Why are my records blank in my Access query?

问题

I'm trying to run this query:

SELECT tbl_G_ov_wta.PK_G, qry_performPrepElo_wta.PK_G, qry_performPrepElo_wta.ID1_ocStake
FROM tbl_G_ov_wta INNER JOIN qry_performPrepElo_wta ON tbl_G_ov_wta.PK_G = qry_performPrepElo_wta.PK_G

For some reason it won't pull through the values of qry_performPrepElo_wta.ID1_ocStake. Worth mentioning that PK_G is a common primary key. In playing around with this I've found that adding in criteria as follows fixes the issue:

SELECT tbl_G_ov_wta.PK_G, qry_performPrepElo_wta.PK_G, qry_performPrepElo_wta.ID1_ocStake
FROM tbl_G_ov_wta INNER JOIN qry_performPrepElo_wta ON tbl_G_ov_wta.PK_G = qry_performPrepElo_wta.PK_G
WHERE (((tbl_G_ov_wta.PK_G) Between 1 And 1000000));

Any ideas on why this might be?
