Creating and Editing Packages
A package is a group of procedures, functions, variables, and SLQ statements, used to store together related objects.
Packages contain all the information needed to process SQL statements from a single source file. You can use
packages to process and call batches of SQL. They are not associated with a particular table; they are stored in the
database.
The following database platforms support packages:
• Oracle 7.x, 8.x, 9i, 10g, and11g
Create a Package
1 In the Data Model Explorer, expand the Logical Main Model, right-click the Packages node, and then click New
Package.
2 Complete the Package Editor and then click OK to create the package.
TIP: Once you have created the auxiliary table, you can edit it by right-clicking the package you want
to change, and then clicking Edit Package.
TIP: The Package Editor includes find and replace functionality for working with SQL text strings.
The following describe options that require additional explanation.
Header tab
Body tab
The header contains the package specification. Here you can declare types, variables, constants, exceptions,
cursors and subprograms. The header does not contain any code. You can specify a package that contains only
global variables that will be used by subprograms or cursors. This type of package declares only types,
constants, variables, exceptions, and call specifications and does not require a package body.
The package body provides the implementation for the subprograms and the queries for the cursors declared in
the header.
Definition tab
Enter or edit a definition for the package. If the target database supports it, ER/Studio adds this definition as a
comment when generating SQL code.
Attachment Bindings tab
Bind an external piece of information, or attachment to the package. You can also remove an attachment from an
object, override an attachment binding’s default value, or change the position of a bound attachment. To override
the value of the attachment you have moved to the Selected Attachments grid, double-click the Value field of the
target attachment. ER/Studio opens the Value Override Editor or a list depending on the attachment datatype.
Attachments are created in the Attachments folder of the Data Dictionary. For more information, see Attaching
External Documents to the Data Model.
