Hi, I believe the "tDate" is stored with milliseconds precision which could explain why these duplicate dates are shown.
Could you try running the following query: "SELECT userid, secondaryid, blobAsBigint(timestampAsBlob("tDate")), tid3, sid4, pid5, associate_degree FROM user_data;" The "tDate" column should be shown with different values at that point.
