Big Csv import problem

cirollo · Jan 31, 2012

HI! I've a csv files of approx 37000 rows
I try to import in my SQL Table with this:

B4X:

   ' Creo la tabella Clienti
   Dim m As Map
   m.Initialize
   m.Put("IdCli", DBUtils.DB_TEXT)
   m.Put("Ragsoc", DBUtils.DB_TEXT)
   m.Put("Indirizzo", DBUtils.DB_TEXT)
   m.Put("Cap", DBUtils.DB_TEXT)
   m.Put("Localita", DBUtils.DB_TEXT)
   m.Put("Prov", DBUtils.DB_TEXT)
   m.Put("Telefono", DBUtils.DB_TEXT)
   m.Put("Mobile", DBUtils.DB_TEXT)
   m.Put("Iniziale", DBUtils.DB_TEXT)
   m.Put("Giorno", DBUtils.DB_TEXT)
   m.Put("Status", DBUtils.DB_TEXT)
   m.Put("Listino", DBUtils.DB_TEXT)
   m.Put("CatScm", DBUtils.DB_TEXT)
   m.Put("AliIva", DBUtils.DB_TEXT)
   DBUtils.CreateTable(SQL1, "Clienti", m, "IdCli")
   ' popolo la tabella clienti
   TxtLog.Text = "Inserimento Dati Tabella Clienti..." &Chr(10)&TxtLog.Text
   Dim su As StringUtils
   Dim Table As List
   Table = su.LoadCSV(sdRoot, "clienti.csv", ";")
   Dim Table2 As List
   Dim Items() As String
   Table2.Initialize
   For i = 0 To Table.Size - 1
      Items = Table.Get(i)
      Dim m As Map
      m.Initialize
      m.Put("IdCli", Items(0)) 
      m.Put("Ragsoc", Items(1))
      m.Put("Indirizzo", Items(2))
      m.Put("Cap", Items(3))
      m.Put("Localita", Items(4))
      m.Put("Prov", Items(5))
      m.Put("Telefono", Items(6))
      m.Put("Mobile", Items(7))
      m.Put("Iniziale", Items(1).SubString2(0,1))
      m.Put("Giorno", Items(8))
      m.Put("Status", Items(9))
      m.Put("Listino", Items(10))
      m.Put("CatScm", Items(11))
      m.Put("AliIva", Items(12))
      LblStatus.Text = Items(0)
      Table2.Add(m)
   Next
   DBUtils.InsertMaps(SQL1, "Clienti", Table2)
   Progressbar1.Progress = 50
   LblStatus.Text = Progressbar1.Progress &"%"

but after some seconds the tablet screen becomes all black and starting to vibrate.
After that forced closure is invoked

If I use a smaller file It doesn't happen. The db is on the sd card.
This is the complete code, You can notice that there are several tables that should be filled (each one with its own file csv)

does it end to fill one table before going to the next one?

What error message do you get in the Logs?
Only that can tell what the real problem is.

cirollo · Jan 31, 2012

how can I check the logs?

where I can find them?

thedesolatesoul · Jan 31, 2012

Are you running with B4a-Bridge?
On the IDE, on the right hand there is a Logs tab. Press Connect on there.
If you find nothing, its worth checking unfiltered logs too.

This is my log

as I expected the problem is on table Articoli, too much records?

Yes, you are out of memory.
Do you need to load everything into memory?
What are you trying to do?

insert record into a table

I need to insert records in a SQL table reading from a csv file

do you know another method to do that???

let me know....

thanks for the help

cirollo

thedesolatesoul · Jan 31, 2012

How big is the CSV file?

The easier way will be to break it into parts and import each part separately.

It does look like its more to do with a library rather than your code. Are you downloading by FTP?

Erel · Feb 1, 2012

It does look like its more to do with a library rather than your code.

In most cases libraries are not faster or more efficient than B4A code.

It is a bit hard to say, but the error seems to be with txtLog. How large is its text?

Why don't you use Log command instead.

cirollo · Feb 1, 2012

the file is...

Approx 4mb
i download it with ftp
but seems downloaded correctly
according to you what could be the limit of each part the file should be splitted?
after this there are other smaller files do i have the same problem?
Is possible to free some memory after each file import?

@erel what do you mean?

Erel · Feb 1, 2012

I think that the error is related to txtLog which gets longer all the time.

cirollo · Feb 1, 2012

no

Cause if i try with smaller file it works

Erel · Feb 1, 2012

If you like you can upload your project and I will check it.

cirollo · Feb 1, 2012

ok, but

the project is too big for upload on the forum, if you can give me an email I'll attach the zip file to it.

and also the files to be imported, even If there are on my ftp

Erel · Feb 1, 2012

You can send it to: erel@basic4ppc.com

cirollo · Feb 3, 2012

ok....

Erel but before sending to You I would like to make another test:

if I split the csv in more files, each one approx 1/10 of the original, can I solve the out of memory problerm or the memory will fill itself again processing the files....

in other words...does the memory free itself after one file processing before passing to the next one???

Erel · Feb 5, 2012

Memory is freed from objects that are no longer referenced.

cirollo · Feb 5, 2012

I need help!

because I'm going crazy about this problem:

I've splitted the big 37000 records csv file in more smaller files of 3000 records each.
The download phase has no problem, but when I try to insert the records inside the sql tables this is my log

this is the code, I cannot see any difference between, for example, the insert of "clienti" and that of "parape" or "articoli"

INSERT INTO [Parape] () VALUES ()

Aren't the columns missing?

cirollo · Feb 6, 2012

are you talking about the csv file?

The file has 3 records (3 rows) each field separated by ";"

all the csv files that I'm using don't have first row with field names.

Could it be because I'm using the same variables for all the imports:

B4X:

 Dim su As StringUtils
    Dim Table,Table2 As List
    Dim Items() As String
.......
  Table = su.LoadCSV(sdRoot, "clienti.csv", ";")
    Table2.Initialize
    For i = 0 To Table.Size - 1
        Items = Table.Get(i)
        Dim m As Map
        m.Initialize

how does it works? it ends the insert of a file before going to the next one?
if parape fail to insert records, why also the others fail? it seems that only smaller files will work!

Big Csv import problem
