Luamongo 是 MongoDB 的 Lua 驱动程序。
示例代码:
require('mongo')
-- Create a connection object
local db = assert(mongo.Connection.New())
-- connect to the server on localhost
assert(db:connect('localhost'))
-- insert a value into the namespace 'test.values'
assert(db:insert('test.values', {a = 10, b = 'str1'}))
-- the same using a JSON string
assert(db:insert('test.values', "{'a': 20, 'b': 'str2'}"))
-- insert a multiple values into the namespace 'test.values'
assert(db:insert_batch('test.values', {{a = 10, b = 'str1'}, {c = 11, d = 'str2'}}))
-- print the number of rows in the namespace 'test.values'
print(db:count('test.values'))
-- query all the values in the namespace 'test.values'
local q = assert(db:query('test.values', {}))
-- loop through the result set
for result in q:results() do
print(result.a)
print(result.b)
end
