I’m trying to open an MS Access table, add new records to it, and then update those added records using the System.Data.Odbc method from IronPython. I know this is possible since I was able to do this with VBScript using the createobject("adodb.recordset") method. At this point I figure instead of creating a recordset with a Client cursor to open the table I would need to use a datareader or a dataset somehow.  So I just need assistance with the proper syntax to do the same using System.Data.Odbc from IronPython.
Here is what I have so far which deletes all existing records from the “tblBooks" table, and this works perfectly.  Now what I want to do it open that same table where I can add new records to it, and then update the table with those added records.

import clr, os, sys
from os import path
clr.AddReference('System.Data')
from System.Data.Odbc import OdbcCommand, OdbcConnection

strScriptDirectory = os.path.dirname(__file__)
strComicBaseFile = strScriptDirectory + \\ComicBase.mdb
strMdbDataSource = r'Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=' + strComicBaseFile
objConnMDBComicBase = OdbcConnection(strMdbDataSource)
objConnMDBComicBase.Open()
strSQL = "DELETE * FROM tblBooks"
objSQLCommand = OdbcCommand(strSQL, objConnMDBComicBase)
objSQLCommand.ExecuteNonQuery()

Open in new window


Thank you all for any assistance that you can provide.

You can use standard INSERT and UPDATE statments against Access as well, so you could just use the same basic syntax except with a valid SQL INSERT or UPDATE statement.

You can also open a Recordset, but unless you need to work with that recordset AFTER adding the new record, then there's really no reason to do this.

For example:

strSQL = "INSERT INTO tblBooks(BookName, BookAuthor) VALUES('My Pretty Pony', 'Stephen King')"

The nust build and run that Command object.

Thank you LSMConsulting!  That was enough to get me what I wanted!  I found it interesting that using this method of updating a MS Access database file doesn't require a separate UPDATE command.  Here is the code (so others can benefit from what I've learned) I able to produce after utilizing your comment.

[code]import clr, os, sys
from os import path
clr.AddReference('System.Data')
from System.Data.Odbc import OdbcCommand, OdbcConnection
global strScriptDirectory, strComicBaseFile, strMdbDataSource, objConnMDBComicBase, strSQL, objSQLCommand

strScriptDirectory = os.path.dirname(__file__)
strComicBaseFile = strScriptDirectory + \\ComicBase.mdb
strMdbDataSource = r'Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=' + strComicBaseFile
objConnMDBComicBase = OdbcConnection(strMdbDataSource)
objConnMDBComicBase.Open()
strSQL = "DELETE * FROM tblBooks"
objSQLCommand = OdbcCommand(strSQL, objConnMDBComicBase)
objSQLCommand.ExecuteNonQuery()

def UpdateComicBase2(books):
      for book in books:
            if book.ComicInfoIsDirty!="false":
                  strBookId = str(book.Id)
                  strSQLcolumns = "INSERT INTO tblBooks(\"Id\""
                  strSQLvalues = ") VALUES(\'" + strBookId + "\'"
                  strBookFile = str(book.FilePath)
                  strSQLcolumns = strSQLcolumns + ", \"File\""
                  strSQLvalues = strSQLvalues + ", \'" + strBookFile + "\'"
                  if book.Publisher != "":
                        strBookPublisher = str(book.Publisher)
                        strSQLcolumns = strSQLcolumns + ", \"Publisher\""
                        strSQLvalues = strSQLvalues + ", \'" + strBookPublisher + "\'"
                  if book.Series != "":
                        strBookSeries = str(book.Series)
                        strSQLcolumns = strSQLcolumns + ", \"Series\""
                        strSQLvalues = strSQLvalues + ", \'" + strBookSeries + "\'"
                  if book.Volume != -1:
                        strBookVolume = str(book.Volume)
                        strSQLcolumns = strSQLcolumns + ", \"Volume\""
                        strSQLvalues = strSQLvalues + ", \'" + strBookVolume + "\'"
                  if book.Format != "":
                        strBookFormat = str(book.Format)
                        strSQLcolumns = strSQLcolumns + ", \"Format\""
                        strSQLvalues = strSQLvalues + ", \'" + strBookFormat + "\'"
                  if book.Number != "":
                        strBookNumber = str(book.Number)
                        strSQLcolumns = strSQLcolumns + ", \"Number\""
                        strSQLvalues = strSQLvalues + ", \'" + strBookNumber + "\'"
                  if book.Tags != "":
                        strBookTags = str(book.Tags)
                        strSQLcolumns = strSQLcolumns + ", \"Tags\""
                        strSQLvalues = strSQLvalues + ", \'" + strBookTags + "\'"
                  strSQL = strSQLcolumns + strSQLvalues + ")"
                  objSQLCommand = OdbcCommand(strSQL, objConnMDBComicBase)
                  objSQLCommand.ExecuteNonQuery()[/code]

Thanks again for the assistance and enjoy the points!
