One of the benefits of Access from a programmer's perspective is its relative compatibility with SQL (structured query language)—queries can be viewed graphically or edited as SQL statements, and SQL statements can be used directly in Macros and VBA Modules to manipulate Access tables. Users can mix and use both VBA and "Macros" for ...
As an example, VBA code written in Microsoft Access can establish references to the Excel, Word and Outlook libraries; this allows creating an application that – for instance – runs a query in Access, exports the results to Excel and analyzes them, and then formats the output as tables in a Word document or sends them as an Outlook email.
Named variables and user-defined functions. Using VBA, the user can add their own functions and subroutines that refer to these named ranges. In the figure at the right, the function sq is created in the Visual Basic editor supplied with Excel, and x & y are named variables in the spreadsheet.
There are small inconsistencies in the way VBA is implemented in different applications, but it is largely the same language as Visual Basic 6.0 and uses the same runtime library. Visual Basic development ended with 6.0, but in 2010 Microsoft introduced VBA 7 to provide extended features and add 64-bit support. [31]
To start a new table row, type a vertical bar and a hyphen on its own line: "|-". The codes for the cells in that row start on the next line. An id for § anchoring in-links, and § row style may be included on the same line. {| |+ The table's caption |-row code goes here |-next row code goes here |}

AutoNumber is a type of data used in Microsoft Access tables to generate an automatically incremented numeric counter. It may be used to create an identity column which uniquely identifies each record of a table. Only one AutoNumber is allowed in each table. The data type was called Counter in Access 2.0. [1]
The functions are simple data validation and data type checking functions. The data validation functions determine whether it is possible to convert or coerce the data value given as an argument to the function to the type implied by the function name, and return a Boolean value recording whether it was possible or not.
