So i don't forget again. This is how you sent raw sql to the db and fetch the result
mydb = db:create("mydb",
{
mySheet = {
name = "", id = 0, city = "",
_index = { "name" },
_unique = { "id" },
_violations = "FAIL"
}
})
myData = {
{name="Ixokai", city="Magnagora", id=1},
{name="Vadi", city="New Celest", id=2},
{name="Heiko", city="Hallifax", id=3},
{name="Keneanung", city="Hashan", id=4},
{name="Carmain", city="Mhaldor", id=5},
{name="Ixokai", city="Hallifax", id=6},
}
db:add(mydb.mySheet, unpack(myData))
local conn = db.__conn.mydb;
---------------------------------------------------------------------------------------
display(conn:getlastautoid())
----------------------------------------------------------------------------------------
results = conn:execute[[
SELECT city,name FROM mySheet WHERE city = 'Hallifax'
]]
local city,name = results:fetch()
while city do
print(city,name)
city,name = results:fetch()
end
results:close()
----------------------------------------------------------------------------------------
results = conn:execute[[
SELECT * FROM mySheet WHERE name = 'Ixokai'
]]
local res = results:fetch({}, "a")
while res do
print(res.id, res.city, res.name)
res = results:fetch(res, "a")
end
results:close()
----------------------------------------------------------------------------------------
function rows(conn, query)
local cursor = assert(conn:execute(query))
local res = {}
return function ()
return cursor:fetch(res, "a")
end
end
local query = [[
select * from mySheet WHERE id > 1 AND id < 5
]]
for row in rows(conn, query) do
print(row.name, row.city, row.id)
end
----------------------------------------------------------------------------------------
function urows(conn, query)
local cursor = assert(conn:execute(query))
return function ()
return cursor:fetch()
end
end
local query = [[
select name,city,id from mySheet WHERE id > 1 AND id < 5
]]
for name,city,id in urows(conn, query) do
print(name, city, id)
end
