2 Using the SQLCONNECT environment variable settings if any command
line values are missing. Adaptive Server IQ database utilities do not set
this variable automatically. For a description of the SQLCONNECT
environment variable, see Chapter 1, “Environment Variables and
Registry Entries,” in Adaptive Server IQ Reference Manual.
3 Prompting you for a user ID and password to connect to the default
database on the default server, if parameters are not set in the command
line or the SQLCONNECT environment variable.
For a description of command-line switches for each database utility, see
Chapter 4, “Database Administration Utilities” in the Adaptive Server IQ
Reference Manual.
Working with ODBC data sources
You can store a set of Adaptive Server IQ connection parameters as a data
source. Data sources are required to use applications that connect using the
Open Database Connectivity (ODBC) interface.
Microsoft Corporation defines the ODBC interface, which is a standard
interface for connecting client applications to database management systems in
the Windows and Windows NT environments. Many client applications,
including application development systems, use the ODBC interface to access
a wide range of database systems.
Although data sources are especially designed for Windows and Windows NT,
Adaptive Server IQ allows you to create and use them on UNIX servers as well.
This allows ODBC–based client applications to connect to databases on UNIX
servers.
When you connect to a database using ODBC, you use an ODBC data source.
The data source contains a set of connection parameters. You need an ODBC
data source on the client computer for each database you will connect to.
If you have a data source, your connection string can simply name the data
source to use.
Embedded SQL can
use data sources Embedded SQL applications such as Interactive SQL and the other Adaptive
Server IQ database administration utilities can also use ODBC data sources,
even though they are not ODBC applications.
