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;
---------------------------------------------------------------------------------------
res = conn:execute("SELECT last_insert_rowid()")
display(res:fetch())
results:close()
----------------------------------------------------------------------------------------
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 (connection, sql_statement)
local cursor = assert (connection:execute (sql_statement))
return function ()
return cursor:fetch()
end
end
for id,city,name in rows (conn, [[select id,city,name from mySheet WHERE id > 1 AND id < 5]]) do
print (name, city, id)
end
