If you type data in 1 table will it populate to another table?

    I have 2 tables linked in a relationship, is there any way if I type
    information into a field in 1 table that it will auto populate to the same
    field in the other table?
    Thanks

    The same field in another table? That would not be wise. The whole point
    of relational databases is to store data only once in one table, but create
    links so you can pull related information from other tables.

    No; but it is neither necessary nor desirable to do so. Creating an
    empty "placeholder" record accomplishes nothing (other than to create
    problems down the road when the record doesn't get filled in).

    Instead, use a Form based on the "one" table, with a Subform based on
    the "many" table for your data entry; use the linking field as the
    master/child link fields on the subform control. When you start to
    enter data in the Subform (but not before!), a new record will be
    created with the linking field.

Since you're here... we have a small favor to ask...

More people are visiting & reading SPN than ever but far fewer are paying to sustain it. Advertising revenues across the online media have fallen fast. So you can see why we need to ask for your help. Donating to SPN's is vote for free speech, for diversity of opinions, for the right of the people to stand up to religious bigotry. Without any affiliation to any organization, this constant struggle takes a lot of hard work to sustain as we entirely depend on the contributions of our esteemed writers/readers. We do it because we believe our perspective matters – because it might well be your perspective, too... Fund our efforts and together we can keep the world informed about the real Sikh Sikhi Sikhism. If everyone who writes or reads our content, who likes it, helps us to pay for it, our future would be much more secure. Every Contribution Matters, Contribute Generously!
