Main Features
Navigation in the application
With Visual Expert's treeview, explore your Transact-SQL components (functions, procedures, blocks, triggers...) and their relathionships.
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.
Impact analysis
If you need to change a stored procedure, a table, a column... Visual Expert can list all components related to this item. You can then evaluate the consequences of the change and avoid negative side effects.
For instance, you can ask for all triggers, cursors, functions and procedure including SQL statements using a DB column.
In case you developed PowerBuilder applications any PowerBuilder-to-Transact-SQL reference is also taken into account.
Why use Visual Expert
Avoid unexpected Side Effects after a change
When you modify the source code of the application, there is always a risk of regression and errors due to the modifications. In a click Visual Expert helps you perform an impact analysis on any component of the application you are about to modify
Share the knowledge of your application
Visual Expert makes it easier to navigate, no matter how complex the application is.
Visual Expert helps you gain time in the development and maintenance.
It facilitates the integration of new developers.
When someone is not available, any member of the team can understand and master his code.
Visual Expert allows you to :
- Discover the application structure and its components
- Explore the inheritance tree and master the framework,
- etc...

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 accessing the DBMS (default case)
* SQL statements not accessing the DBMS (like "select @lr_code1=@lr_code2*100")
* SQL statements containing a given string (text search focused on the SQL statements of the project)
* SQL statements by access type (select, insert, update or delete Statements)
* SQL statements by definition type = defined in Transact-SQL code, PowerBuilder Script(1) or Datawindow(1)
(1) This requires Visual Expert for PowerBuilder
You may also select one or several procedures, functions, blocks, triggers or cursors
and list the SQL statements defined in the selected items.
SQL Queries
After analysing your project, Visual expert may display several lists of Procedure:
* SQL statements defined in the application
* SQL statements containing a given string (text search focused on the SQL statements of the project).
* SQL statements by access type (select, insert, update or delete Statements)
* SQL statements by definition type (defined in PowerBuilder Script, Datawindow, Transact-SQL code(1) or PL/SQL code(2) ).
(1) requires Visual Expert for Transact-SQL
(2) requires Visual Expert for PL/SQL
Code Architecture
First, you may select a one or several procedures, functions, blocks, triggers or cursors.
Then Visual Expert will open a treeview with the architecture of the code for 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
Transact-SQL Components
On top of Procedures and SQL statements, Visual Expert can list the following Transact-SQL components:
* Transact-SQL Triggers
* Transact-SQL Cursors
* Transact-SQL Views
* Transact-SQL Blocks
* ...
String search
You may search for a string in your project. Several options are available:
* Global Search in the whole project (including Transact-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
* 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, blocks, triggers, cursors... referencing this table or column.
If you also develop with PowerBuilder, all PB references are included in the result
Transact-SQL Procedures
Visual Expert can also list all references in your project to a procedure or a function.
If you also develop with PowerBuilder, all PB references are included in the result
Transact-SQL parameters and variables
Same concept: Visual Expert can find any reference to Transact-SQL variables and parameters
Database Functions
You may need to know where a given SQL Server function is used (such as Count, sum,...). Visual Expert will list every calls to such a function.
TRANSACT-SL REFERENCES
Procedures and Functions referenced
First, you may select one or several procedures, functions, blocks, triggers or cursors.
Then Visual Expert will list all Procedures and functions, cursors and variables referenced by the selected items.
Transact-SQL Cursors
Visual Expert can also list the Transact-SQL cursors referenced by procedures, functions, triggers or cursors
Transact-SQL parameters and variables
You may list all variables and parameters referenced in procedures, functions, block, triggers or cursors.
Calls from PowerBuilder Objects to Transact-SQL Procedures
If you also develop with PowerBuilder, you may list all references from PowerBuilder objects to Transact-SQL:
* per PBL (list of the Stored procedures called by each PBL)
* per Object (list of the Stored procedures called by each PowerBuilder Object)
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 Transact-SQL code.
Temporary tables
You may list all temporary tables created or referenced by Transact-SQL code.
You may then list which Transact-SQL procedure is accessing this temporary table.
Tables created
You can list all tables created by DDL statements found in your code.
(this list may include temporary and non temporary tables)
DB System Functions
You can list System Functions (Count, Sum, GetDate...), System Variables (@@SqlStatus, @@RowCount,...) and System Procedures (sp_procxmode) used in your project.
You can also list all references to such functions and variable from your Transact-SQL code.
