Príkaz jazyka PL/SQL.

Syntax


PROCEDURE ADD_GROUP_ROW
(recordgroup_id RecordGroup,
row_number NUMBER);
PROCEDURE ADD_GROUP_ROW
(recordgroup_name VARCHAR2,
row_number NUMBER);

Popis


Adds a row to the given record group.

Built-in Type unrestricted procedure
Enter Query Mode yes

Parameters


  • recordgroup_id The unique ID that Form Builder assigns when it creates the group. The data type of the ID is RecordGroup.
  • recordgroup_name The name you gave to the record group when creating it. The data type of the name is VARCHAR2.
  • row_number A whole number that specifies a row in the group. If you add a row to any but the last position in a group, all rows below that are logically renumbered. To add a row to the end of a group, use the END_OF_GROUP constant.


Error Conditions


Form Builder returns a runtime error given either of the following conditions:
  • If you enter the name of a non-existent record group.
  • If you supply a row number that is out of range or is invalid (for example, an alphabetic character).
