Access Select query producing duplicate records

running access 2k10, query which is producing multiple duplicate records in the result. Not on all records, just some. I've checked all related tables and there are no duplicates. I've added "Distinct" to the query but no change.

I've attached an rtf doc with the access query and the sql view. Any help greatly appreciated.

Try linking the Job table to the Tasks table by Job_No, instead of from JobRS to Tasks.

No difference, linking as . I believe it has something to do with Tasks. If I remove them from the query completely, I don't get the dups

Please indicate what you mean by "producing multiple duplicate records in the result", because DISTINCT will never give you duplicates.  It is impossible for this to happen.

if u look at the sql in the attachment above, I inserted distinct after SELECT in the vba sql statement.

For a few entries, not all, i will get 2 to 4 exact duplicate records for a given acronym.

jsgould, I am sorry to be a pain here, but that is simply not possible.  There has to be some difference in the records.

it is my belief that some believe 'distinct' holds a magic quality and that it will intuitively know that the user wants only "one of something" and the other parts of a row "will just happen" (i.e. the magic occurs here).

select distinct -- is not magic
all, columns, will, be, evaluated, and, this, row, is, different, to, the, next, one, by, any, change
from real_world

the message is: "select distinct" works across everything in the row, the whole shooting match, the full enchilada, etc. Just the tiniest difference in any value will make a row "distinctive" from all other rows.

"multiple duplicate records" means you want something that select distinct cannot provide.

please provide your query, some results of it, and an explanation of what you consider is being duplicated. The solution almost certainly will not be "select distinct" by the way.

apologies in advance for the flippancy above - just trying to make a point through some humor
