Hi, microdevweb.

Something wrong in your example:

Good luck!

Hi AAT,
I did not implement the database, you must do

Code: Select all

Procedure pCreateTable(DataBase)
      Protected query$,Result
      ;Table des civilités
      query$="CREATE TABLE IF NOT EXISTS TbCivilite ("+
             "id INTEGER PRIMARY KEY AUTOINCREMENT,"+
             "civilite TEXT)"
      Result=DatabaseUpdate(DataBase,query$)
      If Result=0
            MessageRequester("Erreur",DatabaseError())
            ProcedureReturn #False
      EndIf
      ;Table des Pays
      query$="CREATE TABLE IF NOT EXISTS TbPays ("+
             "id INTEGER PRIMARY KEY AUTOINCREMENT,"+
             "pays TEXT)"
      Result=DatabaseUpdate(DataBase,query$)
      If Result=0
            MessageRequester("Erreur",DatabaseError())
            ProcedureReturn #False
      EndIf
      ;Table des Pays
      query$="CREATE TABLE IF NOT EXISTS TbLocalite ("+
             "id INTEGER PRIMARY KEY AUTOINCREMENT,"+
             "idPays INT,"+
             "localite TEXT,"+
             "code_postal TEXT"+  
      ")"
      Result=DatabaseUpdate(DataBase,query$)
      If Result=0
            MessageRequester("Erreur",DatabaseError())
            ProcedureReturn #False
      EndIf
EndProcedure
;Création du fichier DataBase
Procedure pCreateDataBase()
      CreateDirectory(GetCurrentDirectory()+"\DB")
      DataBaseFile$=GetCurrentDirectory()+"\DB"+"\Animalia.sqlite"
      If FileSize(DataBaseFile$)=-1
            If CreateFile(0,DataBaseFile$)=0
                  MessageRequester("Erreur","La Data base n'a pas été créée...",#PB_MessageRequester_Ok)
                  ProcedureReturn #False  
            Else
                  CloseFile(0) 
            EndIf
      EndIf
      If OpenDatabase(0,DataBaseFile$,"","")=0
            MessageRequester("Erreur","Impossible d'ouvrir la base de données...",#PB_MessageRequester_Ok)
            ProcedureReturn #False
      EndIf
      pCreateTable(0)
      ProcedureReturn #True
EndProcedure

Hi, microdevweb

I understood you, thanks!
One more remark:
GetCurrentDirectory() - Returns the full path of the current directory. It will end with a directory separator ('\' on Windows and '/' otherwise). ((c) Help to PureBasic)
so "backslash" in
GetCurrentDirectory()+"\
is excess:

Code: Select all

debug GetCurrentDirectory()+"\DB" 
debug GetCurrentDirectory()+"\DB"+"\Animalia.sqlite"

Good luck!

Hi,

it works also with PostgreSQL if you modify your code a bit:

replace

Code: Select all

query$+" LIMIT "+Str(myTable()\firtLine-1)+","+myTable()\nbLineScreen

with

Code: Select all

query$ + " LIMIT " + myTable()\nbLineScreen + " OFFSET " + Str(myTable()\firtLine-1)

Than you can use:

Code: Select all

Global DataBase$="host=localhost dbname=test"

instead of

Code: Select all

Global DataBase$=GetCurrentDirectory()+"DB\Teste.sqlite"

Oh, I replaced DataFile$ wih DataBase$

It's not the fastest solution and for large databases it's not really usable, but it works

Thank you infratec for the info,

I was thinking of doing a version for protgres sql in the near future

I tested on the basis of records 100000. It had air fluid

Hi,

one thing I just noticed:

If you are nearly at the bottom of a table which is sorted after field1
and you enter a search text which should shows you entries from the mid of the table,
than you see an empty gadget after pressing return.
Very late I noticed that I have to scroll up by hand to see the entries.

The offset should be set to 0 if a search starts.
