Connection utilities for lua-resty-mysql,support for read and write separation，support for instantiating different databases
syntax: yourdb = db:new(database)
if there is not a database name, database = "default"
local libmysql = require("libmysql")
local db_member = libmysql:new("member")
local db_test = libmysql:new()
syntax: res, err = yourdb:query("select des from test1 where test_id=? ", {3})
Some read database operations
syntax: res, err = yourdb:main("UPDATE test1 SET des='my lua' WHERE test_id=?", {3})
Some write database operations
local libmysql = require("libmysql")
local db_member = libmysql:new("member")
local db_test = libmysql:new()
local res, err = db_member:query("select des from test1 where (test_id=? )", {3})
if err or not res or type(res)~="table" or #res<1 then
ngx.say("test database member query :nothing")
else
ngx.say("test database member query :res")
end
local res, err = db_test:query("select des from test1 where test_id=? ;", {3})
if err or not res or type(res)~="table" or #res<1 then
ngx.say("test database test query :nothing")
else

end
local res, err = db_test:main("UPDATE test1 SET des='my lua' WHERE test_id=?", {3})
