Connecting to a database from DBISQL

Many examples and exercises throughout the documentation start by
connecting to the sample database from Interactive SQL, also called DBISQL.
Here is how to carry out this step.

Note

To avoid ambiguity, specify connection parameters for DBISQL instead

of relying on defaults. You can specify connection parameters in a command
line or an initialization file such as .odbc.ini or odbc.ini. For a complete list, see
Chapter 3, “Connection and Communication Parameters” in Adaptive Server
IQ Reference Manual
.

If more than one database is started on a server, for example, you should
specify the database name. In a network with subnets, specify the

CommLinks

parameter with protocol options including the host number.

In the .odbc.ini file, you must use the long form of each parameter. For
example, use DatabaseFile instead of DBF.

If your parameters are incomplete or incorrect, you may see an error such as

Database name required to start engine

To connect from a UNIX system:

1

Make sure that your PATH and other environment variables are correctly
set, as described in Chapter 1, “File Locations and Installation Settings” in
the Adaptive Server IQ Reference Manual.

2

To ensure that the sample database is loaded on a running server, at the
UNIX prompt enter:

ps -eaf | grep asiqdemo

If you need to start the sample database, enter:

cd $ASDIR/demo

start_asiq @asiqdemo.cfg asiqdemo

If you have not already done so, change to your home directory ($HOME)
and issue the following command to copy the terminfo extension file
default.tix into it:
