Possibile elaborare sequenzialmente records

11 posts in this topic

Il problema e' come leggere sequenzialmente i records di gruppi di record estratti da una tabella o di una intera tabella.

In altri linguaggi ci sono istruzioni del tipo Next, previuos, MoveNext...Movelast, ..., go top, go record etcetera

Qualcuno mi da' una dritta ?

In other languages there are instructions on the type Next, previuos, MoveNext MoveLast ..., ..., go top, go record etcetera

Ho una tabella con 20000 records.

Ciascun record contiene 20 campi.

Devo rielaborare solo alcuni campi.

Come leggere tutti i records della tabella, uno per volta, dal primo all'ultimo ?

Grazie

I have a table with 20,000 records.

Each record contains 20 fields.

I have to rework a few fields.

How to read all the records of the table, one by one, from first to last?

Thanks

No probabilmente non ha letto con attenzione la dimensioni della tabella

Ad ogni modo in che linguaggio e' ?

[...] ... btw what language is the table written in ?

_SQLite_FetchData retrieves one row at a time. To segment your query you can use LIMIT 0,20

#include <SQLite.au3>
#include <SQLite.dll.au3>

Local $hQuery, $aRow, $aNames
_SQLite_Startup ()
_SQLite_Open  () ; open  :memory: Database
_SQLite_Exec  (-1, "CREATE TABLE aTest  (a,b,c);")
_SQLite_Exec (-1,  "INSERT INTO aTest(a,b,c) VALUES  ('c','2','World');")
_SQLite_Exec (-1,  "INSERT INTO aTest(a,b,c) VALUES ('b','3','  ');")
_SQLite_Exec (-1, "INSERT INTO aTest(a,b,c)  VALUES ('a','1','Hello');")
_SQlite_Query (-1,  "SELECT ROWID,* FROM aTest ORDER BY a;", $hQuery)
_SQLite_FetchNames  ($hQuery, $aNames)
ConsoleWrite(StringFormat(" %-10s  %-10s  %-10s  %-10s ", $aNames[0], $aNames[1], $aNames[2],  $aNames[3]) & @CR)
While _SQLite_FetchData ($hQuery, $aRow) = $SQLITE_OK ; Read Out the  next Row
    ConsoleWrite(StringFormat(" %-10s  %-10s   %-10s  %-10s ", $aRow[0], $aRow[1],  $aRow[2], $aRow[3]) & @CR)
WEnd
_SQLite_Exec  (-1, "DROP TABLE  aTest;")
_SQLite_Close ()
_SQLite_Shutdown  ()

Thanks weaponx

_SQLite_FetchData (retrieves one row at a time) is OK !!!

Grazie weaponx

_SQLite_FetchData (elabora una riga per volta) e' la soluzione.

Excuse me

The solution, for me is:

;

; LetturaSequenzialeRecords.au3

; Esempio di elaborazione sequenziale dei records di una tabella SQLite3 con autoit3

; legge solo alcuni record (qui dal 3° al 7°)

; $nLeggoDa e $nLeggoFinoA determinano quali record leggere

;

;

#include <SQLite.au3>

#include <SQLite.dll.au3>

Local $hQuery, $aNames, $aRow

$sDbFile = "atti.db"

_SQLite_Startup()

_SQLite_Open($sDbFile)

_SQlite_Query (-1, "SELECT ROWID,* FROM TblImport;", $hQuery)

;

; Show Table (using SQLite3.dll)

_SQLite_FetchNames ($hQuery, $aNames) ; Read out Column Names

;

$nConta = 0 ; records counter

$nLeggoDa = 3 ; start reading

$nLeggoFinoA =7 ; stop reading

While 1 ; start loop for reading records

$nConta += 1

IF _SQLite_FetchData ($hQuery, $aRow) = $SQLITE_OK THEN ; record OK

IF $nConta = 1 Then ; display field header only first record

ConsoleWrite($aNames[0] & " " & $aNames[1] & " " & $aNames[2] & " " & $aNames[3] & " " & $aNames[4] & " " & $aNames[5] & " " & @CR)

Endif

IF $nConta >= $nLeggoDa and $nConta <= $nLeggoFinoA THEN

; Here Your Instructions (QUI LE ISTRUZIONI PER ELABORARE CIASCUN RECORD)

; example (esempio)

ConsoleWrite($aRow[0] & " " & $aRow[1] & " " & $aRow[2] & " " & $aRow[3] & " " & $aRow[4] & " " & $aRow[5] & " " & @CR)

;

endif

Else

ExitLoop

endif

WEnd

_SQLite_Close ()

_SQLite_Shutdown ()

;~ Output:

; rowid Column_1 Column_2 Column_3 Column_4 Column_5

; 3 1996 001 DI 810 139,43

; 4 1997 001 DI 93 144,59

; 5 1997 001 DI 94 144,59

; 6 1997 001 DI 1003 322,20

; 7 1997 003 DI 295 263,38
