Visual Expert for Oracle Features

Find references (Impact Analysis)

Avoid regression bugs: if you need to change any items in your application (procedure, table, column, variable...) Visual Expert can list all components related to this item. You can then evaluate the consequences of the change and avoid unexpected side effects.

For instance, you can find all SQL, triggers, functions and procedure using a given column.

Understand and Maintain complex PL/SQL code

When maintaining large, old and complex applications, you may need to understand code you’re not familiar with. In such cases, Visual Expert is the perfect companion for your development tool:

  • Its treeview let you explore PL/SQL components and their dependencies.
  • Its code browser transforms and enriches your code for a new experience: all references become hyperlinks pointing at the referenced item, and tooltips display more information about each code item.

Easily explore the code structure and components.

Review and clean-up PL/SQL code

Visual Expert scans your code to provide the following services:

  • Calculate the number of PL/SQL Lines of Code in your application
  • Identify dead code (objects, tables, index, procedures…that are never referenced)
  • Find possible issues in your code: procedures or functions with no code inside, or exceeding a given size, duplicated, with missing comments, etc.

Improve SQL performances

While scanning your code, VE can suggest changes at coding level that will improve SQL performances. For instance, it can find the columns used in “Where” clauses, group by, etc., that don’t have any Index yet.

You can then anticipate performances issues very early in the development cycle, without waiting for testing, profiling or even production…

Document your code

Generate a complete and customized documentation of your PL/SQL code.
Easily transfer the knowledge of your application.
Navigate between objects using hyperlinks in the documentation.

You can customize the content and presentation of your documentation, and Schedule it to generate it automatically on a regular basis.

See an example documentation here.

Advanced String Search

With large volumes of code, string searches often return too many results, making such searches tedious and non-productive. Visual Expert addresses this issue as follows:

  • Use multiple search criteria to reduce the result
    • Restrict search to comments only
    • Restrict search to one or several object types
    • Search for exact words, or words starting/ending with…
    • Search with regular expressions
    • Match case
  • Search into several databases at the same time
  • Include any text files in the search (SQL, java source, shell scripts, ascii..)
  • Analyze the result with advanced exploration features
  • Share results between team members

Detailed Features

Impact Analysis

Cross-References

  • Tables 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.
    If you also develop with PowerBuilder, all PB references are included in the result (read more about Visual Expert for PowerBuilder)
  • PL/SQL Procedures and Functions
    Visual Expert can also list all PL/SQL components calling a procedure or a function.
    See an example
    If you also develop with PowerBuilder, all PB references are included in the result
    (read more about Visual Expert for PowerBuilder))
  • PL/SQL parameters
    Same concept: Visual Expert can find any reference to PL/SQL variables and parameters. and variables
  • 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.
  • 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 call to such a function.

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.
  • 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.
  • 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 opens in Visual Expert treeview.
  • 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).

PL/SQL 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.
  • PL/SQL Cursors
    Visual Expert can also list the PL/SQL cursors referenced by packages, procedures, functions, block, triggers or cursors.
  • PL/SQL parameters and variables
    You may list all variables and parameters referenced in packages, procedures, functions, block, triggers or cursors.
  • Calls from PowerBuilder Objects to PL/SQL Procedures
    If you also develop with PowerBuilder, you may list all references from PowerBuilder objects to PL/SQL:
    * per PBL (list of the Stored procedures called by each PBL)
    * per Object (list of the Stored procedures called by each PowerBuilder Object) (read more about Visual Expert for PowerBuilder)

Database References

  • Table and Columns referenced
    While reading your code, Visual Expert will extract and analyse the SQL queries in your code. As a result, you can list all table and columns referenced by your PL/SQL code.
  • Aliases
    Visual Expert can also list the aliases used in your SQL queries.
  • Oracle Functions
    You can list all Oracle system function (such as Count, Decode, To_char...) used in your PL/SQL code.
