General
It is possible to access some resources without writing any line of code. All you need is to write a query which makes use of ISAM OLEDB.
For further reading:
Microsoft Access
Tables and Queries
SELECT *
FROM tblTable
IN 'c:\source.mdb'
This allows you to easily refer to other databases' tables and queries without the need to create a linked table.
Microsoft Excel
Named Range
SELECT *
FROM [NamedRange]
IN 'c:\source.xls'[EXCEL 8.0;];
Accessing data by naming ranges allows the developer to specify exactly what should be imported. By this—and the optional parameters—it should be easy to retrieve exactly the desired data and nothing else.
Worksheet
SELECT *
FROM [Worksheet$]
IN 'c:\source.xls'[EXCEL 8.0;];
Reference
SELECT *
FROM [Worksheet$A1:B2]
IN 'c:\source.xls'[EXCEL 8.0;];
Optional Parameters
- HDR
- IMEX
Text file
SELECT *
FROM source.csv
IN 'c:\'[TEXT;];
Optional Parameters
- HDR
HTML
While this works theoretically in general, there are many problems with selecting data from web sites. These HTML specifica make it impracticable to work with HTML tables this way.
Exchange
It is possible to query Exchange / Outlook folders and address books as follows:
SELECT *
FROM Inbox
IN 'c:\temp\'[Exchange 4.0;MAPILEVEL=Account - Paul Stevens|;TABLETYPE=0;];
where Account - Paul Stevens has to be replaced by the exact name of the Inbox followed by the pipe (|). This works for Contacts, Calendar and other folders too.
ODBC
ODBC is considered as deprecated technology and does nothing which OLEDB is not capable of, but for the sake of backwards compatibility it is possible to use ODBC connections too.
Optional Parameters
The optional parameters can be appended to the required part in the brackets. Example:
[EXCEL 8.0;HDR=yes;IMEX=0;]
HDR
Does the data source have headings?
- Values: yes|no
- Default: yes
IMEX
Should the data be imported "as is" in text format or should windows try to guess the value type of each column?
- Values: 0|1
- Default: 1 (guess)
