connecting to two different sqlite databases in lua using luasql - sqlite

Question

Goal
I'm trying to connect to two different databases, one after the other.
I know the first connection is working because I attempt to create a new record, and it works. When I try to connect to the second database and query a table, the logic fails with an error saying that the table I'm querying doesn't exist. But i know it does.
Here's the test code that creates the connection objects:
local database1con
local database2con
local database1env
local database2env
local firstdatabase_connect = function()
if not database1con then
database1env = assert (luasql.sqlite3())
database1con = assert (database1env:connect("database1.sqlite"))
return true
else
return false
end
end
local seconddatabase_connect = function()
if not database2con then
database2env = assert (luasql.sqlite3())
database2con = assert (database2env:connect("database2.sqlite"))
return true
else
return false
end
end
local firstdatabase_disconnect = function()
if database1env then
database1env:close()
database1env = nil
end
if database1con then
database1con:close()
database1con = nil
end
end
local seconddatabase_disconnect = function()
if database2env then
database2env:close()
database2env = nil
end
if database2con then
database2con:close()
database2con = nil
end
end
And here's the logic that tries to actually connect to the databases:
local connected = firstdatabase_connect()
-- run some select & insert commands
firstdatabase_disconnect()
-- now connect to second database
sql = "INSERT INTO users VALUES("..user_id..", "..username.value..", 'test',"..os.date("%Y%m%d%H%M%S")..", Null,Null)"
local db2connected = seconddatabase_connect()
if db2connected then
local res, err = database2con:execute(sql)
if not res and err then
success = false
end
seconddatabase_disconnect()
end
Problem
The insert fails with the following message: LuaSQL: no such table: users
The users tables doesn't exist in database1, but does exist in database2.
What i've tested so far
I thought that perhaps even though I'm disconnecting from the first database, it was somehow checking the wrong db. So after I make the call to firstdatabase_disconnect(), I added another select statement that attempted to select from the first database.
The system failed with a message that the connection object for database1 is nil.
which is good.
I'm not sure what else to test.
If you have any suggestions, I'd appreciate it.
