 at 12:57 PM Paul H.
