Inheritance
Properties
| name | default | description |
| digits | n/a | This property is taken from the repository configuration. |
| sql_counter | n/a | REQUIRED. This property is taken from the repository configuration. |
Required Phrases
No additional phrases.
Database
Counter fields are stored in the database as
fieldname INT(11)
API

Examples
Most basic example. sql_counter is required but typically would be set to the same as name.
{
name => "mycounter",
type => "counter",
sql_counter => "mycounter"
}
Typically, you would not want to allow a value for this field to be imported or cloned as it is an auto-incremented field.
{
name => "subjectcounter",
type => "counter",
required => 1,
import => 0,
can_clone => 0,
sql_counter => "subjectcounter"
},
