Split a string on sqlite - string

Question

i don't know sqlite but I have to implement a database already done. I'm programming with Corona SDK. The problem: i have a column called "answers" in this format: House,40|Bed,20|Mirror,10 ecc.
I want to split the string and remove "," "|" like this:
VARIABLE A=House
VARIABLE A1=40
VARIABLE B=Bed
VARIABLE B1=20
VARIABLE C=Mirror
VARIABLE C1=10
I'm sorry for my english. Thanks to everybody.

Try this:
If you want to simply remove the characters, then you can use the following:
Update 3 :
local myString = "House;home;flat,40|Bed;bunk,20|Mirror,10"
local myTable = {}
local tempTable = {}
local count_1 = 0
for word in string.gmatch(myString, "([^,|]+)") do
myTable[#myTable+1]=word
count_1=count_1+1
tempTable[count_1] = {} -- Multi Dimensional Array
local count_2 = 0
for word_ in string.gmatch(myTable[#myTable], "([^,|,;]+)") do
count_2=count_2+1
local str_ = word_
tempTable[count_1][count_2] = str_
--print(count_1.."|"..count_2.."|"..str_)
end
end
print("------------------------")
local myTable = {} -- Resetting my table, just for using it again :)
for i=1,count_1 do
for j=1,#tempTable[i] do
print("tempTable["..i.."]["..j.."] = "..tempTable[i][j])
if(j==1)then myTable[i] = tempTable[i][j] end
end
end
print("------------------------")
for i=1,#myTable do
print("myTable["..i.."] = "..myTable[i])
end
--[[ So now you will have a multidimensional array tempTable with
elements as:
tempTable = {{House,home,flat},
{40},
{Bed,bunk},
{20},
{Mirror},
{10}}
So you can simply take any random/desired value from each.
I am taking any of the 3 from the string "House,home,flat" and
assigning it to var1 below:
--]]
var1 = tempTable[1][math.random(3)]
print("var1 ="..var1)
-- So, as per your need, you can check var1 as:
for i=1,#tempTable[1] do -- #tempTable[1] means the count of array 'tempTable[1]'
if(var1==tempTable[1][i])then
print("Ok")
break;
end
end
----------------------------------------------------------------
-- Here you can print myTable(if needed) --
----------------------------------------------------------------
for i=1,#myTable do
print("myTable["..i.."]="..myTable[i])
end
--[[ The output is as follows:
myTable[1]=House
myTable[2]=40
myTable[3]=Bed
myTable[4]=20
myTable[5]=Mirror
myTable[6]=10
Is it is what you are looking for..?
