Select from one layer by field values in another layer?

[TroyKechely]

Is it possible to select all the features of a point layer based on the values in the field of another layer?  I know how to do it with a few using the select by attributes but my problem is the unique values I need to use number over 200.  The main layer has over 1 million points and the other layer is a small subset of that picked by polygon. I need to select all the points in the main layer that have the same field values as the selected layer data.  I hope that makes sense.

Thanks.

Troy,

If there is a common attribute between the two then you can a join.  If the data is spatially contained in another layer (such as a well within a parcel) then you can add a spatial join.  Both options can be found by right clicking on a layer and selecting the join and relate button.

I hope that helps!
