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 (see the Overview provided by Microsoft).

The ISAM OLEDB type must be put in square brackets and and with a semicolon like in this example for an Microsoft Excel workbook:

SELECT *
  FROM [...] 
    IN '...'[EXCEL 8.0;];

If you need to specify optional parameters they have to be appended to the ISAM type:

SELECT *
  FROM [...] 
    IN '...'[EXCEL 8.0;HDR=yes;IMEX=0;];

-== Microsoft Access ==
-This allows you to easily refer to other database tables and queries
-without the need to create a linked table.
-The database can be specified by the use of the IN clause
-<syntaxhighlight lang="sql" highlight="3">
-SELECT *
-  FROM tblTable
-    IN 'c:\source.mdb'
-</syntaxhighlight>
-or by applying square brackets around the database path and prefixing the
-referenced table with it
-<syntaxhighlight lang="sql" highlight="2">
-SELECT *
-  FROM [c:\source.mdb].tblTable
-</syntaxhighlight>
-== Microsoft Excel ==
-Every worksheet or (named) range is considered as table when accessing Microsoft Excel files.
-<syntaxhighlight lang="sql" highlight="3">
-SELECT *
-  FROM [...]
-    IN 'c:\source.xls'[EXCEL 8.0;];
-</syntaxhighlight>
-=== Named Range ===
-Accessing data by naming ranges allows the developer to specify exactly what should be imported.
-By this&mdash;and the optional parameters&mdash;it should be easy to retrieve exactly
-the desired data and nothing else.
-<syntaxhighlight lang="sql" highlight="2">
-SELECT *
-  FROM [NamedRange]
-    IN 'c:\source.xls'[EXCEL 8.0;];
-</syntaxhighlight>
-=== Worksheet ===
-The selection of worksheets is usually not recommended, as the selection will also
-contain empty cells and maybe other unwanted content.
-<syntaxhighlight lang="sql" highlight="2">
-SELECT *
-  FROM [Worksheet$]
-    IN 'c:\source.xls'[EXCEL 8.0;];
-</syntaxhighlight>
-=== Reference ===
-In rare cases it is necessary to retrieve the content of a certain cell range.
-<syntaxhighlight lang="sql" highlight="2">
-SELECT *
-  FROM [Worksheet$A1:B2]
-    IN 'c:\source.xls'[EXCEL 8.0;];
-</syntaxhighlight>
-=== Optional Parameters ===
-;HDR
-:The header parameter specifies, whether the first row should be interpreted as column headers.
-:Possible values: HDR=yes, HDR=no
-;IMEX
-:In order to identify the content of a column usually the first eight rows are scanned for values and the rest of the column is identified accordingly.
-:Unfortunately this behaviour often leads to misinterpretation and error values.
-:Setting this parameter to ''0'' suppresses the value type interpretation and enforces the data type "text" for all columns.
-:Possible values: IMEX=0
-== Text file ==
-When dealing with text files the folder of the file is interpreted as database
-and the text file itself as table source.
-It is possible&mdash;and highly recommended&mdash;to specify the content
-of the text file by creating a ''schema.ini'' with the specification details.
-<syntaxhighlight lang="sql" highlight="2-3">
-SELECT *
-  FROM source.csv
-    IN 'c:\'[TEXT;];
-</syntaxhighlight>
-=== Optional Parameters ===
-;HDR
-:The header parameter specifies, whether the first row should be interpreted as column headers.
-:Possible values: HDR=yes, HDR=no
-== HTML ==
-While this works theoretically in general, there are many problems with selecting data from web sites. These [http://ewbi.blogs.com/develops/2006/12/reading_html_ta.html HTML specifica] make it impracticable to work with HTML tables this way.
-== Microsoft Exchange ==
-It is possible to query Exchange / Outlook folders and address books as follows:
-<syntaxhighlight lang="sql" highlight="2-3">
-SELECT *
-  FROM Inbox
-    IN 'c:\temp\'[Exchange 4.0;MAPILEVEL=Account - Paul Stevens|;TABLETYPE=0;];
-</syntaxhighlight>
-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.
