A default is a value that Adaptive Server inserts in a table column when a row of data is inserted and no value is provided for the column. Once you create a default, you can bind it to table columns and to user datatypes.
Only a database owner or a user with create default permission can create a default.
Creating a default
In a database, select the Defaults folder.
Select File | New | Default (wizard). The Default Creation wizard opens.
Enter a name for the default.
Accept the default owner or choose a different owner from the drop-down list.
In the Default Expression box, enter a SQL expression for the default. The expression is the text that would follow the as keyword in a create default command.
Click OK.
You can also create a default using the Add Default
(Template). Select Defaults and double-click Add Default (Template).
Select the Defaults folder. In the right pane double-click the Add Default (wizard) icon.
