The Connection
String Builder - Save Password dialog appears, as shown in Illustration

Illustration 20: Connection String Builder - Save Password
Dialog
Here we can select Yes if we wish to save the logon /
password information within the connection string we are building (as
appropriate).
NOTE: Saving logon information in connection
strings carries inherent risk. Security of the data source may be compromised
by doing so. For more information, consult the MS Access documentation, MSSQL
Server 2000 Books Online, or other resources. Not saving the information
will result in our being asked for logon / password information each time we
attempt to access the back-end via MS Access.
Since
mine is a development environment, I will save the information, but you may do
as you see fit for your own environment.
37.
Answer the
dialog by selecting Yes or No, as appropriate to your
environment.
We are
returned to the Query Properties page, where we see the new string specification
appear in the ODBC Connect Str box, as shown in Illustration 21.
Illustration 21: Query Properties Page - New Connection
Information in Place
Another property that is of significance within our intended
use of the Pass-Through query channel is the Returns Records setting.
We will leave this setting at its default of Yes (as indicated in Illustration
21) for the Stored Procedure we will execute in our first example. This is
because the procedure we will use is designed to return records, in a
report-like manner, for viewing at the client level. In cases where the
procedure is intended to perform an action other than the simple return of a
recordset, we change the Return Records setting to No. If we
leave it at the default of Yes in a case where records are not returned,
we receive an error message.
38.
Close the Query
Properties page.
We are
now ready to work with a Stored Procedure.
