I need to 'extract' a list of variables based on the IDs from another table. Using a subquery seems to be the best method. I have a large list of variables and have outside calculated a second list. This second list does not have coordinate data attached to it, so I need to select the same values in the original list to pull the data out. The shapefile and table are both in the catalog.
I try to do a simple select by attribute. It gives me the
SELECT * FROM US_Maize_All WHERE: "pointid" = (SELECT "pointid" FROM Maize_Table)
but this only gives me a SQL expression error. The "pointid" parameters are selected from the option box. As far as I can tell this is the exact format as any other info I can find online. Has to be something I'm overlooking why this will not work.
