Although you can do a fine job building applications with bound forms, using Visual Basic for Applications (VBA) code to access and manipulate data directly provides far greater flexibility than a bound application can. Anything that can be done with bound forms and controls can be done with a bit of VBA code using ActiveX Data Objects (ADO) or Data Access Objects (DAO) to retrieve and work with data.

The VBA language offers a full array of powerful commands for manipulating records in a table, providing data for controls on a form, or just about anything else. This chapter provides some in-depth examples of working with procedures that use SQL and ADO to manipulate database data.

Note

In the Chapter13.accdb database, you'll find a number of forms to use as a starting point and other completed forms to compare to the forms you change in this example.

Understanding SQL

Many of the VBA procedures that you write for working with Access data utilize Structured Query Language (SQL) statements to retrieve data from a database, add new data to a database, or update records in a database. When you use the Access Query Designer to create a query, Access converts the query's design into a SQL statement. The SQL statement is what Access ...
