One year ago I presented here the possibility how to export SAP table content as SQL descriptions to import it to SQLite containers. Here a complementation to use the full bandwith with ActiveX Data Objects (ADO) and Open Database Connectivity (ODBC).

To use SQLite via ODBC you must install a special driver. You can find a very good one here, it is free and released under BSD-type license. Now you can use SQLite databases with ABAP.

Here an example how to create and use an SQLite database:
"-Begin-----------------------------------------------------------------
Report ZODBC_SQLITE.

Constants adUseClient Type i Value 3.

Data:
oCon Type OLE2_OBJECT,
oRecSet Type OLE2_OBJECT,
oFields Type OLE2_OBJECT,
oField Type OLE2_OBJECT,
cntRec Type i,
cntFields Type i,
sSQL Type String,
i Type i,
j Type i,
nameField Type String,
valueField Type String.

Create Object oCon 'ADODB.Connection'.
If sy-subrc <> 0 Or oCon-Handle <= 0 Or oCon-Type <> 'OLE2'.
Exit.
EndIf.

Set Property Of oCon 'CursorLocation' = adUseClient.

Call Method Of oCon 'Open' Exporting
#1 = 'DRIVER=SQLite3 ODBC Driver;Database=C:\Dummy\MyDb.db3;'.

sSQL = 'DROP TABLE tblTest'.
Call Method Of oCon 'Execute' Exporting #1 = sSQL.

sSQL = 'CREATE TABLE tblTest(ID INTEGER PRIMARY KEY, NAME VARCHAR(40))'.
Call Method Of oCon 'Execute' Exporting #1 = sSQL.

i = 1.
While i <= 16.
sSQL = 'INSERT INTO tblTest VALUES(' && i && ', ''Name' && i && ''')'.
Call Method Of oCon 'Execute' Exporting #1 = sSQL.
i = i + 1.
EndWhile.

sSQL = 'SELECT * FROM tblTest'.
Call Method Of oCon 'Execute' = oRecSet Exporting #1 = sSQL.

Get Property Of oRecSet 'RecordCount' = cntRec.
i = 1.
While i <= cntRec.
Get Property Of oRecSet 'Fields' = oFields.
Get Property Of oFields 'Count' = cntFields.
j = 0.
While j <= cntFields - 1.
Get Property Of oFields 'Item' = oField Exporting #1 = j.
Get Property Of oField 'Name' = nameField.
Get Property Of oField 'Value' = valueField.
Write: / nameField, ` `, valueField.
j = j + 1.
EndWhile.
Call Method Of oRecSet 'MoveNext'.
i = i + 1.
EndWhile.
Call Method Of oCon 'Close'.
Free Object oCon.

"-End-------------------------------------------------------------------

It is not necessary to build another library, with the existing possibilities like ADO and ODBC you can connect and use many different databases of different manufacturers with ABAP.
