Inherit dictionary rules

Form Section and Canvas Section controls can 'inherit' the Data Dictionary rules. This populates the control's relevant attributes with the settings from the Data Dictionary.

Section: Inherit dictionary rules

By default, controls have the Inherit dictionary rules attribute set to True, but the containing Form and Canvas Sections have the attribute set to False.

To enable dictionary inheritance for all the controls in a Section, set the Section's attribute to True.

Field: Inherit dictionary rules

The attributes of the controls will be populated with the dictionary settings (save and reload the App).

Inherit dictionary rules can then be disabled for individual controls as required.

Remember, enabling Inherit dictionary rules for the control has no effect unless Inherit dictionary rules for the control's containing Section is enabled.

Default

Default

The Default attribute is available in Form Section and Canvas Section fields and Grid Section columns.

It specifies the default value for the field when a new record is added or the initial value of a memory variable data source.

Default

Here the orders.orderdate is populated with the system date when a new record is added.

Default

Double-click the header of a column in a Grid Section to access the Column Attributes.

Default

Here again the orders.orderdate is populated with the system date when a new record is added.

A Default has also been set on the orders.orderid field using the SEQNO() function to generate a unique sequential number.

The orders.customerid field automatically inherits the current customers.customerid value due to the Relationship Builder relation set between the customers Form Section and the orders Grid Section (key: customerid).

Data Dictionary: Default

The Default attribute corresponds to the Default Column Constraint stored in the table's Data Dictionary.

Modify a Column: Default

The Default Column Constraint can be set in the Create a Column and Modify a Column dialogs in the Data Workspace and Page Builder.

It can also be specified in the CREATE TABLE and ALTER TABLE commands.

// Mandatory
ALTER TABLE "orders" MODIFY CONSTRAINT ORDERDATE SET DEFAULT date()

Mandatory

Attempting to save a record without entering non-empty data in a field with the Mandatory input attribute set returns an error message and the record is not saved.

Note: 0 is considered an empty numeric value.

Data Dictionary: Not Null

The Mandatory input attribute corresponds to the Not Null Column Constraint stored in the table's Data Dictionary.

Modify a Column: Mandatory / Not Null

The Mandatory / Not Null Column Constraint can be set in the Create a Column and Modify a Column dialogs in the Data Workspace and Page Builder.

It can also be specified in the CREATE TABLE and ALTER TABLE commands.

// Mandatory
ALTER TABLE "customers" MODIFY CONSTRAINT CUSTOMERID SET NOT NULL
// Not Mandatory
ALTER TABLE "customers" MODIFY CONSTRAINT CUSTOMERID SET NULL
