Database Interface
Using Sybase
You need to install the AsaClient provider on your computer; the tests with IWS were performed using the
architecture explained in the topic Linking the Database Through a Remote DB Provider.
If you are using the browse button to automatically generate the connection string, the string returned will
have the following format:
Provider=ASAProv.90; Data Source=Test
This format requires that you create an ODBC DSN with the same name as the Data Source (in this case, Test)
in order to communicate with the database. If the DSN is not created, the following error will display in the
LogWin when connecting to the database:
Database: Error: Parse error: DSN 'Test' does not exist
To void an ODBC DSN, you can enter with the connection string manually as shown in the example below:
Provider=ASAProv.90; DBF=C:\ Test.db
Note: These procedures were tested using Sybase Server Anywhere 9.0.1.1751.
Using Microsoft Excel
IWS's database interface lets you store information in and retrieve information from Microsoft Excel
spreadsheet (XLS or XLSX) files.
You do not need to have Excel installed on the same computer as IWS; IWS can directly read from and write
to an existing XLS/XLSX file. However, you do need to use Excel to create the initial file — either a blank
spreadsheet for new data or a populated spreadsheet for reference data. Once you've created the file, you can
move it to any location and establish a connection to it there.
Note: This procedure was last tested using Microsoft Excel 2007 (12.0.6331.5000).
To establish a connection between your IWS project and your XLS/XLSX file:
1. In the Database Configuration property sheet, click the Browse button (…).
