DISPLAY LIKE attribute
The DISPLAY LIKE
attribute applies column
attributes defined in the database schema files (.att)
to a field.
Syntax
DISPLAY LIKE [table.]column
- table is the optional table name to qualify the column.
- column is the name of the column to be used to retrieve display attributes.
Usage
Specifying this attribute is equivalent to listing all the attributes that are assigned to table.column in the database schema file with the .att extension.
Display attributes are automatically taken from the schema file if the field is linked to table.column in the field name specification.
The DISPLAY LIKE
attribute
is evaluated at compile time, not at runtime. If the database schema
file changes, recompile all forms using this attribute. Even if all
of the fields in the form are FORMONLY
, this attribute
requires the form compiler to access the database schema file that
contains the description of table.
Example
EDIT f001 = FORMONLY.fullname, DISPLAY LIKE customer.custname;
