One table, waterchem, with primary key 'site' has columns easting and
northing with no values in them. A second table, sites, with primary key
'name' has values for easting and northing for each row. I want to update
waterchem with the easting and northing values from sites. My proposed
statement is,
UPDATE waterchem
SET waterchem.easting, waterchem.northing = sites.easting, sites.northing
FROM sites AS s
WHERE waterchem.site = s.name;
Is this correct? If not, what approach should I adopt?
No it's not quite correct:
UPDATE waterchem
SET waterchem.easting = s.easting
waterchem.northing = s.northing
FROM sites AS s
WHERE waterchem.site = s.name;
