Syntax error SQL

[roaddog]

function setTurfOwners() 
    local realTable = sortTable() 
    for i, v in ipairs(realTable) do 
        local r, g, b = exports.AGGroups:getGroupColor ( v[3]) 
        local rE = radar[v[1]] 
        local turfColor = toJSON({r, g, b}) 
        if (rE) then 
            setRadarAreaColor(rE, r, g, b, 200) 
        end 
        if (t_owner[v[1]]) then 
            dbExec(db, "UPDATE theturfs SET owner=?, color=? WHERE name=?", tostring(v[3]), tostring(fromJSON(turfColor)), tostring(v[1])) 
            break 
        else 
            dbExec(db, "INSERT INTO theturfs SET VALUES (?, ?, ?)", tostring(v[1]), tostring(v[3]), tostring(turfColor)) -- Error 
            t_owner[v[1]] = v[3] 
            break 
        end 
        t_owner[v[1]] = v[3] 
    end 
end  

I have got an error at line 14

debug says syntax error near SET (1) something I forgot to take a screen.

Thanks in advance
