Visual Expert for Oracle PL/SQL

Visual Expert Features

Navigation in the application

With Visual Expert's treeview, explore your PL/SQL components (Packages, functions, procedures, blocks, triggers...) and their relationships.

With Visual Expert code browser, navigate in your code like you never did before: any reference found in the code comes with a hyperlink to jump to the referenced item.

Global impact analysis

If you need to change a stored procedure, a table, a column... Visual Expert can list all components related to this item. This will help you evaluate the consequences of the change.

For instance, you can ask for all triggers, cursors, functions and procedure including SQL statements using a DB column, as well as a %rowtype definition.

In case you developed PowerBuilder applications any PowerBuilder-to-PL/SQL reference is also taken into account.

Visual Expert for Oracle Stored Procedures detailed features

CODE
EXPLORATION
Stored Procedures

After analysing your project, Visual expert may display several lists of Procedure:
* List of the procedures defined in your project
* List of the procedure referenced by your project (no matter if the code is included in the project)
* Procedure by Access type (Procedure including Delete, Update, Insert or Select Statements)
* Procedures which name and/or source code contain a given string
* Procedure called by PowerBuilder Components(1)

(1) This requires Visual Expert for PowerBuilder

SQL Queries After analysing your project, Visual expert may display several lists of Procedure:
* SQL statements defined in the project.
* SQL statements by access type (select, insert, update or delete Statements).
* SQL statements by definition type = defined in PL/SQL code, PowerBuilder Script(1) or Datawindow (1).
* SQL statements containing a given string (text search focused on the SQL statements of the project).

(1) This requires Visual Expert for PowerBuilder

You may also select packages, procedures, functions, block, triggers or cursors and list all SQL defined in the selected items.
See an example
Code Architecture First, you may select one or several packages, procedures, functions, block, triggers or cursors.
Then Visual Expert will open a treeview with the architecture of the code of the selected items.
See an example
Hyperlink
Exploration
When displaying your code, Visual Expert adds a hyperlink for each reference found.
Clicking on this hyperlink will open the source code of the referenced item.
PL/SQL
Components
Lists of the Packages, Procedures, Functions, Blocks, Triggers, Cursors and Aliases defined in the application.
Each list open in Visual Expert treeview.
See an example
String search You may search for a string in your project. Several options are available:
* Global Search in the whole project (including PL/SQL code, PowerBuilder Code, SQL files, ...).
* Search restricted to a given type of component (For instance, you may search for triggers only).
* You may search in the name and/or the source code of components.
* You use regular expressions in a search (click here to read about regular expressions).
* You may search into a selection of components (for instance after selecting some procedures in the treeview).
IMPACT ANALYSIS

(cross-references)
Table and Columns First, you can select a table or column.
Then, Visual Expert will list the procedures, functions, block, triggers, cursors... referencing this table or column.
See an example
If you also develop with PowerBuilder, all PB references are included in the result

PL/SQL Procedures
and Functions
Visual Expert can also list all PL/SQL components calling a procedure or a function.

PL/SQL parameters
and variables
Same concept: Visual Expert can find any reference to PL/SQL variables and parameters.
Oracle Datatypes Visual Expert can list all variables or parameters declared with a given datatype.
For instance which variables and parameters are created with the VARCHAR2 datatype.
See an example
Oracle Functions You may need to know where a given Oracle function is used (such as Count, decode, to_char...).
Visual Expert will list every calls to such a function.
See an example

References
Procedures and
Functions referenced
First, you may select one or several packages, procedures, functions, block, triggers or cursors.
Then Visual Expert will list all Procedures and functions, cursors and variables referenced by the selected items.
