Dynamic SQL query to get single value from list in a column

Question

I have two tables: tblWorkers and tblSkills. tblWorkers has a
column, Skills, which is populated from a multiple-checkbox form
field with one or more skill_IDs from tblSkills, so each
tblWorkers.Skills consists of a list of one or more comma-delimited
values. For any Skill_ID, I need to generate a listing of all
Workers with the corresponding skill, so I have tried to do
something along the lines of SELECT WorkerName FROM tblWorkers
WHERE Skills IN (Skills, #FORM.Skill_ID#) ... or WHERE Skills IN
(ListFind(Skills, #FORM.Skill_ID#)) ... etc. ??? My results (once I
got data type mismatches out of the way) return all Workers, not
just those with the desired Skill. There must be an easy way to do
this ... How do people with a bit more CF/SQL experience than I
have do this???

As Kronin implied, we normalize our databases. If you don't
understand that answer, the book "Database Design for Mere Mortals"
is often mentioned on this forum.
