好吧，我承认我问得有点傻。
我用下面方法实现的。
local query = "select qymc as suggestions from SFGL_QY where qymc like " .. xiaoqu
res, err, errno, sqlstate = db:query(query)
if not res then
ngx.say("bad result: ", err, ": ", errno, ": ", sqlstate, ".")
return
end
local result={}
for i, row in ipairs(res) do
result[i] = res[i].suggestions
end
result = {query=
args.name,suggestions=result}
local cjson = require "cjson"
ngx.say(cjson.encode(result))
输出：
{"query":"明","suggestions":["光明一小区","光明二小区","文明一小区","文明二小区","新明苑小区","河明小区","通明苑小区"]}
