INSERT - field_group
Other versions: 7.31 | 7.40 | 7.54
Obsolete Syntax
INSERT dobj1 dobj2 ... INTO { header | field_group }.
Effect
This statement is used to build a structure of a field group of the
extract dataset of
the program, where the field group is defined using FIELD-GROUPS
. A list of global
flat data objects dobj
can be inserted after INSERT
. Specifying local data objects raises an exception.
The list defines the components of the field group header
or field_group
.
Any name can be specified directly for field_group
, whereas header
is a predefined name of a special field group whose components are automatically a part and a key of
all other field groups. The components of a field group have the function of a pointer to data objects
whose contents can be attached as a line to the extract dataset when executing the statement EXTRACT
.
The statement INSERT
can be used in any
processing block of
a program and is executed at the given time during the program execution. A field group can have different
INSERT
statements. Additional components can be added to a field group until
the first corresponding line with EXTRACT
is attached to the extract dataset.
More specifically, components can only be added to the field group header
until a field group of the program is extracted because it is a part of all field groups. An INSERT
statement for an already extracted field group raises a non-handleable exception.
Field symbols can be specified for dobj
but not dereferenced data references.
A field symbol is ignored if no data object is assigned to it. Specifying a data reference raises a non-handleable exception.
Notes
-
A field group
field_group
to which no fields are explicitly added still contains the field of the special field groupheader
. -
In global classes, no field groups can be defined or edited. In methods of local classes of programs other than class pools, the statement
INSERT
is possible for globally defined field groups. -
Extracts are obsolete. Internal tables are recommended instead.
Example
In this example, three field groups are declared in the global declaration part of an
executable program
and its components are specified in the event block START-OF-SELECTION
. The
field group flight_info
contains five components of the field group
header and its own. The field group flight_date
contains only the components of the field group header
.
